ransomware
Chaos in Teams vishing
Attackers leveraged Microsoft Teams vishing (voice phishing) calls combined with custom malware and remote access tools to establish footholds for ransomware deployment. The attack chain demonstrates a multi-stage approach that exploits social engineering on a widely-used communication platform to move from initial contact to full system compromise.
Why it matters: Organizations relying on Teams are exposed to vishing-based compromise chains that can lead directly to ransomware; practitioners should enforce call verification procedures, restrict remote access tool installation, and train users to recognize Teams-based social engineering attempts.
