      Antidebugging For (M)asses - Protecting the Enviroment
    ------------------------------------------------------------------------

    SUMMARY

    The whitepaper linked here provides a few examples for antidebugging
    techniques that can be used under the Windows operating system.

    DETAILS

    Introduction:
    The number of computer hackers/crackers have reached a very high level
    recently. It is very hard to develop a product that will be secure against
    reverse engineering attacks, to be const-stricto it is surely impossible.
    However, if we can, why not make their dirty work harder?

    The paper discusses several techniques:
     * Open CSRSS.EXE to detect SEH debugger
     * Use the CheckRemoteDebuggerPresent API provided by Windows XP
     * Protect ExitProcess to detect Softice/D*
