Report: Cards Stolen From Target Used – at Target

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 […]

Symantec Warns: Worm Can Target Internet of Things

Symantec, the security software firm, is reporting that its researchers have discovered a new, malicious “worm” that is spreading on the Internet and has been adapted to attack embedded devices running the Linux operating system, including many devices that are part of the Internet of Things. Writing on the Symantec research blog, Kaoru Hayashi, a threat analyst within Symantec’s Security Response organization, said that the company had uncovered the worm, dubbed Linux.Darlloz, spreading between more common PC systems. However, an analysis of the program revealed that its creators were thinking big: engineering the worm to be capable of attacking a “range of small, Internet-enabled devices in addition to traditional computers.” Specifically, Symantec’s team found variants of Darlloz for chip architectures common in devices ranging from home routers and set-top boxes to security cameras. The warnings about an “Internet of Things worm” were hypothetical, however. Hayashi said that no attacks against non-PC […]

APT or fANTasy: The Strange Story of BadBIOS

Yesterday over on Veracode’s blog I wrote about the ongoing saga of “BadBIOS” – a piece of malicious software that might be the most sophisticated virus ever written, or a figment of the imagination of Dragos Ruiu, the esteemed security researcher who says he discovered it on systems he owned. The story of BadBIOS reads like something out of science fiction. Ruiu has described it in interviews and blog posts as BIOS-based malware that can back door systems running a variety of operating systems – OS X, Windows and even OpenBSD. But it’s also described as an ephemeral kind of ‘we-don’t-know-what,’ that can’t be isolated or analyzed. One Twitter follower of Ruiu’s suggested designating it a “heisenbug” which he defined as “a software bug that seems to disappear or alter its behavior when one attempts to study it.” That would be funny if this weren’t deadly serious. For, really, one […]
