AI is changing the cybersecurity threat model

Artificial intelligence is becoming part of everyday software, but it is also changing how attackers and defenders operate. AI can help security teams analyze large amounts of information, while attackers can use automation to produce convincing messages, discover targets and scale repetitive tasks.

Phishing is becoming harder to spot

Traditional phishing messages often contained obvious spelling mistakes or unusual formatting. Generative AI can make scam messages more polished and personalized. That means users should rely less on grammar and more on verification: check the sender, avoid unexpected links and confirm sensitive requests through a separate channel.

AI systems have their own attack surface

Organizations also need to secure the AI applications they build. Risks can include prompt injection, unauthorized access to connected tools, sensitive information being exposed in model inputs, insecure plugins and excessive permissions.

An AI assistant connected to company documents should not automatically have permission to modify payroll, transfer money or change production systems. The principle of least privilege is just as important for AI agents as it is for traditional software.

Mobile security still matters

Phones are increasingly used for authentication, payments, work and personal communications. Google's 2026 Android updates include security improvements alongside AI features, reinforcing an important point: more capable devices also need stronger security controls.

A practical security checklist

  • Use multi-factor authentication wherever available.
  • Keep operating systems and browsers updated.
  • Review which AI applications can access company or personal data.
  • Limit agent permissions to the minimum required task.
  • Require confirmation for high-impact actions.
  • Back up important information independently.

The security lesson for 2026 is not to avoid AI. It is to treat AI as software with real permissions, data access and failure modes that need to be managed deliberately.
