Attackers continue to adapt their tactics as organizations rely more heavily on collaboration platforms. A recently disclosed Microsoft Teams EtherRAT Phishing campaign demonstrates how Microsoft Teams can be abused as a trusted communication channel to impersonate corporate IT support and persuade employees to install remote access software before deploying EtherRAT malware.<\/p>\n
Rather than exploiting a flaw in Microsoft Teams, the attackers reportedly rely on phishing, voice-based social engineering, and legitimate administration tools to gain hands-on access to enterprise endpoints. The campaign illustrates how trusted business workflows can become an effective initial access vector when combined with convincing impersonation.<\/p>\n
For security teams, the incident reinforces an important lesson: protecting collaboration platforms requires more than email filtering. Organizations also need clear support verification procedures, application controls, endpoint visibility, and identity-based access policies.<\/p>\n
