ValidCC, a dark web bazaar run by a cybercrime group that for more than six years hacked online merchants and sold stolen payment card data, abruptly closed up shop last week. The proprietors of the popular store said their servers were seized as part of a coordinated law enforcement operation designed to disconnect and confiscate its infrastructure.
Joker’s Stash, by some accounts the largest underground shop for selling stolen credit card and identity data, says it’s closing up shop effective mid-February 2021. The announcement came on the heels of a turbulent year for the major cybercrime store, and just weeks after U.S. and European authorities seized a number of its servers.
One of the digital underground’s most popular stores for peddling stolen credit card information began selling a batch of more than three million new card records this week. KrebsOnSecurity has learned the payment card data was stolen in a two-year-long data breach at more than 100 Dickey’s Barbeque Restaurant locations around the country.
Chip-based credit and debit cards are designed to make it infeasible for skimming devices or malware to clone your card when you pay for something by dipping the chip instead of swiping the stripe. But a recent series of malware attacks on U.S.-based merchants suggest thieves are exploiting weaknesses in how certain financial institutions have implemented the technology to sidestep key chip card security features and effectively create usable, counterfeit cards.
The COVID-19 pandemic has made it harder for banks to trace the source of payment card data stolen from smaller, hacked online merchants. On the plus side, months of quarantine have massively decreased demand for account information that thieves buy and use to create physical counterfeit credit cards. But fraud experts say recent developments suggest both trends are about to change — and likely for the worse.
In many ways, the COVID-19 pandemic has been a boon to cybercriminals: With unprecedented numbers of people working from home and anxious for news about the virus outbreak, it’s hard to imagine a more target-rich environment for phishers, scammers and malware purveyors. In addition, many crooks are finding the outbreak has helped them better market their cybercriminal wares and services. But it’s not all good news: The Coronavirus also has driven up costs and disrupted key supply lines for many cybercriminals.
You may have heard that today’s phone fraudsters like to use use caller ID spoofing services to make their scam calls seem more believable. But you probably didn’t know that your bank may be making it super easy for thieves to impersonate the bank, by giving away information about recent transactions on your account via automated, phone-based customer support systems.
In late December 2019, fuel and convenience store chain Wawa Inc. said a nine-month-long breach of its payment card processing systems may have led to the theft of card data from customers who visited any of its 850 locations nationwide. Now, fraud experts say the first batch of card data stolen from Wawa customers is being sold at one of the underground’s most popular crime shops, which claims to have 30 million records to peddle from a new nationwide breach.
On Nov. 23, one of the cybercrime underground’s largest bazaars for buying and selling stolen payment card data announced the immediate availability of some four million freshly-hacked debit and credit cards. KrebsOnSecurity has learned this latest batch of cards was siphoned from four different compromised restaurant chains that are most prevalent across the midwest and eastern United States.
