Sleep with one eye open: how Librarian Ghouls steal data by night


Librarian Ghouls, also known as “Rare Werewolf” and “Rezet”, is an APT group that targets entities in Russia and the CIS.

The malicious functionality of the campaign described in this article is implemented through command files and PowerShell scripts.
