    Since when was sms ever secure? My understanding is that messages are sent in the clear, meaning your carrier and the recipient’s carrier both have the opportunity to intercept messages.

    I mean that’s the message content, not the authentication, but still, sms is the opposite of secure, always has been.

      Not true. SMS is encrypted in 3G, LTE, 5G. Block cyphers like Kasumi and A/9 are used. SMS is reasonably secure, because it’s hard to infiltrate telecom systems like S7

        cough You can pay a few grand and get access to SS7 networks.

        Might be out of reach for most of us, but we can rest assured that any and all security firms and goverrnment agencies have access to this information at a moment’s notice.

          Simply paying is not sufficient. You need to be a telecom company, or a researcher afaik.

          In what world would the US gov care to get into your bank account? Or your Facebook account when it’s already tightly controlled?
