Six-year-old keylogger malware called Agent Tesla has been updated again, this time with expanded targeting and improved data exfiltration features.
Researchers warn that the newest iteration of the malware, disclosed on Tuesday, is likely to add to this volume of attacks, as threat actors move to adopt the updated version.
“Threat actors who transition to this version of Agent Tesla gain the capability to target a wider range of stored credentials, including those for web browser, email, VPN and other services,” said Aaron Riley, cyber threat intelligence analyst with Cofense in a Tuesday analysis.

The new version of Agent Tesla includes the ability to target a wider range of stored credentials, such as less popular web browser and email clients.
“This may indicate an increased interest in stolen credentials for a more specialized segment of the market or a particular kind of product or service,” said Riley.
Agent Tesla now includes the ability to scoop up credentials for the Pale Moon web browser, an Open Source, Mozilla-derived web browser available for Microsoft Windows and Linux; and The Bat email client, an email client for the Microsoft Windows operating system, developed by Ritlabs, SRL.
