Summary
🤩
RockstarWei C is a lead security engineer and offensive security researcher based in Austin with 15 years of experience specializing in exploit development and red-team tooling. Formerly the lead security researcher for Metasploit at Rapid7, he remains a major open-source contributor to the Metasploit Project and related tooling like Metasploitable3 and metasploit-payloads. His work spans low-level Windows internals and payload development through DevOps-style VM/service configuration, demonstrating both deep technical craft and operational pragmatism. A core member of the broader exploit community (Corelan, Exploit-DB) who publishes under the handle sinn3r, he balances automated fuzzing and crash management contributions with hands-on exploit fixes and payload features. Notably, his contributions include building vulnerable VM environments for testing and hardening real-world scanner and payload behaviors, making him as comfortable in C-level exploit logic as in scripting and infrastructure.
