 [Threat Actor](https://www.misp-galaxy.org/threat-actor) - Known or estimated adversary groups targeting organizations and employees. Adversary groups are regularly confused with their initial operation or campaign. threat-actor-classification meta can be used to clarify the understanding of the threat-actor if also considered as operation, campaign or activity group.

The malware leverages APIs and authentication tokens to access cloud resources for command and control, with GitHub serving as its initial C2 server. CloudSorcerer operates as separate modules depending on the process it's running in, executing from a single executable and utilizing complex inter-process communication through Windows pipes. The actor behind CloudSorcerer shows similarities to the CloudWizard APT in modus operandi, but the unique code and functionality suggest it is a new threat actor inspired by previous techniques.",
