Actually it is taking place the 2nd CARO meeting at the Crowne Plaza Hoofddorp in The Netherlans. This year's topic is about Packers, Decryptors and Obfuscators, and indeed some of the presentations are superb. The program is published here. While I'm writing this post, Mike Morgenstern & Andreas Marx, from AV-Test.org are giving a speach about their Runtime Packer Testing Experiences.
In a few minutes we'll have 3 different talks about detection and blacklisting of packers, which is both interesting and controversial.
