The Central European nation's Directorate for Fighting Electronic Crime said Monday in a statement that the suspects infiltrated a number of computers to steal credit card data that resulted in losses of about $800,000.
The accused hackers, ages 20 to 32, installed keylogger software onto the computers to steal card data at point-of-sales systems, said Romanian authorities, who worked with the FBI on the investigation.
The arrests came after police last Thursday raided a Bucharest home, where they discovered nine laptop computers, two desktops, five hard drive, in addition to CDs and memory sticks. Authorities also confiscated more that $200,000.
Recently, Romanian cybercriminals have made news. Some 20 international phishers were busted in March for stealing credentials that netted them hundreds of thousands of dollars. And last week, a Romanian man became the first international phisher ever to be sentenced in the United States.
