By Architecture
Generic helpers for reverse engineering of a specific architecture.
ia32
amd64
ARM
By Operating System
Generic helpers for reverse engineering of a specific operating system.
Windows
Linux
By Compiler
Generic helpers for reverse engineering of binaries generated using a specific compiler.
Microsoft Visual Studio
These IDC scripts help with the reversing of MSVC programs. One script scans the whole program for typical SEH/EH code sequences and comments all related structures and fields. The other script scans the whole program for RTTI structures and vftables.
GCC
Delphi
This script deals with Delphi RTTI structures
Borland
Borland C++ Builder Run Time Type Information (RTTI) support for IDA Pro
By Technology
Generic helpers for reverse engineering of a technology.
COM
The plugin tries to extract the symbol information from
the typelibrary of the COM component. It will then set the
function names of interface methods and their parameters, and
finally add a comment with the MIDL-style declaration of the
interface method.
Remote Procedure Call
mIDA is a plugin for the IDA disassembler that can extract RPC interfaces from a binary file and recreate the associated IDL definition. mIDA is free and fully integrates with the latest version of IDA (5.2 or later)
Cryptography
Generic helpers for reverse engineering of encryption and decryption algorithms.
Signature Based
The idea behind it pretty simple: since almost all crypto algorithms use magic constants, we will just look for these constants in the program body.
The plugin supports virtually all crypto algorithms and hash functions.
Deobfuscation
Plugins and scripts for removing obfuscations from disassembly.
ia32
Optimice applies common optimization techniques on obfuscated code to make it more readable/user friendly. This plugin enables you to remove some common obfuscations and rewrite code to a new segment.
