Recently started turning my phone on airplane mode and it got me curious. Airplane mode is supposed to turn off all radio signals. So, I won’t be able to receive or send messages (emails aswell, and so on). Once airplane mode is turned off, I can send messages again and I receive all messages I would have gotten otherwise.
The way several messaging apps work is the message I send is encrypted when sent to the server, then decrypted, and then sent to the intended client in a decrypted state. MITM attack should be able to happen when the message is sent unencrypted to the intended client. But if I am in airplane mode (I do not receive the message), can the message still be intercepted with such an attack?
Thinking that if I was using public wifi in a store or something, then I could have my device on airplane mode so no messages are received on my end. Till I get home on my own network and turn airplane mode off. Receiving those messages when it is now a secure location.
