Re: Old IRC Client bug Re-Applied

As far as I knew, Pirch development was discontinued quite sometime ago
(although going to the official home page now reveals they've got a new
domain), so if thats the case, fixing this bug will be up to the
individual user.. although the VAST majority of windows IRC users use mIRC
anyway...

If this has already been announced, well, screw me.

Problem:
The IRC (Internet Relay Chat) Client, pIRCh automatically assigns
your main pirch directory to where DCC downloads are sent.

Exploit:
You can replace someone's script file with a malicious one,
therefore recieving control over an ignorant irc tenant. This can be
done by sending a replacement file via DCC to the user. Most
people could tell the user that it was something cool, and they
would accept it.

Fix:
Simply goto Tools.. then Preferences. Flip to the DCC tab and
change your default DCC recieve directory to something that is not
the main pIRCh directory.

Tested On:
pIRCh32 0.92
If there's a new version out that fixes it, well crap, I'm sorry for
taking up your time.
