iat certification

We have discussed how to search for OEP and shelling. Sometimes, it cannot run normally when Dump is out, because another input table is not processed, and some encryption shells will make a big fuss about IAT encryption, replace the actual IAT address with the shell address of the HOOK-API, so that the shelling cannot correctly restore the original IAT of the pr

Analysis of a security implementation method of IAT Hooking0 × 01 Introduction The Hook import table (IAT hooking) is a well-documented technique used to intercept imported function calls. However, many methods depend on some suspicious API functions and leave some features that are easy to identify. This article explores an IAT hooking implementation method that

Hook is a technology that has existed for a long time in windows.Hook is generally divided into two types. Hook Message 2. Hook api this question is about hook api modification IAT. (If you are a hook expert, don't read it)At first, HOOK-API was typically learned by overwriting the address and modifying the IAT method.Through these two technologies, we can basically hook the API functions of this process.
