Cybersecurity researchers have noticed two strains of point-of-sale (POS) malware which might be energetic within the wild and stealing individuals’s bank card info. 

To this point, they’ve stolen greater than $3.Three million price of fee information, however provided that the strains are energetic, that quantity might be even increased by now. 

Cybersecurity researchers Nikolay Shelekhov and Stated Khamchiev from Group-IB found the strains – known as MajikPOS and Treasure Hunter – earlier this yr, after they discovered their command & management (C2) servers. By the server, they had been capable of deduce that the malware operators – whose identities are unknown on the time – stole fee info from tens of hundreds of bank card holders. 

Tens of hundreds of stolen bank cards

Between February 2021 and September 2022, they had been capable of acquire the small print of greater than 167,000 bank cards. The researchers declare this info might be price greater than $3.Three million on the black market. 

Just about all the information stolen belongs to US-based bank card holders. It took the researchers a month to research some 77,000 card dumps from the MajikPOS panel, and a few 90,000 from the Treasure Hunter panel, after which they deduced that 97% of the playing cards from MajikPOS, and 96% from Treasure Hunter, had been issued by US banks. The remainder had been issued by banks all world wide. 

Legislation enforcement has been notified, the researchers added.

To contaminate POS endpoints, menace actors would first scan networks for open, or improperly secured digital community computing (VNC) and distant desktop protocol (RDP) providers. They might entry (or brute-force their manner into) the programs, and set up the malware. After that, the malware would scan the units and exploit them within the second after they learn and retailer bank card information. 

To guard from such assaults companies ought to make certain their POS programs are protected with a robust password, are repeatedly up to date with the latest software program, and are hidden behind firewalls and different cybersecurity options (opens in new tab).
