From the doc: 'UPLOAD Coresrv.exe and Coresrv.dat into victims Windows Directory. Execute Coresrv.exe and your IRCD is now running. Works on Win XP also. Coresrv.dat is the IRCD Config file and you may want to edit it with a tect editor before deployment. By default the IRC Server will listen on port 80 so to connect type /server ipaddressofvictim 80 To use extra ports uncomment the Port lines in the Config by removing the # and save it. Using port 6667 is more or less a dead giveaway so be creative in what ports you use or connect bots to.'
