A colleague recently pointed me towards Korset, a program developed by Ohad Ben-Cohen and Avishai Wool promising features comparable to Extrapol. While I must admit I’m slightly skeptical about the promise of “provable zero false alarm” — since the problem is undecidable, usually people tend to develop “provably complete” rather than “provably sound” analysis — it sounds like an interesting development.

Now, from what I understand, Korset will be presented to Blackhat in a few months, and the rules of the conference forbid the developers from giving away any detail. Until then, we have no way of comparing the unreleased Extrapol and the equally unreleased Korset.

Note: the tarball for the first prototype of Extrapol is waiting on my hard-drive for release clearance. I hope I’ll be able to release it next Tuesday or Wednseday. Stay tuned.
