SEKOIA.IO analysts uncovered a new infostealer advertised by its alleged developer as Stealc since January 2023. We associated to this stealer malware samples of a new infostealer family spread in the wild.

We analysed in depth Stealc stealer and shared the results of our investigation in the FLINT 2023-012 (Stealc: a copycat of Vidar and Raccoon infostealers gaining in popularity - Part 1). SEKOIA.IO will publish a write-up focused on the reverse engineering of Stealc.
