Deepfake Fraud: What UK Finance and HR Teams Must Do Now

Deepfake fraud is becoming a serious business risk. What should UK finance and HR teams do?

Finance and HR teams should treat every high-risk request with caution, even if it appears to come from a trusted executive. Deepfake fraud can manipulate voices, videos and emails to authorise payments or access sensitive information. Businesses should verify requests through trusted communication channels, enforce multi-level approval processes, provide regular employee awareness training and maintain an incident response plan. A verification-first approach helps reduce the risk of financial loss, data breaches and business disruption.

What is deepfake fraud?

Deepfake fraud is a cybercrime technique that uses AI-generated audio, video or images to impersonate real people and deceive employees. Criminals use these convincing impersonations to request urgent payments, obtain confidential information or bypass internal security controls. 

These attacks often work alongside phishing and social engineering tactics, making them difficult to identify. Organisations that understand the Importance of Cybersecurity and implement strong verification procedures are better equipped to defend against this rapidly growing threat.

Why finance and HR departments are common targets

Cyber criminals tend to target departments that can authorise payments or access valuable personal information.

Finance teams routinely process supplier invoices, payroll, expense claims and bank account changes. HR teams manage employee records, recruitment, salary information and identity documents. These responsibilities make both functions attractive targets.

Common scenarios include:

• A cloned voice requesting an urgent bank transfer.
• A fake video meeting where a senior executive instructs finance staff to make a confidential payment.
• A fraudulent job applicant using manipulated video during an online interview.
• Requests to change payroll or supplier banking details using convincing impersonation techniques.
• Emails that appear genuine because they are supported by realistic audio or video messages.

Many organisations have robust technical security measures, but criminals increasingly exploit human decision-making instead of software vulnerabilities.

How deepfake fraud affects UK businesses

The impact extends beyond financial loss. A successful attack can interrupt business operations, damage customer confidence and create regulatory obligations where personal data is compromised.

Potential consequences include:

• Unauthorised payments.
• Exposure of employee or customer information.
• Payroll fraud.
• Identity theft.
• Reputational damage.
• Increased compliance and investigation costs.

If an incident leads to the compromise of personal information, organisations may also need to follow relevant reporting and response obligations under UK data protection requirements.

Preparing for these situations is far easier than reacting after an attack. Businesses that have already reviewed their response plans through Data Breach Resilience: Building Stronger Defences in an Era of Cyber Threats will generally be in a stronger position to minimise disruption.

Warning signs that a request may involve a deepfake

Deepfakes continue to improve, but they are not always flawless. Employees should be encouraged to slow down and verify unusual requests rather than acting immediately.

Watch for signs such as:

Unexpected urgency

Fraudsters frequently create pressure by claiming a payment or decision must happen immediately.

Requests that bypass normal approval processes

Any instruction asking employees to ignore established procedures deserves additional scrutiny, even if it appears to come from a senior executive.

Minor inconsistencies

While modern deepfakes can be highly convincing, there may still be subtle differences in facial movements, voice patterns, lip synchronisation or background noise.

Unusual communication channels

An executive who normally communicates through Microsoft Teams may suddenly request approval through a personal messaging application or unfamiliar phone number.

Requests involving confidential information

Unexpected requests for payroll records, identity documents or employee information should always be independently verified.

Practical steps finance teams should take today

Finance departments remain one of the primary targets because payment fraud can generate immediate financial returns for criminals.

Several practical controls can significantly reduce risk.

Never rely on voice or video alone

A convincing voice should never be considered proof of identity. Sensitive financial instructions should always be confirmed through a separate, trusted communication channel.

Strengthen payment approval controls

Large or unusual payments should require multiple levels of authorisation. Dual approval processes make it much harder for a single impersonation attempt to succeed.

Verify changes to banking information

Supplier and payroll account changes should always be confirmed using previously verified contact details rather than information provided in the request itself.

Record and review unusual requests

Maintaining records of attempted fraud helps identify emerging patterns and supports future awareness training.

As threats continue to evolve, organisations should regularly review security controls through A Comprehensive Guide to Cybersecurity Assessments to identify weaknesses before they can be exploited.

Implement independent verification procedures

Finance teams should establish clear verification procedures for any request involving money, supplier details or confidential financial information.

