Rewterz Threat Alert – Agent Tesla Malware – Active IOCs

Severity

Medium

Analysis Summary

Malspam is being used to target victims in an Agent Tesla campaign. Since its initial appearance in 2014, this has been
deployed in many forms, most notably via phishing attempts. AgentTesla is renowned for stealing data from a variety of
target workstations’ apps, including browsers, FTP clients, and file downloaders. Agent Tesla grabs data from the victim’s
clipboard, logs keystrokes, captures screenshots, and gains access to the victim’s webcam. It has the ability to terminate
running analytic programs and anti-virus applications. In an attempt to disguise its capabilities and activities from
researchers, the malware also runs simple checks to see if it is operating on a virtual machine or in debug mode.
