In Part 1 I covered network implants: the little boxes a red teamer plugs into your LAN. This time we’re going on a little smaller form factor tour of the gadgets that don’t look like computers at all, from a humble USB stick all the way down to a chip baked into a motherboard. Then we’ll look at how some of these things actually phone home, and finish on a thought that should make you glance at your gadgets twice.

Every one of them exploits the same assumption: that the ordinary hardware around us is exactly what it appears to be. It usually is, but sometimes “usually” is doing a lot of work you didnt ask for.

The Implant Zoo by Form Factors

The USB stick

The classic. It looks like a flash drive; it isn’t.

• USB Rubber Ducky the original BadUSB stick and still the icon. It’s a keystroke-injection tool: the computer thinks it’s a keyboard, so it trusts it to type, and the Ducky hammers out a pre-written DuckyScript payload at machine speed to open a Command and Control (C2) backdoor before anyone can react.
• Bash Bunny the Ducky’s much bigger brother. It’s a full Debian Linux computer crammed into a USB-stick shell, and its party trick is impersonating several trusted devices at once keyboard, USB Ethernet adapter, storage, serial to pull off multi-vector attacks. It runs proper pentest tooling (nmap, responder, impacket) on the device itself, boots in about seven seconds, and can mass-exfiltrate gigabytes straight onto an onboard microSD no network required, nothing to catch at the firewall. The Mark II even adds Bluetooth LE for remote triggers geofencing and more features.

The wireless dongle

• MalDuino W (~£49) a “wireless BadUSB.” Same keyboard-impersonation trick, but it hosts its own Wi-Fi web interface so you can store thousands of scripts and fire them remotely, or have one run automatically the moment it’s plugged in. No tether, no reprogramming for each job. A warm shoutout to Sunny S for gifting me this wicked device. Currently its out of stock and Im not sure if Seytonic will make more, lets hope he does dont know whats happened to that legion of a hacker? Check his youtube videos out here https://www.youtube.com/@Seytonic/videos and his video specifically about the Original Wireles BadUSB MalDuino W Video

The multitool

• Flipper Zero the friendly orange Swiss-army knife that put a lot of this capability into one pocketable gadget. Among its many tricks, its BadUSB mode does exactly what the Ducky does. It’s dropped the barrier to entry through the floor this is no longer specialist-only kit.
• Flipper + a 2.4GHz add-on = wireless keystroke injection. Bolt a cheap external nRF24 (2.4GHz) module onto the Flipper and it can run a MouseJack-style attack no cable, no USB port, nothing plugged in. Back in 2016, Bastille Networks found that a huge range of wireless keyboards and mice the cheap 2.4GHz-dongle kind, not true Bluetooth devices have USB receivers that don’t properly verify what’s talking to them, and whose mouse traffic is sent unencrypted. The upshot: an attacker up to ~100 metres away can transmit spoofed radio packets that the dongle happily accepts as genuine keystrokes, injecting commands straight into the victim’s PC over the air, through their own wireless mouse or keyboard receiver. Logitech (Unifying), Dell, Lenovo, Microsoft and others were all affected. Vendors shipped dongle firmware fixes but the better part of a decade later, plenty of unpatched receivers are still in daily use. (Fix: update your receiver’s firmware, or move to a wired or genuine-Bluetooth setup.)

(I’ve got a fun clip of a Flipper BadUSB script popping open PowerShell and making a machine announce “Wake up, Neo…” harmless, but it lands the point in about three seconds. I’ll drop the video in here.)

The everyday object

This is where it stops being a gadget you could spot and gets genuinely unsettling.

• O.MG Plug a full implant hidden inside a small USB plug, that is highly portable, small and is a Wi-Fi-controlled attack platform with full C2 for the elite edition.
• O.MG Cable the one to really sit with. It’s a normal-looking USB cable (USB-C, Lightning, micro your choice of colour and material) that behaves exactly like an ordinary cable until it’s triggered: it charges, it transfers data, it logs nothing. Then, on command, it becomes a Wi-Fi access point you drive from a browser, a keystroke injector firing at ~890 keys/second, a hardware keylogger storing hundreds of thousands of keystrokes, with geo-fencing (only fire in-scope) and self-destruct (go inert if carried off-site). Here’s the recalibrating part: a cable like this used to be nation-state kit the NSA’s COTTONMOUTH USB implant was reportedly budgeted around $20,000 a unit. The O.MG Cable does the modern equivalent for about $150. The capability didn’t just improve; it got cheap. FYI this is why some institutions tell you not to plug your phones into strange sockets and cables in Airports…

The invisible one

• Silicon / supply-chain implants the deep end. Instead of a device you plug in, the implant is part of the hardware a tiny extra component added to a circuit board during manufacturing, small enough to pass for a routine part. Nothing to confiscate at reception, nothing plugged into a port, nothing a user would ever notice. We’ll come back to how real this is shortly.

Here is a cool animation I found a long time ago of a chip implant on a server motherboard

How Do They Phone Home?

A dormant implant is just a gadget. The moment it needs to take commands or send loot back, it has to communicate and that’s usually the noisiest, most detectable thing it does, so it’s where the real design thought goes.

The clever trick most of them use is beaconing outbound. Firewalls and monitoring are built to block inbound connections, but outbound traffic is generally trusted and allowed. So the implant quietly reaches out to a command-and-control (C2) server it owns; once that channel is open, the operator sends commands and pulls data back down the same connection. Outbound to get inbound, in effect.

