HIVEMIND mode will connect your client to an IRC server so it can be controlled remotely. Think of this as a voluntary botnet. Please be aware that your client can potentially be made to do naughty things.
Note: It does NOT allow remote administration of your machine; it just providees control of LOIC itself.
If you want to start up in Hivemind mode, run something such as this:
LOIC.exe /hivemind irc.server.address
which will connect to irc://irc.server.adress:6667/loic
You can also specify a port and channel:
LOIC.exe /hivemind irc.server.address 1234 #secret
which will connect to irc://irc.server.adress:1234/secret
In order to run Hivemind Hidden mode, run something such as this:
LOIC.exe /hidden /hivemind irc.server.address
which will connect to irc://irc.server.adress:6667/loic without any visible GUI.
