“RustyBuer” is a fresh variant of a malware loader called Buer written in Rust. The malware is said to have affected no fewer than 200 organizations across more than 50 verticals since April. The loader is a modular malware-as-a-service offering that’s sold on underground forums. It’s the latest in a series of efforts aimed at adding an extra layer of opacity, as cybercriminals are paying increased attention to new programming languages in hopes that doing so will enable the attack code to slip past security defenses.
