About the TAPiON (Polymorphic Decryptor Generator) project
TAPiON engine was developed to avoid code detection (shellcode/whatever). The engine can create unical decryptor, encrypt original data and decrypt it on the fly (while code executes).
Features

  • decryption key based on randomly generated decryptor (attacker breakpoint insertion will cause invalid decryption)
  • decryption based on CPU time (selected randomly) - anti emulator code.
  • RDTSC / coprocessor instructions usage - anit emulator code.
  • random step of block xoring
  • random step of key increasing
  • random registers usage
  • multiple instructions variants
  • block swapping
  • garbage engine (normal instructions / coprocessor instructions)
  • block swapping
  • random decryptor size
  • multiple decryptor layers generation
Sample decryptors
TODO (upcoming in new release)

  • multiple encryption/decryption methods (xlat/add/sub/rol)
  • more instruction variants
  • more antiemulator stuff

曾几何时，有人对我说：装B遭雷劈。我说：去你妈的。于是，这个人又对我说：如果再说脏话，上帝会惩罚你的。我说：我操上帝。结论：彪悍的人生不需要上帝。
