Description

This analysis delves into three distinct stealers: Acrid, ScarletStealer, and Sys01. Acrid is a new stealer found in December, employing the 'Heaven's Gate' technique to bypass security controls. ScarletStealer downloads additional executables and Chrome extensions to facilitate data theft. Sys01, also known as 'Album Stealer' or 'S1deload Stealer,' tricks users into downloading malicious ZIP archives disguised as adult videos, ultimately executing a payload called 'Newb' with backdoor capabilities. The report underscores the persistent threat posed by stealers and the need for robust cybersecurity measures.
