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

X plays up blue checkmark disclaimer to stave off possible EU fine, source says

REUTERS/Dado Ruvic/Illustration/File Photo BRUSSELS (Reuters) -Elon Musk's social media company X has highlighted a disclaimer to its blue checkmark in an attempt to head off a possible hefty fine from EU antitrust regulators, a person familiar with the matter said. The European Commission in July last year charged X with deceiving users, saying that the blue checkmark does not correspond to industry practices and that anyone can pay to get a "verified" status. The blue checkmark had previously indicated that an account belonged to a public figure whose identity was verified but Musk changed it to indicate it belonged to a paid subscriber after acquiring X in 2022. X has not admitted wrongdoing and the prominent display of the blue checkmark disclaimer is not part of any settlement proposal with the EU tech enforcer, the person said. The prominent display started a week ago. The Commission said it took note of X's announcement. "Our investigation related to the blue checkmark is ongoing," a spokesperson said. X did not immediately respond to an emailed request for comment. The EU probe is under the Digital Services Act which requires large online platforms to do more to tackle illegal and harmful content or risk fines as much as 6% of their global annual revenue. Bloomberg was the first to report on the blue checkmark disclaimer. (Reporting by Foo Yun Chee; editing by David Evans)

Contraceptives for poorest countries stuck in warehouses after US aid cuts
LONDON: Contraceptives that could help prevent millions of unwanted pregnancies in some of the world's poorest countries are stuck in warehouses because of U.S. aid cuts and could be destroyed, two aid industry sources and one former government official said. The stock, held in Belgium and Dubai, includes condoms, contraceptive implants, pills and intrauterine devices, together worth around $11 million, the sources told Reuters. It has been stalled since the Trump administration started cutting foreign aid as part of its 'America First' policy in February, as the U.S. government no longer wants to donate the contraceptives or pay the costs for delivery, they said. The U.S. Agency for International Development (USAID) has instead asked the contractor managing its health supply chain, Chemonics, to try to sell it, two of the sources said. An internal USAID memo, sent in April, said a quantity of contraceptives was being kept in warehouses and they should be 'immediately transferred to another entity to prevent waste or additional costs'. A senior U.S. State Department official told Reuters no decision had been made about the future of the contraceptives. They did not respond to questions about the reasons why the contraceptives were in storage or the impact of the U.S. aid cuts and delays. A spokesperson for Chemonics said they were unable to comment on USAID's plans, but added that the company is working with clients to deliver life-saving aid globally and would continue to support the U.S. government's global health supply chain priorities. The stock represents just under 20% of the supply of contraceptives bought annually by the U.S. for donation overseas, a former USAID official told Reuters. Selling or donating the contraceptives has been challenging, according to the former USAID official, although talks are ongoing. Another option on the table is destroying it, at a cost of several hundred thousand dollars. As time goes on, shelf-lives will also become an issue, one of the sources said. The sources told Reuters that one of the key delays is a lack of response from the U.S. government about what should be done with the stock. It had been destined largely for vulnerable women in sub-Saharan Africa, including young girls who face higher health risks from early pregnancy as well as those fleeing conflict or who otherwise could not afford or access the contraceptives, the sources added. The condoms also help stop the spread of HIV, the former USAID official said. 'We cannot dwell on an issue for too long; when urgency and clarity don't align, we have to move on,' said Karen Hong, chief of UNFPA's supply chain. She said the agency is now working on Plan B to help fill critical supply gaps.
