DNS Hijacking | How to hack Facebook accounts using it

Hi Guys, I am back after a long time and I have got something amazing for you guys. In this tutorial I am going to show you how to Hack facebook accounts by DNS hijacking!

WHAT IS DNS?

 is a network protocol whose job is to map a user friendly name like tutorials for you to its corresponding IP address like “173.245.61.120″.

What is DNS Hijacking?

DNS HIjacking also known as (DNS redirection), is a kind of malicious attack that overrides a computer’s TCP/IP settings to direct it at a fake DNS server, thereby disconfirming the default DNS settings.As we tend to all recognize, the “Domain Name System (DNS)” is there to translate a user friendly name like “google.com” to its corresponding IP Address “74.125.235.46″.

So How DNS Hijacking Works?

As mentioned before, DNS is that the one that’s responsible for mapping the user friendly domain names to their corresponding IP addresses. This DNS server is closely-held and maintained by your Internet service Provider(ISP) and lots of alternative business organizations.
By default, your laptop is organized to use the DNS server from the ISP. In some cases, your laptop could even use the DNS services of alternative organizations like Google or OpenDNS. Imagine a scenario wherever a hacker or a malware program gains unauthorized access to your laptop and changes the DNS settings, so your laptop currently uses one amongst the malicious DNS servers that’s maintained by the hacker. once this happens, the malicious DNS server could translate domain names of interesting websites (such as banks, search engines, social networking sites etc.) to IP addresses of malicious websites having a similar design to original site. As a result, you will be taken to a pretended web site rather than the one you’re intending for.


What are the Dangers of DNS Hijacking?

The dangers of DNS hijacking will vary and depend upon the intention behind the attack. several ISPs like “OpenDNS” and “Comcast” use DNS hijacking for introducing advertisements or aggregation statistics. Even though doing this may cause no serious harm to the users, it’s thought-about as a violation of RFC standards for DNS responses.

Other dangers of DNS hijacking :

Pharming: This is often a sort of attack wherever a web site’s traffic is redirected to a different website that’s a faux one. As an example, once a user tries to go to a social networking web site like Facebook.com he is also redirected to a different web site that’s stuffed with pop-ups and advertisements, this is often done by hackers so as to come up with advertising revenue.
Phishing: This is often a sort of attack wherever users is redirected to a malicious web site whose style (look and feel) matches specifically with the initial one. As an example, once a user tries to log in to his checking account, he is redirected to a malicious website that steals his login details.
So this way 1 can hack facebook accounts. He can create a program to change your DNS address and could redirect it to his rogue DNS address. That DNS will redirect the request of facebook.com to some fake Facebook site, a Facebook phisher which could steal your login credentials.

How to Prevent DNS Hijacking?

In most cases, attackers create use of malware programs like a worm to carry out DNS hijacking. These DNS hijacking trojans are usually distributed as video and audio codecs, video downloaders, YouTube downloaders or as alternative free utilities. So, so as to remain protected, it’s suggested to remain aloof from untrusted websites that supply free downloads. The DNSChanger trojan is a very good example of 1 such malware that hijacked the DNS settings of over four million computers to drive a profit of concerning fourteen million USD through deceitful advertising revenue.
Also, it’s necessary to change the default password of your router, in order to stop someone to change your router settings to exploit your DNS settings to hack you.
Installing an original antivirus program and keeping it up-to-date offers an excellent deal of protection to your pc against any such attacks.

What if you are already a victim of DNS hijacking?

If you think that your laptop is infected with a malware program like DNSChanger, do not panic. All you have got to try and do is, simply verify your current DNS settings to check if the DNS address is the same as that provided by your ISPs. Otherwise re-configure your DNS settings as per the rules of your ISP.

IP address – The Complete Guide | What is an IP address

Ip Address – The complete info
What is an IP address ?
The complete tutorial about what is an IP address, types of IP address, uses of IP address and much more. 
Read this awesome post to know more about IP address. 

Q) What is an ip address?
A) An Ip address is a label assigned to every device connected to a network or internet.Any device connected to internet could use this label to connect to another device connected to internet.
Types of ip addresses :-
1) Dynamic ip : These types of ip are always changing. Mostly broadband connections have these type of IP. These are assigned automatically by your ISP.
2) Static ip : These ip addresses don’t change. They remain same. You either had to buy one from your ISP or sometimes it comes free with your plan.
3)Public ip : Public ip address makes your device accessible to other users of internet. Anyone on internet can connect to your server using your PUBLIC IP.
To check your Public IP visit :
whatismyip.com
4)Private ip: Private ip is an ip address assigned to devices on a private network like computers present in your school/college have different Private ip address. It is used to communicate between computers on a Private network connected using hub/switch or any other way. To check your Private ip :
4.a)Open cmd .
4.b)Type ipconfig and hit enter.
4.c)The number shown against Ip Address is your Private ip.
You could assign Private ip on your own by :-
4.1)Double click on network connection icon in taskbar.
4.2)Click on Properties.
4.3)Click on internet protocol(tcp/ip).
4.4)Tick on “use this configuration”.
4.5)Enter your details.
4.6)Click on Ok.

Example scenario:
1) Let us suppose a computer Lab A in a school containing 20 computers all connected to each other using a switch and connected to a Modem[ all 20 to a single modem].
Then their *Private ip* address could be checked at cmd via point 4). This  *Private ip* is  mostly *STATIC* .
But their *Public ip* will be same as they are connected to internet via same route ie same modem. This *Public ip* will be assigned by the ISP and may or may not be *Dynamic*.

2)
 Let us take another computer lab B with same configuration as lab A. Now let us suppose computer xyz. It will definately have a different *Public Ip* as compared to Lab A, but it may or may not have same *Private ip* as that of any computer in Lab A.
There is one more thing, two devices could never have same Private ip connected to a same network. But two devices connected to different network may or may not have same Private ip.
This mean two computers either from lab A or B, both could have same *Public ip* but can never have same *Private ip*.

Example Explained :
Xyz computer From lab A:
Private ip : aaa.bbb.ccc.ddd [Generally STATIC]
Public Ip : xxx.yyy.zzz.www [Anything assigned by ISP, could be *DYNAMIC* or *STATIC* depending on your subscription]
abcd From Lab B
Private Ip : eee.fff.ggg.hhh [this could be same as Private IP of XYZ in Lab A, Generally STATIC]
Public Ip : qqq.eee.www.ttt [This could never be same as that of lab A, anything assigned by ISP, could be *DYNAMIC* or *STATIC* depending on your subscription]

In my next post i will discuss about IP addresses in even more detailed way.
Stay updated! Thank You!
