Automatic Unpacking and The Summer Conferences

We are finishing putting the final touches on our presentations for next week. Saffron, which will be demoed at Blackhat and Defcon, is in good working order. The results are amazing and we hope you'll be able to make our talk. If you can't feel free to catch us around the conference.

Covert Debugging: Circumventing Software Armoring Techniques is on Thursday at 10am in the Augustus 1+2 Ballroom. We'll be giving the same talk, although somewhat shorter at Defcon on Friday at 2pm in the Track 1 speaking area.

Valsmith and HD Moore will also be giving their Tactical Exploitation talk at 1:45pm on Wednesday in the Tiberius Ballroom 3+4+7+8 and again at Defcon on Friday at 4pm in the Track 1 speaking area.

Valsmith and Delchi will speak on Malware Secrets at Defcon, 11am on Saturday in the Track 2 speaking area.

We hope to see you there!

Database speedups and other changes


I made some modifications to the searching engine. I've reworked the search system and backend SQL queries so they are a bit faster. Specifically you'll the new "Thorough" option on the query interface. If you select this searches will take longer but will get more results.

Offensive Computing at Blackhat 2007 and Defcon 15

Offensive Computing team members will be speaking at both Blackhat 2007 and Defcon 15 in Las Vegas Nevada. Danny Quist (Chamuco) and Valsmith will be giving a talk title Covert Debugging: Circumventing Software Armoring Techniques. This is research we've been working on to automatically and generically unpack software.

HD Moore and Valsmith will be presenting a talk called Tactical Exploitation at Blackhat 2007. It will detail methods for penetrating non-standard methods of network penetration and should be very interesting.

We'll be around for both conferences so be sure to find us and say hello!

Hacking Tools Illegal in Germany

Obviously most everyone thinks This is a bad idea.

But I wonder, last year we presented a talk at Defcon called "Hacking Malware" which talked about bypassing security features in malicious binaries. Would this be illegal in Germany? How do you do incident response / forensics and analysis under those types of laws?

Does this mean in Germany someone can hack into a computer and not worry about being analyzed because the tools to do so are illegal?
