Security Focus just posted this interview of me, talking about DRM. Here are a few choice quotes.
On authoring software protection for Vista:
The rules of the game are changing recently with Microsoft Vista kernel patch protection. If you’re a rootkit author, you just bypass it. If you’re a software protection designer, you have to play by its rules. For the first time in the PC’s history, it’s not a level playing field any more. Virus scanner authors were the first to complain about this, and it will be interesting to see how this fundamental change affects the balance of power in the future.
On using custom hardware for protection:
Custom hardware often gives you a longer period until the first break since it requires an attacker’s time and effort to get up to speed on it. However, it often fails more permanently once cracked since the designers put all their faith in the hardware protection.
