Banks in Azerbaijan that have courted the shadowy trade in spam-advertised pharmaceuticals now have cornered the market for processing credit card payments for fake antivirus software, new data reveals.

In June, KrebsOnSecurity highlighted research from the University of California, San Diego (UCSD) showing that Azerigazbank, a financial institution in Azerbaijan, was the primary merchant bank for most major online-fraud pharmacy affiliate programs. By the time that research was published, those programs had moved their business to another bank in Azerbaijan, JSCB Bank Standard.

ZeuS Trojan for Google Android Spotted

Criminals have developed a component of the ZeuS Trojan designed to run on Google Android phones. The new strain of malware comes as security experts are warning about the threat from mobile malware that may use tainted ads and drive-by downloads.

Researchers at Fortinet said the malicious file is a new version of “Zitmo,” a family of mobile malware first spotted last year that stands for “ZeuS in the mobile.” The Zitmo variant, disguised as a security application, is designed to intercept the one-time passcodes that banks send to mobile users as an added security feature. It masquerades as a component of Rapport, a banking activation application from Trusteer. Once installed, the malware lies in wait for incoming text messages, and forwards them to a remote Web server.

Which Banks Are Enabling Fake AV Scams?

Fake antivirus scams and rogue Internet pharmacies relentlessly seek customers who are willing to trade their credit card numbers for a remedy. Banks and financial institutions become partners in crime when they process payments to fraudsters.

Published research has shown that rogue Internet pharmacies and spam would be much less prevalent and profitable if a few top U.S. financial institutions stopped processing payments for dodgy overseas banks. This is also true for fake antivirus scams, which use misleading security alerts to frighten people into purchasing worthless security software.

Spotting Web-Based Email Attacks

Google warned on Wednesday that hackers were launching targeted phishing attacks against hundreds of Gmail account users, including senior U.S. government officials, Chinese political activists, military personnel and journalists. That story, as related in a blog post on the Official Google Blog, was retold in hundreds of media outlets today as the latest example of Chinese cyber espionage: The lead story in the print edition of The Wall Street Journal today was, “Google: China Hacked Email.”

The fact that hackers are launching extremely sophisticated email attacks that appear to trace back to China makes for great headlines, but it isn’t exactly news. I’m surprised by how few media outlets took the time to explain the mechanics behind these targeted attacks, because they offer valuable insight into why people who really ought to know better keep falling for these attacks. I also think a more complete accounting of the attacks may give regular Internet users a better sense of the caliber of scams that are likely to target them somewhere down the road.

Microsoft has fingered a possible author of the late Rustock spam botnet – a self-described software engineer and mathematician who aspired to one day be hired by Google. Microsoft has apparently allocated significant resources to finding the author, but has not been able to locate him.

Rustock remains dead, but Microsoft is still on the hunt for the Rustock author. In its Second Status Report (PDF) filed last week with a district court in Seattle, Microsoft said it inquired with Webmoney about the owner of the account, and confirmed that it was affiliated with a man named Vladimir Alexandrovich Shergin. Microsoft also mentioned another suspect, “Cosma2k,” possibly named Dmitri A. Sergeev, Artem Sergeev, or Sergey Vladomirovich Sergeev. Microsoft said it is continuing its investigation of these names, to determine whether additional contact information can be identified and to which notice and service can be effected.

Something Old is New Again: Mac RATs, CrimePacks, Sunspots & ZeuS Leaks

One of the biggest challenges in information security — and with security reporting in general — is separating what’s new and worth worrying about from seemingly new threats and developments that really are just old threats repackaged or stubborn facts that get rediscovered by a broader audience. This post represents my attempt to apply that sorting process to several security news headlines that readers have been forwarding my way in the past week, and to add a bit more information from my own reporting.

Scammers Swap Google Images for Malware

A picture may be worth a thousand words, but a single tainted digital image may be worth thousands of dollars for computer crooks who are abusing weaknesses in Google’s Image Search service to foist malicious software.

For several weeks, a number of readers have complained that clicking on Google Images search results redirected them to Web pages that pushed rogue anti-virus or “scareware” through misleading security alerts and warnings. On Wednesday, the SANS Internet Storm Center posted a blog entry saying they, too, were receiving reports of Google Image searches leading to fake anti-virus. According to SANS, the attackers have compromised an unknown number of sites with malicious scripts that create garbage Web pages filled with the top search terms from Google Trends. The malicious scripts also fetch images from third-party sites and include them in the junk pages alongside the relevant search terms, so that the automatically generated Web page contains legitimate-looking content.

A new crimeware kit for sale on the criminal underground makes it a simple point-and-click exercise to develop malicious software designed to turn Mac OSX computers into bots. According to the vendor of this kit, it is somewhat interchangeable with existing crimeware kits made to attack Windows-based PCs.
