Trying to make sense of the massive theft of credit card numbers at CardSystems, ‘a leading provider of end-to-end payment processing solutions focused exclusively on meeting the needs of small to mid-sized merchants’, in which information on more than 40 million credit cards may have been stolen.
CardSystems itself has issued only a brief statement on its website (no permalink available) saying it had identified
a potential security incident on Sunday, May 22nd. On Monday, May 23rd, CardSystems contacted the Federal Bureau of Investigation. Subsequently, the VISA and MasterCard Card Associations were notified to alert them of a possible security incident. CardSystems immediately began a remediation process to ensure all systems were secure. Additionally, CardSystems immediately engaged an independent 3rd party to validate systems security.
Notice the careful language: It talks only of ensuring all ‘systems were secure’ — in the security industry this is like checking all the locks work while watching all the horses bolting off down the street. (And don’t the FBI work on Sundays? Why wait a day to let them know?)
Then there’s the question: Why wait almost a month to let us know? A separate story by AP quotes CardSystems as saying that
it was told by the FBI not to release any information to the public. The company says it’s surprised by MasterCard’s decision to go public.
Actually, not so, say the FBI: Another AP story quotes an FBI spokeswoman, Deb McCarley, as denying
that the agency told CardSystems not to disclose the existence of the intrusion. McCarley says the FBI told CardSystems to follow its corporate policies without disclosing details that might compromise the ongoing investigation.
In fact, a MasterCard statement suggests that it was they, not CardSystems, who first identified the breach:
MasterCard International’s team of security experts identified that the breach occurred at Tuscon-based CardSystems Solutions, Inc., a third-party processor of payment card data. Third party processors process transactions on behalf of financial institutions and merchants.
Through the use of MasterCard fraud-fighting tools that proactively monitor for fraud, MasterCard was able to identify the processor that was breached. Working with all parties, including issuing banks, acquiring banks, the processor and law enforcement, MasterCard immediately launched an investigation into the breach, and worked with CardSystems to remediate the security vulnerabilities in the processor’s systems.
In the meantime CardSystems was pretending it was business as usual, including an announcement on June 14 of a move into check processing, and posting job-ads for a ‘Software Quality Assurance Analyst’ to cover, among other things, ‘troubleshooting from operations, production, and outside vendors’ who can work ‘in a very fast-paced, high-visibility organization where priorities often change’. Indeed.
Anyway, the scale of the thing is pretty awesome: Softpedia quotes experts as saying
that this is the worst case of data theft in IT history. “In sheer numbers, this is probably one of the largest data security breaches,” said James Van Dyke, principal analyst at Javelin Strategy & Research in Pleasanton, Calif.
And just how did the theft happen? Details are sketchy, probably because no one yet knows (the MasterCard software which identified the fraud did so by monitoring transactions, not the actual breach. In other words, they observed the stolen goods being peddled, not the actual break-in). According to another AP story, MasterCard has identified CardSystems as being ‘hit by a viruslike computer script that captured customer data for the purpose of fraud’, but hasn’t given any more details. CardSystems itself is not talking:
CardSystems’ chief financial officer, Michael A. Brady, refused to answer questions and referred calls to the company’s chief executive, John M. Perry, and its senior vice president of marketing, Bill N. Reeves. A message left for Perry and Reeves at the company’s Atlanta offices was not returned.
Both Perry and Brady have been with CardSystems a little over a year.
