Abuse of Cryptography by Malware

In this chapter, we will protect our tunnel with something more solid than a simple XOR, as modern malware is using a well-known ciphering algorithm to protect its traffic in the transit path.

The topics covered in this chapter are as follows:

  • Introduction to encryption algorithms
  • Protecting your tunnel with AES – stream mode
  • Protecting your tunnel with RSA
  • Hybrid encryption key
