The Three-Second Theft: Why AI Voice Fraud Outruns Every Defence

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.

So, you answer your phone to the scam and… now they have your voice too.

Talking on the phone is now an unmitigated liability.

This blog is kind of an interesting hybrid:

> Every article published on SmarterArticles is authored and editorially controlled by Tim Green. Artificial intelligence tools are used within a structured and supervised workflow as research and drafting instruments. All arguments, framing decisions, source selections, and final publication choices remain human-directed and under my full responsibility.

There are references at the bottom, but I would have preferred direct links or footnotes within the article. Also, direct quotes are nice. I didn’t notice any glaring AI cliches.

AI definitely amplifies this problem, but it's not like it didn't exist before. Old people get scammed the old way all the time too. My mom calls me every once in a while asking about some freebie offer that she gets emailed from sketchy domains claiming to be spotify or something.

Not saying that "there's nothing we can do" or anything, but it does feel like this is one of those instincts that you develop growing up with the internet. Like, my first instinct reading that (and I hope getting that call) would be "what the hell is the lawyer doing at the scene". You have to treat _everything_ coming through your phone as potentially untrusted. I don't have any data on this, but it feels like my friends, and especially younger people, do that automatically.

The primary defence against all phishing is to tell yourself: nothing is ever really that urgent. Nothing is ever that good.

If they were still around i would have to warn them for sure! Crazy stuff this new future!

The problem described in the article is unsolvable, given that a mid-range desktop from a few years ago can easily clone a voice that's convincing enough and there are no guardrails to those. Some silly KYC laws might limit a highschool kid making deepfakes of his crush, but once a model exists it's trivial to spread it around, and for organized groups to get ahold of those. Similar will happen with images, it's just that nobody with any serious money bothered releasing image gen models that compete with gemini or chatgpt -- but it's just a question of time. A year or three, what difference does it really make?

As the cost goes down to near-zero you can scale it up almost infinitely, especially if the profits are high enough to get some smart people working on the problem, which going by the article is already the case ("INTERPOL's finding that AI-enhanced fraud is four and a half times more profitable than the traditional kind"; incidents rose by 26% last year). If AI does succeed on mutilating white collar work enough there will be a large supply of knowledge workers that might just join International Scam Co. rather than have their families go homeless. Drowning man clutching at straw and all.

So if technologically it's impossible to prevent and societally it's impossible to prevent (like the attorney that got pwned same as the grandma), I'm not sure if there exists an answer that isn't worse than the thing it's supposed to prevent. I suppose we'll soon be in a situation where nothing we don't directly perceive in real life is provably true. That journalism and media in general seem to be in a deep crisis of trustworthiness means that you won't even get the benefit of the chain-of-trust as a proxy for whether something is or isn't real.

Ignoring everything happening outside of your immediate surroundings is a choice, and probably even good for people's mental health, but my gut feeling is that it does make humanity as a whole dumber and disempowered. What does corruption matter if nobody cares, or even hears about it? It was AI generated by $current_enemy anyway; nothing to see here, citizen.

I've been waiting for a steelman argument why building the world's best deepfake machine is a good thing. Unironically cryptography could verify identity for all comms.

I fear this whenever I acidentally say too many words to a telemarketer/scam call.

What are legitimate uses for copying someone's voice without permission? I see none. Those scientists are just helping criminals to fully automate scamming and governments to create fake videos.

What’s terrible is each time I am forced to call the bank, the more they try to tell me voice ID is secure and want me to provide my voice to authenticate. Never. Did ya’ll never play Uplink? With voice cloning as good as it is now, there’s no way a voice ID is secure enough for authentication.

We all have a safe word in the family just for this issue to identify if it´s the real person or not.

i wish i could still warn them...

chuckadamstoday at 1:41 PM

One reasonably effective defense: "Okay, let me call you right back." Yes, there's always the whole "my phone is dead, I borrowed someone else's" or "I'm calling from a jail payphone", so I think it might become common practice to start making authentication phrases or "tell me something only we know".

Another pillar of basic trust that's being eroded on an industrial scale. Sigh.

> ... the hardest for its victims to be believed about — because the evidence, by design, sounds exactly like someone they love.

Uh? Surely this makes believing the victims easy not hard to believe.

Its like revenge porn. "It's not me. It's a deepfake" is easy to believe.

They make you give a voice sample now when you're arrested. You need to do so in order to use the phone.
