Crimepack 3.1.3 Exploit kit Leaked, available for Download! I focus on a malware that exploits a recent JRE vulnerability: CVE-2010-0840. This malware comes inside a jar file, which contains the following two classes: Crimepack.class and KAVS.class. The class is the engine of the malware, it is obfuscated, but you can quickly strip off the obfuscation. The kit contains a nice php script that drops custom PDF-generator on-demand, which means that you can have several mutations of the same piece of malware.