How it reaches out is the carrier trade-off range, bandwidth, power, and how easy it is to spot:

• Wi-Fi fast and simple to control from a nearby laptop or phone, but short range (tens of metres indoors). Great for close-access work; it means an operator or a bridge has to be in the area.
• Bluetooth / BLE even shorter range, but so ubiquitous it vanishes into the background. Perfect for triggers and geofencing rather than bulk data exactly how the Bash Bunny and O.MG kit use it.
• Cellular (LTE / 4G / 3G) the stealth option. Effectively unlimited range via the mobile network, and genuinely out-of-band: the traffic never touches the target’s network or monitoring, so there’s nothing for their defenders to see. The cost is a SIM, power draw and needing signal. (3G is being switched off across much of the world now, so modern kit leans on 4G/LTE.)
• LoRa the wildcard. Tiny bandwidth, but huge range (kilometres, line-of-sight). Useless for streaming, perfect for a low-and-slow beacon or trigger “I’m alive,” “activate,” or dribbling out a few credentials at a time from somewhere no Wi-Fi operator could ever sit.
• No radio at all the quietest option of the lot. The Bash Bunny’s mass-exfil-to-microSD approach needs no comms channel; the operator just retrieves the device later. Nothing to intercept because nothing was ever transmitted.

The pattern worth remembering: the stealthiest implants deliberately avoid the target’s own network and carry their traffic on a channel the defender can’t see.

How Far Up Does This Go?

Here’s the uncomfortable bit for Cyber Awareness Month.

Everything above is commercial, cheap, and buildable. A small consultancy with like minded people like me can order an O.MG cable, or build our own implants from off-the-shelf parts, for pocket change. That’s the whole point of this post: the barrier is on the floor.

Now follow that logic upward. It’s been widely reported though it remains speculation, and was flatly denied by everyone named that a government in Asia attempted to compromise companies and government systems in the West by implanting tiny chips into servers at the point of manufacture. That specific story was never proven and is firmly disputed, so treat it as exactly that: unconfirmed.

But the category is not in doubt. Chip and hardware-level implants are 100% real, some leaked government tooling has been documented to have purpose-built hardware implants for years. And the reasoning is simple: if a small consultancy with a modest budget can hide a working implant inside a USB cable, then a nation-state with effectively unlimited money, access to the manufacturing supply chain, and years of patience can absolutely hide one inside a chip. The only real question is whether anyone would ever detect it. Do you check all you devices and cables before plugging into critical systems? Sorry for making your paranoid now potentially…

Here is a punchline, If you were a well-resourced attacker and wanted the perfect implant, you wouldn’t need to smuggle anything into a building at all. You’d want a device that’s always powered, always connected to an out-of-band cellular network, packed with a microphone, camera, GPS and motion sensors, implicitly trusted, and voluntarily carried into every meeting, bedroom and secure area on earth.

That device already exists. It’s the phone in your pocket. Commercial mobile spyware has repeatedly turned ordinary smartphones into exactly that a remote bug the target bought, charges nightly, and never lets out of their sight. Arguably the most powerful implant ever deployed isn’t something an attacker plants. It’s something we all queue up to buy a few times, do you trust your mobile phone manufacturers and their governments?

What This Means for Defenders

Cybersecurity Awareness Month is the perfect excuse to make this real for your people, because the defences are refreshingly human:

• Don’t plug in things you don’t trust. Found a USB stick in the car park? It’s bait. Borrowing a stranger’s cable or charger? Just don’t if you can avoid it. This one habit kills most of the attacks above.
• Use charge-only adapters / USB data blockers on untrusted power, and carry your own cables.
• Lock down USB on endpoints device control, HID allow-listing, and alerting when a new “keyboard” or “network adapter” suddenly appears goes a long way against BadUSB.
• Treat cables, chargers and peripherals as attack surface. They’re cheap to swap and nobody inspects them there are even purpose-built malicious cable detectors now.
• Demand provenance for hardware. Buy from trusted channels, and for sensitive estates, care where your kit came from and whether it’s been tampered with in transit.
• Mind the phones. No-device policies in genuinely sensitive spaces exist for a reason.
• Train the humans. The best control against a free cable, a helpful charger or a “lost” USB stick is a workforce taught to be a little suspicious of the ordinary.

The scariest implants aren’t the ones that look like hacking tools. They’re the ones that look like the cable you’ve used every day for a year or the phone you’re probably reading this on. Stay curious, stay a little paranoid, and maybe have a proper look at what’s plugged in under your desk.

Everything here describes commercially available security-testing gear and publicly reported events, for awareness and authorised testing only. Only test against systems and hardware you own or are explicitly permitted to assess.

What Is a Network Implant?

A network implant is a covert device we drop onto the internal network during an authorised physical assessment. It sits there looking like it belongs, and phones home to us over an out-of-band channel so we have a persistent foothold inside the perimeter - no further break-in required.

Dropping one is a brilliant test of the controls most organisations assume are working:

• Network Access Control (NAC) / 802.1X - does an unknown device actually get challenged, or does it just get a DHCP lease and a route to everything?
• Rogue device detection - will anyone notice a new MAC address appear on a switch port under a desk?
• Segmentation - if the box lands in one VLAN, how far can it reach?
• Physical security - did anyone question the person in a hi-vis kneeling by the comms cabinet?

