AES-Flipper

This tool automates and facilitates an AES CBC BitFlip attack

Usage:

from AES_flipper import Aesflipper

enc = b'....' # hex

plain = b'username=AAAAAAAAAAAAAAAAAAAAAAA&admin=false&time=1653559752.826'
target = b'username=AAAAAAAAAAAAAAAAAAAAAAA&admin=true&ttime=1653559752.826'

flipper = Aesflipper(
    plain=plain,
    ciphertext=enc,
    add_iv=True,
    debug=True
)
token = flipper.full_flip(target=target)
print(token)

Example :

Features :

• Auto-detect blocs/bytes to flip
• Auto-detect flipped bytes
• Forge Flipped ciphertext
• Alert if a flip is impossible: 2 consecutives blocs
• Specify if The first 16 bytes are the IV
• Specify the encoding of the ciphertext , reflected for the output
