Next week, in the run up to this years Hacker Halted USA 2009 conference, I'll be delivering a EC-Council webinar covering DIY Malware Construction. The presentation covered the dynamics of building custom malware and making it undetectable to anti-virus - regardless of signature, heuristic or behavioral detection engines (but eventually protectable one the good-guy AV folks finally get a sample and develop a dedicated signature).
If you've got the time, please join the webinar. You can see a line up of past and future presentations here.
With regards to main conference event, well thats not until September 23-25 down in Miami. I'll be presenting on the topic of Factoring Malware into Web Application Design - which will of course be very cool :-)