Example Evolution of Network Implant Hardware Kits

Implants have come a long way:

• Raspberry Pis - where most people start. Cheap and flexible, but limited horsepower, and it looks like a Pi if someone finds it.
• Hak5 LAN Turtle - tiny and convenient for a fast drop, but modest resources.
• Mini PCs like the GMKtec NucBox G5 - now my favourite primary implant and launching pad (more below).
• A custom circuit board implant - built in-house, small enough to hide inside a keyboards, that exfiltrates keystrokes over an IoT SIM. More on why that one matters shortly.

The One implant you might not ever Find: The Keyboard Implant

Can you spot a 4th implant in the first image? Its there hiding in plain sight.

It’s an ordinary keyboard. It looks normal, types normally, feels normal. But tucked inside is a tiny implant that quietly records everything typed on it - passwords, messages, that “just this once” admin credential someone pastes in and forgets - and ships it back to us over its own cellular connection.

That last detail is what makes it nasty. It never touches the target network. No rogue device hanging off a switch port, no strange MAC to notice, no traffic crossing the firewall for anyone to catch. You could rebuild the computer it’s plugged into from bare metal and the implant wouldn’t blink - it was never on the machine, it was in the keyboard. This is proper espionage-grade kit, hiding in the most boring object on the desk.

And that’s exactly why it belongs in a conversation about the supply chain.

Why the GMKtec Is my favourite Workhorse

The NucBox G5 hits a sweet spot that’s hard to beat for this job. It’s an Intel N97 (Alder Lake) mini PC with 12GB DDR5, an M.2 SATA SSD, gigabit ethernet, dual 4K HDMI, and TPM 2.0 - all in a chassis that fits in your palm, at a budget price.

For an implant that matters:

• It’s a real computer, not a relay. With that N97 and 12GB of RAM it runs Kali Linux as a full launching pad - Responder, scanning, proxying, C2 - all executed locally on the box rather than tunnelled awkwardly back to us.
• Dual uplink by design. The internal ethernet port does the engagement; a separate cellular uplink carries our command-and-control. Our traffic never has to touch the client’s internet egress or their monitoring.
• Interfaces for days. Gigabit ethernet for the wired drop, onboard Wi-Fi for pivoting onto wireless networks or standing up a rogue access point, and Bluetooth for reaching nearby devices all on top of the cellular uplink. One little box carries every radio we’re likely to need, so we can move between wired, wireless and out-of-band without ever swapping hardware.
• It blends in. Gigabit NIC, unremarkable black box - it looks like any other bit of IT tat behind a desk or in a cabinet.
• TPM 2.0 = an encrypted brick if seized. We run full-disk encryption sealed to the TPM and the secure boot state. If someone finds the implant and pulls the drive, there’s nothing to recover - and tampering with the boot chain breaks the unlock automatically. No client data, no tooling, no engagement notes walking out the door.
• Cheap enough to leave behind. When a device costs this little, you can plan around not getting it back.

The Supply Chain Angle - and Why You Should Care

Here’s the part that should keep defenders up at night. If a professional team can do all of this under contract and with a scope, a real adversary can do it for real keeps. And they don’t always need to get into your building - they just need to get a device into your supply chain.

A “vendor” laptop, a server motherboard, a conference freebie, a replacement keyboard with something extra soldered inside. That last one is exactly why we built our USB keylogger implant: to prove that a trusted peripheral, sitting right under someone’s hands, can quietly betray them. Supply chain attacks are not a thought experiment - they are real, repeatable, and cheap.

What Defenders Should Actually Do

• Deploy 802.1X / NAC with proper device authentication. MAC allow-listing alone is trivially spoofed - don’t rely on it.
• Alert on new and unknown devices. Unexpected MACs, unexpected switch-port activity, devices that don’t match an asset - someone should see these.
• Segment the network so a single foothold isn’t game over.
• Tighten physical security. Escort visitors, lock unused ports, secure comms cabinets, and actually challenge people who “look like they’re meant to be there.”
• Treat peripherals and gifted hardware as untrusted. Buy from known channels and inspect what plugs into your estate.
• Run physical red team assessments. It’s the only honest way to find out whether any of the above holds up against someone who’s trying.

A network implant is small, quiet, and patient. The good news is that every one of the controls it tests is one you can get right before someone with worse intentions walks in.

Engagements described here are authorised, scoped, and conducted under contract. Don’t deploy implants on networks you don’t own or have explicit written permission to test.

This tool isn’t just about taking a picture; it’s about extracting deep insights by combining web capture, Optical Character Recognition (OCR), advanced image captioning, and Large Language Model (LLM) powered security analysis.

Unveiling the Web Screenshot Analysis Tool: A Dive into AI-Powered Web Intelligence

What Can It Do? Core Features at a Glance

The Web Screenshot Analysis Tool offers a comprehensive pipeline for web content examination:

• Intelligent Web Screenshotting: Goes beyond simple screen grabs by attempting to remove common ad elements before capturing a full-page screenshot, providing a cleaner view of the core content.
• OCR Text Extraction: Employs Tesseract OCR to pull out all visible text from the captured screenshot, making textual content machine-readable.
• AI-Powered Image Captioning: Leverages BLIP (Bootstrapping Language-Image Pre-training) models (including various sizes like Base, Large, and BLIP-2 variants) to generate descriptive captions for the screenshot, offering a concise summary of the visual content.
• Contextual Security Analysis: This is where the LLM magic comes in. The extracted text and generated image caption are fed to a powerful Large Language Model (with support for various OpenAI models like GPT-3.5-turbo, GPT-4, and newer GPT-4o variants). The LLM is prompted to analyze the content through the lens of the MITRE ATT&CK framework, identifying potential security implications, tactics, techniques, and tools that might be relevant.
• Web-Based User Interface: Provides an intuitive web UI for users to input a URL, select their preferred AI models, and view analysis progress and results in real-time.
• Modular Architecture: Designed with a modular backend (FastAPI) and frontend, supporting both web-based interaction and direct CLI usage for more programmatic access.
• Centralized Configuration: Utilizes pydantic-settings for easy configuration via environment variables or a .env file.

