Unofficial PDK v1.03 for Immunity Debugger

Original project page : http://bob.droppages.com/Projects/Immunity+Debugger/PDK

Long ago in November 2008 I created an unofficial Immunity Debugger PDK, and I have now updated it in 2011 for the Immunity Debugger v1.8x plugin format changes.

Plugins created with this PDK are compatible with old and new Immunity debugger, and also OllyDbg v1.10 and it’s many variants (OllySND, OllyDRX, CiM’s Olly, OllyShadow etc)

No modification (like my FixPlugins tool) is needed for this compatibility, just copy to the plugins path for the debugger and it will be in the list. A simple plugin is included – WinMax – which you can use to test in your debugger versions. As always, full source is included for the PDK and example plugins.

If anybody wants to convert the PDK into another language then please do, but please send to me for inclusion in the distribution.

Technical details: The PDK contains initialization code that will alter the Exports in memory to suit the debugger that is loading the Plugin. The debugger is first detected using a simple test. The usual implicit Imports are instead dynamically resolved during initialization, which allows the use of any name for the debugger exe – useful if some program is looking for default debugger process names.

Immunity Debugger Plugin Fixer Tool v1.01

Original project page : http://bob.droppages.com/Projects/Immunity+Debugger/FixPlugins

This is a small tool to convert old Immunity Debugger plugins to be compatible with the Immunity Debugger v1.8x changes. The tool also works with OllyDbg plugins, and comes with full source.

Simply drop old plugin(s) onto the FixPlugins.EXE and a new file will be generated which will have Imports and Exports fixed to be compatible.

Technical details: The imports are first converted to ordinal values, and then mapped to the new ordinal order using a simple table. For OllyDbg also the module name is changed to be “ImmunityDebugger.exe”. The exports are simply incremented (skipping the old underscore) for Immunity Debugger, and in the case of OllyDbg Plugin then the prefix is rewritten to be “IMMDBG_”.

NOTE: This tool makes modifications to the PE headers of the file, thus it will not work with compressed plugins!

NOTE2: Not all OllyDbg plugins will work, specifically the ones that patch OllyDbg – obviously because it will patch the bytes of Immunity Debugger instead of OllyDbg!
