[What is IRC?] IRC stands for
"Internet Relay Chat". Jarkko Oikarinen originally wrote it in 1988. Since
starting in Finland, it has been used in over 60 countries around the world. It
was designed as a replacement for the "talk" program but has become much, much
more than that. IRC is a multi-user chat system, where people meet on "channels"
(rooms, virtual places, usually with a certain topic of conversation) to talk
in-groups, or privately. There is no restriction to the number of people that
can participate in a given discussion or the number of channels that can be
formed on IRC.
[An introduction to the way IRC works]
All the communications in the world of IRC are done through the server.
(This does not includes the DCC (Direct Client Communication) protocol) When
you connect to a server, you send it 2 commands: NICK & USER. These commands
are used to identify you on the IRC. Here is the format of the commands:
NICK nickname - Sets your nickname USER username host server :real name
- Set your userid and real name. Host is your host and server is the server you
are connecting to. For example to open a raw IRC session you can telnet to
an IRC server on port 6667 or 7000 (the standard ports). Here is an example for
telneting my localhost (note: the lines beginning with * have been written by
me. The rest are the output I got from the server): * nick ^TCG^ NOTICE
^TCG^ :*** If you are having problems connecting due to ping timeouts, please
type /notice E3AA3478 nospoof now. PING :E3AA3478 * user ^TCG^ 127.0.0.1
localhost :The Cyber God :localhost 001 ^TCG^ :Welcome to the DALnet IRC
Network ^TCG^!~tcg@thegod.actcom.co.il :localhost 002 ^TCG^ :Your host is
localhost[thegod.actcom.co.il], running version dal4.6.7.DreamForge.win32
:localhost 003 ^TCG^ :This server was created Fri Jul 24 07:48:52 1998
:localhost 004 ^TCG^ localhost dal4.6.7.DreamForge.win32 oiwsghOkcfrRaAb

users: 0 Max: 0 :localhost 422 ^TCG^ :MOTD File is missing :^TCG^ MODE
^TCG^ :+iw ...
ok
As you can see, the second parameter of the USER commands includes my IP. You
might be thinking right now that you could enter any IP you want and fake your
IP. Well you are wrong. On really older versions of the IRC daemon (Those that
were used in Efnet), you WAS able to spoof your IP. But today there are 2 types
of antispoof-patches: The one that doesn't care about the IP you entered and
connects you using your real IP (which it gets from the socket) and the other
one just doesn't allow you to connect to the server until you give your real IP
address. The first method of Anti-Spoofing is most used most in the server
version of DALnet and the second is used most by EliteIRCD (which is based on
DALnet) and the servers that are based on it. Now, if it all goes ok then
you just opened a raw session to IRC! All the data transferred to the user
(Private Messages/Notices and Channel Events) is transferred from the server. If
the user that sent you a message is on a DIFFERENT server than you (but NOT a
different network) the message "moves" from the servers until it reaches your
server and you. To send someone a message in our raw IRC session type: 'PRIVMSG
nick :message' (without the quotes) where nick is the target nickname and
message is the message (You must include a : before the message). When a
message moves from server to server it looks like this: :SenderNick PRIVMSG
nick :message All the IRC commands move from server to server like this. For
example when someone uses the NICK command ALL the servers get a notice about
it.
[Some notes on different IRC networks and
their daemon software] Different IRC networks have different IRC
daemons. It is important to know the futures / limits of the server your network
uses. For example, OLD Efnet servers don't know the +b channel mode (ban
someone). When trying to start IRC wars you need to know what are the
limitations of the server. If it got services, if so does they have a bug that
can crash them? Can you obtain Channel Operator in a net-split (we'll get to
that)? And so on... During the rest of this tutorial we will discuss different
daemon software and bugs, as well as different ways to "get in".
[Why IRC wars started?] Generally,
IRC wars started on the IRC network Efnet. In this IRC network you can't
register your nickname so ANYONE can use it. If for example someone logged to
this IRC network (By the way, did you know that it is the first IRC network ever
(!)) and he saw that his nick is taken. He probably said something like "How
Rude?!" or "Mother-F*cker" or anything else. Then he started thinking about ways
to get this user off the server. Users started to try many different things on
each other and that's pretty much how IRC wars started. Today, users might start
IRC wars "just for fun", or for taking over channels they don't like or kicking
off users they don't like.
[What do the others know about me?]
OK people! This is actually the first important thing about the IRC wars.
Before starting out you need to know what others can find out about you and what
can you find out about them.
