What is "winmx"

WinMX (Windows Music Exchange) was a freeware peer-to-peer file sharing program authored by Frontcode Technologies that ran on Microsoft Windows operating systems of the time, created in 2000. According to one study, it was the number one source for online music in 2005 with an estimated 2.1 million users. Frontcode itself abandoned development of WinMX in September 2005, but a community of developers brought the service back online within a few days by releasing patches or new host files. In North America, WinMX has been eclipsed by other networks such as gnutella and eDonkey as well as to the BitTorrent file transfer protocol.

In May 2011 the WinMX WPNP network came under attack causing WPNP network searches to return random results. Many users of the WinMX software are still utilising the OpenNap functionality which remains unaffected by the attacks. Efforts are still under way to develop a new client that will be compatible with the old one, which is believed to no longer be affected by such WPNP specific network attacks.
