Microsoft Threat Intelligence observed the persistent growth and operational sophistication of Lumma Stealer, an info-stealing malware used by multiple financially motivated threat actors to target various industries.

Earlier this month, a coordinated disruption action targeting the Lumma malware-as-a-service (MaaS) information stealer operation seized thousands of domains, part of its infrastructure backbone worldwide.

The Lumma infostealer has become a popular way for hackers to steal sensitive data like banking information and cryptocurrency wallets.
