New SynkLoader malware pushed in Microsoft Teams phishing campaign
-
A newly identified malware family, called SynkLoader, is being distributed through targeted Microsoft Teams phishing campaigns. The attackers use compromised Teams accounts to send messages that trick recipients into downloading a malicious file, which then leads to a fake Windows lock screen.
Once the fake lock screen is presented, the victim is prompted to re-enter their credentials. This capture is used to steal both the user’s password and their Windows login information. The malware operates as a loader, pulling a secondary payload designed for credential theft.
The attack vector relies on social engineering through a trusted collaboration tool, making it particularly dangerous in corporate environments. The malware is not yet widely detected, which underscores the need for caution when receiving unexpected file attachments inside Teams chats.
- Primary function: Loader for credential-stealing payload.
- Delivery method: Phishing message via compromised Microsoft Teams account.
- Target: Windows credentials via a simulated lock screen.
- Recommended mitigation: Verify file requests through a secondary channel (e.g., email or phone) before opening.
- Security teams should monitor for unusual Teams messages with file attachments, particularly those prompting for system authentication.
