Timeline: How It Unfolded

March 2019

A UK energy company CEO receives a phone call from what sounds exactly like his boss — the head of the German parent company.

Same call

The "boss" urgently requests a wire transfer of €220,000 to a Hungarian supplier, saying it must be done within the hour.

Within minutes

The CEO, recognising the voice and accent perfectly, authorises the transfer to the bank account provided.

Hours later

The money is moved from Hungary to Mexico and then distributed to other accounts, making recovery impossible.

Next day

The real boss denies ever making the call. The company realises they've been scammed using AI voice-cloning technology.

How the Scam Worked

Scammers used AI-powered voice synthesis to create a near-perfect clone of the German executive's voice, including his accent, speech patterns, and tone.
They called during business hours with a plausible business request — paying a supplier — rather than something obviously suspicious.
The urgency ("within the hour") prevented the CEO from verifying through other channels.
The amount was large enough to be profitable but small enough to seem like a normal business transaction.

Red Flags That Were Missed

The request demanded immediate action with no time to verify

The payment was to an unfamiliar bank account, not the usual supplier account

The call came from an unverified phone number, not the boss's known direct line

No written confirmation (email) accompanied the verbal request

What You Should Learn From This

AI can now clone voices convincingly — a familiar voice alone is not proof of identity.

Any urgent request for money transfer should be verified through a separate communication channel (email, text, or calling back on a known number).

Companies should have multi-person approval processes for large transfers.

If something feels rushed, that's exactly when you should slow down.

Outcome

The money was never recovered. The case became one of the first widely reported incidents of AI-powered voice fraud and prompted many companies to implement dual-approval processes for wire transfers.
