B&B Theatres, a company that owns and operates the 7th-largest theater chain in America, says it is investigating a breach of its credit card systems. The acknowledgment comes just days after KrebsOnSecurity reached out to the company for comment on reports from financial industry sources who said they suspected the cinema chain has been leaking customer credit card data to cyber thieves for the past two years.
Headquartered in Gladstone, Missouri, B&B Theatres operates approximately 400 screens across 50 locations in seven states, including Arkansas, Arizona, Florida, Kansas, Missouri, Mississippi, Nebraska, Oklahoma and Texas.
In a written statement forwarded by B&B spokesman Paul Farnsworth, the company said B&B Theatres was made aware of a potential breach by a local banking partner in one of its communities.
“Upon being notified we immediately engaged Trustwave, a third party security firm recommended to B&B by partners at major credit card brands, to work with our internal I.T. resources to contain the breach and mitigate any further potential penetration,” the statement reads. “While some malware was identified on B&B systems that dated back to 2015, the investigation completed by Trustwave did not conclude that customer data was at risk on all B&B systems for the entirety of the breach.”
“Trustwave’s investigation has since shown the breach to be contained to the satisfaction of our processing partners as well as the major credit card brands. B&B Theatres values the security of our customer’s data and will continue to implement the latest available technologies to keep our networks & systems secure into the future.”
The credit card companies generally do not tell financial institutions in these alerts which merchants got breached, leaving banks and credit unions to work backwards from those lists of compromised cards to a so-called “common point-of-purchase” (CPP).
In addition to lists of potentially compromised card numbers, the card associations usually include a “window of exposure” — their best estimate of how long the breach lasted. Two financial industry sources said initial reports from the credit card companies said the window of exposure at B&B Theatres was between Sept. 1, 2015 and April 7, 2017.
However, a more recent update to this advisory shared by my sources shows that the window of exposure is currently estimated between April 2015 and April 2017, meaning cyber thieves have likely been siphoning credit and debit card data from B&B Theatres customers for nearly two years undisturbed.
Malicious hackers can steal credit card data from organizations that accept cards by hacking into point-of-sale systems remotely and seeding those systems with malicious software that can copy account data stored on a card’s magnetic stripe. Thieves can then use that data to clone the cards and use the counterfeit cards to buy high-priced merchandise from electronics stores and big box retailers.
The statement from B&B Theatres made no mention of whether their credit card systems were set up to handle transactions from more secure chip-based credit and debit cards, which are far more difficult and expensive for thieves to counterfeit.
Under credit card association rules that went into effect in 2015, merchants that do not have the ability to process transactions from chip-based cards assume full liability for all fraudulent charges on purchases involving chip-enabled cards that were instead merely swiped through a regular mag-stripe reader at the point of purchase.
If there is a silver lining in this breach of a major silver screens operator, perhaps it is this: One source in the financial industry told this author that the breach at B&B persisted for so long that a decent percentage of the cards listed in the alerts his employer received from the credit card companies had been listed as compromised in other major breaches and so had already been canceled and re-issued.
