Update: xor-kpa.py Version 0.0.6

Filed under: Encryption,My Software,Update — Didier Stevens @ 0:00

This is an update for my tool to perform XOR known plaintext attacks: xor-kpa.py.

The tool has been updated for Python 3, and 3 new plaintext have been added, all for Cobalt Strike configurations.

cs-key is the header of the configuration entry for the public key.

cs-key-dot is the header of the configuration entry for the public key XORed with value 0x2E (a dot).

cs-key-i is the header of the configuration entry for the public key XORed with value 0x69 (letter i).
