Hackers have breached computer systems at Oracle, which include a customer support portal for companies using MICROS point-of-sale credit card systems.
According to KrebsOnSecurity, Oracle acknowledged it had “detected and addressed malicious code in certain legacy MICROS systems”.
“It said it is asking all MICROS customers to reset their passwords for the MICROS online support portal,” said KrebsOnSecurity.
Oracle’s MICROS point-of-sale systems are used at more than 330,000 cash registers in 180 countries.
In South Africa, MICROS is used by numerous chains, including KFC, Steers, Nando’s, Wimpy, Mugg & Bean, and Woolworths.
It is unclear if South African point-of-sales systems were compromised.
