SCULLY SPIDER

Also known asSCULLY SPIDER

SCULLY SPIDER is a cybercrime group. CrowdStrike described it as operating a malware-as-a-service model in which the group maintains command-and-control infrastructure and sells access to its malware and infrastructure to affiliates, who then distribute their own malware. Public reporting cited here also lists SCULLY SPIDER among eCrime relationships. A Five Eyes joint advisory on Russian state-sponsored and criminal cyber threats to critical infrastructure identified SCULLY SPIDER as one of several Russian-aligned cybercrime groups that pose a threat to critical infrastructure organizations, alongside groups including The CoomingProject, Killnet, Mummy Spider, Salty Spider, Smokey Spider, Wizard Spider, and The Xaknet Team. The content does not provide additional high-confidence detail on specific victim sectors, malware families, or sub-groups beyond that characterization.
