There are so few tricks available that I am always curious to see if there is something new in town. So I started poking around Sentinel HASP Envelope for OS X to see what they use to fool my dear debuggers. Well, we have the usual ptrace and sysctl tricks, a check for a kernel debugger (via kernel boot arguments), and, to my (good) surprise, one of the anti-debug tricks I discovered a few months ago.
