But before I give you access to the eBook, first you must know what Batch File Programming is.

Batch files are essentially sequences of DOS commands stored in a text file with an extension of “BAT”. When run, the batch executes each line in the batch file as if they were typed in at the console. So basically, a file containing DOS commands that you normally type into the command prompt.

Batch file are mainly used to do repeat tasks. Instead of typing in a commands over and over again to do a certain task, you can create a batch file that does it all automatically by performing a bulk set of commands.

So why should hackers know batch programming? Well I’ll give you a few ideas and you can decide on your own:

Attacks

• DNS Poisoning
• Packet flooders
• Dictionary attacks
• Creating Viruses
• Service Disabler
• Clearing Logs

Annoyance

• Bombers (Fork, Broadcast)
• Msg Annoyers
• Flooders (user, folders)
• Extension changer (ex. html -> exe)
• Keystroke remapper

There are so many more annoyances but I’m getting annoyed just from listing them. But I bet you get the point.. so lets get to the good stuff, no not drugs you bum. Click the image to download it.

Let me know what you think .

A hub and a switch have the same purpose; to connect a bunch of computers via ethernet “cross over” cables to create a network. Their main difference is that a switch is much more intelligent than a hub.

On a hub, all of the internet traffic (packets) are sent to every connected computer, where it is determined whether it belongs to that computer. As you may have already guessed, this isn’t very bandwidth friendly and is bad for performance.

Switches are much smarter, they are able to inspect all the headers of the packets coming in and determine where they are coming from and to whom they are destined for. The switch then forwards the traffic to the proper destination. This greatly reduces bandwidth and offers much better performance. For this reason you won’t find many hubs these days, switches are the preferred choice for networks for obvious reasons.

Because all traffic is forwarded to all the machines on a hub, it is very easy to sniff and store the traffic since it just comes to you. The sniffed packets may include website passwords, ftp passwords, the websites the user visits and other personal information.

On a switch, since the traffic is examined and forwarded to the correct machine, how would you sniff it if it doesn’t come to you? Easy, by ARP spoofing. Watch out for a post on that very soon.

then you know it is disabled for your user level.

To get a COMMAND.COM prompt up, open Notepad.exe and type in “command.com” without the quotes. Next, save it as a batch file via the “.bat” extention. So save it as “anything.bat” . Now once you double click this file, you should get a functional command prompt if it isn’t disabled.
