Berlin, Germany
Summary
🤩
RockstarMarc Heuse is a veteran security researcher and Teamlead Software Assurance based in Berlin, with roots in hands-on vulnerability discovery since the early 1990s and a track record of founding the influential research group The Hacker’s Choice. He combines deep technical expertise in network and embedded security—particularly IPv6, automotive systems, and SWIFT transaction analysis—with practical offensive skills from penetration testing, source-code audits, and binary disassembly. As the author and maintainer of widely used tools like THC-Hydra and thc-ipv6, and a contributor to major fuzzing platforms (AFL++, OSS-Fuzz, LibAFL, ClusterFuzz), he bridges research, tooling and production-scale fuzzing infrastructure. His career spans leadership roles at SUSE, enterprise consulting, and independent consulting since 2007, now leading software assurance at Security Research Labs. Notably, he still pursues unconventional targets (cars to banking middleware), reflecting a curiosity-driven approach that yields impactful, widely adopted security tooling.
