KNOCKOUT SPIDER is an eCrime adversary primarily motivated by financial gain, known for its multi-year operations and adaptive tactics. While referred to by CrowdStrike as KNOCKOUT SPIDER, this group is also recognized under the community identifiers Evilnum, DeathStalker, and TA4563. Unlike groups focused solely on ransomware deployment, KNOCKOUT SPIDER, particularly through its DeathStalker persona, engages in cyber-espionage and data theft, offering 'hacking-for-hire' services. The group also utilizes its Evilnum and TA4563 aliases for campaigns involving customized malware to target financial institutions. It is important not to conflate KNOCKOUT SPIDER with other 'Spider' groups like Wizard Spider, which operates with a different primary toolset and targeting profile.
