Oracle-owned point-of-sale service suffers from malware attack

MICROS, an Oracle-owned division that's one of the world's top three point-of-sale services, has suffered a security breach. The attack possibly comes at the hands of a Russian crime gang that siphoned out more than $1 billion from banks and retailers in past hacks, security news site KrebsOnSecurity reported Monday.

Oracle representatives have told reporter Brian Krebs that company engineers "detected and addressed malicious code in certain legacy MICROS systems" and that the service has asked all customers to reset their passwords for the MICROS online support site. Anonymous people have told Krebs that Oracle engineers initially thought the breach was limited to a small number of computers in the company's retail division. The engineers later realized the infection affected more than 700 systems.
