Hacking the Malware– A reverse-engineer’s analysis

A nice, thorough analysis of a Yahoo! instant messaging worm by Rahul Mohandas, showing how he decoded the exploit, reverse engineered it, and it's effects. Very good example, and something you can learn from.

This paper attempts to document an approach on how the hackers make use of the vulnerabilities to install malicious software on the vulnerable machine. A comprehensive reverse code engineered analysis of the malicious software (Win32.Qucan.a) and the various protection schemes against the worm by various security products are also discussed.

I also describe an approach to setting up a flexible laboratory environment using virtual workstation software such as VMware, and demonstrate the process of reverse engineering a worm using a range of system monitoring tools in conjunction with a disassembler.

I hope this document will help the Malware researchers, Intrusion Analysts and other Security professionals to conduct a more viable and comprehensive research.
