Why phishing is still a top risk
Phishing remains one of the most effective attack techniques because it targets people, not just systems. Attackers craft believable emails, texts, or pages to trick you into revealing credentials, clicking malicious links, or approving fraudulent actions. AI is changing both sides of this equation: attackers use generative models to write more convincing attacks, while defenders apply AI to detect subtle signals at scale.
What AI looks for when spotting phishing
Content signals
Modern systems analyse language patterns, unusual phrasing, sender-recipient relationships, and formatting inconsistencies. Machine learning models can flag messages whose tone or vocabulary closely matches known phishing templates even when the surface text is new.
Technical signals
AI models combine content checks with technical telemetry: mismatched domains, short-lived hosting, odd redirect chains, SPF/DKIM failures, and malicious attachments. These signals increase confidence that a message is malicious.
How AI is used in user-facing protections
Email providers, browsers, and security gateways use AI to prioritise and block high-risk messages. For users, this means:
- Fewer phishing emails reach the inbox.
- Clearer warnings when a suspicious page is opened.
- Automated link scanning and sandboxing of attachments.
What users should do to benefit from AI defenses
Use up-to-date services
Choose email and browser vendors that apply AI-based filters and regularly update their detection models. This reduces the chance that clever, AI-generated phishing slips through.
Keep device defenses current
Modern OS and browser updates improve both performance and security signals used by detection systems. Install updates promptly.
Combine AI with basic vigilance
AI reduces noise but doesn't remove the need for judgement. Look for unusual sender addresses, unexpected urgency, or requests for credentials. Follow practical advice in our guide on How to Spot and Avoid Phishing Attacks and Safe Browsing.
Limitations and risks of AI detection
AI can produce false positives and false negatives. Attackers adapt: generative models can craft targeted messages tuned to bypass naive detectors. That's why layered controls (filters, authentication, user training) remain essential.
Practical checklist
- Enable provider spam and phishing protection in your email settings.
- Use strong authentication (2FA or passkeys) for accounts that matter - see our 2FA guide and Passkeys explained.
- Train teams on verification steps for sensitive requests; validate out-of-band.
- Report suspected phishing to your provider so models can learn from new threats.
