Hacking the 2.0 Hub.

10 posts in this topic

So I have some great news about the Iris Hub 2.0. I found out how to get serial output from the hub.

What you need Arduino Uno and some jumpers

1.Jump reset to ground on the Uno
2.Ground pin 1 on the J1 (pin 1 is the box contact)
3.J1 Pin 4 to Uno Pin 0
4.J1 Pin 5 to Uno Pin 1
5.Plug in the Arduino to your computer and I use Putty on speed 115200
6.Plug in the hub and you will get this.

Looks like Poky/Yocto uses an empty password by default... but I'm sure you tried that already (of course, username being "root").
Unless you can guess it or somehow brute force it, linux accounts seem to be pretty hard to hack.

Leaving the password blank would be pretty boneheaded since it is always connected to the internet.... I wonder what you would see if you sniffed the traffic though during a software update?
