Nimbus RAT: How Threat Actors Are Abusing Microsoft Teams and Google Drive to Deploy a Java RAT

In April 2026, threat actors deployed Nimbus RAT against a legal industry target using Microsoft Teams voice phishing. The attack began with email bombing (282 emails in 90 minutes), followed by a fake IT helpdesk contact via Teams who convinced the victim to grant Quick Assist remote access. Within 20 minutes, a Java-based RAT was deployed that uses Google Drive and Google Sheets for command-and-control, making network traffic appear benign. Analysis of 1,540 suspicious Teams messages across 172 customer environments over 12 months revealed 65% originated from throwaway onmicrosoft.com tenants with IT-themed names. The malware bundles its own Java runtime, implements two credential theft mechanisms, and allows in-memory second-stage code execution. Post-compromise targeting included Signal Desktop attachments and Outlook mailboxes.

For those people like me, who uses M$ Teams at work:

How do you use Teams from a mobile browser?
Is there a trick to do it without using desktop mode?

Any fdroid app to use?
I really don't wanna install Microsoft teams on my mobile phone, but it's super handy to just message colleagues when being late and so on...

P.S.: I REALLY HATE TEAMS
