Hi Mates, Happy New Year To All !
So let see the DNS Hijacking Vulnerablity making Thousends of Websites hosted on 000webhost and other free hosting webhosting Proivders.

Step 1 : signup for a account on 000webhost.com
it will give you a address like abcd.something.com
for example mine was : http://testingfu.comule.com

Now Goto cPanel
and Look for IP Adress, you'll get something like "31.170.163.140"

Now Goto Bing .com and type dork ip:31.170.163.140
if you want .gov .edu or any other particular domain then dork will " ip:31.170.163.140 .gov "
or " ip:31.170.163.140 .edu "
all server ips
Server 1 with 253 ips
31.170.161.1 - 31.170.161.253

Server 2 with with 253 ips
31.170.162.1 - 31.170.162.253

Server 3 with 242 ips
31.170.163.1 - 31.170.163.241

Now come to Search Results 
 i got The Target csirt.gov.bd
i just open this url :
abcd.csirt.gov.bd
and here a error page of 000webhost.


which shows that the dns is configured so that the site is forwarded to Nameserver of 000webhost
now what i did is enter in my cpanel which i created at 000webhost and park a subdomain :

men.csirt.gov.bd
bd.csirt.gov.bd
and done added a deface page to my public_html
and the website defaced .
