alpha_spider is a financially motivated threat actor tracked by Microsoft as DEV-0504 and later renamed Velvet Tempest. The content describes it as a prolific ransomware affiliate that has deployed at least six ransomware-as-a-service payloads since 2020 and specifically identifies it as an affiliate of the ALPHV/BlackCat ransomware operation. Microsoft states that DEV-0504/Velvet Tempest relies on access brokers for initial access, has used compromised credentials and remote sign-in to internet-facing systems, and has deployed BlackCat against organizations including in the energy sector. Reported tradecraft includes hands-on-keyboard intrusions; use of Cobalt Strike Beacon; domain discovery; credential theft with tools such as Mimikatz and Rubeus; lateral movement and payload distribution with PsExec; disabling unprotected antivirus; data exfiltration including use of StealBit; and ransomware deployment. The content also links Velvet Tempest to ClickFix campaigns that led to a hands-on-keyboard intrusion culminating in deployment of the Termite ransomware. Aliases directly supported by the content are alpha_spider, DEV-0504, and Velvet Tempest.
