i know dis is lame but just would like to share wid u.
have nothing for next half an hour so typing it.. lol


here are many ways to defeat java-script protected websites. Some are very simplistic, such as hitting
[ctl-alt-del ]when the password box is displayed, to simply turning offjava capability, which will dump you into the default page.You can try manually searching for other directories, by typing the directory name into the url address box of your browser, ie: you want access to www.target.com .

Try typing www.target.com/images .(almost ever y web site has an images directory) This will put you into the images directory,and give you a text list of all the images located there. Often, the title of an image will give you a clue to the name of another directory. ie: in www.target.com/images, there is a .gif named gamestitle.gif . There is a good chance then, that there is a 'games' directory on the site,so you would then type in www.target.com/games, and if it isa valid directory, you again get a text listing of all the files available there.

For a more automated approach, use a program like WEB SNAKE from anawave, or Web Wacker. These programs will create a mirror image of an entire web site, showing all director ies,or even mirror a complete server. They are indispensable for locating hidden files and directories.What do you do if you can't get past an opening "PasswordRequired" box? . First do an WHOIS Lookup for the site. In our example, www.target.com . We find it's hosted by www.host.com at 100.100.100. 1.

We then go to 100.100.100.1, and then launch Web Snake, and mirror the entire server. Set Web Snake to NOT download anything over about 20K. (not many HTML pages are bigger than this) This speeds things up some, and keeps you from getting a lot of files and images you don't care about. This can take a long time, so consider running it right before bed time. Once you have an image of the entire server, you look through the directories listed, and find /target. When we open that directory, we find its contents, and all of its sub-directories listed. Let's say we find /target/games/zip/zipindex.html . This would be the index page that would be displayed had you gone through the password procedure, and allowed it to redirect you here.By simply typing in the url www.target.com/games/zip/zipindex.html you will be onthe index page and ready to follow the links for downloading.

3. TROJAN ATTACK THROUGH HTML

This was a normal html code which would create a simple webpage.

Now what you have to do is,
the server file of your trojan you will have to upload it on some webhosting and then change the link of the server file in the code and then save this code as "index.html" and then upload it to the same host.

All done, now everytime someone opens that webpage they would be infected with your trojan's server :)

