PACE/Ilok is mostly loved by the audio industry, and since we crackers don't care too much about hardcore audio apps PACE is not well documented. But this protection is actually quite decent and fun to reverse, it is not especially hard but enough to stop most mediocre crackers. However one aspect could be especially hard for the less determined. That is the driver TPkd.sys, it has some nice features that can stop you dead in your tracks. In this paper I will discuss in my opinion the best aspect of this driver, resolving the int3 stolen calls.
