MODBEACON RAT Leverages gRPC Streaming for Encrypted C2 Communications
A new remote access trojan named MODBEACON uses gRPC streaming technology to encrypt its command-and-control (C2) traffic, making detection more challenging. This approach allows attackers to maintain covert communication with infected systems, highlighting an evolving tactic in cybercrime. Security researchers warn that this technique could be adopted by other malware strains.
