Hidden SSID

Postby heiowge » Tue Jun 07, 2011 12:30 pm

A recent (not yours, sorry) article suggests hiding your router SSID since the default name can give bandwidth thieves easy access.

I have just changed mine from the default (which I'm not saying, or what would be the point!) to Surveillance Vehicle T7. I thought it would worry my neighbours! :twisted:

Anyone got a better SSID I could use? :lol:

:D

I like it!

But did the article not mean hide the SSID completely - i.e. not broadcast it?

For a time I tried setting my router to NOT broadcast the SSID, but I found that my son's (Vista!) laptop could not connect unless the SSID was broadcast. Sigh...

Hiding the SSID does not significantly increase security. Broadcasting a default SSID demonstrates that you can't be bothered to change the settings, making it a prime target for attack, but it is still possible to connect to an AP that does not broadcast its SSID. you just need to find the SSID in other ways, like sniffing the connections of the devices connecting to it.

finding a wireless point without a ssid is quite easy really. There is a program (can't remember what it is called) that sniffs for wireless networks and just picks up everything, and if you have hidden the ssid it just has a blank cell in the table. Can still find you ap mac address, sometimes ip and strength, etc


Changing from the default ssid however means that it is harder to guess what hardware you are using, meaning that trying to use the default key for your hardware is harder.
For certain you have to be lost to find the places that can't be found. Elseways, everyone would know where it was

I think that's the point they were making. :lol:

Plus it's more fun with a scary SSID. :twisted:

however if you were really cleaver you could use the 'MAC OUI' and find out the manufacture of the box/network card, and from there do some guessing.

Or just look though the window :D

They'd have to look through a window, round a corner and under a desk! :lol:

Never ceases to amaze me the number of people who set their SSID as their family name......

I feel sorry for the people with the BT homehub which has been set up as an open access point for BTFon and there's no support for 128-bit WEP, so you'll be even less secure using 64-bit WEP. There's also no MAC address filtering for limiting access to only pre-defined devices.

But, if they are using WPA2-PSK with a random key up to 63 characters long the cracking is going to take a long time. There are roughly 73 keyboard characters that can be used, so some rough maths with 1000 attempts per second would take about 7.12940856 × 10^120 years to go through every possibility! I'm not sure the wireless access point will be around that long :wink:

I know that everyone will soon have to look at replacing or upgrading their network hardware because of IPv6 upgrades on the Internet.

Most people don't use random passwords. The chances are that if they use their family name as the SSID, the password is based on names or birthdays of children or pets. That gives you a far smaller pool of potential candidates, especially if you know the family.

If you know them surely you could just ask them...

Have you all seen http://passwordcard.org/ I think it is a simple, good idea for non-secure sites or better still, for Linux users, install pwgen

sudo apt-get install pwgen
