Hackers abused API to verify millions of Authy MFA phone numbers
www.bleepingcomputer.com
Twilio has confirmed that an unsecured API endpoint allowed threat actors to verify the phone numbers of millions of Authy multi-factor authentication users, potentially making them vulnerable to SMS phishing and SIM swapping attacks.

        I’d prefer fuck-you-fines making it impossible to ignore the security that are actually enforced.

          And that’s why its important to prefer internet services hosted in particular companies. The English legacy of law has been very poor at keeping society safe from corporations because these laws were established when the British Empire was a vast trade corporation with an inbred person as CEO by way of the pope said Jesus wanted that family to be in charge.

          What’s crazy making is a lot of the places the British destabilized the indigenous people had very advanced methods of ensuring society benefited everyone. Not all of them of course, but enough of them that its hard to see the English legacy of law practice as anything other than fundamentally broken and not worth the amount of spread it was forced to have at gunpoint. Like when I hear about how Iroquois nation justice worked I can’t help but feel something truly special was lost by way of colonists wanted to profit off beaver pelts

      Especially with such careless failures. If some employee was tricked through a well-planned social engineering attack, or they used some mega obscure day0 vulnerability, I’d not be happy, but shit happens, I guess. But not sending my phone number when someone just posts some GET command to an API should be a no-brainer…

    What confuses me is even a half-competent audit and pentest would absolutely have found an api endpoint that’s going to absolutely leak customer data, so the assumption I have to make is that, yet again, a “security” company can’t be fucked to do the bare minimum to ensure their security shit is you know, secure.

    That’s especially bad, because the default behavior, iirc, is to have Multi-Device turned on, which means anyone can potentially add their device to your account and access your TOTP.

    And I don’t expect most users to know how or to remember to turn it off.

    Let this be a reminder not to use Authy or Google Auth or Microsoft Auth if you can help it. Your best bet if you can help it is a Yubikey or Nitrokey. If you can’t far better to go with Aegis or Ente Auth. If you need easy sync across devices, Aegis has that, but most of the security experts I know recommend going with 1Password as your MFA solution with sync. I personally don’t trust 1Password as a for profit corporation, but I also accept I don’t get paid to know about computer security to the degree that an actual security expert is

    Thank fuck I got away from Authy years ago - cost me my Twitch account (because apparently Twitch straight won’t allow you to switch away from Authy), but it was worth it to secure the rest of my things

    Lol it’s taken me a while to come around to MFA (I used to hate it but I’ve started using open source MFA apps), but my hesitation to use proprietary solutions has proved smart.

    Oh man this is going to suck.

    We were looking for an authentication setup to allow for SSO and one of the front runners was Twilio. They have a meeting with us next week and I am not looking forward to this second hand embarrassment.

    So for common folk like myself, what do I need to do? I used Authy for a few sites. Can a bad actor pretending to be me now get access to those sites?