If you are not connected through a BNC, firewall or a shell (we'll get to
this neat stuff later), what I mean, that if you are connected directly to the
IRC, using a dial-up for example users can first of all knows your IP. Newbies
might say right now, ok... well.... So he knows my IP... who gives a shit
anyway? Well if you said this you are wrong. Let's take a look on my host
(resolved IP) for example: P34.haifa2.actcom.co.il
| | | |_ You can see that my ISP is in Israel, and so am I (unless
| | | I'm dialing to foreign ISPs just to cover my identity, which
| | | is a thing people don't do because of... financial issues).
| | |_ You can see that my ISP (Internet Service Provider) is Actcom
| |_ You can see that I am from Haifa ).
|_My modem number at the ISP's office. See how many things the host gave
you? 1) My ISP 2) My city 3) My country Now You can also know
that if my ISP address is actcom.co.il you can send complains about me to
abuse@actcom.co.il for example, give them my IP and tell them what I did to you
and they will do the rest.
That is what users know about you. Some times you will only see numbers like
19.114.47.1 and not the host. That is because the server failed to resolve your
hostname. To resolve it you can download a program called 'nslookup' from
somewhere (note: nslookup comes with all Unix systems), give it the IP and it
will try to resolve it. Also see the entry 'DNS Servers' in the Newbies Corner.
Now, for those who don't know you can get the IP/host by "whoising" the
user. To do a whois on a user in mIrc, BitchX, IRCii, Pirch and some other
known IRC clients all you need to do is type /whois nickname To whois
someone in our raw connection (the one I taught you how to establish at the
beginning) type 'whois nickname' (without the quotes) Here is what I get
when I whois my self in the raw connection: whois ^TCG^ :localhost 311
^TCG^ ^TCG^ ~TCG thegod.actcom.co.il * :The Cyber God :localhost 312 ^TCG^
^TCG^ localhost :test server :localhost 317 ^TCG^ ^TCG^ 9 932030074 :seconds
idle, signon time :localhost 318 ^TCG^ ^TCG^ :End of /WHOIS list. Ok,
before I explain what you got here, here is the format: Format: :server-name
raw-number sender target data. Server-name is the server that gives you the
data. Raw-number is the ID of the data you got (it is used to determine what
data you are getting). Sender: the senders nickname (you!!). Target: The
target (The nick you are whoising). Data: The data. Now here is an
explanation on all the 4 lines In the first one you see the user-name and
the host of the user, you also see his real name: ~TCG thegod.actcom.co.il * :The Cyber God
| | |_ The user's real name (you can fake this :))
| |_ The user host or IP
|
|_ The username (set by IdentD, will be explained later,
when followed by a '~' you see that the IdentD is NOT
running and the Ident (username) might be fake).
The second line:
localhost :test server
| |_ Comment about the server (set by the server admin)
|_ The server that user is connected to Third line:
9 932030074 :seconds idle, signon time
| |_When the user signed in
|_ How many seconds has he been idle Last line:
:End of /WHOIS list.
|_ Shows you that there is no more data. Also,
when users know your IP they can start almost any Denial of Service (DoS) attack
on your host like WinNuke (Arggg... Lame Lame Lame!!!) or a lovely ping flood
that will chew up all of your bandwidth, depending on the attacker's bandwidth
(for more info and more sophisticated DoS attacks, see the DoS tutorial at
blacksun.box.sk).
[How to spoof / hide your identity on the
IRC] After seeing what users can find out about you, it is time to
learn how to hide your identity.
There is no easy and lame way to do this. Here are the most knows ways:
FireWall, WinGate and a Bouncer aka (As Knows As) BNC. We will start from
the firewall. The firewall we are talking about is software that runs on
some machine and is used to filter incoming packets (packets that arrive to the
machine which is running the firewall) and outgoing packets (packets that are
sent from the machine which is running the firewall). Some firewalls are not
configured very well and allow anyone to connect to them. The hard part is to
find a working one that will allow you to use it to connect through it, and once
you are connected, using it so users that will whois you or dns you will see the
firewall's IP! If, for example, there is a misconfigured FireWall on the host
firewall.someone.com, you can use it in mIRC, for example, by starting the mIRC
program (I use the newest version 5.6, go download it at www.mirc.co.uk) and:
1. Click on the Files menu, then Options. 2. On the topmost label of the
tree where you can see 'Connect', If you see a '+' next to it click it. If you
see a '-' go to the next step 3. Click on the sub-item Firewall (duh...)
4. Be sure the 'Use SOCKS firewall' checkbox is marked (has an 'X' in it).
5. In the Hostname field, write the IP / Hostname of the firewall. For
example lets use firewall.someone.com 6. Leave the USER ID and PASSWORD
empty, and make sure the port in 1080. 7. Click OK. Now, next time you
will type /server ... To connect to the IRC server the connection will be
relayed through the firewall, so if someone will whois you he would see
something like this:
:localhost 311 ^TCG^ ^TCG^ ~TCG firewall.someone.com * :The Cyber God
:localhost 312 ^TCG^ ^TCG^ localhost :test server :localhost 317 ^TCG^
^TCG^ 9 932030074 :seconds idle, signon time :localhost 318 ^TCG^ ^TCG^ :End
of /WHOIS list.
