Posted by   Virus Bulletin on   Dec 1, 2012

The December issue of Virus Bulletin is now available for subscribers to download.

The December 2012 issue of Virus Bulletin is now available for subscribers to browse online or download in PDF or PRC (Kindle) format.

Some of the things this month's issue has in store are:

  • New tricks ship with Zeus packer: Recently, the Pony trojan (a.k.a. FareIt) has been observed installing a new Zeus sample on users' machines. Jie Zhang takes a look at the new packer tricks that are used by this latest Zeus sample.
  • Compromised library: The Floxif DLL file infector implements both anti-static- and anti-dynamic-analysis techniques. Raul Alvarez describes how.
  • A journey into the Sirefef packer: a research case study: Sirefef is a fast-paced malware family. It frequently changes its obfuscated packer layer in order to avoid detection by AV scanners and to impede reverse engineering. Tim Liu present the technical processes he and his team followed during analysis and examines the anti-debug/emulation techniques used.
  • Part 2: Interaction with a black hole: Gabor Szappanos started with two fairly incomplete sources of information about the latest Blackhole server version: the server-side source code from old versions and the outgoing flow of malware. He describes how, using these sources, he was able to sketch a reasonably good picture of what goes on inside the server hosting the Blackhole exploit kit.

Note: The December 2012 VB100 comparative review will be published as standalone article later in the month. As with all new VBSpam and VB100 reviews, the report will be available for non-subscribers to purchase as a standalone item (Virus Bulletin subscribers will be notified by email when the comparative is available to download). Non-subscribers can purchase VB100 reports here and VBSpam reports here.