Peeking Under the Hood: Key Concepts and Technologies

This project stands on the shoulders of several fascinating AI and web technologies:

1. Playwright for Web Interaction

The first step is always capturing the webpage. Playwright is used for robust, headless browser automation. It navigates to the target URL, handles page loading intricacies, and captures a full-page screenshot. A key feature here is the attempt to identify and remove common ad selectors (like <iframe> tags or elements with classes like .ad, .adsbygoogle) before the screenshot is taken. This helps in focusing the subsequent analysis on the primary content of the page rather than peripheral advertisements.

2. Tesseract OCR for Text Recognition

Once an image is captured, Tesseract OCR comes into play. It processes the screenshot image and extracts any embedded text. This is crucial because much of the valuable information on a webpage is textual, even if presented within images or complex layouts.

3. BLIP Models for Image Understanding

Understanding the visual context of a webpage is as important as its text. For this, the tool integrates BLIP (Bootstrapping Language-Image Pre-training) models from Hugging Face Transformers. These models are capable of generating descriptive captions for images. For instance, given a screenshot, BLIP might generate a caption like “A news article page discussing cybersecurity vulnerabilities” or “A software repository page on GitHub.” This caption provides a high-level summary that complements the extracted OCR text. The tool supports various BLIP model sizes, allowing a trade-off between speed and caption detail.

4. LLMs and the MITRE ATT&CK Framework for Security Insights

The extracted OCR text and the BLIP-generated image caption are then combined to form a rich contextual input for a Large Language Model. The LLM is prompted with a specific system message, asking it to act as a cybersecurity analyst and to map any findings to the MITRE ATT&CK framework. This framework is a globally-accessible knowledge base of adversary tactics and techniques based on real-world observations. The LLM’s task is to identify: * Potential Tactics (the adversary’s technical goals, e.g., Initial Access, Execution). * Relevant Techniques (how those goals are achieved, e.g., Phishing, Command and Scripting Interpreter). * Mention of Tools or software that could be used in attacks.

The output is structured JSON, making it easy to parse and display, providing a preliminary security-oriented perspective on the webpage’s content.

5. FastAPI and WebSockets for a Reactive Experience

The backend is built with FastAPI, chosen for its high performance and ease of use in building APIs. For real-time progress updates during the multi-stage analysis pipeline (screenshotting, OCR, captioning, LLM analysis), WebSockets are used to communicate from the backend to the frontend, keeping the user informed.

Architecture Overview

The system is broadly divided into:

• Frontend: A simple HTML, CSS, and JavaScript interface (frontend/templates/index.html, frontend/static/css/matrix-theme.css, frontend/static/js/main.js) allowing users to submit URLs and view results.
• Backend API (backend/api/routes.py): FastAPI endpoints to handle analysis requests (/api/analyze) and provide status updates (/api/status/latest), plus a WebSocket endpoint (/api/ws).
• Core Pipeline (backend/core/pipeline.py): Manages the sequence of analysis tasks, orchestrating the different processing components.
• Analysis Components (web_screenshot_pipeline.py): Contains the individual classes responsible for Playwright interaction, OCR processing (Tesseract), BLIP captioning, MITRE ATT&CK prompt generation, and LLM interaction (OpenAI).
• Configuration (config.py): Centralized settings management using pydantic-settings.

Introduction to Password Spraying and Its Relevance to Red Teaming

Understanding Password Spraying Attacks

Password spraying is a brute-force attack technique where an attacker attempts to authenticate multiple accounts using a single password or a small set of passwords. This approach is designed to bypass account lockout mechanisms, which are typically triggered after multiple failed login attempts for a single account. By spreading the attempts across numerous accounts, attackers minimize the risk of detection and account lockouts.

In the context of red teaming, password spraying is a crucial tactic for simulating real-world attacks against organizations. It allows red teamers to test the resilience of authentication systems, identify weak credentials, and assess the effectiveness of monitoring and detection mechanisms.

Password spraying is particularly effective against online services such as Microsoft Office 365 (O365) and Azure Active Directory (Azure AD), which are widely used by organizations. These services often have publicly accessible authentication endpoints, making them prime targets for attackers.

Key Features of Password Spraying Tools

Password spraying tools are designed to automate the process of testing credentials against authentication endpoints. Some of the key features of these tools include:

1. Username Enumeration: Many tools include functionality to identify valid usernames before initiating the spraying attack. This reduces the number of invalid login attempts and increases the efficiency of the attack.

2. Rate Limiting and Jitter: To avoid detection and account lockouts, password spraying tools often include options to introduce delays between login attempts or randomize the order of attempts.

This ML-based detection analyzes patterns across global tenant activity to identify anomalies indicative of password spraying. Unlike heuristic methods, ML-based detection can adapt to new attack patterns, reducing false positives. However, detection delays can range from a few hours to several days, as noted in Microsoft’s documentation. This delay underscores the importance of complementary real-time monitoring.

