Skill UI

This skill guides penetration testers on detecting and exploiting race condition (TOCTOU) flaws in web applications. It details advanced techniques, such as using Burp Suite's Turbo Intruder and single-packet attacks, to bypass rate limits, duplicate transactions (e.g., coupon redemption), or manipulate state-changing operations. Essential for comprehensive security assessments and bug bounty hunting.

A comprehensive methodology and checklist for identifying and exploiting race conditions (TOCTOU) in web applications. It guides users to find timing windows, detect vulnerabilities like double-spend or rate limit bypass, and exploit concurrent request flaws in state-changing business logic. Essential for penetration testing and bug bounty hunting.

A comprehensive methodology for exploiting Time-of-Check / Time-of-Use (TOCTOU) race conditions across diverse system layers. This covers symlink swaps, file-descriptor races, kernel double-fetch vulnerabilities, and advanced window-widening primitives like FUSE slow filesystems and userfaultfd. Essential for security researchers targeting race-based privilege escalation in binaries, kernels, and container orchestrators.

A comprehensive playbook for advanced security testing, focusing on race conditions and TOCTOU (Time-of-check to time-of-use) vulnerabilities in web applications. It guides users to exploit non-atomic, state-changing operations (e.g., coupons, balance deductions, single-use rewards) by sending highly synchronized, parallel requests (including HTTP/2 single-packet attacks). Essential for identifying weaknesses in authorization and transactional integrity.
