As botnets continue to evolve, so do the techniques required to detect them. While Transport Layer Security (TLS) encryption is widely adopted for secure communications, botnets leverage TLS to obscure command-and-control (C2) traffic. These malicious actors often have identifiable characteristics embedded within their TLS certificates, opening a potential pathway for advanced detection techniques.
In first-of-its-kind research, Rapid7’s Dr. Stuart Millar, in collaboration with Kumar Shashwat, Francis Hahn and Prof. Xinming Ou, at the University of South Florida, studied the use of AI large language models (LLMs) to detect botnets’ use of TLS encryption by analyzing embedding similarities to weed out botnets within a sea of benign TLS certificates.
