ORCL Oracle Corp

By Robert McMillan 

Oracle Corp. is forcing users of its Micros point-of-sale software to reset their passwords after hackers broke into hundreds of the systems.

In a statement addressed to Micros customers, Oracle confirmed that it has "detected and addressed malicious code in certain legacy Micros systems," and said that it was requiring customers to change passwords for all accounts.

Oracle bought Micros Systems Inc., a maker of internet-connected cash registers used by retailers, hotels and restaurants, for $5.3 billion in 2014. The company's software is used at 330,000 customer sites, according to Oracle's website.

Oracle said the hackers didn't compromise its cloud service or the company's corporate network.

Blogger Brian Krebs first reported the breach on Monday, saying that it appeared to be the work of a Russian criminal gang looking to steal payment-card data, and that the gang had already broken into hundreds of systems.
