Each SMS message carries the sender, recipient and full text. > Harvesting every single SMS message is trivial and so undoubtedly the NSA does it, they can run simple keyword matching an statistical analysis, and keep everything in case it's interesting.
Signal users can choose to "lock" their account with a PIN so that an apparently new phone with that number doesn't get access unless its owner presents the PIN.īut it's only OWS that control that check, right? > "Phone number based apps are vulnerable to SIM hijacking". PGP offers only a signature mechanism, so a recipient can prove you sent a message, whereas in Signal the recipient only has their own certainty that it's not a forgery - nobody else could have forged it, but they easily could and so they can't use that as proof of anything. In contrast old Signal encrypted messages are probably completely useless because the keys needed to decrypt them likely no longer exist anywhere. For example there's no Forward Secrecy, so it makes sense to steal encrypted PGP data on the expectation that you'll some day be able to decrypt it. GPG's security is definitely not "superior" because it's based on the PGP hybrid crypto which is from last century. So instantly such government bulk collection isn't possible. (Messages to friends or to those happy to receive messages from strangers don't need to reveal who sent them to Signal's own systems, only to the recipient). In contrast harvesting even the encrypted Signal messages is difficult, and even with a successful (and relatively unlikely) breach of Open Whisper Systems itself neither the contents or in most cases senders are revealed by doing this. Harvesting every single SMS message is trivial and so undoubtedly the NSA does it, they can run simple keyword matching an statistical analysis, and keep everything in case it's interesting. Signal users can choose to "lock" their account with a PIN so that an apparently new phone with that number doesn't get access unless its owner presents the PIN.Īssuming that you think the phrase "non-repressive state" includes countries like the US that spend billions of dollars to spy on their own citizens, just the first item is already a huge benefit.
"Phone number based apps are vulnerable to SIM hijacking". If Open Whisper Systems says you're getting Signal, Google don't get to substitute something else except if you buy a Google phone and only then by replacing your OS.

"Most people install it through the Play Store": Play Store APKs are signed by their creator, not (only) by Google. Pervasive Monitoring Is An Attack and so protection against this is far more than "just Marketing". Also like modern TLS the behaviour is that you are always protected by the protocol from passive eavesdroppers regardless. " can change repeatedly": It will tell you this happened, allowing you to take whatever action you think is appropriate.