You can see that my host is NO LONGER thegod.actcom.co.il, instead it is now
firewall.someone.com!! Now I am protected. You might be asking right now
where to get the firewalls hosts. One idea is go asking your friends. Other is
going to Altavista (www.altavista.com) and searching for "firewall AND list" and
stuff like that.
Another way of spoofing your IP is a WinGate. WinGate is software for Windows
that is used to let several computers that are connected through a local network
of some sort to use one computer's Internet access. It also allows you to fake
your IP _EXACTLY_ the same way. After installing WinGate, anyone will be able to
use it if you don't configure it well (I personally recommend using SyGate
instead). To find Wingate addresses you can ask your friends, run a Wingate
scanner that will scan whole subnets for Wingates or look for lists on the web.
Note: newer versions of the IRC daemons will automatically check for an open
Wingate or a firewall, and if they will detect one they will kill your session
and might even K-Line (Ban the host from using the server/network) the host as
well.
Now, on to the Bouncer (aka BNC) spoofing. Bouncer is software that runs
on Unix computers. If, for example, there is a BNC on bnc.shell.com on port
1234, you can connect to it by typing: /server bnc.shell.com 1234 After that
you should be getting something like this: -BNC- Please type your password
via /quote pass Crap... You need a password. If you know the password you
have no problem. Just type '/qoute pass password' (without the quotes), and
replace 'password' is your password. If you don't know the password you need
to ask the guy that gave you the BNC (or you could always hack the server... ;)
but this tutorial is about IRC warfare, not hacking servers and getting
passwords). You should also ask him if it (the BNC) has vhosts. Vhosts are
multiple IPs and hostnames for the same BNC. If it has vhosts, you can set your
active host by typing '/quote vip the.host.name.here' (as you should be able to
figure by now, it is done without the quotes).
After this you type '/conn server'. For example /conn irc.dal.net will
connect you to irc.dal.net with the bouncer's host.
Note: unlike firewalls and badly configured Wingates, the server cannot
detect a BNC, so there is no chance you will be banned for using it.
[Bans and how to bypass them]
Channel Operators might ban you after you have done something in their
channel that made them angry :( . To bypass a ban you first need to know the
ban type. There are a few ban types: 1. nick!*@* - Bans you by your
nickname. All you need to do is change your nick (by typing /nick newnick, or in
raw session NICK newnick) and you can reenter the channel. 2. *!user@* -
Bans you by your Ident (UserID). If your computer is not running an IdentD
daemon (A win9x with mIRC for example) you can easily change your Ident by
clicking on the File menu, selecting Options, opening the 'Connect' sub-tree,
clicking the IdentD label and changing the User ID. If you are under a Unix /
Linux machine that is already running an IdentD daemon, you can't change it
because it automatically sets your ident username to your login name. To change
this you need to logon to the IRC through a Bouncer because bouncers fake you
IdentD. 3. *!*@host - You are banned by your IP / host. All you need to do
is to connect through a firewall or a Wingate. Some times the bans are more
complex like ^TCG^!*@*.actcom.co.il. This ban will prevent anyone named
^TCG^ with host that ends with .actcom.co.il If you are interested here is
the format: Nick!user@host / IP
| | |_ The IP or hostmask.
| |
| |_ Your username. The IdentD sets this. When running IdentD daemon it
| mostly not faked but when running windows or connection through a
| bouncer it is probably faked.
|
|_The user nickname. If might also contain wildcards like *T*C*G*.
This will prevent anyone with the letters T, C and G (in this order)
to join the channel. Examples: ^TCG!*@*.actcom.co.il
| | |_________The server
| |_Your Ident user (defined as the wildcard '*', meaning ANYTHING)
|_Your nickname As
you probably know, channels have different modes. For example +o to make a
certain person an OP (Operator), +b to ban a person etc'. To set a ban you type:
/mode #Channel +b nick!user@host and to remove a ban you type /mode #Channel -b
nick!user@host On a raw session you don't need the '/'.
[I don't like your nickname... / Getting a user
off the IRC] The easiest way to get a user off the IRC is using a
program called "Click2" for Windows. If might not always work and it is
considered extremely lame, but it might work sometimes. After you got this
program, do the following: 1. Set the "Packets to:" option box to "Clinet"
2. In the Server textbox fill-in the TARGET server. You can figure it out by
doing a /whois or a /dns on the target's nickname. 3. In the Client textbox
fill-in the TARGET IP address. You can also figure this by doing a /whois or
/dns on him but if he uses any spoofing technique like a BNC or a Wingate it
won't harm him even a bit (it may harm the Wingate / Firewall / BNC, though).
