Microsoft Dismantses Major Cybercriminal Operation Targeting Lumma Malware

Tech giant Microsoft has taken decisive action against the “Lumma Stealer,” a powerful malware tool that has silently compromised hundreds of thousands of computers worldwide. In a recent blog post, Microsoft revealed that it secured a court order in Georgia, granting its Digital Crimes Unit (DCU) the authority to dismantle Lumma’s digital infrastructure. This enabled the company to remove, block, or suspend nearly 2,300 websites linked to Lumma’s operations, effectively disrupting its activities. Microsoft collaborated with law enforcement agencies across multiple jurisdictions, including the U.S. Department of Justice, Europol’s European Cybercrime Centre, and Japan’s Cybercrime Control Centre. Key servers controlling Lumma’s activity and underground marketplaces where the tool was distributed have also been seized or shut down.
