Security

Too easy to crash

http://securityaffairs.co/wordpress/39363/hacking/hacking-parrot-drones.html

telnet 192.168.42.1
ps | grep dragon
kill -9 ###

Actually there is even quicker:

telnet 192.168.42.1
kk

WEP?

Apparently possible to setup WEP, or even WPA?

bcmwl addwep 0 1234567890
bcmwl wsec 1

Permanent (! reset wouldn't clean it, maybe flashing from USB?)

vi /sbin/broadcom_setup.sh
At the end of the create_access_point
Before the print out of success
add the two lines:
-------------
bcmwl addwep 0 1234567890
bcmwl wsec 1

Problem is that it may impact link quality and anyway it's incompatible with a SkyController...

telnet password

That's the minimum we can do:

telnet 192.168.42.1
# choose a new password
passwd
# fix bug in /etc/passwd (trailing spaces after /bin/sh)
sed -i 's/ *$//' /etc/passwd
# redirect root home to /home (where there is already a .bashrc)
sed -i 's#/home/root#/home#' /etc/passwd 
# redirect telnet login to /bin/login
sed -i 's/sh -l/login/' /bin/login.sh
# reboot
/bin/ardrone3_shutdown.sh
