Labrador Fuzzer (Powered by Penzzer) is a security testing tool developed by Labrador Labs that combines penetration testing and fuzzing capabilities for product security assessment. The tool performs protocol-aware fuzzing attacks against a range of communication protocols, including Wi-Fi, Bluetooth, CANBUS, IPv4, IPv6, and various file formats. It supports custom communication protocol definitions, which can be created using Python, enabling testing of proprietary or embedded system protocols. Key capabilities include: - Protocol-specific cyber attack simulation tailored to packet formats and embedded systems - CVE-based attack vector support, allowing simulations based on publicly disclosed vulnerabilities for each supported protocol - Detection of unknown (zero-day) vulnerabilities in products under development or with undocumented attack surfaces - Automated security testing for continuous vulnerability detection within development processes The tool is designed to support compliance with several international cybersecurity standards and regulations: - Automotive: UNECE Regulation 155 and ISO 21434 - Defence, aerospace, and marine: International weapons systems cybersecurity risk management standards - IoT security testing Labrador Fuzzer targets use cases in automotive, IoT, defence, aerospace, and marine industries, with a focus on embedded systems and hardware-level protocol security testing.
