Tapion Polymorphic Decryptor Generator BETA

Author: Piotr

# Views: 1914

Hi,

So here it comes, the beta version of Tapion, i have detected several bugs they should get fixed in newer release.

The main objective of Tapion is to create unical decryptor for shellcode (data), due to that original structure of shellcode is changed (it is crypted). This avoids shellcode detection by signature scanning.

Main features:
+ decryption key based on generated decryptor
+ decryption based on CPU time (selected randomly)
+ random step of xoring, random step of key increasing
+ random registers usage
+ multiple instruction variants (random usage)
+ garbage engine (coprocessor instructions/normal garbage)
+ block swapping

So here it comes:

binary + launcher with some cool GFX :):

here is the screenshot from client:

best regards,
Piotr Bania
