eXPressor 1.2 - Finds OEP
- eXPressor 1.2 - Finds OEP. (by haggar, 25 Mar 2005)// Script for OllyScript plugin by SHaG - http://ollyscript.apsvans.com
///////////////////////////////////////////////////////////////////////////
//
// Brilliant "eXPressor v1.2.0.1" OEP finder script - by Haggar :-)
//
// I think that you need more time to click on Pluggins menu in Olly
// to use this script, than scroll a litlle bit in CPU window in Olly
// and find jump that leads to OEP ;-) , but maybe this script will
// be of use to somebody.
//
// Script has two ways (methods) to find OEP (in case that one is not
// working try other one):
// 1. way - uses hardware breakpoint,
// 2. way - calculates address of OEP jmp and puts bp on it.
