Is 4g actually less secure?
I thought it was fine… Down grade attack is done via 2g/3g which have no security
They downgrade to 2G, whose encryption is cracked trivially with modern hardware and there’s no tower authentication so it’s possible to have the phones connect through the css.
Disable 2G (or use GrapheneOS) and you’ll mitigate this specific attack.
3G and 4G have some flaws themselves(from Blackhat ‘17: https://youtu.be/BFkrK5kaH4o)
Damn… So 5g only should be used?
I was operating under idea that 4g was better than 5g for privacy and security. I guess I need to hit the books again
Never heard being
Well…

It’s safer to just assume that your cellular traffic can be monitored and SMS can be spoofed. So, use VPNs for data(and DNS) and Signal/whatever end to end encrypted messaging software.
Ohh i am balls deep into privacy game.
Just trying to sort out if 5g is better over 4g here for daily activities.
5g uses more battery so I generally stay on 4g but if 4g is less secure, might need to go with 5g
Also, doesnt 5g provide telco with with you position too?
IE they can tell you are on 5th floor v 15th
Yeah, 5G uses beamforming so they know where you are with pretty high accuracy.
Nothing will prevent them knowing your location, if you’re transmitting a signal it can be located with WWI level technology. But the providers do log that data so it can be available for law enforcement.
