UPX Unpacker

UPX Unpacker addresses PEiD users by offering a plug-in for this particular piece of software. The job that PEiD does refers to the identification of PE (portable executable) files most popular packers, compilers or crypters.

As PEiD’s development has been discontinued and its website is no longer available, Softpedia is one of the few sources that provides the program for download purposes. Last time it was checked, PEiD could easily detect at least four hundred and seventy distinct signatures in portable executable files.

UPX Unpacker empowers PEiD with yet another feature that can help you rapidly and effortlessly unpack the information within an UPX compressed file, whether it is an EXE file or other file types that use the PE format including DLL (Dynamic-link library), object code, SYS (device driver) or even FON (font files).

UPX stands for the Ultimate Packer for eXecutables and has been around for quite some time now, being released back in the fifth month of 1998. It revolves around the UCL compression algorithm, an algorithm that does not take rocket-science to be comprehended before actually creating an app that can successfully decompress the UPX compressed files.

UPX Unpacker is such an application that comes in the form of a PEiD plug-in. All you really have to do is load up your portable executable file into PEiD and check whether it was compressed using UPX or not. You can do that just by inspecting the ‘EP section’ of the program. In order to access UPX Unpacker, you must click on the bottom rightmost button and select it from the ‘Plugins’ sub-menu.

The bottom line with UPX Unpacker is that it serves right a software that has its popularity within the community. At the end of the day, UPX Unpacker is just a plug-in that needed to be created for such software and the fact that it manages to please the user by delivering fast results is exactly what it is supposed to do.
