FUU (Faster Universal Unpacker) is a GUI Windows Tool with a set of tools (plugins) to help you to unpack, decompress and decrypt most of the programs packed, compressed or encrypted with the very well knowns software protection programs like UPX, ASPack, FSG, ACProtect, etc.

The GUI was designed using RadASM and MASM. Every plugin included in the official release was written in ASM using MASM.

The core of every plugin use TitanEngine SDK from ReversingLabs under the hood, this help to the developer to write plugins very easy and very fast without the need to worry about some repetitive and boring functions like dump, fix the iat, add sections, etc. You can develop a plugin for FUU in a very easy way using TitanEngine.

Also, FUU include some extra tools like:

Generic OEP Finder

Generic OEP Finder, Cryto Signature Detector and Generic Unpacker are from PEiD’s team.

IMPORTANT NOTICE: A ripped version of FUU is distributed under the name of MART!K Unpacker. This tool does not add additional features to the current ones in FUU. The author of this fake tool just ripped the original strings of FUU (main executable file and plugins) for his own. A mention to the original project (FUU) was added to the post in his blog but the sources were not released and corresponded credit were not added in the executables, indeed, the original author was removed and in his place, the name of MART!K was added. Please, contact anyone in the FUU’s team if you have any further question or if you know about another case like this were FUU is involved.
