Brute-force and dictionary attack, poor hacking tactics

April 29th, 2011 No comments

Mr. Das noticed that his boss entered a 5-6 digit password in his personal management project. Mr. Das noticed only 1st digit of the password. Next day he made all possible combination with 5-6 digits where the first digit was known. He used brute-force attacker software to generate and apply combination in less time. And he cracked the password.

A brute force attack means trying every possible combination until you find the right one.

You are free to customize input characters, password length. For example

For letters 1,3,a,t,u, some possible combinations would be

13atu

13aut

13tau

:

atu31

31tua

:

You can give input characters to limit number of words. You can also limit the length of password like if you keep password length 4 for above example then combination would be;

3au1

3ta1

:

dictionary attack is very similar to Brute-force attack. But it is little bit faster. It doesn’t make combination of input characters but uses dictionary word. This is somewhat like making anagram.

Why do I call it as poor hacking tactics?

A hacker never believes in Hit & Try. They search for a proper method. There is always some logic behind any step they take. I hacked locked folders and locked ZIP files too. But I never used any brute force attacker.

How to protect you from Brute-force and dictionary attack?

Never let anyone enter password many times nor enter password in other’s presence.

You can’t control people to enter password many times. But a programmer can do. Read below mentioned points which would help a programmer and user as well to avoid such attacks.

Programmer’s point of view

  • Lock the account after fixed number of failed login attempts.
  • Block an IP, where you get many failed login attempts from.
  • You may increase interval between two logins.
  • Don’t let user set password less than 6 or 8 length.
  • Ask users to set password containing alphanumeric & special characters.

User’s point of view

  • Password length must be more than 6-8 characters.
  • Your password must not be any dictionary word.
  • You must use alpha numeric & special characters in your password.
  • Don’t use password like your PAN# or mob# or something that can be guessed easily.
  • Change password regularly, once in a month or as per your choice.
These attacks fail breaking lengthy and stronger passwords.

Remember that brute force & dictionary attacks are not only the way to hack your password. The worst technique for users is keylogger and for programmer is SQL injection.

I hacked admin section of my site yesterday morning

October 14th, 2010 No comments

I generally use long password including all sort of characters.
Yesterday I forgot the password of admin section of my site. But I supposed to log in anyhow since I was unable to do any activity. I decided to hack it.
amty dice admin login key
Difficulties which were in front of me

  • I don’t use password which are common for multiple accounts. So it was very difficult to take idea from other passwords.
  • Generally all the passwords are 18 characters long. So it was very difficult to guess.
  • My password contains all alphanumeric characters and special symbol. There were total 1.1962222086548019456196316149566e+56 possibilities, if i try. So even the brute force attack was helpless.
  • I never use English dictionary word. So it makes dictionary attack disable. For some password I use Hindi dictionary word
  • If I enter wrong password one time then I would not be able to log in for next 15 mins even with correct password.
  • If I enter wrong password 3 times then I would not be able to log in for complete day.
  • SQL injections were effect less since I already had handled them somehow up to some level.
  • When I started to hack, I was supposed to break some internal security layers. And I had forgotten password for them as well.
  • But I hacked it….

    Of course I’ll not tell you how. But there is a hint. You can find out the way in my previously published four articles. All are interrelated. And only one of them is tagged for hacking. One of them is tagged for online services. and rest you need to find

    WordPress security hack

    September 16th, 2010 No comments

    Do you avoid people to get registered on your site? …… Many people do this because they afraid.

    There is common thinking in everyone’s mind that if you want to secure your wordpress blog then you must disable users to get registered on your site.


    amty wordpress security hack logo

    Registration on a site always attracts hackers. Many plug-ins may secure your blog. But some of them might be proved as a powerful & useful tool for hackers.

    Here I am discussing about a plug-in which is very useful in point of security. But I used this to hack my own site.

    Let’s do it.

    1
    Install wp file monitor plug-in. This plug-in monitors all files on your site. It prompts you if any file is manipulated by any hacker, virus or by any other utility. It prompts you even if you do any changes. It also can mail summary of changes.
    2
    Now register at your own site. And login as a subscriber. Remember that below steps shall not work until you log in.
    If you are testing this hack on your localhost then you must know, how to register users on local machine?
    3
    Now this is the time to hack your own site. Put following URL in address bar of any internet browser like Epic.

    
    http://localhost/wp-admin/options-general.php?page=WordPressFileMonitor&display=alertDesc
    
    or
    < your blog url >/wp-admin/options-general.php?page=WordPressFileMonitor&display=alertDesc
    

    My aim behind writing this post is not to improve hacking but to aware people.

    Here you’ll get a page informing you last modified files. You also can remove this information without any administrator permission. So the next time when owner of that site logins to dashboard, shall not be prompt for any modification. Only the problem is that if mail service for this plug-in is already enabled then the owner would be prompted via mails.

