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 […]

Ephemeral In-Memory Malware Common At High Value Targets

Computer security has always been a game of Spy vs. Spy, with the bad guys trying to stay one step ahead of the latest tactics and tools used to catch them. And that’s still true today, in an age of so-called “advanced persistent threats.” So what’s the next big thing in advanced malware? How about ghostly, ephemeral malware that never exists outside of memory and disappears whenever the infected system is rebooted?   The security firm Triumfant issued a warning on Monday about what it calls “advanced volatile threats” or AVT. The malware is already a common component in attacks against high value targets, including government agencies and intelligence services John Prisco, Triumfant’s CEO and President told The Security Ledger. The terminology here is a bit tricky – as Prisco admits. Technically, almost every online attack begins in memory, where attackers seek to overwrite the memory space used by a […]

Windows XP Users Six Times More Likely To Be Infected By Malware

Microsoft came out with a new edition of its Security Intelligence Report today, saying that company data shows that Windows XP machines are much more likely to be infected in encounters with malicious software on the Internet. Windows XP machines were six times more likely to be infected than machines running Windows 8, the latest version of Microsoft’s operating system, the company said. The Security Intelligence Report (or SIR) is a unique window into the malicious activity online, given Microsoft’s massive footprint of more than 1 billion systems running versions of the Windows operating system, and the detailed data it collects from them through its automatic update patching- and malware removal features. This is the 15th such report Microsoft has issued.  The company used the latest report to hammer home a message about the need for Windows XP users to move off that system to a newer version of the […]

APT-For-Hire: Symantec Outs Hidden Lynx Hacking Crew

This site and others have been writing about the “Advanced Persistent Threat” problem, which has generally been treated as a euphemism for the government and military of The People’s Republic of China or – in some cases – Russia, Iran, North Korea or other un-friendlies. Firms like Mandiant have taken pains to separate the concept of APT from run of the mill cyber criminal hacking groups whose motivation is profit, rather than the acquisition of information that can be used to advance geopolitical or economic goals. Cyber criminal groups may well use “advanced” in their attack methods and “persistent” in their efforts to compromise victim networks, but they weren’t “APT.” Now Symantec Corp. has put a fly into that ointment: publishing a report that pulls the covers off an APT group dubbed “Hidden Lynx” that it claims is responsible for some of the most sophisticated and large scale hacks of […]

Are Anti-Mule Ops Breaking The Bank Fraud Kill Chain?

Mules are the “last mile” in many online fraud operations: the unwitting dupes, or witting co-conspirators who lend their legitimate bank account (and reputation) to fraudsters who are looking for a way to cash out funds from a compromised account. Mules – often lured with promises of “work-from-home” riches receive fraudulent transactions, then immediately withdraw the funds and wire them to the fraudsters, minus a healthy “commission.”   In recent years, there has been ample coverage in the media of cyber crime and fraud and the role of money mules in scams. (I note Brian Krebs excellent reporting on the mule problem on his blog.)  And yet, the supply of mules seems to be endless. Or is it? According to researchers at the security firm RSA, bank account cash-out attacks are becoming less common online, and a sharp increase in busts on money mules may be the cause. Writing on […]
