Part 2 of User-Mode Debugging Internals Article

I’ve almost finished setting up the remaining parts of my blog. I’ve added an About page and pretty much filled my BlogRoll with the blogs I try to read daily. Thanks to everyone that’s visited/linked here in the last few days.

I’m currently working on the “Publications” page of the blog to have a central repository with all my data. I will also duplicate it on OpenRCE, but that site requires a login, and I wanted to make sure anyone could freely access my stuff. The links aren’t live yet, but they should be within the day.

Also, Part 2 of my article should appear soon, but for those that want to beat the clock, you can download it for now directly here. If you haven’t read Part 1 first, make sure you do here.

Brief overview of what’s discussed:

  • Part 1 – Win32: DebugActiveProcess, DebugBreakProcess, DebugSetProcessKillOnExit, CheckRemoteDebuggerPresent, WaitForDebugEvent, ContinueDebugEvent, DebugActiveProcessStop.
  • Part 1 – Win32: Teb->DbgSsReservedData[0] and DBGSS_THREAD_DATA. SaveProcessHandle, SaveThreadHandle, MarkThreadHandle, MarkProcessHandle, RemoveHandles, CloseAllProcessHandles.
