Crimepack exploit kit
Posted: 08 Mar 2011 03:07 PM

The Crimepack exploit kit was among the top-selling underground commercial software applications in 2010.   As with other kits of this kind, Crimepack consists of a number of exploits.  The types of exploits in the kit vary, depending on the version of the kit.  The Crimepack kit initially appeared as version 2.1 at the end of February - beginning of March 2010.  Later, other versions were found "in-the-wild," including v2.2.1, v2.8, v3.0, v3.1.0, v3.1.2, and the latest, v3.1.3. The kit is packed with a commercial PHP encoder. When it is sold - and tied to the buyer's domain - it is based on PHP and a MySQL backend and has a really fancy, feature-rich admin panel that includes a choice of exploits to use and redirection of nonvulnerable traffic. Statistics in this kit are shown in one table under the MAiN tab and provide such information as overall statistics, exploit statistics, operating system statistics, browser statistics, and referrers' and victims' countries.

Crimepack has several features that make it look different from its competitors' versions. An "iFrame obfuscator" feature produces already obfuscated JavaScript code, which can be posted in compromised sites. The obfuscation algorithm used in version 3.1.3 is very simple and could easily be reverted. The obfuscation algorithm source code is not encrypted with commercial Cryptor, which allows criminals who purchase this pack to use a custom obfuscation or encryption algorithm. Another feature is a "Blacklist checker," which checks the domain where it is installed against the blacklists of famous security companies. If the URL appears in a blacklist, the checker will notify the domain owner of the kit. This kit also has a "Downloader builder," which takes a URL as an argument and generates a Trojan - Downloader - RootKit executable.  The executable has a detection rate of 17/43 on VT.