4. dos attacks or denial of services attack

dos attacks or denial of services attack have become very common amongst hackers
who use them as a path to fame and respect in the underground groups of the
internet. denial of service attacks basically means denying valid internet and
network users from using the services of the target network or server. it
basically means, launching an attack, which will temporarily make the services,
offered by the network unusable by legitimate users.
in others words one can describe a dos attack, saying that a dos attack is one
in which you clog up so much memory on the target system that it cannot serve
legitimate users. or you send the target system data packets, which cannot be
handled by it and thus causes it to either crash, reboot or more commonly deny
services to legitimate users.
dos attacks are of the following different types-:
those that exploit vulnerabilities in the tcp/ip protocols suite.
those that exploit vulnerabilities in the ipv4 implementation.
3 there are also some brute force attacks, which try to use up all
resources of the target system and make the services unusable.
before i go on with dos attacks, let me explain some vulnerabilities in tcp/ip
itself. some common vulnerabilities are ping of death, teardrop, syn attacks and
land attacks.
ping of death
this vulnerability is quite well known and was earlier commonly used to hang
remote systems (or even force them to reboot) so that no users can use its
services. this exploit no longer works, as almost all system administrators
would have upgraded their systems making them safe from such attacks.
in this attack, the target system is pinged with a data packet that exceeds the
maximum bytes allowed by tcp/ip, which is 65 536. this would have almost always
caused the remote system to hang, reboot or crash. this dos attack could be
carried out even through the command line, in the following manner:
the following ping command creates a giant datagram of the size 65540 for ping.
it might hang the victim's computer:
c:\windows>ping -l 65540
teardrop
the teardrop attack exploits the vulnerability present in the reassembling of
data packets. whenever data is being sent over the internet, it is broken down
into smaller fragments at the source system and put together at the destination
system. say you need to send 4000 bytes of data from one system to the other,
then not all of the 4000 bytes is sent at one go. this entire chunk of data is
first broken down into smaller parts and divided into a number of packets, with
each packet carrying a specified range of data. for example, say 4000 bytes is
divided into 3 packets, then:
the first packet will carry data from 1 byte to 1500 bytes
the second packet will carry data from 1501 bytes to 3000 bytes
the third packet will carry data from 3001 bytes to 4000 bytes
these packets have an offset field in their tcp header part. this offset field
specifies from which byte to which byte does that particular data packet carries
data or the range of data that it is carrying. this along with the sequence
numbers helps the destination system to reassemble the data packets in the
correct order. now in this attack, a series of data packets are sent to the
target system with overlapping offset field values. as a result, the target
system is not able to reassemble the packets and is forced to crash, hang or
reboot.
say for example, consider the following scenario-: (note: _ _ _ = 1 data packet)
normally a system receives data packets in the following form, with no
overlapping offset values.
_ _ _ _ _ _
_ _ _
(1 to 1500 bytes) (1501 to 3000 bytes)
(3001 to 4500 bytes)
now in a teardrop attack, the data packets are sent to the target computer in
the following format:
_ _ _ _ _ _
_ _ _
(1 to 1500 bytes) (1500 to 3000 bytes)
(1001 to 3600 bytes)
when the target system receives something like the above, it simply cannot
handle it and will crash or hang or reboot.
syn attack
the syn attack exploits tcp/ip's three-way handshake. thus in order to
understand as to how syn attacks work, you need to first know how tcp/ip
establishes a connection between two systems. whenever a client wants to
establish a connection with a host, then three steps take place. these three
steps are referred to as the three-way handshake.
in a normal three way handshake, what happens is that, the client sends a syn
packet to the host, the host replies to this packet with a syn ack packet. then
the client responds with a ack (acknowledgement) packet. this will be clearer
after the following depiction of these steps-:
client --------syn packet-------------- � Host
in the first step the client sends a syn packet to the host, with whom it wants
to establish a three-way connection. the syn packet requests the remote system
for a connection. it also contains the initial sequence number or isn of the
client, which is needed by the host to put back the fragmented data in the
correct sequence.
host -------------syn/ack packet----------� Client
in the second step, the host replies to the client with a syn/ack packet. this
packet acknowledges the syn packet sent by the client and sends the client its
own isn.
client --------------ack-----------------------� Host
in the last step the client acknowledges the syn/ack packet sent by the host by
replying with a ack packet.
these three steps together are known as the 3-way handshake and only when they
are completed is a complete tcp/ip connection established.
in a syn attack, several syn packets are sent to the server but all these syn
packets have a bad source ip address. when the target system receives these syn
packets with bad ip addresses, it tries to respond to each one of them with a
syn ack packet. now the target system waits for an ack message to come from the
bad ip address. however, as the bad ip does not actually exist, the target
system never actually receives the ack packet. it thus queues up all these
requests until it receives an ack message. the requests are not removed unless
and until, the remote target system gets an ack message. hence these requests
take up or occupy valuable resources of the target machine.
to actually affect the target system, a large number of syn bad ip packets have
to be sent. as these packets have a bad source ip, they queue up, use up
resources and memory or the target system and eventually crash, hang or reboot
the system.
land attacks
a land attack is similar to a syn attack, the only difference being that instead
of a bad ip address, the ip address of the target system itself is used. this
creates an infinite loop between the target system and the target system itself.
however, almost all systems have filters or firewalls against such attacks.
smurf attacks
a smurf attack is a sort of brute force dos attack, in which a huge number of
ping requests are sent to a system (normally the router) in the target network,
using spoofed ip addresses from within the target network. as and when the
router gets a ping message, it will route it or echo it back, in turn flooding
the network with packets, and jamming the traffic. if there are a large number
of nodes, hosts etc in the network, then it can easily clog the entire network
and prevent any use of the services provided by it.

http://www.cert.org/advisories/ca-98.01.smurf.html
udp flooding
this kind of flooding is done against two target systems and can be used to stop
the services offered by any of the two systems. both of the target systems are
connected to each other, one generating a series of characters for each packet
received or in other words, requesting udp character generating service while
the other system, echoes all characters it receives. this creates an infinite
non-stopping loop between the two systems, making them useless for any data
exchange or service provision.
distributed dos attacks
dos attacks are not new; in fact they have been around for a long time. however
there has been a recent wave of distributed denial of services attacks which
pose a great threat to security and are on the verge of overtaking
viruses/trojans to become the deadliest threat to internet security. now you
see, in almost all of the above tcp/ip vulnerabilities, which are being
exploited by hackers, there is a huge chance of the target's system
administrator or the authorities tracing the attacks and getting hold of the
attacker.
now what is commonly being done is, say a group of 5 hackers join and decide to
bring a fortune 500 company's server down. now each one of them breaks into a
smaller less protected network and takes over it. so now they have 5 networks
and supposing there are around 20 systems in each network, it gives these
hackers, around 100 systems in all to attack from. so they sitting on there home
computer, connect to the hacked less protected network, install a denial of
service tool on these hacked networks and using these hacked systems in the
various networks launch attacks on the actual fortune 500 company. this makes
the hackers less easy to detect and helps them to do what they wanted to do
without getting caught. as they have full control over the smaller less
protected network they can easily remove all traces before the authorities get
there.
not even a single system connected to the internet is safe from such ddos
attacks. all platforms including unix, windows nt are vulnerable to such
attacks. even macos has not been spared, as some of them are being used to
conduct such ddos attacks.
end of dos attack....

How to crash a computer in less than 20 secs:
open a text document and put this in it:
@ECHO OFF
:loop
start cmd.exe
goto loop
Save this as test.bat on a safe place. Run it and the computer will crash. Put it in the StartUp
