Microsoft, in partnership with the U.S. Department of Justice (DOJ), took a major step in dismantling one of the most prolific cybercrime tools currently in circulation. Microsoft’s Digital Crimes Unit (DCU) collaborated with the DOJ, Europol, and several global cybersecurity firms to disrupt the Lumma Stealer malware network — a malware-as-a-service (MaaS) platform implicated in hundreds of thousands of digital breaches worldwide.
According to Microsoft, Lumma Stealer infected over 394,000 Windows machines between March and mid-May 2025. The malware has been a favored tool amongst cybercriminals for stealing login credentials and sensitive financial information including cryptocurrency wallets. It’s been used for extortion campaigns against schools, hospitals, and infrastructure providers. According to the DOJ website, “the FBI has identified at least 1.7 million instances where LummaC2 was used to steal this type of information.”
With a court order from the U.S. District Court for the Northern Districts of Georgia, Microsoft took down roughly 2,300 malicious domains associated with Lumma’s infrastructure. The DOJ simultaneously took down five critical LummaC2 domains, which acted as command-and-control centers for cybercriminals deploying the malware. These domains now redirect to a government seizure notice.
International assistance came from Europol’s European Cybercrime Centre (EC3) and Japan’s JC3, who coordinated efforts to block regional servers. Cybersecurity firms like Bitsight, Cloudflare, ESET, Lumen, CleanDNS, and GMO Registry assisted in identifying and dismantling web infrastructure.
Lumma, also known as LummaC2, has been operating since 2022, possibly earlier, and makes its info-stealing malware available for sale through encrypted forums and Telegram channels. The malware is designed for ease of use and is often bundled with obfuscation tools to help it bypass antivirus software. Distribution techniques include spear-phishing emails, spoofed brand websites, and malicious online ads known as “malvertising.”
Cybersecurity researchers say Lumma is particularly dangerous because it allows criminals to rapidly scale attacks. Buyers can customize payloads, track stolen data, and even get customer support via a dedicated user panel. Microsoft Threat Intelligence previously linked Lumma to notorious Octo Tempest gang, also known as “Scattered Spider.”
In one phishing campaign earlier this year, hackers were able to spoof Booking.com and used Lumma to harvest financial credentials from unsuspecting victims.
Authorities believe the developer of Lumma goes by the alias “Shamel” and operates out of Russia. In a 2023 interview, Shamel claimed to have 400 active clients and even bragged about branding Lumma with a dove logo and the slogan: “Making money with us is just as easy.”
While the takedown is significant, experts warn that Lumma and tools like it are rarely eradicated for good. Still, Microsoft and the DOJ say these actions severely hinder and disrupt criminal operations by cutting off their infrastructure and revenue streams. Microsoft will use the seized domains as sinkholes to gather intelligence and further protect victims.
This situation highlights the need for international cooperation in cybercrime enforcement. DOJ officials emphasized the value of public-private partnerships, while the FBI noted that court-authorized disruptions remain a critical tool in the government’s cybersecurity playbook.
As Microsoft’s DCU continues its work, this Lumma crackdown sets a strong precedent for what can be accomplished when industry and government specialists collaborate to eliminate threats.
As more of these organizations are uncovered and disrupted, remember to protect yourself by changing your passwords frequently and avoid clicking links from unknown senders.
Did you think hitting delete on your AI chatbot conversation actually makes it disappear? Georgia Tech researchers just proved that's not entirely true. They have built a forensic tool called ORISA that can dig deleted conversations from your phone and even rebuild them into a working chatbot session you can keep talking to.
How can ORISA bring deleted AI conversations back?
Touchscreen laptops have been around for years. You can get them in all sizes and shapes. Just not from Apple. For years, the Cupertino giant has treated the idea of a touchscreen MacBook the way I treat a meeting that could have been an email: with open contempt. However, Wednesday looks like the day the company could finally change its mind.
The latest Apple invite puts the “Pro and Tell” showcase in Los Angeles at 10 a.m. PT (1 p.m. ET) on October 28, 2026. Instead of a regular live-streamed keynote, it is an invitation-only, hands-on event for a handful of press and creators (similar to what the company did for the MacBook Neo earlier this year).
Two residents of Chicago have filed a lawsuit in the US over claims that robots run by Coco Robotics and Serve Robotics captured their facial and hand measurements without consent, bringing renewed attention to the food delivery robots. The cases raise a troubling question: If a robot delivers food to your door, can it also be gathering sensitive information about you?
According to a report by The Associated Press, the proposed class-action lawsuits were filed in Cook County on Oct. 9 and allege violations of Illinois’ Biometric Information Privacy Act. The complaints claim that the robots’ cameras and LiDAR sensors captured information on customers’ faces and hands as they approached the machines to pick up their orders. Both have denied the allegations.
