About This File

This plugin make it possible to pass debuggee to another debugger without restarting (like VM live migration). Each debuggers have both strong and weak points compared with others.

We can get only strong point of each debuggers by debuggee migration, e.g. Using OllyDbg to bypass antidebug and detect OEP, after that using Immunity Debugger to fix obfuscated import table.

Very simple overview:

  • OllyMigrate = Debuggee live migration plugin

Features:

  • Various debuggers supported
  • Migrate debuggee between each debuggers
  • Multi thread and suspended thread aware (running state not required)
  • Migrate software breakpoint settings (keep enabled/disabled status)
  • Migrate selected address of disassemble, memory and stack window

  • OllyDbg version 1.10 (tested 1.10)
  • OllyDbg version 2.01 (tested 2.01)
  • Immunity Debugger version 1.8x or higher (tested 1.85)

  • x64dbg (tested 20170822 snapshot)

How to use (OllyDbg example):

  1. Install "same version" plugin to sender(src) and receiver(dst) debuggers.
  2. Start sender debugger to add receiver debugger definition.
    Menu > Plugins > OllyMigrate > Options
    Input debugger info
    Path: receiver debugger path (Click [Browse] and select file)
    Tag:  anything is ok (identification only)
    Args: debugger command line argument (usually not need to change)
    Click [Add] and [Save]
  3. Open debuggee using sender debugger. Start debugging (e.g. until detect OEP)
    After that switch to another debugger. Paused status is recommended.
    Menu > Plugins > OllyMigrate > Send Debuggee
    Select destination debugger and Click [Migrate]
  4. Receiver debugger startup automatically and receive debuggee.
    Continue debugging.
