Methodologies for discovering zero-day vulnerabilities in embedded aerospace communications stacks before aircraft deployment.
Heritage aviation protocols like ARINC 429 and CAN bus were designed decades ago without authentication or encryption, assuming physical access was impossible in flight.
EvtolSecurity deploys high-speed hardware fuzzing engines that inject billions of malformed packets, illegal frame lengths, and boundary-value payloads into avionics transceivers, identifying memory buffer overflows before flight certification.
Discovered protocol vulnerabilities are mitigated by deploying inline FPGA micro-firewalls that inspect message grammar at wire speed, dropping illegal commands before they reach vulnerable microcontrollers.
