Cloudflare participates in global operation to disrupt Lumma Stealer
C loudflare’ s Cloudforce One and Trust and Safety team participated in a co-ordinated disruption effort targeting the Lumma Stealer malware operation.
Lumma Stealer( also known as LummaC2) is part of a broader class of information-stealing malware that poses a serious threat to both individuals and organisations.
By exfiltrating credentials, cryptocurrency wallets, cookies and other sensitive data from infected machines, Lumma facilitates a wide range of downstream criminal activity, including financial fraud, identity theft and enterprise breaches that can lead to ransomware. Disrupting this ecosystem is critical to protecting users, undermining the cybercrime economy and preventing further harm.
Lumma Stealer attempted to abuse numerous service
providers’ infrastructure, including Cloudflare, to support their malware operations. Cloudflare detected Lumma Stealer’ s abuse and participated in a Microsoft-led disruption effort. As part of this effort, Microsoft collaborated with other private industry partners, both those directly impacted and those providing intelligence and technical support, along with the U. S. Department of Justice, Europol’ s European Cybercrime Center( EC3) and Japan’ s Cybercrime Control Center( JC3).
Lumma Stealer is a Malware-as-a- Service offering that allows criminals to rent access to an administrative panel, where they can retrieve stolen data and generate customised builds of the malware payload for distribution to victims worldwide.
Like most other information stealing malware, Lumma Stealer is spread primarily through social engineering campaigns that lure targets into following instructions that result in the download and execution of malware.
