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

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

The malware often hides behind fake CAPTCHAs and has been used to commit financial fraud. Microsoft took down 2,300 domains that ran it and updated Defender to identify it.