Sign-In Logs and Error Codes

Sign-in logs in Microsoft Entra ID provide critical insights into failed login attempts. Specific error codes, such as AADSTS50053 (account locked) and AADSTS50126 (invalid password), can indicate password spraying attempts. Organizations can configure Azure Monitor alerts to notify security teams of suspicious activity. These alerts can trigger automated responses, such as account lockouts or IP bans.

Behavioral Analytics

Behavioral analytics tools, such as Microsoft Defender for Cloud Apps (formerly Cloud App Security), analyze user behavior to detect anomalies. For example, a sudden spike in failed login attempts from a single IP address or geographic location can trigger alerts. Behavioral analytics also consider factors like login times and device types to identify potentially compromised accounts.

Custom Detection Rules in SIEMs

Security Information and Event Management (SIEM) platforms like Microsoft Sentinel allow organizations to create custom detection rules. For instance, KQL queries can be used to identify patterns consistent with password spraying, such as multiple failed login attempts across different accounts within a short timeframe.

Tools like Spray365 often exploit weak passwords that meet basic complexity requirements. User education campaigns should emphasize the importance of unique, complex passwords and the risks associated with password reuse.

Geo-Blocking and Conditional Access

Geo-blocking restricts access from regions where the organization does not operate, reducing the attack surface. Conditional access policies in Microsoft Entra ID can enforce additional authentication requirements for high-risk logins, such as those from unfamiliar devices or locations. These policies can be configured to block access entirely or require MFA.

IP Reputation Services

Integrating IP reputation services can help block known malicious IP addresses. For example, TREVORspray uses proxying to evade detection, but IP reputation services can identify and block such proxies. Combining this with real-time threat intelligence feeds enhances the organization’s ability to respond to emerging threats.

Real-Time Monitoring and Alerting

Integration with Security Platforms

Real-time monitoring tools like Microsoft Defender for Identity can detect password spraying attempts by analyzing authentication traffic. These tools integrate with SIEM platforms to provide centralized visibility and alerting.

Automated Incident Response

Automated workflows can be triggered by alerts to contain and mitigate attacks. For instance, when an alert is generated for multiple failed login attempts, the system can automatically disable the affected accounts, block the source IP, and notify the security team. Tools like SprayCannon and CredMaster are designed to evade detection, making automated responses critical.

User Risk Scoring

User risk scoring in Microsoft Entra ID evaluates the likelihood that an account is compromised based on login behavior and other factors. High-risk accounts can be automatically flagged for additional verification or remediation. This feature complements other detection mechanisms by providing a holistic view of account security.

Advanced Threat Hunting Techniques

Analyzing Authentication Patterns

Threat hunters can analyze authentication patterns to identify anomalies indicative of password spraying. For example, a consistent pattern of failed logins followed by a successful login may indicate a compromised account. Tools like DomainPasswordSpray can provide insights into these patterns.

Correlating Events Across Systems

Correlating events across multiple systems, such as email servers and VPN logs, can reveal coordinated attacks. For instance, a successful login to an email account followed by a VPN login from a different location may indicate lateral movement. SIEM platforms like Microsoft Sentinel facilitate this correlation.

Leveraging Threat Intelligence

Threat intelligence feeds can provide information on known malicious IP addresses, domains, and tools. This information can be used to proactively block threats and enhance detection rules. For example, identifying the use of FireProx in authentication traffic can indicate an ongoing password spraying attack.

Emerging Trends and Future Directions

Comprehensive Research on Red Team Exercises

Introduction

Red Team exercises simulate real-world cyberattacks, enabling organizations to test, measure, and enhance their defenses against sophisticated adversaries. These exercises specifically focus on Initial Access—the phase in which attackers first gain a foothold in the target environment—because of its potential to open the door to lateral movement, privilege escalation, and ultimately data exfiltration or sabotage.

The content in this research consolidates multiple sources detailing modern Red Team tactics, techniques, and procedures (TTPs). This includes insights on phishing, malicious document delivery, browser-in-browser (BitB) attacks, and prevalent tools used to bypass endpoint detection and response (EDR) mechanisms. The overarching goal is to highlight the evolving threat landscape and offer recommendations for both offensive teams (Red Teams) and defenders (Blue Teams).

Importance of Initial Access in Red Team Exercises

• Foundation for Subsequent Phases: Once initial access is achieved, adversaries can engage in lateral movement, credential theft, and stealthy persistence.
• High-Impact Risk: Successful initial access often leads to the compromise of critical systems, making early detection vital.
• Realistic Assessment: Replicating real attacker behaviors around this phase exposes defensive blind spots, guiding security improvements.

Key Trends and Techniques in Initial Access

Phishing and Social Engineering

Phishing remains the most prevalent and successful technique for obtaining initial access. Attackers leverage well-crafted email campaigns, SMS (“smishing”), or instant messaging (“ishing”) to trick users into downloading malicious files or entering credentials on spoofed sites.

• Spear-Phishing Attachments (T1566.001)
  Attackers embed payloads in macro-enabled Office files, PDFs, or .LNK shortcuts, prompting users to enable malicious content.
• Adversary-in-the-Middle (AitM)
  Tools like Evilginx or Modlishka enable interception of session tokens, bypassing multi-factor authentication (MFA).

Malicious Document Delivery and Payload Execution

Malicious documents—especially Microsoft Office files—are a favored vector due to user familiarity. These documents may:

• Contain VBA macros (disabled by default in recent Office versions, but often enabled by unaware users).
• Exploit remote template injection (T1221) to fetch payloads externally.
• Use macro obfuscation tools (e.g., MacroPack, Veil-Evasion) to evade signature-based detection.

