Summary

FAREIT has been a known malware family since 2011. These information stealers are used to download other malware and have been spotted in both Europe and North America.

New variants of this malware are now using a combination of PDF exploits to execute a PowerShell script to perform its malicious routine.

Brute force attacks are also used by this malware to access password-protected shared files. The spyware component also attempts to steal stored account information in certain installed File Transfer Protocol (FTP) clients or file manager software. It also has the capability to steal stored email credentials and information in certain browsers.
