Abstract : In this project we try to hack network by scanning IP address and port number Of rem remote ote comp comput uter er,, with with the the help help of that that we try try to hack hack remo remote te computer computer . we will send remote remote computer computer our executable executable along with PDF file through E-mail , Executable code contain contain IP address scanner scanner ,Port number number scanner ,Email ,Email sender, And Trojan Horse .when user of remote computer click on PDF file then executable code will activate and do following thing 1. IP address address and Port Port number number scanner scanner will will scan scan IP addre address ss and port number Of remote computer and send it back to us through e-mail. 2. Trojan Trojan Horse that that is actually actually a client server server program program in which which server server program run on remote computer and client program run on hacker computer and with help of IP address and port number we try to connect Our client program to server program.

INTRODUCTION "Hacking" is, basically, unauthorized access to a computer or network. It could be the unapproved use of one system to gain access to another system , and it could also mean simply entering a specific computer or network without permission. Simply blocking or disrupting access to a computer/server is not "hacking". In this technology driven world where everything is technology based our afford is with the help of that technology to heck network and with the help of that to hack remote computer attached to network using IP address Scanner ,Port Number scanner , E-mail sender and Trojan horse With the help of this application we can hack network, remote computer and any device available on network like pen-derive, mobile, PDA. etc This area is important because we can use this application to ensure security of our country and network system and can monitor network traffic to detect network intrusion . We can use this application to hack other country computer and we can access sensitive information from that remote computer. We can also use this application to hack terrorist network and can get information about terrorist activity, plan so that we can take proper action at a proper time to fail terrorist plan so that we can save lot of life
DESCRIPTION OF THE WORK
(a) Background / Technical Description We complete our project using the java technology. (b)Design description . Attacker will send PDF file along with his active code .when user of remote computer will click on that PDF file the code will be activated and trace IP address and port number of remote computer .And Email sender program will send e-mail back to the attacker ,with the help of that IP address and port number Attacker will ping using IP and Port number to know that whether user is alive , if that person is will alive than he will established connection with that computer and execute desired command.
(a) New contributions / How this work will add to the existing literature?
We create a program E-mail sender when user of the remote computer will click on the remote file that active code on that file trace IP address and Port number of remote computer send it back to the hacker .
IMPLEMENTATION DETAILS (a) Experimental setup / Hardware & software requirements.
1. Software –Net Beans , windows
2. Hardware- computer , processor . (b)Other requirements for execution of the task Nothing.
OBSERVATIONS & RESULTS (a) Observations & Results - Output of programs/screenshots, tables, graphs etc -

Analysis. we run our network hacking program in two different machine connected to the network ,then with the use of the IP address and port number we successfully get access to the remote computer .we execute command like to excess remote computer directory , to know what operating system running on remote computer and to download file from remote computer to our computer. And we successfully execute all command .
CONCLUSIONS To hack network, necessary thing is to trace IP address and port number of remote computer. Once you get IP address and port number ping remote computer using IP address. With the help of this project we get success to trace IP address and port number of remote computer, with the help of that IP address and port number of remote computer we successfully connect our client program to the remote computer server program that we had send along with the PDF file through E-mail. Now we successfully connect our computer to the remote computer. We then successfully execute all Command which we implement in our application. Like 1. To know remote computer operating system name and version, and remote machine time.
2. 3. 4. 5.
Get access to the directory. Make directory in the remote computer. To download file from remote computer to our computer. Delete file from remote computer.
FUTURE DIRECTIONS (a)What you could not attempt in this project (due to shortage of time, lack of resources / prior expertise in this area, unavailability of literature etc.). Due to the shortage the time and lack of the resource we could not attempt Following thing 1. Install software from our system to the remote system 2. Download video from our system to remote system, and vice versa 3. Fetch large file from remote system 4. to corrupt remote computer operating system, hard disk. (b)What more can be done in this area if time / resources / technical knowhow are available or provided to you. (c) Network hacking is the area in which lot of thing can be done if we have resource and technical knowledge, like 2. Install software from our system to the remote system 2. Download video from our system to remote system, and vice versa 3. Fetch large file from remote system 4. To corrupt remote computer operating system, hard disk. 5. When we send PDF file to remote computer along with active code then we want to get access to the remote computer email account so that we can get access to his inbox out box ,and want that we can sent e-mail from his account to another person.
(d)What more can be done by other groups wishing to work in this area.
Up to our knowledge and within this sort time we try our best, but feature which we cannot implement .we wish from some other group to implement that Feature to make project more powerful. like. 3. 2. 3. 4.
Install software from our system to the remote system Download video from our system to remote system, and vice versa Fetch large file from remote system to corrupt remote computer operating system, hard disk.
