BadBlue is a P2P file sharing application distributed by Working Resources. It is designed for use on Microsoft Windows operating systems. BadBlue is operated through a web interface, generated by an included web server running on the local system.

A variant to BID 5086 has been reported to exist. Reportedly, EXT.DLL has been re-designed to pass user input to the cleanSearchString function.
