Bright Security launches STAR Fuzzer with AI-generated harnesses

Bright Security released STAR Fuzzer, an agentic fuzzer that picks security-critical functions, writes harnesses with AI and hunts bugs via evolutionary search without a running app. Its first open source run found High or Critical issues in 45% of tested projects, including Crystal, htop and RIOT OS.

• High or Critical issues found in 45% of tested projects
• Ten published findings in eight projects in the first month
• Each finding ships with a byte-exact reproducing payload
• No running application required; AI handles targets and harnesses
