The active pursuit of online criminals by authorities serves a valuable purpose, but often it ends up netting lesser fish and doesn't complete the entire equation of what is needed to battle today's slick adversaries.
Researchers at ThreatMetrix Labs have come across a new variant of the peer-to-peer (P2P) version of the notorious Zeus trojan.
According to an amended complaint filed last week in U.S. District Court in Brooklyn, Microsoft has named two defendants in its Zeus civil lawsuit who previously were listed as "John Does." They currently are in prison.

Microsoft Security Essentials (MSE), a free utility for Windows-based computers that offers protection against malware, is catching Google's Chrome browser in its dragnet. A faulty signature update for MSE and Microsoft Forefront erroneously classified the Chrome executable file for Windows as an element of the Zeus trojan, notorious for stealing banking information, resulting in a large number of Chrome users being left without their bookmarks and browser plugins. While Microsoft responded within hours with an updated signature (1.113.672.0), and claimed only 3,000 customers were affected, the traffic on blogs and bulletin boards seemed to indicate the number could be much higher. Microsoft advised users to update MSE with the latest signatures and reinstall Chrome.
Despite fresh guidance and quicker fraud detection, the FBI actively is investigating more than 400 cases of corporate bank account takeovers, an official told federal lawmakers last week. Gordon Snow, the FBI's assistant director of the cyber division, told a House Financial Services subcommittee that these cases, in which criminals initiate unauthorized Automated Clearing House and wire transfers from seized accounts belonging to mostly small and midsize businesses, have resulted in the attempted theft of more than $225 million and actual losses of around $85 million. In his remarks, Snow also discussed risks related to ATM skimming, mobile banking and supply chain compromise.
Microsoft has introduced a "fairly major" update to its Malicious Software Removal Tool to detect and kill infections of the insidious and constantly morphing data-stealing malware family known as Zbot, or Zeus. Since the software giant first added detection for Zeus last October, hundreds of thousands of Windows PCs have been expunged of the threat, prominent in banking and e-commerce fraud. But as Zeus, which recently merged code bases with SpyEye, continues to acquire advanced evasion capabilities, Microsoft has had to fight "sneakiness with sneakiness," according to a blog post on Wednesday. The company introduced the update as part of its monthly security patches, released on Tuesday.

A free copy of the BlackHole exploit kit is available on several file-sharing sites, lowering the cost of entry for budding cybercriminals, experts warned this week.
As if Zeus wasn't already a torment, the insidious banking trojan may become even more prolific now that its source code has been leaked on at least two underground forums, according to researchers at Denmark-based CSIS. Peter Kruse, writing on the company's blog, said the source code for the Zeus toolkit is "freely available for inspection, inspiration or perhaps to be compiled and used in future attacks." He expects the leakage to cause the trojan to become more pervasive. One likely can expect the price to fall too. McAfee researchers in September said the Zeus builder toolkit was going for between $700 and $1,500.
The FBI is probing 20 new cases of U.S. businesses losing millions of dollars to cybercriminals, who then siphoned off the cash to accounts in China.
