Just found a vx community that founded by M'sian( lclee_vx). This independent group has quite number of vx sources and techniques available on their web. I just read through the "Cracking Password with Only Physical Access" which demonstrate some kiddie skill, but useful for some particular cases. I also glance through the paper that lclee_vx presented in DEFCON 16 entitled "Comparison Virus on Windows Platform and Linux Platform". I familiar with PE format but yet to learn ELF.
Not sure how active the group now. I will spend my this week time on browsing the site.