4. Be sure that you set it to send 64 packets every 1000ms in the 2
textboxes at the end of the window. 5. The client start port should be 1024
and the stop 1500. 6. Now hit nuke.... This is what you will see if it
worked and you were in a channel, and the target in also in this channel:
*** Quits: ^TCG^ (Connection reset by peer) (Or something likes this)
The target should see something like this: *** [10053] Software caused
connection abort
If it is not working, you won't see anything and he won't either. If he is
running some packet-logger that logs ICMP packets he will see your IP but most
users do not run these.
Another lame way is to try winnuking the address. I won't explain here how to
do it and what winnuke is because it has nothing to do with this tutorial (see R
a v e N's DoS tutorial for Winnuke information, as well as information on more
sophisticated attacks).
Here is a more complex way. You will need a flood program like "Floods".
(Ask me if you want it) After running it or any other flooding script that
is based on clone loading you connect the clones to the target IRC server. (~6
clones should do the job) Before we continue, I want to explain you how this
works. Each user on the IRC got something called SendQ and RecvQ. They
contain the data the user is sending / receiving. They also have a maximum
value. If this value is achieved, the server will automatically close their
connection. Flood programs and flood scripts load clones (computer-operated
IRC "users") and start sending lot of crap to the target nick, causing his RecvQ
to fill up and he should get disconnected :).
So after you launched the program, you start flooding. I can't tell you
exactly how because there are lot of programs and I can't explain you how every
one works, but I can help you via my e-mail: talrun@actcom.co.il There are
also more advanced programs that support clone loading through firewalls and
Wingates. When a user loses his connection to the IRC because of such an attack,
everyone on every channel he was present on will see the following: ***
Quits: ^TCG^ (Excess Flood)
Another way of disconnecting a user from the IRC is exploiting a bug in his
OS. You need to determine his OS and start this attack on him. There are lots of
different types of attacks. To learn about them, read R a v e N's DoS tutorial.
[Can I get caught and will I?] First of
all, it depends on what you are going to do or already did. When you are
going to take over a channel for example, if you are doing it without hiding
your identity first (See previous chapter) you can get caught but nothing will
probably happen to you. You might receive a DoS attack that can terminate your
IRC session or lag you like hell. If you are using a bouncer for example, you
won't get caught for this. But if you "click" someone and he logs the packets he
can e-mail your ISP with your IP and they might kill your account.
If you are killing someone with a netsplit (See next chapter) you won't get
caught and nothing will happens to you since you haven't done anything illegal.
Also, it is good to know as much as possible about your target. If you see
some one that is named 'Ass^Hole' for example, you have no good reason to go
packet him or flood him. He might have access to an OC3 or a DS-3 line
(Extremely fast connections to the Internet) and he might also detect your
attacks and start flooding you in return. Trust me, you don't want this to
happen. One day my T3 line got ping flooded from an OC3 line and it stopped
working for about 30 minutes. Just for your information, OC3 can transfer up to
255Mbit and a T3 can transfer up to 9Mbit (I think). If such a line will flood
your computer you don't stand a chance.
[What are netsplits and how can they help
me?] Large IRC networks consist of various servers. A NetSplit
occurs when a link between one of the servers and the others gets broken because
of lag or other reasons. All users that were connected to this channel will be
separated from the others as long as the netsplit occurs. Therefore, lots of
channels become empty, and get closed. When you will join a channel that became
empty, or you left only 1 user in the channel and you will cycle it, there is a
chance that you will obtain the channel operator status (OP, @). On a
NetJoin (When the server relink to the entire network again) you might still
have the channel operator status. On new servers, you won't get the operator
status when the network is in a spilt mode, but if you could find an old server
or network you just might get lucky. Breaking a connection between 2 servers by
yourself is very difficult. You need to pick 2 servers that are already lagged
and start ping-flooding the target server from a fast connection. Once a
netjoin occurs, it is recommended to have a war script (we'll get to those) that
will DeOP everyone on the channel so other OPs won't be able to DeOP you.
NetSplits can also let you disconnect a user from the IRC. Let's say you want
to disconnect a user named 'Lamer'. When a netsplit occurs, there are two
different possibilities: 1) The target user ('Lamer', in our case) was on
the server that did the netsplit and has left the IRC network, but will return
once a netjoin occurs (shouldn't take a lot of time). 2) The user is still
on the network and has nothing to do with the netsplit. If number 1 occurs
then all you need to do is connect to the network using his nickname and wait
for the netjoin. When the servers will re-link they will see that there are 2
users with the same nickname. Such thing cannot possibly happen, so one user
must be killed. The user that was NOT on the network, (which means he was on the
splitted server) will probably get killed. If option 2 occurs then all you can
do is to put a clone (open another IRC sesssion), connect to the splitted server
and change your nick to his nick. When the servers will rejoin there is a small
chance that he will get killed, so cross your fingers. :)
Now, for the 1,000,000$ question: how do I detect a netsplit? You can detect
a netsplit if the user(s) quit message is "Server1 Server2". For example: Lamar has quit IRC (irc.magic.com irc.freei.net)
| |_Server2
|_Server1 This
message tells you that there is a split between irc.magic.com and irc.freei.net
The second server (Server2) is the server that left the net.
