Breach at Goodwill Vendor Lasted 18 Months

C&K Systems Inc., a third-party payment vendor blamed for a credit and debit card breach at more than 330 Goodwill locations nationwide, disclosed this week that the intrusion lasted more than 18 months and has impacted at least two other organizations.

cksystemsOn July 21, 2014, this site broke the news that multiple banks were reporting indications that Goodwill Industries had suffered an apparent breach that led to the theft of customer credit and debit card data. Goodwill later confirmed that the breach impacted a portion of its stores, but blamed the incident on an unnamed “third-party vendor.”

Last week, KrebsOnSecurity obtained some internal talking points apparently sent by Goodwill to prepare its member organizations to respond to any calls from the news media about the incident. Those talking points identified the breached third-party vendor as C&K Systems, a retail point-of-sale operator based in Murrells Inlet, S.C.

In response to inquiries from this reporter, C&K released a statement acknowledging that it was informed on July 30 by “an independent security analyst” that its “hosted managed services environment may have experienced unauthorized access.” The company says it then hired an independent cyber investigative team and alerted law enforcement about the incident.

C&K says the investigation determined malicious hackers had access to its systems “intermittently” between Feb. 10, 2013 and Aug. 14, 2014, and that the intrusion led to the the installation of “highly specialized point of sale (POS) infostealer.rawpos malware variant that was undetectable by our security software systems until Sept. 5, 2014,” [link added].

Their statement continues:

“This unauthorized access currently is known to have affected only three (3) customers of C&K, including Goodwill Industries International. While many payment cards may have been compromised, the number of these cards of which we are informed have been used fraudulently is currently less than 25.”
