Lumma Stealer takedown by Microsoft disrupted key infrastructure used to control this fast-evolving info-stealing malware.
Microsoft has successfully taken down the infrastructure behind Lumma Stealer, a prominent info-stealing malware sold as Malware-as-a-Service on cybercrime forums. The operation involved seizing the primary domain used for command-and-control, disrupting the malware’s communication channels. Lumma Stealer was used to extract credentials, browser data and crypto wallet information from infected systems. Active since 2022, it evolved rapidly through regular updates and widespread affiliate distribution. The malware was often bundled in cracked software and phishing attachments.
