DragonForce Hackers Abuse Microsoft Teams Relays to Hide Backdoor.Turn C2 Traffic
DragonForce ransomware operators tunnel C2 traffic through Microsoft Teams relay infrastructure using a custom Go RAT called Backdoor.Turn, making malicious communications nearly indistinguishable from legitimate collaboration traffic.
Summary written by editorial AI · Source link below
Threat actors associated with the DragonForce ransomware have been observed using a custom Go-based remote access trojan (RAT) called Backdoor.Turn to conceal command-and-control (C2) traffic inside Microsoft Teams relay infrastructure.
According to findings from Broadcom-owned Symantec and Carbon Black, the backdoor was deployed against a major U.S. services firm. The name of the company was
Editorial Analysis
Abusing trusted SaaS relay infrastructure for C2 defeats domain-reputation and IP-blocklist defences; SOC teams need deep-packet or behavioural analysis of Teams traffic to detect this technique.
Enable enhanced logging on Microsoft Teams traffic, deploy anomaly detection for unusual relay-endpoint connections, and add Backdoor.Turn IOCs from Symantec/Carbon Black to EDR rules.
Ransomware actors are hiding command-and-control traffic inside Microsoft Teams infrastructure, making detection extremely difficult without advanced monitoring.
