Reverse
Deconstruct proprietary software, protocols, parsers, and trust boundaries.
Offensive security research · Melbourne, AU
Vulnerability research and exploit development targeting the software people, businesses, and critical systems depend on.
Research practice
We combine manual reverse engineering, purpose-built automation, and exploit engineering to turn subtle implementation flaws into clear, reproducible security impact.
Deconstruct proprietary software, protocols, parsers, and trust boundaries.
Use targeted tooling and manual review to surface high-impact flaws.
Turn primitives into reproducible proof-of-concept exploits and full chains that establish true severity for the vendor.
Coordinate disclosure with the affected vendor through the Zero Day Initiative, or deliver verified findings to the client who commissioned the research on their own products, under written authorisation.
