 Forums >>  Debuggers  >>  Help me set breakpoints

Topic created on: June 23, 2012 13:45 CDT by internetuser2k11 .

I managed to bypass the IsDebuggerPresent in Immunity Debugger. Now I want to work with Total Screen Recorder by setting breakpoint on KillTimer() api.
I set breakpoints on IsDebuggerPresent() and KillTimer() apis and break first at IsDebuggerPresent(), and modify the code in kernalbase.dll so that the app runs in the debugger, but after that if I run the app it doesn't break on killtimer() apis. It just shows the app. Please help me to break at KillTimer() apis.

Maybe there are another Anti-Debugging technique used?

Or are you running under a virtual machine?
