How to Hack A Facebook Account

 How to Hack A Facebook Account

 And How To Protect yourself From Hackers

Please take note that this is for educational purposes only and
not to be used as a means to scam or attack other facebook
users.  The reason I am sharing this is because I want you to be
aware that your FB account can be hacked and how you can
protect yourself from it.  Also, there are so many fake so-called
“hacking tools” that are actually coded to appear as if it is
attacking and retrieving facebook passwords from an email you
provide.  But in reality, it is impossible to hack facebook
directly.  Meaning a simple visual basic program (usually used by
wanna be hackers) cannot, in any way, penetrate the highly
secured database of facebook.  I can easily write those fake
programs in less than 2 minutes and it would appear to be real
but is only doing some visual effects to let the user believe it is
hacking facebook.

There are other ways however that a facebook account may be
hacked, and your account is no exception.  This includes some
clever program that retrieves all passwords and emails from a
specific computer.  This kind of program is most effective when
used in public computer shops like public internet cafes or
public libraries and similar places. You simple run the program
and it retrieves all files logged in to facebook.  

That why it is most advised to avoid using your facebook account
especially in public places where one computer is used by
several persons in one day.  If you really feel the need to open
your account in such places, make sure to run a keylogger
detector program.  Then you must always clear the browser
cookies before logging in and after logging in to your facebook
account.

You can download a sample program here

Keylogger Detector program (small file that you can upload to your

email and download it whenever you need to use it in a public internet café or public library)

Aside from protecting your FB account, keylogger also protects
all your email login details.  Not to mention your login info to
your favorite online games

The other trick to hack a facebook account is through the use of
a fake login page.  Here is a sample email that you might
receive from a hacker:

Body: 

Dear facebook user (victim's facebook user name), 

Recently we saw some suspicious activity on your account, we  

suspect it as a malicious script. As a valuable user to us we  

understand   this   might   be   system   error,   if   the   activity   is   not  

generated by you then please log-in to your account by followin                 

link, 

<link to fake login site> 

Failing to log-in within next 48 hours Facebook holds right to  

suspend your account for sake of privacy of you and others. By  

lo   ing in you'll confirm it is system error and we will fix it in no  

time. Your inconvenience is regretted. Thank you. 

support@facebook.com,  

Facebook, Inc, 

1601 S.California Ave 

Palo Alto CA 94394 

US 

So in this email, a person that is not security conscious might  

quickly click on the link and login.  Unfortunately, the login link  

is not facebook.com/login.php but some other website.  That  

login details are then stored and your account compromised. 

An even trickier strategy is to share some scandal video on the  

wall that creates intrigue to friends, so convincing that they  

need to see that particular scandal.  The video however is only  

viewable upon share.  So when you are asked to log-in so that  

you can share the video, you are instead logging into a fake  

page that looks exactly like facebook interface and thus your log  

in details in the hands of the hacker. 

Download a sample script of this hacking program  

here 

So as a lesson, always make sure to check the browser bar  

whenever you are asked to login to your facebook account.  If  

the browser bar is not FACEBOOK.COM/LOGIN.PHP and some  

other site like OTHERSITE.COM/LOGIN.PHP, NEVER EVER login!  

So that your account details and your facebook account will not  

be hacked.

Tips for creating strong passwords and passphrases

 
    Tips for creating strong passwords and passphrases

A password is a string of characters used to access information or a computer. Passphrases are typically longer than passwords, for added security, and contain multiple words that create a phrase. Passwords and passphrases help prevent unauthorized people from accessing files, programs, and other resources. When you create a password or passphrase, you should make it strong, which means it's difficult to guess or crack. It's a good idea to use strong passwords on all user accounts on your computer. If you're using a workplace network, your network administrator might require you to use a strong password.


Note

•In wireless networking, a Wi Fi Protected Access (WPA) security key supports the use of a passphrase. This passphrase is converted into a key that is used for encryption, which is not visible to you. For more information about WPA security keys, see What are the different wireless network security methods?

What makes a password or passphrase strong?


A strong password:


• Is at least eight characters long.
• Does not contain your user name, real name, or company name.
• Does not contain a complete word.
• Is significantly different from previous passwords.
• Is 20 to 30 characters long.


A strong passphrase:


• Is a series of words that create a phrase.
• Does not contain common phrases found in literature or music.
• Does not contain words found in the dictionary.
• Does not contain your user name, real name, or company name.
• Is significantly different from previous passwords or passphrases.


Strong passwords and passphrases contain characters from each of the following four categories:

Character category         Examples

                       
Uppercase letters A, B, C
Lowercase letters a, b, c
Numbers                0, 1, 2, 3, 4, 5, 6, 7, 8, 9


Symbols found on the keyboard (all keyboard characters not defined as letters or numerals) and spaces
EXAMPLE:- ` ~ ! @ # $ % ^ & * ( ) _ - + = { } [ ] \ | : ; " ' < > , . ? /

A password or passphrase might meet all the criteria above and still be weak. For example, Hello2U! meets all the criteria for a strong password listed above, but is still weak because it contains a complete word. H3ll0 2 U! is a stronger alternative because it replaces some of the letters in the complete word with numbers and also includes spaces.

Help yourself remember your strong password or passphrase by following these tips:

•Create an acronym from an easy-to-remember piece of information. For example, pick a phrase that is meaningful to you, such as My son's birthday is 12 December, 2004. Using that phrase as your guide, you might use Msbi12/Dec,4 for your password.

•Substitute numbers, symbols, and misspellings for letters or words in an easy-to-remember phrase. For example, My son's birthday is 12 December, 2004 could become Mi$un's Brthd8iz 12124, which would make a good passphrase.

•Relate your password or passphrase to a favorite hobby or sport. For example, I love to play badminton could become ILuv2PlayB@dm1nt()n.


 If you feel you must write down your password or passphrase to remember it, make sure you don't label it as such, and keep it in a safe place.

   Creating stronger passwords and passphrases using ASCII characters


You can also create passwords and passphrases that use extended ASCII characters. Using extended ASCII characters helps make your password or passphrase more secure by increasing the number of characters you can choose from to make it strong. Before using extended ASCII characters, make sure that passwords and passphrases containing them are compatible with the programs that are used by you or your workplace. Be especially cautious about using extended ASCII characters in passwords and passphrases if your workplace uses several different operating systems or versions of Windows.

You can find extended ASCII characters in Character Map. Some extended ASCII characters should not be used in passwords and passphrases. Do not use a character if a keystroke is not defined for it in the lower-right corner of the Character Map dialog box. For more information, see Using special characters (Character Map): frequently asked questions.

Windows passwords can be much longer than the eight characters recommended above. In fact, you can make a password up to 127 characters long. However, if you are on a network that also has computers running Windows 95 or Windows 98, consider using a password that is no longer than 14 characters. If your password is longer than 14 characters, you might not be able to log on to your network from computers running those operating systems.
