  • Signal and ProtonMail appear on list of sites used for govt surveillance tool

Would subpoenas count as 'working with the government'?

I expect Signal to answer subpoenas, after all.

    03046512336612478855 Sounds like the scrapeable data is plausibly just:
    Signal - phone # used on signup

    If you have my phone number, and I have not marked it as hidden from search in my Signal account settings, then the phone number can be looked up by anyone from within the Signal app – The presence of a Signal account associated with a phone number can be established that way. But Signal doesn't otherwise publicly publish a list of phone numbers.

        raccoondad they're in no position to issue subpoena or in any way be part of such process so no, it does not relate.

          Signal complies with government requests , however , they likely can't provide much metadata.

          Interestingly though, the FBI recently suggested to U.S. citizens to use signal app do to Chinese hacking of SMS network.

            locked Every company does, those who claim they don't simply bullshit to the public to not lose their PR and/or reputation. There were only a small subset of events where company (as in a single person responsible for the service) would rather cease to exist than to comply.

                03046512336612478855 However it was surprising for me to see Signal and Proton on the list.
                Does anyone know - what kind of data from Signal or Proton is harvestable like this?

                Hopefully its just a single field like:
                "has phone # registered on Signal - yes/no"
                or
                "list of proton addresses registered on other services"

                ProtonMail does have a public HKPS keyserver that distributes public PGP keys associated with accounts. It generates dummy entries to dissuade casual scraping, but importing a dummy key into gpg fails. So it does not surprise me seeing another entity attempt to enumerate it for 'research'.

                  geko Yes, and truecrypt, as I said a handful of people responsible for various services decided to cease to exist rather than comply.

                    fid02 which is why you should only use the number to sign up in Signal, and thereafter use a nickname, hiding your number from those outside of your circle

                        locked Signal complies with government requests , however , they likely can't provide much metadata.

                        Yes. They have released documentation before of what their response to a subpoena looks like.

                          can you then sign on to Signal from another device using the nickname? I don't think a "secure" messaging service that requires a phone number is really any better than imessages for example
