Google To Replace SMS Codes With Mobile Prompts in 2-Step-Verification Procedure (bleepingcomputer.com) 181

Posted by msmash from the interesting-moves dept.
Starting next week Google will overhaul its two-step verification (2SV) procedure and replace one-time codes sent via SMS with prompts shown on the user's smartphone. From a report: This change in the Google 2SV scheme comes after an increase in SS7 telephony protocol attacks that have allowed hackers to take over people's mobile phone numbers to receive one-time codes via SMS and break into user accounts. The rollout process for this feature is scheduled to start next week when Google will invite users to try mobile prompts instead of receiving a one-time code via SMS. Users need an Internet-connected smartphone to use this feature. Every time users will try to log in, Google will show a prompt on their phone asking the account owner to approve the login request. There's no one-time code that users have to fill in, and users can authorize a login request with the tap of a button.

        Normally they do post to try to hit a quota. As I just posted elsewhere in this thread, posts on weekdays are almost always 40 minutes apart and it's very periodic and regular. Often times, the stories show up at the same time each day. And when they deviate, the posts still show up at times that are divisible by five, such as 1:45 or 3:10. The weekends are a little more irregular, but it's probably because EditorDavid is posting instead of BeauHD and msmash. Even on weekends, they're usually spaced just ab

        That exact use case - as an emergency phone in the car or summer cottage etc. - is why people still have "dumbphones" that can't run apps.
        Batteries in those can last for six months or more, where as a "modern" smartphone won't even last for a couple days when turned "off".

        • A modern smart phone has no problem lasting up to 2 weeks while ON and on low power mode. As for being off, my old S6 which has been lying in my draw unused for a year still has 70% charge.

      Google has been doing phone app prompts for 2FA for a while.

      If you're talking about the Google Authenticator app, then yes, this is different. I started using it on my Galaxy S7 this week.

      The way it works is, you hit your username and login, and instead of a screen that asks you to type in the code you received, it basically just says "Wake up your phone." When you do, you immediately see a screen saying, "Is this you trying to login? Yes/No." You hit the Yes button and the site instantly logs you in. It's pretty slick, actually.

        Nonsense.

        Those emails are important. Not when it actually was your device that was prevented from logging in, but when it wasn't. In that case, the email informs you that someone is trying to get into your account, and that they have your password. Which means you should change your password, right the hell now. Unless of course, you recognize the login attempt because you were the one that made it.

        If you want to stop getting those emails, turn on 2FA.

        • Nonsense. Those emails are important.

          Given that the only person who is hindered from reading it is me, I don't think so. The chances of me seeing it depend on me accessing my gmail in the very short bit of time between the one failed login attempt and the second successful one when the hacker deletes it.

          He's actively accessing my account. I'm not. Who is going to get to that email first, do you think?

      If you're using 2FA and want to use POP/IMAP or other protocols that don't know how to deal with 2FA, you have to set up an application-specific password. This is a high-entropy password that Google generates for you, and which should only be used on one machine and one application. You have it generated, copy/paste it into Thunderbird, tell Thunderbird to save the password, then you never see it again. The Google POP/IMAP servers do some additional checking to try to verify that the password only comes fro

        "special app" or no, ss7 IS used to locate the handset, allow it to connect to a cell site and determine if traffic is allowed to flow to and from it. Again, if SS7 is hijacked, how are those processes NOT compromised?
