Cybersecurity: AI vs AI and smart defence in an AI-powered world

1. AI-driven attacks are the dominant risk

Artificial intelligence is reshaping not just how systems are built - but how they are attacked.

• Attackers now use AI to automate reconnaissance, generate phishing messages, and craft deepfake content that’s harder to spot and more convincing than ever before.
• Sophisticated AI bots can blend into normal activity, bypassing traditional detection systems.
• Emerging threats include agentic AI malware - autonomous systems that find vulnerabilities and adapt attack patterns without human oversight.

What you should do: Implement layered security with AI-powered monitoring, train teams to recognize AI-enhanced fraud, and enforce strict access governance.

2. Social engineering and deepfakes strike harder

Gone are the days when phishing was easily recognizable.

• AI enables attackers to craft highly personalized emails, calls, and messages using information gathered from social media, electoral register, and other publicly available databases - convincingly impersonating trusted contacts.
• Deepfakes - realistic fake videos or voice clips - are being used to deceive employees and executives.

Tip: Always pause and verify externally if a request seems urgent or unusual, even if it looks legitimate.

3. Internet of Things (IoT) Devices Are Easy Targets

Not just phones and laptops - everyday devices like smart TVs, routers, thermostats, and even coffee machines can be breach points.

• Millions of devices with poor security are being hijacked into botnets or used to infiltrate home and office networks.

What to change: Replace default passwords, keep device software updated, and only buy products with clear security support.

4. Real-World Breaches and Systemic Risks

Cyber-attacks are no longer theoretical - they’re happening now.

• The European Commission experienced a breach of its mobile management system, exposing staff contact details.
• Critical infrastructure and enterprise supply chains are under constant threat, especially from sophisticated nation-state or organised groups.

Lesson: Anyone managing data, infrastructure, or user access - from small firms to government bodies - must assume they’re a potential target.

5. Identity and Access Are the New “Perimeter”

Traditional network perimeters are disappearing.

• Identity credentials and access tokens are often the weak link - attackers go after people, not just machines.
• Multiple breaches start with stolen or reused passwords, or compromised authentication systems.

Best practice: Use multi-factor authentication, strong password policies, privileged access monitoring, and zero-trust principles across the board.

6. Ransomware and Fraud Still Rampant

Despite new tech, old-school crime persists:

• Ransomware continues to cost millions and disrupt services.
• Cyber-enabled fraud, fuelled by AI and social engineering, is becoming a top concern for CEOs and executives.

Protect yourself: Regular backups, segmentation of data, and fraud monitoring tools are essential.

7. Regulation and Governance Are Catching Up

More laws and guidelines are emerging globally to make organisations more accountable.

• Regulatory frameworks worldwide are tightening, and more companies are increasing cybersecurity budget and staffing.
• Boards and executives are increasingly held liable for compliance failures.

Advice: Build compliance into your security strategy early - it’s cheaper and safer than reacting after a breach.

Closing Thought

The cybersecurity landscape in 2026 is dynamic, complex, and increasingly automated. Attackers are weaponising the same technologies that are transforming our lives. But informed organisations and individuals - by understanding trends like AI-driven attacks, social engineering, identity risks, and IoT vulnerabilities - can stay ahead of the curve.
