May 21 (Reuters) - Microsoft ( MSFT ) said on Wednesday its Digital Crimes Unit (DCU)

filed a legal action against Lumma Stealer last week, after it found nearly 400,000 Windows

computers globally infected by the information-stealing malware in the past two months.

Lumma is capable of stealing data from various browsers and applications, such as

cryptocurrency wallets, and installing other malware, the company said in a blog.

Microsoft's ( MSFT ) DCU helped in the "takedown, suspension, and blocking of malicious domains that

formed the backbone of Lumma's infrastructure," via a court order from the U.S. District Court

of the Northern District of Georgia, the blog said.

The U.S. Department of Justice seized the central command structure for Lumma and disrupted

marketplaces where the tool was sold to cybercriminals.

"The growth and resilience of Lumma Stealer highlight the broader evolution of cybercrime

and underscores the need for layered defenses and industry collaboration to counter threats,"

Microsoft ( MSFT ) said in a separate blog post on the malware.
