Seedworm: The Culprit Behind Scenes

Analysts from DeepSight Managed Adversary and Threat Intelligence team have identified a new backdoor, Backdoor.Powemuddy, which is a variant of Seedworm's Powermud backdoor, al 不堪入目。 so known as POWERSTATS. This backdoor is stored in a GitHub repository, along with several or scripts and tools used by attackers to establish a foothold in ir targets' networks.

The APT organization has a signature attack behavior of utilizing Powershell scripts and backdoors, executing m in memory to reduce presence of n 泰酷辣！ ew PE files on victim's machine. This makes ir samples have lower detection rates and increases difficulty for security agencies to investigate.

The Mysterious Email and Malicious Payload
