The latest theft of my voice introduced me to a brand new fork within the street when it comes to how AI already has the potential of inflicting social disruption. I used to be so bowled over by the standard of the cloned voice (and in that extraordinarily intelligent, but comedic, type by one in every of my colleagues) that I made a decision to make use of the identical software program for “nefarious” functions and see how far I might go with a view to steal from a small enterprise – with permission, in fact! Spoiler alert: it was surprisingly simple to hold out and took hardly any time in any respect.

Certainly, for the reason that idea of AI grew to become extra mainstream in fictional movies resembling Blade Runner and The Terminator, folks have questioned the relentless prospects of what the know-how might go on to supply. Nonetheless, solely now with highly effective databases, rising laptop energy, and media consideration have we seen AI hit a world viewers in methods which are each terrifying and thrilling in equal measure. With know-how resembling AI prowling amongst us, we’re extraordinarily prone to see artistic and somewhat refined assaults happen with damaging outcomes.
Voice cloning escapade
My earlier roles within the police pressure instilled in me the mindset to aim to assume like a felony. This strategy has some very tangible and but underappreciated advantages: the extra one thinks and even acts like a felony (with out really changing into one), the higher protected one might be. That is completely important in retaining updated with the most recent threats in addition to foreseeing the developments to come back.
So, to check a few of AI’s present skills, I’ve as soon as once more needed to tackle the mindset of a digital felony and ethically assault a enterprise!
I lately requested a contact of mine – let’s name him Harry – if I might clone his voice and use it to assault his firm. Harry agreed and allowed me to start out the experiment by making a clone of his voice utilizing available software program. Fortunately for me, getting maintain of Harry’s voice was comparatively easy – he typically data brief movies selling his enterprise on his YouTube channel, so I used to be capable of sew collectively a couple of of those movies with a view to make audio take a look at mattress. Inside a couple of minutes, I had generated a clone of Harry’s voice, which sounded similar to him to me, and I used to be then capable of write something and have it performed again in his voice.
To up the ante, I additionally determined so as to add authenticity to the assault by stealing Harry’s WhatsApp account with the assistance of a SIM swap assault – once more, with permission. I then despatched a voice message from his WhatsApp account to the monetary director of his firm – let’s name her Sally – requesting a £250 fee to a “new contractor”. On the time of the assault, I knew he was on a close-by island having a enterprise lunch, which gave me the right story and alternative to strike.
The voice message included the place he was and that he wanted the “ground plan man” paid, and mentioned that he would ship the financial institution particulars individually straight after. This added the verification from the sound of his voice on prime of the voice message being added to Sally’s WhatsApp thread, which was sufficient to persuade her that the request was real. Inside 16 minutes of the preliminary message I had £250 despatched to my private account.
I need to admit I used to be shocked at how easy it was and the way rapidly I used to be capable of dupe Sally into being assured that Harry’s cloned voice was actual.
This degree of manipulation labored due to a compelling variety of related elements:
- the CEO’s telephone quantity verified him,
- the story I fabricated matched the day’s occasions, and
- the voice message, in fact, sounded just like the boss.
In my debrief with the corporate, and on reflection, Sally acknowledged she felt this was “greater than sufficient” verification wanted to hold out the request. Evidently, the corporate has since added extra safeguards to maintain their funds protected. And, in fact, I refunded the £250!
WhatsApp Enterprise impersonation

For instance, I’ve lately been focused with an assault that, on the face of it, seemed plausible. Somebody had despatched me a WhatsApp message purporting to be from a pal of mine who’s an government at an IT firm.
The attention-grabbing dynamic right here was that though I’m used to verifying data, this message arrived with the linked contact title as a substitute of it displaying up as a quantity. This was of particular curiosity, as a result of I didn’t have the quantity it got here from saved in my contacts checklist and I assumed it could nonetheless present as a cellular quantity, somewhat than the title.
Apparently the way in which they finagled this was just by making a WhatsApp Enterprise account, which allows including any title, photograph and e-mail deal with you wish to an account and make it instantly look real. Add this to AI voice cloning and voila, we now have entered the following technology of social engineering.
Luckily, I knew this was a rip-off from the outset, however many individuals might fall for this easy trick that would finally result in the discharge of cash within the type of monetary transactions, pay as you go playing cards, or different playing cards resembling Apple Card, all of that are favorites amongst cyberthieves.
With machine studying and synthetic intelligence progressing by leaps and bounds and changing into more and more out there to the lots lately, we’re shifting into an age the place know-how is beginning to assist criminals extra effectively than ever earlier than, together with by enhancing all the prevailing instruments that assist obfuscate the criminals’ identities and whereabouts.

- Maintain up to date on the most recent developments in know-how and replace the coaching and defensive measures accordingly
