The web site that first broke the news that data on millions of credit cards was lifted from box retailer Target now reports that those cards are being used to make fraudulent purchases at brick and mortar stores- including at Target itself. Writing on the website Krebsonsecurity.com, Brian Krebs said that so-called “dumps” of stolen card data are flooding underground “carder” web sites where cyber criminals fence stolen card information. Citing an unnamed source at a New England bank, Krebs said that the bank had, with his help, purchased about 20 cards for its customers that were offered for sale on rescator(dot)la, the carder web site, and confirmed that all the stolen cards had been used at Target. Furthermore, the source confirmed to Krebs that some of the stolen cards had already been used to make fraudulent purchases – including at Target and other big box retailers. Only one […]

Target Confirms Massive Breach – 40 million Credit Cards Affected
Black Friday just got a bit more black. Target Corp., one of the U.S.’s leading retail outfits, confirmed in a statement Thursday morning that reports of a massive breach of the company’s payment infrastructure, resulting in the exposure of data on an estimated 40 million credit and debit card accounts. The statement, released on Target’s website, follows media reports on Wednesday citing reports from leading credit card issuers. In it, the company confirmed “it is aware of unauthorized access to payment card data that may have impacted certain guests making credit and debit card purchases in its U.S. stores.” According to statements by Target, the credit card data was stolen between Nov. 27 and Dec. 15, 2013 and includes customer name, credit or debit card number, and the card’s expiration date and the CVV, or three-digit security code. Shoppers at the company’s U.S. stores were affected, but the breach did not affect Target’s Canadian […]
Two Million Passwords Stolen From Facebook, Twitter, ADP
The passwords to access more than two million online accounts have been recovered from a server that is part of the command and control network for the Pony botnet, a large and active network of infected computers, according to a blog post from the security firm Trustwave. The company said that it found a cache of approximately two million compromised accounts, most from popular online services such as Facebook, Yahoo, Google and Twitter. More concerning: the cache also contained tens of thousands of credentials for FTP (File Transfer Protocol) servers, remote desktop and secure shell (SSH) accounts, and a site belonging to ADP, the payments processing firm. Facebook accounts made up the lion’s share of the haul, with 318,121 user credentials discovered – 57% of the total. Yahoo was the next biggest victim, with 59,549, almost 11% of the total. Leading Russian social networking sites vk.com and odnoklassniki.ru were also in […]
BitCoin’s Popularity Is Undermining Promises of Anonymity
The virtual currency Bitcoin has soared in value against the U.S. dollar in recent months, topping out a staggering $913 USD to 1 Bitcoin (or BTC) as of late Tuesday. The currency had many ups and downs since it was launched in January 2009. But its main attraction, all along, has been anonymity. Unlike any other online payment system, Bitcoin transactions – like cash transactions – cannot be traced back to specific individuals. Also like cash, they cannot be reversed. Both those factors give Bitcoin users the confidence that their online purchasing activity – whether computer hardware or contraband will remain private. But a group of researchers at two U.S. universities have released a paper that suggests reports of Bitcoin’s anonymity may (to paraphrase Twain) “be greatly exaggerated.” Specifically: the researchers found that, by culling a variety of open source data using public data from the Bitcoin Peer to Peer network and from […]
The Security Week In Review: Same Breach, Different Day
It’s the end of another week and, as has become a pattern, we’re weighing the impact of another massive data breach: this one at Cupid Media, the owner of a network of dating web sites. According to a report on Krebsonsecurity.com, data on some 40 million Cupid Media customers turned up on the same servers that were found holding data stolen from Adobe Inc., PR Newswire and other victims. To get a handle on the impact of this breach and others like it, I invited Ted Julian, the Chief Marketing Officer of CO3 Systems, to talk about the recent string of embarrassing breaches and how companies go wrong (and sometimes right) in responding to them. Co3 sells a service that helps companies structure their response to data breaches and other adverse incidents. We also took the time to talk about the recent FTC Workshop on security and privacy on The […]
