A Tete-a-Tete with RSA Bots

The expansion and specifically the sophistication of botnets has brought with it an increased use of cryptography for safe-guarding communication channels between bots and their command-and-control instances. Asymmetric encryption (or public-key cryptography) currently poses a major challenge for malware analysts. In this regard, understanding the communication protocol is a critical
