Telegram C2 refers to the use of the Telegram messaging application as a Command and Control (C2) channel by cyber attackers. Malware on compromised systems communicates with its operators through Telegram, receiving commands and exfiltrating data. This method exploits the platform’s encrypted messaging and widespread adoption for covert operations. It provides a robust and often difficult-to-detect communication channel for malicious actors.
Context
The utilization of Telegram as a C2 channel is a growing concern in cybersecurity news, particularly for its role in facilitating digital asset theft and ransomware attacks. Discussions center on the challenges of detecting and disrupting these communication links due to Telegram’s encryption and global reach. Future security measures will involve enhanced network traffic analysis and collaborative efforts with messaging platforms to identify and neutralize such illicit uses.
