It was another eventful week in security, with another big revelation in the story of a hack of box retailer Target Inc. That update – which accompanied Target’s fourth quarter earnings guidance – nearly doubled the number of known victims of that attack. It also revealed that credit card data was not the only information stolen by hackers, who also made off with customer names, mailing addresses and emails. In this latest installment of Security Ledger’s Security Week in Review, we spoke with Jody Brazil, the President of the security firm FireMon about the week’s events. Jody is a seasoned security professional who works day-in-day-out with companies that are trying to manage their risk. He said that even large companies like Target can fall victim to sophisticated attacks, but the IT security may be too quick to give up on traditional defensive technologies. Jody and I had an interesting chat about […]

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 […]
Snowden Borrowed from APT Playbook In NSA Hack
We know for sure that Edward Snowden made short work of the protections that the National Security Agency used to segregate classified data. Snowden’s revelations about government spying on foreign governments, domestic and foreign firms and…well…just about everyone else first appeared in print in May. Since that time, a looming question is “how?” In other words: how did a single contractor gain access to such a massive trove of classified intelligence while working for the most security conscious organization in the world? While the exact methods used by Snowden are still not known, there are many theories. Now the security firm Venafi thinks that it has an answer, and is challenging the NSA to prove it wrong. In a blog post on Wednesday, the company laid much of the blame on poor management of digital certificates and user credentials, which allowed Snowden to move laterally within the NSA’s classified […]
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 […]
Malware Supply Chain Links Eleven Attacks
Fresh off their discovery of a previously unknown (‘zero day’) security hole in Microsoft’s Internet Explorer web browser, researchers at the security firm Fireeye say that they have evidence that a string of sophisticated attacks have a common origin. In a report released on Monday (PDF), the firm said that many seemingly unrelated cyber attacks identified in the last year appear to be part of a “broader offensive fueled by a shared development and logistics infrastructure” — what Fireeye terms a ‘supply chain’ for advanced persistent threat (APT) attacks. At least 11 APT campaigns targeting “a wide swath of industries” in recent months were found to be built on a the same infrastructure of malicious applications and services, including shared malware tools and malicious binaries with the same timestamps and digital certificates. “Taken together, these commonalities point to centralized APT planning and development,” Fireeye wrote. The attacks link at least 11 separate […]
