XMPPloit explained

XMPPloit is an exploit tool for a so-called “flaw” in the XMPP protocol. It has been published recently under the GPLv3 license, and has received much comment. However, it does not seem anybody took the time to study this attack and explain it.

Goals

XMPPloit is designed to serve as a transparent man-in-the-middle between an XMPP client and its XMPP server, in order to force the client not to encrypt its communications, so that it is possible to read them and modify them on-the-fly.

That allows to force the client to use a clear text authentication mechanism, to display its login and password, and to modify any message it sends or receives.

Do you remember how Intel used to be the white knight of graphic card manufacturers, the one from which you could buy hardware without looking, being sure that it would be supported by GNU/Linux directly?

Do you remember how they broke that by releasing the infamous Poulsbo card?

Well, they did it again. The newest Intel Atom D2500, D2550, D2700, N2600 and N2800 processors, codenamed “CedarView” and “Cedar Trail”, include a graphic core that is only supported by a proprietary driver only available on Meego (read: unusable on regular GNU/Linux.

People that try to do more or less legal business, using Internet in an illegitimate way, for instance (this is a real example, including the spammer's address: spamming bots, please use it ;-) !):
