We predict that by 2028, AI-powered security testing tools will outnumber human pentesters. This shift represents a fundamental change in how we approach cybersecurity challenges. AI is not just another tool - it's becoming essential for addressing complex security vulnerabilities and staying ahead of sophisticated threats. As organizations face more advanced cyber attacks, AI-enhanced security testing will be crucial for maintaining robust defenses.</p> <p>This work builds upon prior efforts[1] and similarly, we believe that democratizing access to advanced cybersecurity AI tools is vital for the entire security community. That's why we're releasing Cybersecurity AI (<code>CAI</code>) as an open source framework. Our goal is to empower security researchers, ethical hackers, and organizations to build and deploy powerful AI-driven security tools. By making these capabilities openly available, we aim to level the playing field and ensure that cutting-edge security AI technology isn't limited to well-funded private companies or state actors.</p> <p>Bug Bounty programs have become a cornerstone of modern cybersecurity, providing a crucial mechanism for organizations to identify and fix vulnerabilities in their systems before they can be exploited. These programs have proven highly effective at securing both public and private infrastructure, with researchers discovering critical vulnerabilities that might have otherwise gone unnoticed. CAI is specifically designed to enhance these efforts by providing a lightweight, ergonomic framework for building specialized AI agents that can assist in various aspects of Bug Bounty hunting - from initial reconnaissance to vulnerability validation and reporting. Our framework aims to augment human expertise with AI capabilities, helping researchers work more efficiently and thoroughly in their quest to make digital systems more secure.</p>"},{"location":"#ethical-principles-behind-cai","title":"Ethical principles behind CAI","text":"<p>You might be wondering if releasing CAI in-the-wild given its capabilities and security implications is ethical. Our decision to open-source this framework is guided by two core ethical principles:</p> <ol> <li> <p>Democratizing Cybersecurity AI: We believe that advanced cybersecurity AI tools should be accessible to the entire security community, not just well-funded private companies or state actors. By releasing CAI as an open source framework, we aim to empower security researchers, ethical hackers, and organizations to build and deploy powerful AI-driven security tools, leveling the playing field in cybersecurity.</p> </li> <li> <p>Transparency in AI Security Capabilities: Based on our research results, understanding of the technology, and dissection of top technical reports, we argue that current LLM vendors are undermining their cybersecurity capabilities. This is extremely dangerous and misleading. By developing CAI openly, we provide a transparent benchmark of what AI systems can actually do in cybersecurity contexts, enabling more informed decisions about security postures.</p> </li> </ol> <p>CAI is built on the following core principles:</p> <ul> <li>Cybersecurity oriented AI framework: CAI is specifically designed for cybersecurity use cases, aiming at semi- and fully-automating offensive and defensive security tasks.</li> <li>Open source, free for research: CAI is open source and free for research purposes. We aim at democratizing access to AI and Cybersecurity. For professional or commercial use, including on-premise deployments, dedicated technical support and custom extensions reach out to obtain a license.</li> <li>Lightweight: CAI is designed to be fast, and easy to use.</li> <li>Modular and agent-centric design: CAI operates on the basis of agents and agentic patterns, which allows flexibility and scalability. You can easily add the most suitable agents and pattern for your cybersecurity target case.</li> <li>Tool-integration: CAI integrates already built-in tools, and allows the user to integrate their own tools with their own logic easily.</li> <li>Logging and tracing integrated: using <code>phoenix</code>, the open source tracing and logging tool for LLMs. This provides the user with a detailed traceability of the agents and their execution.</li> <li>Multi-Model Support: more than 300 supported and empowered by LiteLLM.

