More than 2000 malicious domains linked to the Lumma infostealer have been suspended and blocked
The infrastructure of the Lumma infostealer has been disrupted following an international law enforcement operation led by the U.S., EU, and Microsoft.
Nearly 2,300 malicious domains linked to the Lumma infostealer have been suspended and blocked by Microsoft, which was also able to dismantle Japan and European infrastructure, while an additional five domains were sequestered by the U.S. government.
FBI senior official Brett Leatherman said that while Lumma could reorganise in the future, such a takedown effort remains valuable in reducing trust in the cybercrime landscape.
"I think these actors should know that when we have the technical capacity to do this, there are operational security concerns within that ecosystem that they should take note of and maybe not trust the operational security of their colleagues in this environment because of technical operations like this," Leatherman added.
Commenting, James Shank, director, threat operations at Expel, said: "In recent years, Europol has tuned their targeting of groups perfectly. This operation today may take out the leader in the infostealer space, Lumma.
“As we've tracked attacks across industries, we've seen Lumma Stealer become the preferred malware to steal credentials. The developers have been effective at making a product easily purchased and leveraged by cybercriminals. The activity against Lumma Stealer is going to be widely felt.”
