microsoft teams phishing

This tag covers discussions about phishing attacks that abuse Microsoft Teams, including voice phishing (vishing) campaigns that use Teams calls to trick victims. Recent content details the Nimbus RAT campaign from April 2026, where attackers used Teams voice phishing combined with Windows Quick Assist, a compromised SharePoint tenant, and cloud-hosted instructions to deliver a Java-based remote access trojan. The attack path relied on trusted collaboration platforms rather than traditional malware delivery, highlighting how enterprise tools like Teams can be weaponized. For Windows administrators, these threads emphasize the need to treat SaaS collaboration platforms as part of the security perimeter and to educate users about social engineering tactics that exploit familiar interfaces.
