XBOW is an AI-powered offensive security tool that autonomously finds and exploits vulnerabilities in web applications. It analyzes applications for security flaws, executes various attack techniques including cryptographic attacks, IDOR, and remote code execution, while debugging and refining exploit attempts based on server responses. Having demonstrated the ability to solve 75% of web security benchmarks without human intervention, it can implement custom solutions for complex vulnerabilities, such as writing SHA-256 implementations for hash length extension attacks. Its capabilities include simulating real-world attacks, identifying novel exploits, and providing actionable guidance for remediation. XBOW augments the work of offensive security professionals by handling routine vulnerability detection and exploitation, allowing them to focus on more challenging tasks.