Exploitation of Internet-Facing Assets

Attackers frequently target unpatched public-facing web servers, VPNs, or cloud services:

• Exploitation of Public-Facing Applications (T1190): Exploit known vulnerabilities or misconfigurations.
• Gaining footholds via remote code execution on outdated CMS frameworks or unpatched VPN endpoints.

Credential Harvesting

Weak or reused passwords remain a prime entry point:

• Brute Force / Password Spraying: Automated attempts against single sign-on portals or email logins.
• Phishing for Credentials: Capturing username/password combos or session cookies in real time.

Malicious Shortcut Files (.LNK)

Malicious .lnk files can run hidden commands or scripts upon double-click. Recent Red Team engagements highlight:

• ISO + LNK Pairing: Hiding .lnk files inside an ISO image to evade Mark-of-the-Web warnings.
• Endpoint Bypasses: .lnk files can circumvent certain EDR or antivirus tools if not correctly configured.

Browser-in-Browser (BitB) Attacks

BitB attacks simulate legitimate OAuth or Single Sign-On (SSO) login pop-ups within a fake browser window, tricking users into entering credentials:

• Popular Tools:
  • Evilginx (bypassing MFA)
  • Modlishka (reverse proxying login sessions)
  • mr.d0x’s BitB Templates (HTML/CSS pop-up clones)
• Applications: Used extensively in targeted phishing where standard browser-based detection fails.

Advanced Persistent Threat (APT) Simulations

Red Teams often emulate APT groups to simulate nation-state or cybercriminal actors:

• Advanced Techniques: Zero-day exploits, stolen code-signing certificates, and living-off-the-land binaries (e.g., PowerShell, mshta.exe).
• Persistence Methods: Registry run keys, scheduled tasks, or custom implants.

Tools and Frameworks

Phishing Toolkits

• GoPhish: Open-source platform for running phishing simulations at scale.
• Evilginx / Modlishka / Muraena: Adversary-in-the-middle toolkits that capture credentials and tokens in real time.

Command-and-Control (C2) Frameworks

• Cobalt Strike: Commercial suite widely used for beacon deployment and collaboration.
• Sliver: Cross-platform C2 with DNS tunneling, modular payload generation, and low detection rates.
• Metasploit: Versatile open-source framework supporting a range of exploits and payloads.
• Havoc & Nimbo-C2: Emerging frameworks known for advanced evasion and modular design.

Payload Obfuscation and Evasion

• MacroPack, Veil-Evasion, ScareCrow: Craft heavily obfuscated macros or executables.
• Limelighter / SigThief: Steal or forge code-signing certificates to bypass allowlisting or reduce user suspicion.

Infrastructure Setup

• Terraform & Ansible: Automate cloud instance creation for phishing redirectors or load balancers.
• socat / Apache mod_rewrite: Redirect traffic from benign domains to malicious C2 backends.
• Domain Fronting: Conceal malicious C2 channels behind reputable domains (e.g., Cloudflare, Amazon AWS).

Challenges and Defensive Considerations

1. Over-reliance on Endpoint Tools: Many organizations lack robust network-layer defenses (e.g., intrusion prevention systems, web proxies).
2. Insufficient MFA Implementation: MFA fatigue or “prompt bombing” can still trick users. Simple push notifications can be bypassed through AitM phishing.
3. Detection Gaps: Signature-based solutions struggle against heavily obfuscated or custom malware.
4. Weak User Awareness: Lack of employee training increases success rates of phishing and social engineering.

Recommendations

1. Phishing-Resistant MFA: Use hardware tokens (e.g., FIDO2) or biometric-based systems to reduce credential theft.
2. Regular Patch Management: Keep internet-facing systems updated to minimize exploit vectors.
3. Hardened Email Security: Deploy advanced email scanning, attachment sandboxing, and domain-based message authentication/reporting (DMARC).
4. User Training: Conduct frequent awareness sessions and phishing simulations.
5. Proactive Red Team Engagements: Integrate Red Team exercises into continuous security assessments.
6. Threat Intelligence and Collaboration: Share findings between Red and Blue Teams to improve detection logic and incident response.

Conclusion

Red Team exercises focusing on Initial Access techniques—particularly phishing, malicious document delivery, and exploitation of public-facing assets—remain critical for evaluating organizational defenses. As threat actors adopt browser-in-browser attacks, code-signing abuse, and advanced C2 frameworks, defenders must respond by fortifying email gateways, automating detection, and staying current on emerging TTPs. Proactive measures—such as frequent training, robust security testing, and advanced MFA—are essential for ensuring resilience against modern adversaries.

Red Teaming in the Modern Era: Initial Access, Phishing, and Password Spraying Discussion

In today’s ever-evolving cybersecurity landscape, organizations face a constant barrage of threats from highly sophisticated adversaries. To keep pace, red teams—trusted groups of offensive security experts—simulate real-world attacks, exposing weaknesses before malicious actors can exploit them. This blog post examines the latest trends in red team initial access techniques, the evolution of phishing as both an attack vector and a simulation tool, and the emerging tools for password spraying. Drawing from recent reports and open-source intelligence, we’ll create a knowledgebase that details the tactics, techniques, and tools that define modern red teaming.

