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,” ...

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. ...

Bruce Schneier, in his blog Schneier on Security http://www.schneier.com/ drew attention to this great interview with an ex-Nigerian-419 scammer on the Scam-Detective site. It’s a fairly long piece and gives a pretty good view of the Nigerian scam industry run by organized crime, how it sucks in young people who have good computer and English skills and pays them a huge amount of money ($75,000 per year in this case) to scam victims they view as white, greedy and rich. ...

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. ...
