Saifeldeen Aziz (wr3nchsr) is a vulnerability researcher specializing in low-level security. He got into offensive security through CTF competitions, starting with binary exploitation, and has spent seven years working across reverse engineering, firmware analysis, source code auditing, and exploit development against embedded devices. He has discovered zero-day vulnerabilities in widely deployed products from vendors including PAX Technology, Huawei, ZTE, VMware, and TP-Link, ranging from memory corruption to command injection and privilege escalation. More recently, he has been looking at large, complex software, probing where its trust assumptions break down.