The Changing Face of Red Team Initial Access

Initial access is the first foothold that an attacker establishes within a target network. Recent studies highlight that adversaries are moving beyond traditional brute force or malware-based methods. Instead, they leverage complex multi-step attack chains that mimic real-world intrusions.

According to recent trends, red teams now routinely exploit vulnerabilities in AI-driven systems, legacy internet-facing applications, and even SaaS environments. For example, attackers are now using artificial intelligence to craft personalized phishing messages or launch prompt injection attacks against integrated AI systems. This approach not only bypasses conventional security measures but also minimizes the technical footprint of the simulated attack.

Moreover, as organizations increasingly rely on cloud services, the exploitation of SaaS credential leaks and misconfigured identity and access management (IAM) systems has become a prominent theme. Red team exercises now often include simulated breaches via compromised Office 365 or Azure accounts, taking advantage of weak or outdated authentication practices.

Phishing Evolution: A Key Initial Access Vector

Phishing has transformed from rudimentary spam emails to sophisticated, multi-channel campaigns that can bypass advanced defenses. Modern phishing techniques now incorporate:

• Adversary-in-the-Middle (AiTM) Attacks: These sophisticated phishing campaigns intercept authentication tokens and session cookies, making multi-factor authentication (MFA) less effective. Tools such as Evilginx2 and Modlishka have been at the forefront of these simulated attacks, allowing red teams to recreate the tactics used by state-sponsored groups .
• QR Code Phishing: With the widespread adoption of mobile devices, attackers have embraced QR codes to deliver malicious links discreetly. Advanced variants even use ASCII-based QR codes to evade detection by traditional email scanners.
• Phishing-as-a-Service (PhaaS): The rise of PhaaS platforms has democratized access to advanced phishing kits. These ready-made tools enable attackers—and red teamers—to launch campaigns that steal MFA tokens and leverage deepfake technology for added credibility .

By integrating these techniques into red team scenarios, organizations can test and refine their defenses against attacks that not only target technological vulnerabilities but also exploit human behavior.

Core Code Tools and Frameworks: A Sample Red Team Arsenal

Red teamers have access to a plethora of code tools and frameworks hosted on platforms like GitHub and GitLab. These resources are continuously updated to reflect the latest adversarial techniques. Among the most notable are:

• Evilginx2 and Modlishka: Reverse proxy frameworks that capture credentials and session tokens, simulating real-world bypasses of MFA protections.
• CredSniper: A Python-based framework that focuses on capturing multi-factor authentication tokens by simulating phishing attacks.
• Gophish: An open-source phishing toolkit that allows the design, execution, and tracking of large-scale phishing campaigns , .

These tools provide red teams with the flexibility to simulate a wide array of scenarios—from broad phishing campaigns to targeted credential harvesting. Moreover, repositories that aggregate these tools, such as awesome-RedTeam-Tools and various proof-of-concept collections, ensure that practitioners are always equipped with the latest offensive capabilities.

Password Spraying: A Silent but Potent Threat

While phishing often captures headlines, password spraying remains one of the stealthiest techniques in an attacker’s playbook. Unlike brute force attacks that target one account at a time, password spraying involves attempting a small set of common passwords across many accounts. This “low and slow” approach is designed to avoid detection and account lockouts.

Recent reports have highlighted several cutting-edge tools for password spraying, including:

• Spray365: Tailored for Office 365 and Azure endpoints, Spray365 uses Microsoft’s Authentication Library (MSAL) to identify and exploit weak conditional access policies. Its two-step process—first generating an execution plan and then executing a stealthy spray—makes it especially effective in modern cloud environments .
• Trident: Designed for multi-cloud operations, Trident increases the IP pool for spraying campaigns, making detection much more challenging. Its support for advanced scheduling aligns with real-world account lockout policies.
• SharpSpray and Spray-AD: These tools focus on Windows domains and Active Directory environments. By leveraging protocols like LDAP and Kerberos, they simulate realistic attacks that generate less noise in the system logs .

Each of these tools addresses a critical need: to uncover weak password policies before an adversary exploits them. By integrating password spraying into red team engagements, organizations can gain insight into both the technical and human factors that contribute to security breaches.

Integrating Techniques for a Holistic Red Team Engagement

Modern red teaming is not about isolated tactics—it’s about weaving together multiple techniques to mimic sophisticated adversaries. Consider an engagement that begins with:

1. Reconnaissance and Initial Access: Utilizing open-source intelligence and automated scanning tools, the red team identifies weak points in the target’s digital perimeter. They may discover exposed cloud services, legacy systems, or misconfigured IAM systems.
2. Phishing and Credential Harvesting: Armed with this intelligence, the team deploys advanced phishing campaigns. Whether it’s through AiTM attacks, QR code phishing, or PhaaS kits, the goal is to harvest credentials and gain an initial foothold.
3. Password Spraying: If phishing fails or as a complementary method, password spraying tools like Spray365 or SharpSpray are used to test the strength of account credentials across the organization.
4. Post-Exploitation: Once access is gained, the team uses red team frameworks to simulate lateral movement, privilege escalation, and data exfiltration, mirroring the tactics of actual threat actors.

By integrating these stages, red team engagements can provide a realistic, end-to-end assessment of an organization’s security posture. This approach not only identifies technical vulnerabilities but also exposes gaps in security awareness, incident response, and policy enforcement.

Conclusion: Preparing for the Future

The convergence of red teaming, advanced phishing techniques, and stealthy password spraying represents the future of offensive security testing. As adversaries become more adept at exploiting both technological and human weaknesses, organizations must adopt a proactive stance. By embracing these advanced tools and techniques, security teams can uncover vulnerabilities before they are exploited by malicious actors.

