Things are heating up. Millions of people are taking to the streets against Trump's rising authoritarianism. Communities around the US are organizing to defend against ICE raids, to protest Israeli genocide, for mutual aid, and for other forms of fighting fascism. Signal can help people safely organize in all of
That’s the dilemma with modern commucations. If you use signal or similar apps, your device can get hacked with pegasus or similar malware. AFIAK, walkie talkies and ham radios don’t really have “backdoors” (unless they messed with the supply chain), you hold the button and it transmits, let go and it doesn’t transmit. Dead simple. If you do encryption using a separate non-internet-connected device, then transmit it over the old-school radio, its virtually unhackable.
So you really have to weigh the risks.
Are you trying to have Perfect Forward Secrecy and is Pegasus not a risk to you?
Or do you prefer to be secured against pegasus, but use a clunky non PFS encryption?
Are you doing all your communications before the protest? (in which case you can use a phone with signal)
Or do you also want to have comms during the protest? (in which case, radios have no IMEI and cannot really be “hacked” and encryption is done on a separate device)
