Sounds like AI is just greasing the wheels of a long established 'grandparent scam'... goes something like this:
1) voice one: young adult calls, sobbing 2) grandparent inquires with a name... "Ben, is that you?" 3) voice one: "Yes grandma, it's me, Ben... I'm in trouble, please don't tell mom 4) voice two: "Hello, I'm attorney..."
My grandmother fell victim to this almost 20 years ago, which only stopped when Western Union refused to let her continue sending wires... she was forced to call her daughter (at which point they just called my brother.)
Our takeaway (at the time)... the voice doesn't even need to be terribly accurate, since the original interaction is brief / somewhat inaudible over the tears. Typically just requires an older vulnerable adult, a lucky strike with the initial setup (e.g. grandparent actually has a grandkid), and a lot of high pressure / duress salesmanship.
I remember my JROTC instructor also running into that and how she said afterwards they have a secret phrase between them two as a way of verifying it's truly them.
lucky strike is the key here they can do this with VOIP really easily to massive amounts of numbers. its staggering amounts if you look at the traffic really. worst is if they proxy that via residential proxy services which often come from end-user / individuals phones so the traffic is hard to detect for carriers etc. since it looks like a regular VOIP app connection.
I told my parents that I will never ask for money, doesn't matter the situation, even with live video, it's trivial to generate live audio and video nowadays.
I hope they got the message.
