      But their system is designed for people to call each other so that they can order fast food. Not to secure a $25m irreversible transaction

      Well the environment around them is radically changing and if they can't adopt people will flock to services where this kind of stuff can not occur.

      It’s not about securing anything. It’s just basic service levels and good opsec. It’s like someone can shut off your internet by calling your ISP. Could be as annoying as you can’t watch cat vids on YouTube or bad as botched your trade with 100x leverage.

      Right, and if my ISP permitted that behavior I'd likely switch. Same goes for my phone. If my phone is ever ported in some sort of attempt to log into any account of mine (not just a $23 million account), I'm ditching that carrier.

      Agree. But they are all that bad. So I also agree with Peter’s view that something should happen to shock the system to improve. Things need to improve on all levels: stop easy if porting, stop recommending SMS as 2FA, etc.

      SMS as 2fa is better than no 2fa, but lulls people into a false sense of security. And most people won't install a TOTP app. But if you're dealing with that much money, you're epically moronic to not spend even a day reading about security. Prob bragged about his holdings too.

      It’s really surprising how people are calling for the phone company to take a DNA test before porting your number, but no one asks if maybe the exchange should, I dunno, do a Skype call before releasing $25m

      I wouldn’t be that surprised if it turned out they did take some extra safety measures, and the attacker managed to beat those too. It would make sense not to mention this, to increase chances getting a favorable result in the case

      Middle ground: Give users the option to reject all porting attempts.

      Every additional option increases the size of the sign-up form, increasing customer worry and loss of potential customers https://unenumerated.blogspot.com/2015/10/minimizing-consumer-worry.html … They might though offer this as a premium service and charge much more for it (for the increased liability).

          Right, but it could just be an opt-in feature they provide on request, and not prompt you to decide when you sign up. Let me be clear here, I'm not seeking mandates, only speculating the consequences of ignoring it should porting scams continue to increase.

          They can't even get a handle on the spam calls. I thought it was just me until everyone started claiming they get them multiple times a day. AT&T only provides an app called "Call Protect", where it flags the numbers when they call so you know to ignore them, but it still rings.

          My point here I guess is, I think there's an underestimation going on regarding the generals public willingness to move to better services, even if those services come with a few extra fees.
