Deepfake fraud: what it is and how to stop it

Criminals use cloned voices and synthetic video to pose as people you trust and get money or access moved. There is no patch to install. The defence is a set of checks that never accept a face or a voice as proof.

UK Finance reports 2025 fraud figures[4]

Criminals stole £1.28 billion through payment fraud in 2025. UK Finance's release does not break out losses from deepfakes.

Cyber Security Breaches Survey 2025/2026 published[6]

It found 12% of businesses reported impersonation breaches or attacks, and that phishing was the most common type of attack.

Government publishes its account of the framework[2]

The Government Office for Science described tests of detection tools against impersonation, fraud and non-consensual images, with results intended to set industry standards.

The full timeline

This site follows one question for UK decision makers: how real is deepfake fraud, and what should an organisation change this month? It draws on government, UK Finance, NCSC and police guidance, one survey of security leaders and one well-documented case.

Where the risk sits

The risk is not a flaw in your software. It sits in the moment someone acts on a request because it looked and sounded right.

A fake voice or face on a call

An employee at Arup was tricked into sending about HK$200m (roughly £20m) during a video conference with people posing as senior officers [1]. The firm described the call as using synthetic voices and pictures, and said its own systems were untouched [1]. The full story is in the fake video meeting scam.

A cloned voice by phone

Report Fraud describes criminals generating fake audio that imitates someone you know or trust, then claiming an urgent situation and asking for a payment [9]. See voice cloning scams.

More fakes in circulation

The government estimates about 8 million deepfakes were shared in 2025, against about 500,000 two years earlier [2]. It says the rise has increased the risk of scams [2].

The UK picture

What the figures can and cannot say

UK Finance reports that criminals stole £1.28 billion through payment fraud in 2025, up 4% [4]. Its release does not give a separate figure for deepfakes, so nobody can say from that report how much of the total they caused [4].

A Gartner survey of security leaders, reported by The Register, found 44% had seen at least one deepfake audio call against staff [7]. Of those, 6% led to business interruption, financial loss or lost intellectual property [7]. Treat that as a signal, not a UK measurement: the article does not state how many people were surveyed [7].

First move

Find the single process where a believable request could release money or access, and attach a confirmation step that uses contact details you already hold. The NCSC advises checking important requests by a second type of communication [8].

Quick answers

Questions people ask

What is deepfake fraud?

It is fraud that uses a fake voice, image or video to impersonate someone you trust and get money or access. The UK government says criminals use deepfakes to trick people into paying money[2]. In the Arup case, the people on a video call were fakes[1].

How did the Arup deepfake fraud work?

A worker at Arup transferred about HK$200m (about £20m) during a video conference with people posing as senior officers[1]. The firm stated that no internal system of its own was compromised, and that synthetic voices and pictures were involved[1].

Can a cloned voice really fool staff?

Report Fraud says fraudsters generate fake audio imitating someone you know or trust and claim an urgent situation to get a payment[9]. Gartner's survey found 44% of security leaders had seen at least one deepfake audio call against staff[7].

How common is deepfake fraud in the UK?

No UK source gives a reliable count. UK Finance reported £1.28 billion stolen through payment fraud in 2025 but did not separate deepfakes[4]. The government estimates about 8 million deepfakes were shared in 2025[2].

Know your exposure

Not sure you are protected?

Deepfake fraud is stopped by decisions about who may release money or access and how a request is confirmed. A virtual CISO helps leaders set those rules and have them tested, without a full-time hire.