[Channel Takeovers] Channel takeovers
are used to take a channel from a user, and prevent him from reentering the
channel or gaining operator status in the channel. The first thing you need to
do is to get ops. Here are 4 ways to get ops: 1. Via a NetSplit. (might take
a lot of time) 2. Asking one of the ops to let you be an op (Who knows? You
might get lucky). 3. Running a bot on your computer or on a shell account
and telling the other ops that it is online 24 hours a day, and ask them to op
it. They might do it, then tell the bot to op you. 4. You can always lure
the other ops into giving you op by telling them that you will advertise their
channel and bring them users and you might earn the ops status. You can do
nothing without the OP status. Here is what you do after you got an op and you
want to close they're channels: 1. First, mass de-op all the users so they
won't kick or ban you. There are a lot of scripts out there that will do this
for you. 2. Then place a ban on *!*@* 3. Mass-Kick the channel (also
with a script) 4. After this set the following modes: +smilk 1 1 (you type
/mode #Channel +smilk 1 1) 5. You took over the channel! :) There is a
problem with this, when you will leave the channel he will get empty and then
closed. The only solution for this is placing a 24/7 (24 hours a day, 7 days a
week) bot in the channel. If channel services are available on this network
(Like in DALnet), you can register the channel if no one else have done this
already. If you took over a registered channel, you will have a problem
keeping it because Channel Services can give the channel back to its legal owner
with no problem.
[How to completely ruin a channel] Here
are some possible ways to completely ruin a channel: 1) Turning the channel
into an invite-only channel, so only people who were invited (to invite people,
type /invite nick) can join. 2) Making the channel password-protected.
3) Making sure that you are the only OP in the channel and then turning the
channel into moderated mode and then mass-devoicing everyone. In moderated mode,
only voiced users (people with a little + in the beginning of their nick. To
voice people, do /mode #channel +v nick or -v to devoice) can talk. That way,
users will be able to see who is on the channel (note: you can see who's on a
channel without joining it by typing /names #channel), but they won't be able to
chat, and they will have to listen to you... :)
[Some expansion about RAW sessions] Too
lazy to read RFC ? Well, this is the "SUMMARY" of rfc1459 (IRC Protocol).
Hopefully after reading this you'll have better understanding of how the
protocol work (hey... don't just use it... try to understand how it work).
Yeah... this is also how some people spoof their IP by telneting from some
restricted shell account with no IRC client access.
[Connecting to the IRC daemon]
Telnet/netcat (yep... we're gonna use a raw socket) to the IRC port
(6667/6668..etc) of the IRC server.
eg <:> telnet irc.dal.net 6667
Send your nick & username to be recognized after u got connected using
the user command in this form
"user ".
eg <:> user nobody localhost localhost :I'm nobody nick nobody
-------------------------[!! NOTE !!]------------------------- At any
time if your receive anything like this ping :1234567 <-- The sequence
number change all the time or ping :192.0.0.1 <-- Some IP address
You must send back the number with a pong eg <:> pong :1234567
or pong :192.0.0.1
If you don't pong back, you'll be disconnected with a ping timeout error.
---------------------[!! END OF NOTE !!]-------------------
[Exploring some basic commands]
Ok, after the nick & user commands you can start chatting now. Type join
#channel (Without the /) to join #channel.
(Yea... most commands you use in your BitchX or mIRC client can also be
used here too...just don't include the / eg: part #channel quit :I'm
out etc... )
To send your message to a channel, use the privmsg command.
eg <:> privmsg #channel : Hi guys...Sup? (Dont forget the ":" if you
are going to send more then one word)
This will send "Hi guys...Sup?" to #channel
To send a private message to a user: eg <:> privmsg nickname : HI
ya
This will send "HI ya" to nickname.
To set a mode on a channel you simply type mode #channel mode. For
example, MODE #Channel +b 192.114.*.* will ban everyone that they're IP begin
with 192.114.
[Fun stuff to do]
If you get something like this ":nick!user@ip-address PRIVMSG your-nick
:_VERSION_" this means that nick is trying ctcp/version you. This command is
used to find out your version. Send the version back using the NOTICE
command... it could be anything you want.
eg : NOTICE nick :_VERSION Telnet version 0.1 :) _
This will send "Telnet version 0.1 :)" as the version reply.
