New sim swap hacks highlight carriers’ wobbly securityMartha DegrasseLight Reading

Diagram demonstrating how the attack works

Researchers at Princeton University called three of the four major [US] carriers and tried to convince customer service representatives to move phone numbers to new sim cards. Verizon, AT&T and T-Mobile each received ten calls from the researchers, who posed as customers.

Astoundingly, in all 30 cases the fake customers successfully convinced the carriers to move the numbers to new sim cards.

This matters because so many other services (such as banking systems) rely on SMS for authentication. If you only need to convince one customer service representative to swap a phone number, you could potentially have access to… almost anything.

Google Duplex is not creepy

Google Duplex is not creepy

Further to my point yesterday about why I don’t agree that Google’s new AI-powered phone calling technology is creepy.

…we live in a world where most restaurants and shops can only really be dealt with by phone – which is very convenient and nice, but (to varying degrees) it doesn’t work for deaf people, introverts, anyone with a speech impediment or social anxiety, or people from Glasgow. Those people have every right to a nice dinner and this makes it possible – or at least much easier.

Why are companies installing badly designed phoneboxes?

diamond geezer on why companies are installing badly designed phoneboxes

I can’t say I’ve noticed new phoneboxes popping up, but maybe things are different in Edinburgh. Nevertheless, I found this blog post by diamond geezer fascinating.

BT’s new InLink sounds especially awful:

All the action takes place on the thin side farthest from the road, where no separate receiver is apparent. Instead there’s a socket for a headphone jack, provided by the user to cut costs, and a loudspeaker at waist height which’ll broadcast across the pavement…

Most striking is the big red button which if pressed immediately dials 999, an innovation surely far too tempting for passing fingers, which must have emergency switchboards cursing.

So why in this day and age would new phoneboxes be emerging? The answer is depressingly familiar.
