What can someone do with a MAC address?

Could someone who knows the WLAN MAC address of a mobile phone do anything malicious to the device at all? Or any other type of computer/device for that matter?

Nothing really. MAC address only identifies a network communications device. Some ISPs only allow certain MAC addresses to access their service, and routers can be configured to only allow certain MAC address to connect through it. If you know the MAC address of someone’s device it is possible to ‘spoof’ it and steal someone’s internet connection. The only way you can connect to a computer remotely is using an IP or Internet Protocol address, and even then there are many security features in place to prevent you from doing such.

Could someone who knows the WLAN MAC address of a mobile phone do anything malicious to the device at all? Or any other type of computer/device for that matter?

It is effectively like having the registration of your car. It uniquely identifies hardware on a network, you can change it but there really is no need.

In other words if you joined a wifi network then someone looking for your phone with access to that network could then identify your phone. Worst case scenario is that someone could change their mac address to yours and cleverly intercept your traffic by spoofing.

A criminal could also commit a crime with hardware pretending to be your phone. There are no real implications of this however as I don’t think MAC addresses hold up in court as identification evidence.
