Rewterz Threat Alert – LinkedIn Phishing Campaign Spreads Agent Tesla

August 26, 2020

Severity

Medium

Analysis Summary

The popular professional networking and job search site, LinkedIn, is currently being used by some threat actors as the lure for a social engineering scheme designed to steal a user’s credentials and spread malicious binaries. The bad actors also used a legitimate site hosting company, called Yola, to host the malicious content in an attempt to further look legitimate. The .NET-based binaries hosted on this site are related to the Agent Tesla malware and another previously unseen in-the-wild malware family. Its major functionality is information stealing and exfiltrating data through SMTP. Agent Tesla has been a frequent occurrence in cyber attack campaigns throughout the second quarter of 2020, and is active again.

Impact
