NimicStack

NimicStack NimicStack es la implementación pura en Nim de la técnica de Call Stack Spoofing para imitar programas legítimos. Todo el proyecto se basa en la PoC compartida por WithSecure Labs Compilación Puedes compilar directamente el código fuente con el siguiente comando: nim c -d=mingw...

pe-sieve

Intro PE-sieve is a tool that helps to detect malware running on the system, as well as to collect the potentially malicious material for further analysis. Recognizes and dumps variety of implants within the scanned process: replaced/injected PEs, shellcodes, hooks, and other in-memory patches...

LazyHook

Overview LazyHook is a stealthy API hooking framework that bypasses Host Intrusion Prevention Systems HIPS through call stack spoofing. By leveraging CPU-level hardware breakpoints and Vectored Exception Handling, it executes arbitrary code as if it originated from trusted, Microsoft-signed...

Shelter

Shelter Shelter is a completely weaponized sleep obfuscation technique that allows to fully encrypt your in-memory payload making an extensive use of ROP. This crate comes with the following characteristics: AES-128 encryption. Whole PE encryption capability. Removal of execution permission durin...
