Bright Security launches STAR Fuzzer for agentic harness generation
Original title: Bright Security Introduces STAR Fuzzer, Agentic Fuzzing That Writes Its Own Harnesses and Proves Every Finding
The vendor says a first research run flagged High or Critical issues in 45% of projects tested.
Bright Security launched STAR Fuzzer, a mode of its STAR platform available at brightsec.com/fuzzer. AI selects security-critical functions and writes harnesses, while an evolutionary engine searches for crashes, memory exhaustion and memory-safety bugs without a running application. The company says the first open-source run found High or Critical issues in 45% of projects, and the first month produced ten published findings in eight projects, including the Crystal standard library, htop and RIOT OS.
Unconfirmed: Finding counts and coverage figures are Bright Security's own claims and are not independently verified.
- Confirmed findings include a byte-exact payload that reproduces the crash.
- Named projects include the Crystal standard library, htop and RIOT OS.
- A libxml2 harness reached about 13,600 regions in a 5-million-execution run, the vendor says.