[Faking /CTCP Replies]
Now many of you guys chat and have various people always doing{Client for
Client Protocol} CTCP replies, ie. VERSION, TIME, FINGER, PING
replies on you. These replies can get you in a lot of trouble, mainly its a way
for people to gather information about you then start up an attack. Now it
is time to change the replies your mirc will give in a way to cause the other
end to be fooled. Well this topic has been covered by many writers and warscript
developers, but many don't know about changing the replies to their advantage,
well look no further, here we go!
One of the most devistating attacks can come from a VERSION reply.
To do a ctcp version reply on a user, all you have to do is type:
"/ctcp <nick> VERSION " This will return the nick's irc client. Now
you may ask why is that important? Well lets say your using mirc 5.7x which
suffers from heap overflow of 217 bytes, and 5.8 heap overflow of 226
bytes by knowing your version an attacher already knows which operating
system your using and a version, so they can hack you without a trojan and you
won't know it happened. Lets kill the version reply to either give a fake
reply or no reply at all so they can sit there waiting, lol. Okay you will
need a hex editor for this, I recomment Hiew, get it here! -make a backup of your
mirc32.exe. -install hiew, load it up, once you have clicked mirc32.exe now
you will see some garbage, click F7 that should popup the search box, type in
VERSION you should be able to find the reply something like mIRC32 v5.8
K.Mardam-Bey. Now just delete the reply. If you have trouble doing it with Hiew
then get another hex editor, there are many around but its the best. So save and
exit. Now you can chose to have no Version reply to make your attacker suffer
from waiting when there isn't going to be a reply or you can fake your reply to
trick him. Lets trick the attacker:
Load up you mirc, then goto the tools menu, then click " Remote ".
There you should see a box, now simply write this mini script,
ctcp 1:VERSION:{
.notice $me Recieved CTCP VERSION from
$nick $+ / $+ $site ctcpreply $nick VERSION "write your reply here, make
it funny" | halt } | So now we
have faked our ctcp reply it should look like this, if we faked it to have no
reply
/ctcp Mikkkeee VERSION
-> [Mikkkeee] VERSION - [Mikkkeee VERSION] -
Well now the attacker will keep waiting and waiting.
Lets fake some more, Another ctcp reply that can be of usage is /ctcp
<nick> PING This reply of your ping will tell the attacker the
speed of your connection and if your lagging, wink wink he might want to do a
dos attack and boot you, so lets fake the reply to our advantage. Same as
above write this mini script in our tools, then "remote"
ctcp 1:PING:{
ctcpreply $nick PING "your pings
number in sec" | halt } | Usually I
have mine set to 1 sec , but you can make it funny like 690263165 sec, which
would leave the attacker fooled/confused.
Another reply that can cause you a bit of harm is /ctcp <nick >
TIME which will send the other user, your local time/date. This is very
bad cause if your busy trying to bounce your ip over wingates and proxys and now
your ip is somewhere in Asia, and someone does ctcp TIME then they will know
your true location in the world, which can hurt your spoofing tricks.
So lets fake it to our advantage!
ctcp 1:TIME:{
ctcpreply $nick TIME "your new
time" | halt
} | your new time can be
something like, Tue Jun 12 22:23:17 1989 be creative!
Another ctcp reply that can be used to gather some info on you is /ctcp
<nick> FINGER its not a big deal but it simply replies what you have
told it to reply, so just fake everything. hope that helps!
[How to spoof via https proxys]
Now this idea is very creative, and I just found a little program that you
can use to do it. It is called ThroughTheFire 0.9 which is able to
spoof your ip via https proxys. It is a new innovation in spoofing, lol !You can
also use this program to spoof telnet and i guess ftp sufing. Well all you have
to do now is find working https proxy lists. To do so just type in ww.altavista.com +"Https proxy" and you
should get some results, maybe not working results. Read the Search Engines Ripped Apart
tutorial to see other methods on using search engines.
[War Scripts] War scripts are usually
scripts for IRC clients that contain features like Mass DEOP / Kick, channel
takeover options, nukers, flooders, clones and sometimes bots. Some scripts even
contain some nice and funny features that don't necessarily have something to do
with IRC Warfare.
In this section I will briefly cover some of the more known war scripts and
their features.
7th Sphere Script (c) 1996-1997 7th Sphere Enterprises
Support@7thSphere.com - http://www.7thSphere.com Pros: Easy setup, Nice
protections, Automatically runs the Click nuker and fills-in all the needed
values. Cons: Protections are not customizable enough. Channel Takeover
doesn't mass kick / ban the channel.
TRiBE (t7) By
kefz(tribe) Pros: Excellent protections, Excellent socket flood clones and
firewall flood clones. The best I have ever seen! Comes with a great set of
utilities. Can automatically run click with all the options pre-configured.
Excellent set of scripts / clients / bots exploits / backdoors. Cons: None!
Go get this script now!
