New Koobface variant saves researchers time from analysis

Published: January 16, 2010 Reading time: 2 min

Researchers at McAfee labs monitor Koobface activities 24/7 via custom honeypots and while reviewing one such update we noticed a variant that had debug/log features. Unlike the traditional captcha breaking technique to create new accounts, this variant of the worm converts the infected machine to a bot. When we analysed the malware trapped in our botnet, we found that this variant of Koobface has a special feature for logging all activities carried out during the infection process in a log file . Log file is created under system root with date and time stamp for eg, C:\fb_reg20090612.log. ...

Consistent Computer Virus Malcode names

Published: January 15, 2010 Reading time: 3 min

InfoSecurity, a great site for computer security news, just put up a story asking the very old question: “Why don’t AV vendors name malcode consistently.” The lead on the piece was: “…Fortinet, Sunbelt Software, and Kaspersky all published their lists of the most prevalent malware strains for the last month of 2009, but they didn’t match up, leading to an admission that users will inevitably be confused by the results.” Great observation, sort of. ...

Rimecud and Hamweq – birds of a feather

Published: January 13, 2010 Reading time: 2 min

Following the addition of Win32/Hamweq to the MSRT last month, MMPC will continue cleaning PCs in 2010 by adding another prevalent worm, Win32/Rimecud, to this month’s removal tool. This is due not only to Win32/Rimecud’s high detection numbers, which immediately follow those of Win32/Hamweq, but also to the similarities the two families share with each other. In fact, as part of its payload, Win32/Hamweq may download Win32/Rimecud, contributing to Rimecud’s suitability as the next target for MSRT. ...

Plenty of Updates on Patch Tuesday

Published: January 13, 2010 Reading time: 2 min

This Black Tuesday was different as anticipated – Microsoft releases only one security bulletin, but other companies “jumped in” and deliver updates now as well. For the windows operating systems, only one Security Bulletin was released. MS10-001 deals with a vulnerability in the decompression routines of the Embeded OpenType Font Engine. This means that especially in Windows 2000, programs like Internet Explorer, Word or PowerPoint for example which render EOT fonts can put the system at risk when viewing manipulated contents. In newer operating systems the flawed code is used differently so that Microsoft assumes that it isn’t exploitable there. ...

BlackBerry Messenger the new vehicle to distribute Hoaxes?

Published: January 13, 2010 Reading time: 2 min

I received an interesting IM from a friend via BlackBerry Messenger [BBM] this weekend. She was worried that it could do damage to her shiny new BlackBerry and, as she knew I work for [a security company], she forwarded it to me for my opinion.

Registered malware

Published: January 13, 2010 Reading time: 2 min

Malware authors love to innovate when it comes to persistence and hiding their nefarious creations from detection, and although most of the schemes are not unknown to analysts, they still show that malware authors are constantly on the prowl and evolving their techniques. The example I have is of yet another registry-centric malware which by the nature of its construction has several advantages to defeating naive security software. The sample, detected as Troj/RegExec-A, is essentially a multi-component threat of sorts comprising of at least 3 components (Dropper/installer, Payload and Loader.) ...
