one the most popular broadband services in India with high speed
facilities of upto 2 mpbs. But a large number of users of this service
are vulnerable to hacker attacks because discovering and hacking the
vulnerable victims of this network is shockingly simple. If you are a
Bsnl Broadband user then immediately assess the security of your
internet connection and take appropriate steps to secure yourself.
First
lets see how simple it is to hack bsnl dataone broadband usernames and
passwords. For this you shall need a ipscanner tool called Angry IP
Scanner http://www.angryziber.com/ipscan/ or anything similar.
Ok so lets begin... Get your IP from :
www.ipmango.com
Step 1 : Start Angry IP scanner and goto options > ports. Type in 80 in the first ports textbox and click ok.
Then goto options > options ; in the display section select "only open ports" and click ok&save.
Now
on the main screen put in the ip scan range as something 59.*.0.0 -
59.*.255.255 (for e.g. 59.95.2.3) and click the start button. And the
list that shall follow next are the victims. In this example we choose
the range 59.95.0.0 - 59.95.255.255. You will be surprised at the
number of victims you discover.
Step 2 : Pick the ip-address of
any of them and open up your browser and type in http://59.*.*.* (the *
should be replaced by the values from the ip you are using. A box will
popup asking for username and password. Enter the username : admin and
password : admin .There is a high chance that you will be able to login
with that username and password.
admin-admin is the default username and password that is set while manufacturing the adsl modem devices.
What follows next is the modem administration panel.
Simply
search for the "WAN" option and click it. On the next page you will
find the username and password of that user. now right-click on the
page and click view source. in Mozilla/Opera This frame -> view
frame source
Now in the source code search for this : INPUT TYPE="PASSWORD"
and the value field of this input element will have the password
if its not there as in case of D-Link DSL 502T ADSL Routers the search for this
input type="hidden" name="connection0:pppoe:settings/password" value="password" id="uiPostPppoePassword"
and the value field will have the password
Well
each steps take less than 1 minute so getting username passwords wont
take even 2 minutes and is easier than sending a mail.
And this exposes the weak security of bsnl broadband users.
Well
this is not a weakness but more of a mis-configuration which leads to
insecurity. If you understand networking then you would probably
realise that it was merely logging into the remote administration
service of the modem and nothing else. This was not really hacking but
a simple search of victims who are absolutely ignorant of their weak
security on the internet.
Most routers have an option where
remote management can be disabled. In other words, you can only connect
to the configuration interface from the internal network, not the
WAN(Internet) side. You would definitely want to make sure remote
management is not active to protect yourself.
Note : On SmartAX
MT880 eventhough Remote Management is disabled , it permits remote
logins from over the Internet. So change your mode administration
passwords immediately.
The problem is that the professionals at
Bsnl are ignorant of such simplicity of networking and unable to advise
the users or guide them to take proper security measures leaving their
customers and themselves absolutely unsecure.
Now lets check a
few more options related to this issue. A bsnl broadband modem can be
used in two modes. RFC Bridged mode and pppoe mode.
In the RFC
Bridged mode the device behaves like a modem device that is attached to
your computer and you use some dialup software to dial into the isp
through this modem.This is PPPOE from the PC and the adsl device is a
good modem. This mode is safer as the username password are on your pc
and nothing is on the modem.
In the PPPOE mode the adsl device
becomes a router - a distinct network device with many features
enabled. In this mode the username password is stored in the modem
which will dial to the isp and establish the internet connectivity. The
computers will just connect to this router who would be their primary
gateway. Now this is the mode where the risk exists.
If remote
administration is enabled the remote users from the internet can login
to this modems administration panel. Now the main problem is the
default admin username-password which most users dont change due to
ignorance. "admin-admin" is pair that works in most cases giving you
full access to the modems internals. What follows next is simple as
drinking a glass of orange juice.
Many users install firewalls
and think they are safe, but they fail to understand that the firewall
protects their PC not the "router" since the topology is like
(PC) -> router -> internet
So how should you secure yourself ?
1. Use RFC Bridged mode if it is sufficient for you.
2. Change the default admin password of your modem.
3. Disable wan ping reply . ( this will prevent the hackers from directly discovering your pc when it is on the internet)
4. Disable remote configuration feature.
5.
Check your broadband usage on a regular basis and compare it with your
own surfing schedules to check whether someone else has used it or not.
If suspiscious usage is indicated then immediately change your bband
password as well. Or a better suggestion would be to change broadband
passwords on a regular basis.
Try to spread the security
awareness to your friends and other relatives who are using Bsnl
broadband and encourage them to secure their internet connectivity.

Great article! Cheers big
Great article!
Cheers big ears
This is the techniques of old
This is the techniques of old hackers and geeks. Now a days all the connections of bsnl in major cities and towns are port binded that means only u can use internet using your credentials with that specific phone number only and not from any other even if u got their credentials. please rewrite this article for a new method and a professional way.