Peace and Protection 4.0
Pros: Get it and see for your self, simply a work of art! Cons: Too many
good tools, lol
Wang Script 3.5
pro Pros: Wang Clone, Trojan scan, Password protection, nickname find,
ctcp masking, email checking/sending, clone scanner, anti takeover, info finder,
takeover, fake dcc's, telnet, wartools addons. Cons: NONE!
[Editorial - IRC wars, another
perspective] Note: Most of this is taken from an article that was
written by Ntd (ntd@mirc.net). I feel that this article has the best perspective
about the IRC wars. Note 2: If you are a newbie and you think IRC wars are a
great form of hacking, and doing complex attacks you might want to skip this
chapter and read it another time.
IRC WAR? A LOAD OF SILLY NUKES Right, first things first, nukes -
or properly, Denial of Service (DoS) attacks - are technically nothing to do
with IRC war. They operate directly from the attacker to the victim's IP, and
IRC comes into it only inasmuch as it gives the attacker a ready source of IP
addresses to attack, and perhaps a "motive" for doing it (e.g, "they banned
me!"). But, attackers could just as easily collect IPs from services such as ICQ
(which, incidentally, has to be one of the most idiotically insecure protocols
ever invented, yet many people who bemoan IRC attack happily run ICQ, and
probably don't even check the option to hide their IP which is useless anyway
because there are lot of patches that will always show you the IP even if the
user chose to hide it).
IRC WAR DOESN'T HELP IMPROVE SECURITY Surely the stupidest
argument against IRC war, is that unlike other forms of hacking, it does not
help anybody because it doesn't contribute to increased security. There is a
mass of evidence showing quite clearly that this is not the case. Why did
Microsoft release a winsock that was not vulnerable to the port 139 OOB nuke?
Because that nuke became so widely abused. Why do current versions of mIRC have
an option to only enable the identd server during connection? Because mIRC 5.3
had an ident exploit with which mIRC could be crashed. Why, in fact, have flood
attacks become so obsolete? Because ircds now contain anti-flood code written
directly in response to flood abuse. Of course these attacks are irritating and
disruptive at the time, but in the long term they have undoubtedly led to more
secure code in operating systems, clients and irc daemons.
IRC WAR IS NOT REAL HACKING Again, this stems from a
misunderstanding of what IRC war is. Essentially there are two types: TCP/IP
attacks (ICMP nuke, smurf, fraggle, ping of death) and ircd based attacks (nick
collisions, lag collisions, serverops, hacking o:lines, bogus bans). While the
first category are almost exclusively "lame cracking" (that is, the user needs
only to download a program and can then use it without any actual knowledge),
the second category is more ambiguous. I know one person who finds many exploits
by working with the ircd code (which is of course almost always free for
download) - and finding bugs by working with the source is as "real" as hacking
can get. Within a few days of their implementation he found ways of bypassing
the ircnet ircd patches designed to protect against open socks servers and
deliberate nick collisions. He even found a method by which a normal client
could completely crash a server remotely. And what did he do with this
knowledge...?
DOS ATTACKS Yes, they are illegal, and yes they are disruptive.
Furthermore, many DoS attacks affect many more people than those targeted, the
most obvious example being the smurf attack. I am one of a group of friends who
run a few of the biggest channels on ircnet, and these channels are regularly
attacked by war groups intent on taking them. I make no exaggeration when I say
that several times a week, if not everyday, members of the original channel
opers complain that they are being smurfed by members of groups attempting to
take the channel. These smurf attacks are capable of taking down entire ISPs and
that IRC warriors recklessly use these attacks against single users just to take
an irc channel is utterly inexcusable in my opinion.
MOTIVATION While there are some IRC warriors / hackers like the
individual I described above, it is sadly true that there are many more who are
acting from more dubious motives. To the people who resort to floods, nukes and
such tools just because they are banned from channels, I say: you need to get
out more. What, then is my basic point? My conclusion is that IRC abuse and
hacking is like any other branch of hacking - it ranges from the incredibly
basic and lame to the actually quite skilled and beneficial. At the one end are
the classic 13 year old hax0r wannabes with their CLICK.EXE, and I am in no way
suggesting these people's behaviour should be excused or tolerated. However, I
urge you all to be aware that at the other end of the scale exist talented,
knowledgeable hackers discovering and revealing bugs in clients, OSes and ircds
by a variety of methods and in doing so making IRC more secure for all of us.
[Some intresting articles by Packet]
=[Ping Flooding]=
1. =What is a ping?= A ping is a small file (often 32 bytes) that is sent
to another computer online, in which the other computer replys. Basicly it
is saying "hello" to another computer. With this is also shows how long it
took for the ping to get there and back.
2. =So why is this usefull to me?= Well it can and it can not be usefull.
