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.

The Zeus crimeware family has moved into new territory with its latest spam campaign – purporting to be a warning about targeted phishing attacks on “.gov” and “.mil” domains, by Zeus Trojans no less! In fact, one of the latest spam samples we’ve seen, duplicates the title and first three paragraphs of a blog entry by well-known security expert Brian Krebs, which discusses a previous iteration of this Zeus attack. As seen below, the spam sample starts off with the same three lines of the blog post, before starting into the phony KB content and links that lead to Zeus malware. ...

It has been barely two days since Google announced their new social integration and messaging tool called Google Buzz. Today we saw the first example of malware, W32/Zuggie-A, pretending to be Google Buzz. Analysis of W32/Zuggie-A gives the impression of a hastily assembled worm, really a modification of the W32/SillyFDC family of worms but with a twist. When W32/Zuggie-A is installed, it creates the following files: Program Files\Mozilla Firefox\extensions{9CE11043-9A15-4207-A565-0C94C42D590D}\chrome\content\timer.xul Program Files\Mozilla Firefox\extensions{9CE11043-9A15-4207-A565-0C94C42D590D}\chrome.manifest Program Files\Mozilla Firefox\extensions{9CE11043-9A15-4207-A565-0C94C42D590D}\install.rdf System\googlebuzz.exe – copy of W32/Zuggie-A System\GoogleUpte.exe – copy of W32/Zuggie-A W32/Zuggie-A modifies the registry to autostart GoogleUpte.exe and googlebuzz.exe. A quick search shows that the CLSID: 9CE11043-9A15-4207-A565-0C94C42D590D has previously been seen in multiple worms. This supports my theory that this is a hastily assembled worm built from recycled malware. I fired up a copy of Firefox on the infected machine and, as determined from analysis, found an installed Firefox extension called Firefox security 2.0 – Internal security options editor under the extensions tab of Firefox Add-ons. This “security extension” has added a JavaScript (timer.xul), which is triggered when the browser queries: yahoo.com, bing.com, google.com, aol.com/aol/search, ask.com and executes JavaScript hosted on: searchrequest1 . com / request . php ? aid = blackout which will silently click all Google or Yahoo Ads. displayed on the search results page (hey why not make a few bucks while infecting eh?). Google Buzz is new and is garnering quite a bit of interest and adoption among Internet users including myself. Clearly the malware authors view Google Buzz as the fresh big lucrative social fruit to exploit much like they have done with Facebook, MySpace, Hi5 and others. So in the coming weeks and months I predict we will see a host of new malware exploiting or attempting to exploit Google Buzz as the malware authors figure out its internals. This may have only been an exploratory attempt or a quick response to the latest craze – only time will tell.

Several reports have been published detailing a Blackberry proof of concept (PoC) exploit called txsBBSpy that was recently presented at a security conference. Although it may not have been the aim of the original presenter, some reports have framed the PoC as being able to exploit so-called vulnerabilities that the writers believe to be present in the Blackberry platform. The “vulnerabilities” involve secretly forwarding incoming emails, locating devices by way of their GPS capabilities, eavesdropping on conversations by surreptitiously turning on microphones, and other such nefarious behavior. ...

Fake antivirus software (a.k.a misleading applications or rogue antivirus) is big business nowadays with Symantec reporting 43 million installation attempts from over 250 distinct programs between July 1, 2008, to June 30, 2009. With fake AV software costing the victim anywhere from $30 to $100, this is a lucrative earner for criminals. Over time Symantec has observed various social engineering tactics being used to try and entice victims to hand over their money in this scam. The fake antivirus software known as Live PC Care has now gone as far as offering live online support to potential victims. Once a victim has installed Live PC Care onto their system via a system exploit or social engineering tactics, they are presented with the screen below falsely informing them that their system is riddled with viruses. Any suspicious computer user might wonder what this software is and where exactly it came from. To alleviate doubt and to aid with the whole scam, the designers of Live PC Care have added a yellow online support button in the top, right-hand corner of the fake AV software. ...

Our good friends at Broomfield, Colo., security firm eSoft have found an interesting scam to trick Internet users into installing the Hotbar adware: a fake Firefox download site. The eSoft researchers are theorizing that an affiliate of Pinball Publisher Network (PPB). is responsible. Pinball bought the Zango assets after that pestilent operation failed last spring. However Sunbelt Software Spyware Research Manager Eric Howes did some more digging and found that PPN offers the download file on a site they own so affiliates can send customers victims there for downloads. ...

Found this little gem today. It’s distributed with other malware, cracks and drive-by downloads. It purports to be a security warning from your Windows operating system. Notice the “Visa, MasterCard, etc” – it doesn’t even bother to list all the cards it accepts. The really cool thing about it is that it takes FAKE credit card numbers as well as real ones!

With virus and spam outbreaks, analysts needs to keep their nerves to analyze the situation and proceed to deal with the new threat. So, I wasn’t expected to be surprised by my friends’ actions on facebook this past weekend. It started innocently enough, as a post about getting a Free $25 Starbucks gift card for joining a particular group. The first person to join the group from my friends list happens to work for a non-profit organization helping young people. So, I expected the young people on his “friends list” to join this group shortly. ...
