Break the code, make it a good deal.

What I do

  • 0day research - auditing closed-source appliances and software for memory-safety, logic, and authentication flaws.
  • Exploit development - turning bugs into reliable proof-of-concepts, from auth bypasses to remote code execution.
  • Hardware & firmware - analysing embedded devices, extracting and reverse-engineering firmware images.
  • Coordinated disclosure - working an issue through to a fix, then publishing the analysis once the patch ships.

Track record

ZeroNvll's published portfolio spans vendors including GFI Software, Cisco, Oracle, Check Point, and the Eclipse Foundation - disclosed CVEs with full analyses in the Research section.

I also operate on public bug bounty programs:
