While most sane people around the world are enjoying a romantic Valentine’s Day today, we at SophosLabs remain vigilant on the front line of the war against malware. This year, Valentines Day coincides with the Chinese New Year as well as the start of the Winter Olympics in Vancouver, and many malware attacks have centred around SEO poisoning of these and other topical search terms. The Chinese New Year of the Tiger is proving a popular target, especially as this ties in with any Tiger Woods related searches: ...

While everyone is searching the web for the unusual gift on Valentine’s Day, Cybercriminals take this opportunity to propagate Rouge Antivirus. I have searched for the keywords “unusual-valentines-day-gifts”, gives the following results: Clicking the highlighted link above will lead to fake message such as “Alert! Your system is exposed to risk of virus attack. It’s highly recommended to check your PC immediately. Press OK to start the scan right now”. ...

In the past, viruses and computer threats were created simply for the sake of it. Sometimes these threats would wipe your hard drive clean—just to let you know you’d been owned. This is not the case anymore; nowadays most of the threats we see are profit-oriented and try to keep a very low profile so that they aren’t easily detectable by security software. Backdoor.Tidserv does a very good job in that sense, especially with the latest version (TDL3), which uses an advanced rootkit technology to hide its presence on a system by infecting one of the low-level kernel drivers and then covering its tracks. While the rootkit is active there is no easy way to detect the infection, and because it goes so deep into the kernel, most users cannot see anything wrong in the system. ...

(BBC) Lonely internet users are being warned about Fembot, a piece of malicious software that poses as a flirtatious woman looking to chat on instant messaging services. Victims are persuaded to give out personal information that could be used for fraud or identity theft, according to security experts. Fembot was first spotted in 2007 but hasn’t been seen much since then. However, there are signs she may be back on the scene in time for Valentine’s Day. ...

At the ShmooCon hacker conference in Washington, D.C., last week two security researchers showed the very sensitive information that people inadvertently make available over peer-to-peer networks. In their presentation, “Information disclosure via P2P networks: Why stealing an identity via Gnutella is like clubbing baby seals,” pen testers Larry Pesce and Mick Douglas said they found a lot of music, porn, malcode collections and the following: driver’s licenses, passport and tax return forms with Social Security numbers; someone’s will A retirement analysis form with savings account totals and income estimates; An IRS form with taxpayer identification number; A completed Turbo Tax form with personal information filled in. The two have started The Cactus Project to help security specialists do similar research to help organizations tighten up the information they share over P2P. They list best-of-breed tools for conducting the research, including Mutella and the Gnutella Protocol on their site http://pauldotcom.com/cactusproject.html. ...

Peter Coogan at Symantec put up a very interesting blog post yesterday about a crimeware kit called SpyEye v1.0.7 (on sale now on Russian sites — $500) that has a module that will kill a Zeus bot infection on a victim’s computer so the bot created by SpyEye can take it over. In September, Computer Weekly reported the Swedish telco Telia Sonera shut down the Internet connections of Latvian company Real Host after it was linked to the Zeus botnet. At the time, researchers said they believed Real Host’s servers had captured about 3.6 million PCs for the Zeus botnet. ...

At the BlackHat DC conference and SchmooCon, Nicolas Seriot, an independent researcher and Tyler Shields of Veracode have independently presented two very similar papers. The papers analyse weaknesses in security and application delivery models for iPhone and Blackberry and provide interesting read, especially if you are looking to write the next spyware application or a bot for one of the platforms. For me, the most interesting part of the papers is the one that shows that regardless of the implemented security mechanisms like data caging, providing applications with its own private storage, a third party application will be able to access a lot of potentially confidential data, like contact lists, sms and email storage and even the Blackberry’s microphone. ...

Clients of escorts and call girls are usually aware of the the risks presented from STIs. However, SophosLabs has been monitoring a different type of infection risk for clients of escorts in Indian cities. The Troj/JSRedir-AR infection has morphed slightly: If you look at the variable ‘o[e]‘ (two-thirds of the way down) you will see the beginnings of an obfuscated string ‘http://’. Previous versions of Troj/JSRedir-AK and Troj/JSRedir-AR have used non-alphanumeric characters to disguise the strings.

Security blogger Brian Krebs is reporting that some Windows XP users are reporting blue screen of death on reboot after installing Microsoft’s Tuesday patch KB977165 (MS010–15: “Vulnerabilities in Windows kernel could allow elevation of privilege.”) “Turns out, a non-trivial number of XP users are reporting that their systems suffer from the dreaded Blue Screen of Death (BSoD) and fall into an interminable reboot loop after installing the latest batch of patches from Redmond,” ...

SecurePcAv is a phony antivirus program that has been infecting PC’s across the interwebs in recent days. If your PC is infected with SecurePcAv you will most likely experience the following: Fake system scans that report numerous infections and refuses to remove the supposed infections until you buy the phony software. Alerts and warnings stating the PC is under attack or unprotected and recommends you buy the phony software. Other software will not work, when attempting to open programs a warning stating the program is infected appears and the software is closed.
