In 2025, Belgian SMEs face a new kind of cyber threat: attacks driven by artificial intelligence (AI). Cybercriminals are using sophisticated AI tools to personalize phishing emails, automate malware and even mimic CEO voices. This evolution renders traditional security measures inadequate.

In this blog, we discuss how AI is being used by cybercriminals, why SMEs are particularly vulnerable and what concrete steps you can take to protect your business.

1. AI as a Weapon: The New Reality of Cyberattacks.

Cybercriminals are using AI to refine and automate attacks. According to Fortinet, 36,000 automated scans per second are performed worldwide, targeting vulnerabilities in systems such as Remote Desktop Protocols and IoT devices.

In addition, AI chatbots are being used to generate phishing emails that are grammatically perfect and difficult to distinguish from real communication. This evolution requires new detection strategies and increased vigilance.

2. Why SMEs Are Extra Vulnerable.

Belgian SMEs are an attractive target for AI-driven attacks. A study shows that 25% of Belgian small businesses have already fallen victim to a cyber attack. Limited resources and lack of specialized IT security make them especially vulnerable.

Moreover, many SMEs rely on digital tools without adequate security measures, making them an easy target for automated attacks.

3. Shadow AI: The Invisible Threat Within Your Own Organization

Employees are increasingly using AI tools without IT approval or oversight. This phenomenon, known as “Shadow AI,” can lead to data breaches and compliance issues. A recent survey shows that 23% of IT professionals reported instances where AI agents were tricked into revealing access information.

Recommendations:

• Establish clear guidelines for the use of AI within the organization.

• Conduct regular audits to identify unauthorized tools.

• Offer training on safe and responsible use of AI.

4. Zero Trust: A Necessary Strategy for SMEs.

The traditional security model, where everything within the network is considered secure, is outdated. Zero Trust is based on the principle of “never trust, always verify.” Every access attempt is monitored, regardless of location or user.

Advantages of Zero Trust:

• Restricts lateral movements of attackers within the network.

• Increases visibility and control over user activities.

• Improves regulatory compliance and compliance.

Implementation steps:

• Implement multi-factor authentication (MFA) for all users.

• Segment the network to restrict access to necessary resources.

• Continuously monitor all network activity and respond to anomalies.

5. AI as Defense: Use AI to Fight AI

Although AI is a threat, it can also be used as a defense tool. AI-driven security tools can detect anomalies, identify suspicious activity and automatically respond to threats.

Action items:

• Invest in AI-driven security tools that enable real-time monitoring and response.

• Train employees in recognizing advanced phishing attempts.

• Implement a zero-trust security model.

Conclusion

The rise of AI-driven cyber threats requires a proactive and informed approach. By implementing Zero Trust, regulating Shadow AI and using AI as a defense tool, Belgian SMEs can guard against this new generation of attacks.
