Updated Asprotect AIP script
Hi guys,I had a bit of time this morning and decided to take a look at the features in ODBGScript since 1.41. As a result of the new things implemented since then I have been able to optimise my old Asprotect AIP repair script. As such it now takes you to the OEP and only requires to know if the IAT is corrupt or not, everything else is detected. It also completes the repair in under a minute now, compared to the 5 minutes or so it used to take.
Just thought I'd share it up.
I might quickly also point out that it uses the INT3 method of getting to the OEP so there is a high chance it won't work for some targets... I will put up another copy later that just rebuilds the AIP just in case.
// Optimized AIP repair script for Asprotect by D3XT3R.
//
// It is believed this script should be completely accurate. Check all exceptions except INT3 and Custom Exceptions and this script will
// take you to the OEP and repair the AIP ready for dumping.
//
// This script will ONLY run on ODBGScript v1.67 or higher. If you try to use this with any other plugin or a lower version DO NOT
// expect me to give you any support what so ever.
