Oracle had their computer systems breached and that lead to the compromise of the MICROS customer service portal.
The MICROS customer service portal system had traffic going to a server owned/operated by Carbanak. MICROS is owned by Oracle’s retail division. According to Brian Krebs’ website, there was 700 systems at Oracle that were infected. The malware planted on Oracle’s systems enabled Carbanak to steal customers’ login credentials.
Over 330,000 MICROS point of sales systems are employed in many retail businesses… to name a few are Starbucks, Sonic, Burger King, IKEA, Helzberg diamonds, MGM resorts, Wyndham, Hilton, Marriott. Here is a graphic on Brian’s site.
More details are still coming as the coverage and capability of the attack are still being investigated.
