AI Is Changing Cyber Security Threats: Is Your Business Prepared?
An email asking you to update a supplier's bank details. A message that appears to come from your managing director. A phone call pushing your accounts team to make an urgent payment. These are familiar business scams, but AI is giving criminals more ways to make them convincing.
For small businesses across North Wales, the priority is understanding what is changing and putting sensible protection in place. You do not need to become an AI expert to make your business harder to target.
How is AI changing cyber threats?
The National Cyber Security Centre (NCSC) assesses that AI will almost certainly make elements of cyber attacks more effective and efficient, increasing the frequency and intensity of threats. Its 2025 Annual Review describes attackers using AI to improve existing techniques, including social engineering and researching software weaknesses.
In everyday terms, criminals can use AI to help produce convincing messages, adapt their wording and reduce the effort needed to approach potential victims. Poor spelling is no longer a reliable way to separate a scam from a genuine request. A polished message can still lead to a fake login page or a fraudulent payment.
A familiar voice is not proof of identity
The UK Government's Fraud Strategy 2026–2029 identifies voice cloning and deepfakes among the AI tools criminals are adopting. These can be used to impersonate trusted people and make fraudulent requests more credible.
For example, imagine someone claiming to be your director asks for an urgent transfer while they are away. That is a hypothetical scenario, but it illustrates why payment approval should depend on a reliable process rather than how familiar a message sounds.
Confirm unusual payments or changes to bank details using contact information you already trust. Do not rely on a telephone number supplied in the request. Where appropriate, require a second person to approve the transaction. Urgency, secrecy or pressure to bypass normal checks should prompt your team to pause.
Why small businesses need to take this seriously
A small business can still hold valuable customer information, supplier details, email accounts and financial records. Criminals do not need to recognise your company name for a compromised account to be useful to them.
Consider what would happen if your team could not access its email, orders or invoicing for a day. Or if a customer received a fraudulent payment request from your genuine email account. Cyber security protects your ability to operate, as well as your information and reputation.
Whether you run a professional practice in Ruthin, an office in Wrexham or a manufacturing business in Deeside, the starting point is the same: identify the systems your business depends on and check how they are protected.
Using AI at work creates another responsibility
AI tools can help with drafting, summarising and everyday administration. Before staff use them with business information, agree which tools are approved and what data they may receive.
Customer records, staff details, contracts and commercially sensitive documents need particular care. Understand the provider's terms, retention arrangements and security settings before uploading them. Do not assume every AI service handles information in the same way.
Give staff simple rules they can follow, including when to remove identifying details and when to seek approval. Check AI-generated output before acting on it, especially where it affects customers, payments or important business decisions.
Five practical steps to strengthen your protection
1. Secure the accounts your business relies on
Prioritise email, banking and services holding customer or staff data. Use passkeys where supported. Where passwords are used, make them strong and unique and enable multi-factor authentication. Review permissions and remove access when employees leave.
2. Keep devices and software supported and updated
Apply security updates to computers, phones and business software. Check that older equipment still receives support, and maintain suitable protection against malware. Updates close known weaknesses that attackers may try to exploit.
3. Make reporting suspicious requests easy
Show your team examples of fraudulent invoices, fake login pages and impersonation attempts. Encourage people to ask for help without embarrassment. Agree who they should contact if they are unsure or have already clicked a suspicious link.
4. Back up important data and test recovery
Identify what you would need to restore to get the business functioning again. Protect your backups, keep a copy separated from everyday systems and check that you can recover the information you need. A backup is only useful if it works when required.
5. Prepare a simple response plan
Record who to contact if an account is compromised or a payment appears fraudulent. Keep your IT support and bank contact details accessible outside your usual email system. If money has been transferred to a scammer, contact your bank immediately and alert your IT support.
Where does Cyber Essentials fit?
Cyber Essentials is a Government-backed scheme focused on five technical controls: firewalls, secure configuration, security update management, user access control and malware protection. Cyber Essentials Plus adds independent technical testing.
These controls provide a useful foundation against common cyber threats. Certification is not a guarantee against every attack, and businesses still need staff awareness, sensible payment procedures and clear rules for AI use. Together, these measures make security part of everyday operations.
