MuddyWater used Microsoft Teams to harvest credentials in a "false‑flag" operation

Colleagues, please note: Rapid7 has linked a MuddyWater campaign that leveraged Microsoft Teams for social‑engineering to steal credentials and bypass MFA.

Key points:
- Masqueraded as Chaos (RaaS), yet displayed indicators of targeted, state‑oriented intrusion.
- Screen‑sharing and remote‑support tools (DWAgent, AnyDesk) used for persistence and data exfiltration; no encryption observed.
- A known certificate tied the operation to MuddyWater.

Why it matters: blending state operations with cybercrime tools complicates attribution and response.

What Teams and remote‑support protections have you implemented?
