Kaspersky researchers discovered a previously undocumented Windows PowerShell malware dubbed PowerPepper and developed by the hacker-for-hire group DeathStalker.

DeathStalker (previously known as Deceptikons) is a threat actor whose activity goes back to at least 2012 [1, 2] known for using a wide range of malware strains and complex delivery chains, as well as regularly using tactics that help them evade detection.