Verification should include:

• Calling a known company contact using an existing phone number.
• Confirming requests through an approved internal communication platform.
• Checking whether the request follows established financial policies.
• Escalating unusual instructions before taking action.

Building verification into everyday processes helps reduce the chance of employees making decisions under pressure.

What HR teams should do to reduce deepfake risks

HR professionals handle a significant amount of sensitive personal information, making them attractive targets for identity fraud and impersonation attacks.

Recruitment, onboarding, payroll administration and employee record management all present opportunities for cyber criminals if verification processes are weak.

Verify candidate identities during recruitment

Remote recruitment has become common across many UK organisations, but it also creates new challenges.

Where appropriate, HR teams should:

• Request official identity documents through secure channels.
• Verify candidate details before issuing employment contracts.
• Be cautious if video quality appears unusually distorted or if facial movements seem inconsistent.
• Confirm qualifications and employment history using independent sources.

Deepfake technology can imitate facial expressions and voices, but it cannot replace proper identity verification.

Protect employee information

Employee records contain valuable personal data that criminals can exploit for identity theft and financial fraud.

Access to HR systems should follow the principle of least privilege, ensuring employees only have access to information necessary for their role.

Sensitive documents should never be shared simply because a request appears to come from a senior manager.

Establish clear approval processes

HR requests involving payroll changes, employment contracts or personal information should require documented approval.

For example:

• Changes to employee bank details should always be independently verified.
• Requests for personnel records should follow internal authorisation procedures.
• Executive requests for confidential information should be confirmed using an alternative communication method.

These controls reduce reliance on trust and instead create repeatable, secure processes.

Employee awareness remains one of the strongest defences

Technology alone cannot stop deepfake fraud. Employees must understand how these attacks work and feel confident questioning unusual requests.

Regular awareness sessions should include realistic examples that reflect situations employees may encounter within finance, HR and leadership teams.

Training should cover:

• Common deepfake fraud techniques.
• Business email compromise.
• Social engineering tactics.
• Verification procedures.
• Reporting suspicious activity quickly.

Organisations that invest in ongoing education are generally better prepared than those relying solely on technical controls. Developing a security-first mindset across departments is equally important, which is why Building a Culture of Cybersecurity should be viewed as an ongoing business objective rather than a one-time initiative.

How organisations should respond to a suspected deepfake attack

Even well-prepared organisations may encounter attempted impersonation attacks. Having an established response plan helps minimise disruption and supports a faster recovery.

If a deepfake attack is suspected:

1. Pause any payment, payroll or data-sharing activity immediately.
2. Verify the request through trusted contact methods.
3. Inform internal IT or cyber security personnel.
4. Preserve relevant emails, recordings and communication logs.
5. Assess whether any personal or financial information has been disclosed.
6. Review existing controls to identify how the attempt occurred.
7. Update employee guidance if new attack methods are identified.

Practising these procedures through regular exercises helps ensure staff know how to respond under pressure.

Frequently asked questions

Can deepfake fraud affect small and medium-sized businesses?

Yes. While large organisations often receive more public attention, small and medium-sized businesses are also targeted. Criminals typically focus on organisations with weaker verification processes rather than company size.

Can employees detect every deepfake?

No. Some deepfakes are highly convincing and may be difficult to identify through visual or audio cues alone. This is why verification procedures are more reliable than relying on instinct.

Is email still used in deepfake attacks?

Yes. Deepfake audio or video is often combined with phishing emails, business email compromise or messaging platforms to make fraudulent requests appear more credible.

Which departments face the greatest risk?

Finance, HR, procurement, payroll and executive leadership teams are among the most frequently targeted because they handle payments, confidential information and business-critical decisions.

Final thoughts

Deepfake fraud is changing how organisations need to think about trust. Familiar voices, recognisable faces and convincing video calls can no longer be treated as proof of identity on their own.

For UK finance and HR teams, the priority should be creating verification processes that remain effective even when sophisticated impersonation techniques are used. Multi-person approvals, independent verification, employee awareness and regular security assessments all contribute to a stronger defence against this growing threat.

As deepfake technology continues to evolve, organisations that combine practical security controls with informed employees will be far better positioned to protect their finances, personal data and business reputation. Rather than reacting after an incident, businesses should review their existing cyber security practices now and strengthen any areas where trust still outweighs verification.