The knowledgebase presented here—from red team initial access trends to the latest code tools and password spraying platforms—provides a comprehensive view of the modern threat landscape. In doing so, it empowers organizations to build robust, layered defenses that not only protect against known attacks but also prepare them for the emerging tactics of tomorrow’s adversaries.

Stay vigilant, keep testing, and continue evolving your defenses—because in cybersecurity, the battle is never truly won; it’s only paused until the next innovative attack emerges.

The Software

This software stack is chosen for its easy of use, easy setup and general versatility. You could defiantly subvert Windows and go with a full Linux based Virtual Machine system.

Base Operating System - Windows 10 Pro

Windows 10 Pro has a lot of features and is a good base OS for everyday use, plus we will get all our exposure to linux systems via the virtual machines from vulnhub and our primary Kali Linux virtual machine that we will setup within Virtual Box. Try to source a cheap retail OEM license key from a reputable non-mainstream source.

Why Windows 10 Pro specifically? Windows 10 Home edition does not come with Hyper-V support which is required to make virtual machines.

Get a blank 8 Gig USB stick to install the Windows 10 media creation tool on it to download and to to be able to install Windows 10 via a USB stick. The details can be found here: Windows 10 Download

Virtual Machine Software - Virtual Box

What is Virtual Box?

Oracle VM VirtualBox (formerly Sun VirtualBox, Sun xVM VirtualBox and Innotek VirtualBox) is a free and open-source hosted hypervisor for x86 virtualization, developed by Oracle Corporation. Created by Innotek, it was acquired by Sun Microsystems in 2008, which was in turn acquired by Oracle in 2010.

VirtualBox may be installed on Windows, macOS, Linux, Solaris and OpenSolaris. There are also ports to FreeBSD and Genode. It supports the creation and management of guest virtual machines running Windows, Linux, BSD, OS/2, Solaris, Haiku, and OSx86, as well as limited virtualization of macOS guests on Apple hardware. For some guest operating systems, a “Guest Additions” package of device drivers and system applications is available, which typically improves performance, especially that of graphics.

Wikipidia Source Entry

This software will allows us to easily manage our virtual machines that we are going to use for hacking.

Download the latest version of virtual box for windows from here: Virtual Box Download

Follow the default install instructions and you should be fine. We will get into some more specific setup steps a bit later.

Attacking Operating System - Kali Linux

Kali Linux is a Debian-derived Linux distribution designed for digital forensics and penetration testing. It is maintained and funded by Offensive Security. Kali Linux has over 600 preinstalled penetration-testing programs…

Wikipedia Source Entry

Download the Kali Linux VirtualBox 32 or 64bit Image file from this link: Kali Linux VM Image Download

Once you have downloaded the image add it to Virtual Box, there are tons of guides on the internet on how to do this exactly so I’m not going to go into detail here about that simple step. Google Search

I would however recommend you setup the Kali instance with at least 2 or more CPU cores and at least 2048 MB or more of RAM.

Another specific requirement is that you should setup two network adapters on the Kali VM. You should find this in the Kali Linux VM settings under the Network menu.

• 1 Bridged Adapter - This allows you to connect to the internet via your local ethernet port
• 1 Host-only Adapter - This will connect to the network where your victim machines should reside.

Victim Virtual Machine Systems - VulnHub

The aim/goal of VulnHub is:

To provide materials that allows anyone to gain practical ‘hands-on’ experience in digital security, computer software & network administration. So VulnHub was born to cover as many as possible, creating a catalogue of ‘stuff’ that is (legally) ‘breakable, hackable & exploitable’ - allowing you to learn in a safe environment and practise ‘stuff’ out.

About VunlHub Source

This is were we will obtain the majority of our free victim virtual machine system images that you will hack for practice.

Here is a link to a even more detailed guide on setting up a hacking lab: VulnHub - Setting up a local lab

Once you have aquatinted yourself with VulnHub download any virtual machine image that suits your level and needs.

Adding OVE or VMDK Virtual Image files to Virtual box

Todo: detail how to add each type of VM files to virtual box.

General Tips

Here are a few recommend things you do to setup and easy ideal environment.

• Make sure that the victim virtual machine images are set up with a Host-only Adapter to keep the separated from your main network and off the internet.
• Read the details of each VulnHub machine to get specific bits of setup information if needed.
• Install Virtual Box Guest Additions for you Kali Linux instance to allow for extra features such as copy,past via OS systems and to enable dynamic screen re-sizing to name a few features.
• Use the following command within Kali Linux to find the network address of the victim virtual machine - note to specify your network adapters correct name for the host-only adapter network.

# check the names of your network interfaces within kali linux with
ip addr
or
sudo ifconfig

# eth1 is the name of the host-only network interface within kali linux and -l to list items.
sudo apr-scan -I eth1 -l

• Do your internet hacking research via a modern browser on Windows 10.
• Microsoft OneNote is a great tool for taking detailed hacking notes.
• Use CherryTree within Kali Linux to keep victim system specific notes.
• I would recommend assigning 2 cores and at least 1024MB of RAM to each VM for smooth operation.
• Also create a Snap Shot called Fresh of each Victim Virtual Box Image before you start hacking it so that you can revert back to this snap short if you break the VM system.

Good luck and have fun, I hoped this helped a little.

The end result should look similar to this.
