wrk

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed wrk load-testing guide with a risky but purpose-aligned example for randomized client IP headers that users should only apply in authorized test environments.

Install only if you need wrk load-testing help. Use the randomized X-Forwarded-For examples only on systems you own or are explicitly authorized to test, and avoid using them to bypass rate limits, abuse controls, logging, or attribution on third-party or production services.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Finding

The skill includes detailed instructions and ready-to-run Lua examples for randomizing X-Forwarded-For and X-Real-IP headers, which facilitates IP spoofing behavior and can undermine IP-based logging, rate limiting, abuse detection, and forensic attribution. Although framed as load testing, this goes beyond ordinary benchmarking and meaningfully lowers the barrier to conducting evasive or misleading traffic generation, especially because it explicitly uses public-looking randomized source IPs.
