How to Bypass CYBEROAM

TECHNIQUES TO BYPASS OR HACK CYBEROAM

USE TOR

• Download TOR Browser
• Install or Extract TOR browser in a portable USB drive.
• Plug your USB drive in computer and start TOR browser and start surfing on Internet, Now all websites like FACEBOOK, ORKUT, BLOGGER are accessible.

CACHED HACK

This HACK work for all blocked websites. You can easily open blocked websites using this technique. When you search anything using google In the each search result there are two things in blue color prior to URL i.e Cached and Similar. To view that blocked Website You have to click on Cached Click on CACHED to access blocked websites.

PING HACK

There are millions of Proxy websites available on Internet. Find non popular proxy websites to open blocked websites. Then follow these steps

• Start Command Prompt.
• Type Ping www.proxywebsite.com
• Copy IP address of that proxy website and paste into on you browser.
• Your blocked website will be unblocked.

Note : Try to find non popular proxy website, there are lots of proxy websites available on Internet and not be able to cyberoam block all proxy websites from Internet so this hack will surely work if you find non popular proxy website which make fool to cyberoam.

HTTPS HACK

Try to find proxy website that uses https i.e. SSL proxies are also not blocked by any Cyberoam.

What is Denial Of Service (DoS) Attacks ?

Denial Of Service (DoS) Attacks

A denial of service (DoS) attack is an attack that clogs up so much memory on the target system that it can not serve it’s users, or it causes the target system to crash, reboot, or otherwise deny services to legitimate users.There are several different kinds of dos attacks as discussed below:-

Ping Of Death

The ping of death attack sends oversized ICMP datagrams (encapsulated in IP packets) to the victim.The Ping command makes use of the ICMP echo request and echo reply messages and it’s commonly used to determine whether the remote host is alive. In a ping of death attack, however, ping causes the remote system to hang, reboot or crash. To do so the attacker uses, the ping command in conjuction with -l argument (used to specify the size of the packet sent) to ping the target system that exceeds the maximum bytes allowed by TCP/IP (65,536).
example:- c:/>ping -l 65540 hostname
Fortunately, nearly all operating systems these days are not vulnerable to the ping of death attack.

Teardrop Attack

Whenever data is sent over the internet, it is broken into fragments at the source system and reassembled at the destination system. For example you need to send 3,000 bytes of data from one system to another. Rather than sending the entire chunk in asingle packet, the data is broken down into smaller packets as given below:
* packet 1 will carry bytes 1-1000.
* packet 2 will carry bytes 1001-2000.
* packet 3 will carry bytes 2001-3000.
In teardrop attack, however, the data packets sent to the target computer contais bytes that overlaps with each other.
(bytes 1-1500) (bytes 1001-2000) (bytes 1500-2500)
When the target system receives such a series of packets, it can not reassemble the data and therefore will crash, hang, or reboot.
Old Linux systems, Windows NT/95 are vulnerable.

SYN – Flood Attack

In SYN flooding attack, several SYN packets are sent to the target host, all with an invalid source IP address. When the target system receives these SYN packets, it tries to respond to each one with a SYN/ACK packet but as all the source IP addresses are invalid the target system goes into wait state for ACK message to receive from source. Eventually, due to large number of connection requests, the target systems’ memory is consumed. In order to actually affect the target system, a large number of SYN packets with invalid IP addresses must be sent.

Land Attack

A land attack is similar to SYN attack, the only difference being that instead of including an invalid IP address, the SYN packet include the IP address of the target sysetm itself. As a result an infinite loop is created within the target system, which ultimately hangs and crashes.Windows NT before Service Pack 4 are vulnerable to this attack.

Smurf Attack

There are 3 players in the smurf attack–the attacker,the intermediary (which can also be a victim) and the victim. In most scenarios the attacker spoofs the IP source address as the IP of the intended victim to the intermediary network broadcast address. Every host on the intermediary network replies, flooding the victim and the intermediary network with network traffic.
Result:- Performance may be degraded such that the victim, the victim and intermediary networks become congested and unusable, i.e. clogging the network and preventing legitimate users from obtaining network services.

UDP – Flood Attack

Two UDP services: echo (which echos back any character received) and chargen (which generates character) were used in the past for network testing and are enabled by default on most systems. These services can be used to launch a DOS by connecting the chargen to echo ports on the same or another machine and generating large amounts of network traffic.

Resetting Ubuntu 11.10 Password

If you’ve forgotten your Ubuntu 11.10 Password you can reset it within minutes. I will tell you two methods to reset your Ubuntu Password. The first one is by booting it in recovery mode and second one is by using any Live OS.

Let’s start with the recovery mode first as it takes less time and easy to do in comparison to the second one method:

Boot up your Ubuntu. Press and Hold ‘Shift’ Key while the machine is booting. You will get the GRUB Menu like this:



Select the second option which is ‘Recovery Mode’ and press Enter. After pressing enter system will start booting and you will get a list of options like this:



After that we need to make the filesystem writable so that we can change the password. To make it writable select the 3^rd option ‘remount’ and press Enter. After pressing enter you will get the following:



Press Enter here and you will get recovery menu with a list of options again:



Select the last option ‘root’ and press enter. If the root account password is not set then you will get a shell prompt like this:



Now you can enter commands to reset the password of any account.
#passwd <username>



Enter the new password and confirm it by entering again.
Now enter command ‘sync’.



Now Enter the command ‘reboot –f’ to reboot.



Now you can login with your new password.

Now if the root account is having a password then you will not get the shell at recovery mode. In this case you need to boot your ubuntu machine with any Live OS. I will be booting it again with Ubuntu 11.10.

Boot your machine with Ubuntu 11.10. You will get a screen asking to just try this as a live cd or install it on your machine:



Click on ‘Try Ubuntu’  to use it as a LIVE OS.

You will get desktop a live user.  Now you need to mount the file system to change the password. First we need to know the device name of the filesystem to mount. To get the name of device enter the command ‘sudo fdisk –l’



Now as you can see the system type of /dev/sda1 is Linux.
So we need to mount the device ‘/dev/sda1’.

To mount this device enters the following command.
#sudo mount /dev/sda1 /tmp



Now we need to enter the command ‘sudo chroot /tmp’  to get the shell on your filesystem:



Now we’ve got the shell we can change the password of any user by entering the command ‘passwd <username>’


Now restart the machine by entering the command ‘reboot’ and you will be able to login with your new password.
