A coordinated global effort by tech companies and law enforcement authorities has resulted in the disruption of a major infostealer malware operation, Lumma. Over 2,300 domains have been seized as part of the crackdown, which aims to cut off the malware's ability to steal sensitive data from web browsers and applications.
Microsoft successfully seized over 2,300 domains used by the Lumma malware operation. The Lumma malware was a major threat to individuals and organizations, stealing sensitive data from web browsers and applications. The disruption of the Lumma operation denied the malicious actors access to their control panel and internet infrastructure. A joint action by tech companies and law enforcement authorities resulted in significant damage to the malware's plans. The Lumma malware was able to bypass some security measures, highlighting ongoing challenges in keeping up with evolving threats.
Microsoft has taken a significant step in disrupting the Lumma infostealer malware operation, which was found to be infecting thousands of Windows and macOS systems worldwide. As part of a coordinated effort between tech companies and law enforcement authorities, Microsoft successfully seized over 2,300 domains that were being used by the malicious actors to host their infrastructure.
The Lumma malware-as-a-service (MaaS) information stealer operation was identified as a major threat to individuals and organizations alike, with its capabilities allowing cybercriminals to steal sensitive data from web browsers and applications. The malware was found to be distributed through various channels, including GitHub comments, deepfake nude generator sites, and malvertising campaigns.
The disruption of the Lumma malware operation marks a significant victory for those involved in the global crackdown. According to Steven Masada, Assistant General Counsel of Microsoft's Digital Crimes Unit, "Between March 16, 2025, and May 16, 2025, we identified over 394,000 Windows computers globally infected by the Lumma malware. Working with law enforcement and industry partners, we have severed communications between the malicious tool and victims."
This disruption also denied the Lumma operators access to their control panel, marketplace of stolen data, and Internet infrastructure used to facilitate the collection and management of that data. This move imposed operational and financial costs on both the Lumma operators and their customers, forcing them to rebuild their services on alternative infrastructure.
In an effort to disrupt the malware's operations, multiple tech companies were involved in the joint action against Lumma's infrastructure. These included Microsoft, ESET, CleanDNS, Bitsight, Lumen, GMO Registry, and global law firm Orrick. The coordinated efforts resulted in significant damage to the malicious actors' plans.
However, despite the disruption of their operations, the Lumma malware continued to pose a threat to individuals and organizations worldwide. Cloudflare reported that the malware was able to bypass its interstitial warning page, causing the company to take extra steps to block data exfiltration. The malware's ability to evade detection highlights the ongoing challenges faced by cybersecurity professionals in keeping up with the evolving threats.
In an effort to mitigate this risk, Cloudflare added a new feature to its service, known as the Turnstile. This feature was designed to prevent malicious actors from bypassing the interstitial warning page and stealing sensitive data.
The Lumma malware operation serves as a reminder of the importance of cybersecurity awareness and the need for individuals and organizations to take proactive measures to protect themselves against evolving threats. As the threat landscape continues to evolve, it is essential that we remain vigilant and work together to disrupt malicious operations like this one.
