Microsoft, the Department of Justice and others have thwarted the use of the Lumma Stealer malware that globally has infected nearly 400,000 computers.

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

In a blog post, Microsoft revealed that a federal court in Georgia authorized its digital crimes unit to take down, block, or suspend nearly 2,300 websites essential to Lumma’s operations. The company also worked closely with local and international law enforcement agencies to dismantle the malware’s infrastructure.
