Xchat is a multiplatform IRC client , if you use it someone can easily know what version your using and sometimes the

Operation system your using which will effect your security sometimes .. for example

>Qnix< CTCP VERSION
* Received a CTCP VERSION from Qnix
-Qnix- VERSION Xchat 2.* (gentoo ..etc)

as you can see it replays the Xchat version “which might be vulnerable to some kind of bug which might effect your security if someone’s using a worm that searches and hack these versions” and it displays the operation system..

to fake these information go to Settings -> Advanced -> CTCP Replays..

and click on Add New then add VERSION as a name and CTCP %s VERSION mIRC 5.91 (16 bit) for Microsoft © Windows For WorkGroups 3.11® as the command

then close your Xchat and edit this file ~/.xchat/xchat.conf and search for irc_hide_version = 0

and set it to irc_hide_version = 1

then run your Xchat again and the VERSION will be faked
