Tools and communication
Operation Payback members use a modified version of the Low Orbit Ion Cannon (LOIC) to execute the DDoS attacks.[103] In September 2010, a "Hive Mind" mode was added to the LOIC.[103] While in Hive Mind mode, the LOIC connects to IRC, where it can be controlled remotely. This allows computers with LOIC installed on them to behave as if they were a part of a botnet. Utilising this tool, the coordinators of Operation Payback were able to quickly take down websites belonging to anti-piracy groups.[103] Botnets of all sizes have also been used.[104]
Communication consists of an IRC channel where targets are decided upon, after which "attack posters" are produced and posted on the various imageboards (4chan/7chan/711chan/420chan/808chan).[105] Media such as Twitter and Facebook have previously been utilised for co-ordination,[105] but on December 8, 2010 Operation Payback's Facebook page was removed and their official Twitter account was suspended.[89][106][107] Also, according to Valleywag, Encyclopedia Dramatica was forced to delete their article on Operation Payback.[108][109][110]
