Breach Update: Forever 21 Stored 5-Year-Old Transaction Data
Written by Evan SchumanNew information released by Forever 21 confirms that the almost 100,000 credit and debit cards accessed from the chain in a breach included transactions from 2003 through 2005, which were stored on a corporate data center, apparently in violation of PCI rules.
"The files were inadvertently retained within other data files and this was not uncovered by the assessor," said a Forever 21 statement issued to StorefrontBacktalk in response to written questions.
Unlike some of Forever 21’s fellow retail chain victims in the so-called TJX Breach case—including TJX, BJ’s Wholesale Club, OfficeMax, Boston Market, Barnes & Noble, Sports Authority and DSW—Forever 21 now says that wardriving (wireless interception) was not involved in its breach and that the data was accessed directly from the corporate data center.
"The numbers were not stolen at the point-of-sale. Stored data was illegally accessed from the corporate data center. The data was taken in January 2008, but the data was related to transactions occurring in years 2003 to 2005," the statement said.
The older data came from a single store in Fresno, Calif., raising the possibility that it was test data that had been used for a system trial and that it had been long forgotten.
Forever 21’s statement also said that neither the chain’s internal security mechanisms nor outside allies (credit card issuers, issuing banks, etc.) identified that the chain had been breached at all.
"The United States Secret Service contacted us in Spring of 2008 indicating that our name was among a list of retail stores which were thought to be potential targets. Neither the monthly vulnerability scan conducted by our outside audit company nor an internal investigation conducted as a result of the contact revealed signs of a breach," the statement said. It wasn’t until Aug. 11—some six days after the feds unsealed the federal charges naming Forever 21 and other retail chains as victims—that "the Secret Service was able to provide us with information that enabled us to confirm a breach."
Cards issued by European banks when used online cross border don't usually support AVS checks. So, when a European card is used with a billing address that's in the US, an ecom merchant wouldn't necessarily know that the shipping zip code doesn't match the billing code.
