Open Source Highlights

SussyFinder PHP webshell/malware analysis tool using token parsing, MD5 signature filters, Shannon entropy, Z-scores, and weighted threat scores to uncover backdoors.
SQLScan A quick SQL scanner, dorker, and PHP webshell injector tool with significant community stars. YAPO Yet Another PHP Obfuscator — compressing shellcode and injecting security scanner bypass signatures. eval-logger A native PHP extension designed to intercept and log all payload strings passed to the eval() function, assisting in malware deobfuscation and dynamic analysis. Pload Low-level utility to bypass PHP disable_functions restrictions using LD_PRELOAD to establish secure gsocket shells. Physics_lua Mathematical and physics concepts implemented as Lua code. nasm-tutorial A structured guide and repository covering Netwide Assembler (NASM) for x86/x64 assembly programming, stack mechanics, and interfacing with C.