    This hack will help you to collect more information about the site like latest changes, posts in draft, plug-in recently installed, theme, and various path along with file name.

    WordPress : How to register a user on local machine?

    September 16th, 2010 No comments

    If you are developing wordpress blog, you might need to do testing for registered users like

    • Whether non registered users are able to view blocked posts
    • Whether restricted contents are visible to members only.
    • Which are options on dashboard accessible to various users?
    • etc

    Better you do all testing locally including user registration.
    To register a user on local copy of your wordpress, either you need to configure SMTP server locally. So mails can be send from your machine. Or you can go for a very small trick mentioned below.

    1

    Let wordpress generate whatever password it generates. You just select password that you want, say “article-stack”. Now calculate its MD5 value.



    2

    Open wordpress database. For this

    1. Type http://localhost/phpmyadmin/ in Internet browser.
    2. You can see the list of database in left side bar. You need to identify which one is used by your wordpress installation
    3. Just click on appropriate database name.
    4. You’ll see list of wordpress tables in left side bar. All tables shall be start from “wp_” prefix.
    5. Select “wp_users” table. Change the password of desired user with calculated MD5 value.

    How to send mails from your PC? 5 min setup

    Before reading this article, you are required to install Xampp on your PC. This will automatically install other needful components. Then you would have to do some changes in php.ini that i am describing below.

    Initial settings:

    Locate php.ini which should exist on following path. I am assuming that you had installed Xampp on C drive.

    
    C:\\php\php.ini
    C:\\php\php5.ini
    C:\\apache\bin\php.ini
    

    Editing php.ini:
    - Open php.ini file and uncomment the php_smtp.dll extension. This is required when sending emails to a remote server.
    - Scroll down and find the following lines:

    [mail function]
    ; For Win32 only.
    ;SMTP = localhost
    ;smtp_port = 25
    
    ; For Win32 only.
    ;sendmail_from = me@example.com
    

    - From the lines above, uncomment SMTP, smtp_port and sendmail_from
    directives, then add SMTP server, SMTP port number and your preferred email address to SMTP, smtp_port and sendmail_from directives respectively, your final code should be similar to the one below:

    [mail function]
    ; For Win32 only.
    SMTP = mail.server.com
    smtp_port = 25
    
    ; For Win32 only.
    sendmail_from = something@server.com
    

    - Replace mail.server.com and something@server.com with correct values. The default
    - Restart your server. That you can do from xampp controller.

    Please note this
    SMTP port number is “25″. But port 25 is generally blocked by your ISP. So use 5190 instead. Otherwise you may need to contact your ISP to unblock it.

    Now you just need some application that can send e-mail from your PC. You can use wordpress for the same.

    How to get the path of wordpress installation directory

    August 1st, 2010 No comments

    I seen many people asking site owners about their CMS platform.
    It is easier to know it yourself. There is a fixed path pattern of every CMS. If a site is using wordpress CMS then path pattern should be like,

    Domain Name/wp-admin
    

    If you get wordpress login page by entering above path then you surely can say that site is built on wordpress CMS. But wordpress provides an easier way to change the path of wordpress installation directory. This option is available in wordpress dashboard under settings option. If a user had changed the path then it is really difficult to guess the path. Specially when site owner restricts crawler to index their site contents. In this case below google search will not help you

    inurl:wp-admin site:article-stack.com
    

    Well! it is pretty easy to know wordpress installation directory path. Use the below path

    Domain Name/robots.txt
    

    You’ll get a text file containing path as follow

    Sitemap: Domain Name/sitemap-web.xml
    
    User-Agent: *
    Disallow: /wp/wp-admin/
    :
    Disallow: /go/
    Disallow: /forums/profile/
    

    If robots.txt revealing the path you are trying to hide then you must know why robots.txt is imported for your site.

    In case of above example, wordpress installation directory is Domain Name/wp/

    Please note this
    This hack is not to attract hackers. But to improve security only.

    Google powered youtube hacked!!

    I surprised after hearing that youtube is redirecting their users to some adult sites. Hackers placed some JavaScript and HTML code in the comments section of targeted videos. When someone starts watching targeted video, code would run automatically and redirects visitor to some adult sites.
    Google says the problem was fixed within only two hours of being reported, according to the BBC.

    “We took swift action to fix a cross-site scripting (XSS) vulnerability on youtube.com,” a spokesperson said.

    “Comments were temporarily hidden by default within an hour, and we released a complete fix for the issue in about two hours.

    “The thing with a cross-site scripting attack is that it will appear that it is a message being posted by that website, which gives it a certain legitimacy, Graham Cluley of security firm Sophos told BBC News.

    “It could be used to show a message that tells you to update your password; it could link to a malicious website; or it could attempt to phish you.”