If you are going to play a game like quake/quake2 on a server, the faster
the ping gets there and back the better. Also, if you are on a fast
connection you can nock people of there ISP temperarily. This is called ping
flooding, and can work very well. The best thing to flood with is a T1 or
better. Even if you don't have more than a 28.8 you can lag or kill someone.
Here is an example of how ping works
C:\ping 24.131.12.124
this would send a few 32byte packets to that host. Now, this won't do much
by itself...but there are more features to pinging that make it very
usefull. this is the command I often use
C:\ping -l 2800 -t -w 2000 24.131.12.124 (good for 28.8 users)
-l is the size of the packet to send, generaly you want to keep trying higher
numbers till you find the very most there connection can take....soon they
will be to lagged to do much, or get killed. -w is how long it waits till it
decides to time out.... -t keeps pinging the IP untill you hit CTRL+Break
there are some other cool switches like -n wich echo floods them, and -v
witch specifys the Terms Of Service
=[Net Splits]=
1. =[What is a NetSplit]= The large irc servers work, is they link
together to provide less lag and a local server to many people. They link
together so that people can talk and do what ever and not have to be on the
same server. What a netsplit is, is when one server is lagged enough it
breaks off from the rest of the servers then becoming its own stand alone
server untill it merges again.
2. =[Why Does this matter?]= Well it can and it can't matter....It is
possible to take over a channel through netsplits. So it can matter if you
want to protect yourself from this, or do it yourself.
3. =[How do I protect myself?]= The only way is to have netsplit
protection. Alot of people do not like this script, and I do not recomend
using it unless you think someone is trying to take your channel. When
servers merge it trys to restore the settings as it was before the split. So
if you were a channel operator the server would OP you, reset the modes etc
etc. When someone takes a channel by a netsplit they get opped by the
server, so the script deops anyone who is opped by the server. If you do use
this script, make sure people can op themselves automaticly by sending you a
message. ...
4. =[How do I take a channel through this?]= First you need a link
looker, (which comes with this script). What a link looker does is search
for servers that are about to or have broken off. When you find a server
that has broken off, you need to quickly join that server and go into the
channel you want to take over. If no one else is on that server you will be
a channel operator. But this is not all you have to do, because when the
servers merge again it will deop you. You need to run the Dysnch script
which will fill the channel with bans and diffrent modes. Hopefully it will
screw up the already screwed channel enough that when the merge happens it
thinks you were a channel operator and you keep your OPS. Then you need to
quickly run the takeover script so that none of the netsplit protection (if
there are any) scripts deop you.
=[Advanced Nuking]=
Nuking is fun for the whole family, but sometimes it's not just "wham bam
thank you ma'am". On occasion, it requires you to be a little creative to
successfully nuke someone. hopefully we will give you some ideas on how to
become a pheared nuker.
** Open ports: In order to become a successful nuker, you must learn to
find as much information about your target as possible. One of the most
important elements to nuking is finding the right ports to nuke. the default
IRC server ports are 6660-6669, with 6667 being the most commonly used. One
thing you may discover throughout your nuking 'career' is that most servers
offer different ports that are open for IRCing. The easiest way to find out
the open ports is to check the Message Of the Day, for 90% of all IRC
servers will list their open ports in the motd. To get the message of the
day simply type '/motd irc.server.net'. This will display the motd and allow
you to find the open ports (usually). Now you can nuke these ports,
increasing your chances of success.
** Their Connection: Another thing you may want to do is find out whether
your target is on a shell account, or a dial-up account. Under normal
circumstances, dial-up users are easier to nuke then shell accounts for
reasons we won't go into right now. To find out which they are using, simply
take the last part of their IP and try to visit to the ISP's homepage.
Again, there are many servers that will describe their services on their
web-page. Usually, if their ip is two or three legible words only interupted
by a period, then it is a shell. For instance,
"jkrondike@mainsys.postex.net" would most likely be a shell account, while
"yourmom@modem29.er.actil.net" is usually a dial-up.
** Nuking Shell Users: If you're using windows, you should download a
program that will allow you to finger a server. Cyberkit is a good program,
for it has Ping, Finger, Traceroute, etc. get it at
http://www.ping.be/cyberkit/cyber.zip, or go find one of your own. there are
hundreds to choose from. (no we're not being endorsed by cyberkit, it's just
a kickass proggie) Most shell account users will login from a dial-up
account, and if finger is running on their shell, it should display the
dial-up IP address. Finger the server and once you know this, use your nuker
to disconnect them from their shell by replacing the IRC server with their shell
account address, and use the IP you found through finger as the client. Use
ports 22 24 as the server ports, in place of 6660 6669. Port 23 is the
default telnet port, so nuking from 22 to 24 will effictivly disconnect them
from their shell account. this usually causes your target to quit irc with
"Where did my controling terminal go?" quit message. it's pretty funny when it
works.
