Job
Description
Role & responsibilities Perform fuzzing of network protocols on devices like routers, Wi-Fi routers, ONT/OLT, firewalls, and other network appliances. Research and develop fuzzing strategies to test network protocols, identify vulnerabilities, and improve security. Work with tools such as Synopsys Defensics, AFL, Peach Fuzzer, or similar for fuzzing network protocols. Collaborate with hardware and firmware teams to understand device functionality and how to target fuzzing effectively. Analyze crash reports and debug logs to identify root causes of vulnerabilities and provide detailed remediation steps. Prepare technical documentation and reports on the findings from fuzzing activities. Stay updated with the latest security trends, techniques, and tools in network protocol fuzzing. Preferred candidate profile Minimum 1 year of experience in fuzzing network protocols or security testing of network devices. Strong understanding of network protocols (e.g.TCP/IP, DHCP, DNS, HTTP, SIP, etc.). Experience with fuzzing tools (e.g., Synopsys, Defensics, AFL, Peach Fuzzer, Sulley, or custom fuzzers). Knowledge of network hardware, embedded systems, and operating systems. Familiarity with router, firewall, Wi-Fi router, ONT/OLT technologies, and associated protocols. Hands-on experience with debuggers, crash analysis, and memory corruption vulnerabilities. Solid understanding of network security concepts and vulnerability assessment techniques. Prior experience with security assessments and penetration testing of network appliances. Familiarity with scripting languages (e.g., Python, Bash) for automation of testing processes. Knowledge of reverse engineering and static/dynamic analysis of firmware. Certifications (Optional but Preferred) : OSCP, CEH, or other relevant security certifications.