These <code>Patterns</code> specify the organization, coordination, and communication methods among agents, guiding decision-making, task execution, and delegation.</p> <p>An agentic pattern (<code>AP</code>) can be formally defined as a tuple:</p> <p>\\[ AP = (A, H, D, C, E) \\]</p> <p>wherein:</p> <ul> <li>\\(A\\) (Agents): A set of autonomous entities, \\( A = \\{a_1, a_2, ..., a_n\\} \\), each with defined roles, capabilities, and internal states.</li> <li>\\(H\\) (Handoffs): A function \\( H: A \\times T \\to A \\) that governs how tasks \\( T \\) are transferred between agents based on predefined logic (e.g., rules, negotiation, bidding).</li> <li>\\(D\\) (Decision Mechanism): A decision function \\( D: S \\to A \\) where \\( S \\) represents system states, and \\( D \\) determines which agent takes action at any given time.</li> <li>\\(C\\) (Communication Protocol): A messaging function \\( C: A \\times A \\to M \\), where \\( M \\) is a message space, defining how agents share information.</li> <li>\\(E\\) (Execution Model): A function \\( E: A \\times I \\to O \\) where \\( I \\) is the input space and \\( O \\) is the output space, defining how agents perform tasks.</li> </ul> <p>When building <code>Patterns</code>, we generall y classify them among one of the following categories, though others exist:</p> Agentic <code>Pattern</code> categories Description <code>Swarm</code> (Decentralized) Agents share tasks and self-assign responsibilities without a central orchestrator. Handoffs occur dynamically. An example of a peer-to-peer agentic pattern is the <code>CTF Agentic Pattern</code>, which involves a team of agents working together to solve a CTF challenge with dynamic handoffs. <code>Hierarchical</code> A top-level agent (e.g., \"PlannerAgent\") assigns tasks via structured handoffs to specialized sub-agents. Alternatively, the structure of the agents is harcoded into the agentic pattern with pre-defined handoffs. <code>Chain-of-Thought</code> (Sequential Workflow) A structured pipeline where Agent A produces an output, hands it to Agent B for reuse or refinement, and so on. Handoffs follow a linear sequence. An example of a chain-of-thought agentic pattern is the <code>ReasonerAgent</code>, which involves a Reasoning-type LLM that provides context to the main agent to solve a CTF challenge with a linear sequence.[1] <code>Auction-Based</code> (Competitive Allocation) Agents \"bid\" on tasks based on priority, capability, or cost. A decision agent evaluates bids and hands off tasks to the best-fit agent. <code>Recursive</code> A single agent continuously refines its own output, treating itself as both executor and evaluator, with handoffs (internal or external) to itself. An example of a recursive agentic pattern is the <code>CodeAgent</code> (when used as a recursive agent), which continuously refines its own output by executing code and updating its own instructions. <code>Parallelization</code> Multiple agents run in parallel, each handling different subtasks or independent inputs simultaneously. This approach speeds up processing when tasks do not depend on each other. For example, you can launch several agents to analyze different log files or scan multiple IP addresses at the same time, leveraging concurrency to improve efficiency. <p>Moreover in this new version we could orchestrate agents and add decision mechanism in several ways. See Orchestrating multiple agents</p>"},{"location":"cai_architecture/#turns","title":"\ud83d\udd39 Turns","text":"<p>During the agentic flow (conversation), we distinguish between interactions and turns.</p> <ul> <li>Interactions are sequential exchanges between one or multiple agents. Each agent executing its logic corresponds with one interaction. Since an <code>Agent</code> in CAI generally implements the <code>ReACT</code> agent model[3], each interaction consists of 1) a reasoning step via an LLM inference and 2) act by calling zero-to-n <code>Tools</code>. </li> <li>Turns: A turn represents a cycle of one ore more interactions which finishes when the <code>Agent</code> (or <code>Pattern</code>) executing returns <code>None</code>, judging there're no further actions to undertake.</li> </ul> <p>CAI Agents are not related to Assistants in the Assistants API. They are named similarly for convenience, but are otherwise completely unrelated.

You could either interact with the agent and give it more instructions, or let it run to see what it explores next.</p> How do I interact with the agent? Type twice CTRL + C <p></p> <p>If you want to use the HITL mode, you can do it by presssing twice <code>Ctrl + C</code>. This will allow you to interact (prompt) with the agent whenever you want. The agent will not lose the previous context, as it is stored in the <code>history</code> variable, which is passed to it and any agent that is called. This enables any agent to use the previous information and be more accurate and efficient.</p> Can I change the model while CAI is running? /model <p>Use <code>/model</code> to change the model.</p> <p></p> How can I list all the agents available? /agent <p>Use <code>/agent</code> to list all the agents available.</p> <p></p> Where can I list all the environment variables? /env <p>Use <code>/env list</code> to see all catalog variables with current values and index numbers for <code>/env set</code>. Use bare <code>/env</code> for <code>CAI_*</code> / <code>CTF_*</code> values in the current session only.</p> <p>For full documentation tables (defaults, constraints, when each applies), run bare <code>/help</code> and scroll past the quick guide. <code>/help topics</code> lists slash commands by category and how to open <code>/help <topic></code> panels (no env tables). For one variable in depth, use <code>/help var VARIABLE_NAME</code> (e.g. <code>/help var CAI_DEBUG</code>).</p> <p>The same topics are covered on the site in Environment Variables.</p> <p></p> How to know more about the CLI? /help <p>In the CLI headless REPL, type <code>?</code> alone for a compact input shortcuts panel. <code>/?</code> is an alias for <code>/help</code> (full guide and env tables when bare).</p> <p></p> Can I expand CAI capabilities using previous run logs? <p>Absolutely!

Let's assume the target name is: <code>target001</code>.</li> <li>Get the log file path, something like: <code>logs/cai_20250408_111856.jsonl</code></li> <li>Start cai again and select the jsonl file:</li> </ol> <p></p> Can I expand CAI capabilities using scripts or extra information? <p>Currently, CAI supports text based information. You can add any extra information on the target you are facing by copy-pasting it directly into the system or user prompt.</p> <p>How? By adding it to the system (<code>system_master_template.md</code>) or the user prompt (<code>user_master_template.md</code>). You can always directly prompt the path to the model, and it will <code>cat</code> it.</p> How do I run the documentation locally? <p>To view and edit the documentation locally, you can use MkDocs, which is a static site generator for project documentation.</p> <p>Steps:</p> <ol> <li> <p>Install MkDocs and the Material theme: <pre><code>pip install mkdocs mkdocs-material\n</code></pre></p> </li> <li> <p>Serve the documentation locally: <pre><code> python -m mkdocs serve\n</code></pre> This will start a local server (usually at http://127.0.0.1:8000) where you can view the docs in your browser.</p> </li> <li> <p>Build the static site (optional): <pre><code>mkdocs build\n</code></pre> This will generate a <code>site/</code> directory with the static HTML files.</p> </li> </ol> <p>For more details, see the MkDocs documentation.</p> How CAI licence works? <p>CAI\u2019s current license does not restrict usage for research purposes. You are free to use CAI for security assessments (pentests), to develop additional features, and to integrate it into your research activities, as long as you comply with local laws.</p> <p>If you or your organization start benefiting commercially from CAI (e.g., offering pentesting services powered by CAI), then a commercial license will be required to help sustain the project.</p> <p>CAI itself is not a profit-seeking initiative. Our goal is to build a sustainable open-source project.
