Can WhatsApp, Signal or Telegram be hacked through a SIM SWAP attack?
In Cuba the telecoms/ISP monopoly, Etecsa, works with the political police to spy on dissidents, journalists and others.
A common attack in Cuba is therefore SIM Swapping which is easy for them. It is also effective in order to eavesdrop on phone conversations and SMS.
Would the SIM Swap enable the attacker to also hack WhatsApp, Signal or Telegram and gain access to these messages or calls? If so, are there any measures that can be taken to prevent the attacker from accessing the secure messaging apps via a SIM Swap attack?
