Earlier this month, a coordinated disruption action targeting the Lumma malware-as-a-service (MaaS) information stealer operation seized thousands of domains and part of its infrastructure backbone worldwide.
This effort involved multiple tech companies and law enforcement authorities, resulting in Microsoft's seizure of approximately 2,300 domains after legal action against the malware on May 13, 2025.
