Small businesses can be affected by phishing, stolen passwords and ransomware. Here are five areas to review, along with steps that can reduce the risk.

1. AI-Powered Phishing Attacks

Phishing emails are no longer easy to spot from spelling mistakes alone. Cybercriminals can now use generative AI to draft convincing, personalised emails that copy the tone of suppliers, customers or senior staff.

The Fix: Staff training is your first line of defence. But you also need technical safeguards. We recommend implementing strict email security protocols like SPF, DKIM, and DMARC to prevent domain spoofing.

The capability is also moving beyond convincing messages. Read what recent AI-agent security incidents mean for small-business websites and the practical checks worth making now.

2. Ransomware-as-a-Service (RaaS)

Ransomware can lock you out of files and systems. Review who has access, how updates are applied and whether backups can be restored independently.

The Fix: Set up off-site, immutable backups that cannot be encrypted by the same malware. Our Cloud Migration services can include backup planning, recovery checks and safer access controls.

3. Supply Chain Attacks

You might be secure, but what about your accountant or your logistics provider? Hackers are increasingly targeting smaller suppliers to gain access to larger networks. If your systems are connected to insecure third parties, you are at risk.

The Fix: Audit your suppliers. And ensure you have "Zero Trust" policies in place within your own network, so if one account is compromised, the attacker can't move freely through your system.

4. IoT Vulnerabilities

From smart thermostats in your office to connected manufacturing equipment, the Internet of Things (IoT) is expanding the attack surface. Many of these devices have poor default security and are rarely updated.

The Fix: Segregate your network. Your smart fridge shouldn't be on the same WiFi network as your payroll system. A proper network architecture review can identify these weak points.

5. Insider Threats (Accidental)

Not all threats are malicious. A tired employee clicking the wrong link or sending a sensitive file to the wrong person is still a major cause of data breaches. With hybrid working now the norm in MK, the risk of data leaking outside the office is higher.

The Fix: Implement Data Loss Prevention (DLP) tools and ensure your Microsoft 365 or Google Workspace environment is configured correctly to flag sensitive data transfers.
