In October 2014, KrebsOnSecurity examined a novel “replay” attack that sought to exploit implementation weaknesses at U.S. financial institutions that were in the process of transitioning to more secure chip-based credit and debit cards. Today’s post looks at one service offered in the cybercrime underground to help thieves perpetrate this type of fraud.
Lost amid the media firestorm these past few weeks about fraudsters turning to Apple Pay is this stark and rather unsettling reality: Apple Pay makes it possible for cyber thieves to buy high-priced merchandise from brick-and-mortar stores using stolen credit and debit card numbers that were heretofore only useful for online fraud.
For the second time in a year, multiple financial institutions are complaining of fraud on customer credit and debit cards that were all recently used at a string of Marriott properties run by hotel franchise firm White Lodging Services Corporation. White Lodging says it is investigating, but that so far it has found no signs of a new breach.
The Obama administration recently issued an executive order requiring that federal agencies migrate to more secure chip-and-PIN based credit cards for all federal employees that are issued payment cards. The move marks a departure from the far more prevalent “chip-and-signature” standard, an approach that has been overwhelmingly adopted by a majority of U.S. banks that are currently issuing chip-based cards. This post seeks to explore some of the possible reasons for the disparity.
An odd new pattern of credit card fraud emanating from Brazil and targeting U.S. financial institutions could spell costly trouble for banks that are just beginning to issue customers more secure chip-based credit and debit cards.
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.
Nearly a week after this blog first reported signs that Home Depot was battling a major security incident, the company has acknowledged that it suffered a credit and debit card breach dating back to April 2014 involving its U.S. and Canadian stores. Home Depot was quick to assure customers and banks that no debit card PIN data was compromised in the break-in. Nevertheless, multiple financial institutions contacted by this publication are reporting a steep increase over the past few days in fraudulent ATM withdrawals on customer accounts.
In the wake of one data breach after another, millions of Americans each year are offered credit monitoring services that promise to shield them from identity thieves. Although these services can help true victims step out from beneath the shadow of ID theft, the sad truth is that most services offer little in the way of real preventative protection against the fastest-growing crime in America.
First American Bank in Illinois is urging residents and tourists alike to avoid paying for cab rides in Chicago with credit or debit cards, warning that an ongoing data breach seems to be connected with card processing systems used by a large number of taxis in the Windy City.
Last week, Target told reporters at The Wall Street Journal and Reuters that the initial intrusion into its systems was traced back to network credentials that were stolen from a third party vendor. Sources now tell KrebsOnSecurity that the vendor in question was a refrigeration, heating and air conditioning subcontractor that has worked at a number of locations at Target and other top retailers.
