So, this is nice and dandy. I can control an LED, as can any user. But how can I hack Matter devices?

Well, I don’t know. But! It is open-source. Feel free to check out the project and build IoT devices at home.

GitHub

And feel free to find security vulnerabilities in the code. Visit the following URL for more details. CSA - report vulnerability

To get started with hacking, you should understand how Matter works. The following are some useful commands/tools to help you get started.

Linux#

sudo apt install avahi-tools; avahi-browse -a | grep matter

tcpdump -i yourinterface dns.resp.type == 33 and udp.port == 5353 and dns.resp.name == “_matterc._udp.local”

macOS#

dns-sd -B _matterc._udp local

dns-sd -L ID_from_previous_command _matterc._udp local

or install Discovery - DNS-SD browser

iOS#

Discovery - DNS-SD browser

Thank you, happy hacking, and don’t forget:

HACK THE PLANET!

PS: Please do not launch attacks on the network that could disrupt others’ experiences. This includes excessive traffic generation, ARP poisoning, etc.
