New AI threats

OWASP LLM Top 10.

AI systems face new risks: prompt injection (manipulating inputs), data poisoning (corrupting training data), model theft and sensitive-data leakage. OWASP's LLM Top 10 is the reference.

Check your understanding

1. What is prompt injection?

2. What reference lists AI/LLM risks?

AI on the attack

Convincing phishing at scale, deepfakes for social engineering, and faster malware/exploit development. AI lowers the barrier for attackers.

AI on the defence

Detection & triage — ML spots anomalies and prioritises alerts in the SOC at machine scale.
Threat hunting — AI accelerates hunting across huge telemetry.
Automation — AI-assisted response speeds up containment.

The emerging threat landscape

Securing AI systems themselves (prompt injection, data poisoning) is now part of the defender's job. The defenders who understand AI — its power and its risks — will lead the next decade of cyber security.

Interview Intelligence

How this topic actually shows up in interviews — and how to demonstrate you understand it.

Why employers ask about this

AI fluency is fast becoming essential for cyber roles on both attack and defence.

Technical questions

How is AI used on both sides of cyber security?+

Attackers use it for phishing, deepfakes and faster exploits; defenders use it for detection, triage, hunting and response.

Behavioural questions

Show proactively learning emerging techniques on both sides.

Real-world scenarios

“Leadership ask how AI changes your threat model.”+

Expected answer: Explain AI-powered phishing/deepfakes raise the bar, AI aids detection at scale, and AI systems themselves need securing.

Frequently asked questions

How do attackers use AI?

For convincing phishing at scale, deepfakes for social engineering, and faster malware and exploit development.

How do defenders use AI?

For anomaly detection, alert triage, threat hunting and automated response at a scale humans can't match.

What new risks does AI itself introduce?

AI systems can be attacked via prompt injection and data poisoning, so securing them is now part of defence.
