As readers of this blog are well aware, point of sale services will always be a target for criminals. These devices hold money or credit card information, which makes them valuable. However, the stereotypical gun and ski mask criminal disguise have been replaced with a computer. Any company that processes credit card payments needs to make sure it has the right credit card security software.

This week, two Romanian men were sentenced 15 years and seven years apiece in prison by the U.S. District Court for the District of New Hampshire. Adrian-Tiberiu Oprea, 29, and Iulian Dolan, 28 were found guilty of hacking into hundreds of POS computer systems and stealing credit card data. In all, more than 100,000 customers were said to have their card information compromised.

The total number of unauthorized charges made on the card and remediation expenses is estimated to be $17.5 million.

"Oprea, who was the leader of the scheme, and Dolan, who was his trusted aide, first used the Internet to identify U.S.-based vulnerable POS systems," a DOJ press release said. "After identifying a vulnerable system, Oprea and Dolan would gain access and install software programs called keystroke loggers, which recorded all of the data that was keyed into or swiped through the merchants' POS systems, including customers' payment card data."

The scheme used by Oprea is becoming a popular one among the latest version of high-tech criminals. Because of this, merchants need to make sure their credit card processing system is secure and has the right POS software in place.
