it's possible to spam a user with a non-exsistant file using mirc to another person using mirc if they have accept incoming files from everyone.
a simple command of /dcc send <nickname> < OR /dcc send <nickname> >
will intiate a file transfer of file _ to the user without checking to see if file exsits. proof below:
DCC Send of > to kicktd complete (00:00:01 0.00 KB/Sec)
-
DCC Get of _ from kicktd complete (00:00:01 0.00 KB/Sec)
this does not work in other IRC chat programs. I have tested in X-chat and you will get the error:
--- Received a malformed DCC request from kicktd.
--- Contents of packet: DCC SEND > 1154773822 1028 0
Please do not use this as a means to spam users with dcc get requests
