The Coppell, Texas-based pizza restaurant chain Cicis acknowledged a possible credit card breach at more than 135 locations. At the same time, cybersecurity firm Comodo reported new dangerous malware infected Mac operating systems.
The admission by Cicis comes more than a month after KrebsOnSecurity first broke the news.
In a statement, Cicis said that in early March 2016, the restaurant chain received reports from several of its locations that POS systems were not operating properly.
"The point-of-sale vendor immediately began an investigation to assess the problem and initiated heightened security measures," the company said in a press release. "After malware was found on some point-of-sale systems, the company began a restaurant-by-restaurant review and remediation, and retained a third-party cybersecurity firm, 403 Labs, to perform a forensic analysis."
The forensic firm reported its findings on July 19, 2016, confirming that a malicious software program, introduced by a hacker to the POS system, used by some Cicis locations in Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Maryland, Missouri, Mississippi, North Carolina, Oklahoma, Ohio, South Carolina, Tennessee, Texas, Virginia and Wisconsin. It also reported the elimination of the malware threat.
According to Cicis, "the vast majority of the intrusions began in March of 2016," but the company acknowledged the breach started as early as 2015 at some locations.
Cicis said it continues to monitor and upgrade its systems, stating, "While we believe most of the breaches were remedied within a few weeks of the intrusion, out of an abundance of caution we are not declaring some restaurants as threat-free until they were reviewed by our forensic analyst this month."
The restaurant chain advised customers who used a payment card during that time at an affected restaurant keep an eye out for unauthorized activity.
Meanwhile, the Clifton, N.J.-based Comodo reported the latest malware to hit Mac operating systems is the EasyDoc Converter. Cybersecurity experts discovered this dangerous Mac malware on online websites offering applications and software for the Mac OS.
"If Mac users still believe that their systems cannot get infected then they better get wary now," the blog post warned.
The EasyDoc Converter purports to convert files, however, the malicious EasyDoc Converter does not perform any genuine function. It is a script that contains backdoor malware, designated as Backdoor.MAC.Eleanor.
"This Mac malware allows attackers to gain complete access of the operating system, the webcam, shell execution and the file explorer," Comodo continued.
Cybercriminals employed the tool Platypus to create the malicious app. When the malicious app runs it displays a screen typical to a drag-and-drop file converter, but it lacks any functionality. The malware installs a number of malicious components in the startup of the computer: A Tor Hidden Service, Web Service and a PasteBin Agent.
