Microsoft Teams used to spread burgeoning DarkGate malware

The sophisticated DarkGate malware has seen a notable spike in distribution, largely due to a phishing campaign utilising compromised Microsoft Teams accounts. As a part of a ransomware-as-a-service for $100,000 a year, this development is believed to be an attempt by the malware’s developer to grow their affiliate network. The malware was delivered via a zip file posing as a PDF document on Microsoft 365 accounts, exploiting a lack of security features.
