Microsoft said Wednesday that it broke down the Lumma Stealer malware project with the help of law enforcement officials across the globe.

Microsoft and law enforcement have announced a court-authorized takedown of Lumma, a prolific info-stealer malware operation found on more than 394,000 Windows PCs globally, mostly in Brazil, Europe, and the United States.

Lumma malware, a MaaS platform active since 2022, has stolen data from 1.7M+ devices, targeting cryptos, logins, and financial information on Windows systems.
