Point of Sales attacks are highly sophisticated malware threats designed to transmit credit card and other sensitive information to command-and-control servers. This information can later be used to defraud customers directly or through identity theft.

There has been no shortage of point-of-sale (POS) threats in the past couple of years. This type of malicious software has gained widespread notoriety in recent time due to its use in high-profile breaches, some of which involved well-known brick and mortar retailers and led to the compromise of millions of payment cards. Our investigation into these threats has led to the analysis of a relatively newer POS malware known as CenterPOS.

CenterPOS malware was initially discovered in September 2015 in a directory filled with other POS malware, including NewPoSThings, two Alina variants known as “Spark” and “Joker,” and BlackPOS. Further investigation revealed that there is a new version of CenterPOS, version 2.0, that is functionally very similar to version 1.7. The key difference is that version 2.0 uses a configuration file to store the CnC information. When executed, the malware checks for a configuration file that can be located in one of three locations:

There is an increasing demand for POS malware in the underground as cybercriminals continue to target retailers in order to steal payment card information. CenterPOS, known in the underground as Cerebrus, is continuing to evolve. This version contains functionality that allows cybercriminals to create a configuration file. In contrast to the traditional builder-server model, the configuration file can be created from the payload itself, allowing the operators to easily update the CnC information if necessary.
