Cybersecurity threats in 2026 are qualitatively different from those of even three years ago. The widespread adoption of AI tools by criminal actors has dramatically elevated the sophistication of attacks that were previously detectable by vigilant users.
AI-generated phishing emails are now personalised, grammatically perfect, and contextually plausible โ often incorporating genuine details about the target sourced from social media and previous data breaches. The old red flags โ poor grammar, generic greetings, implausible scenarios โ have largely disappeared.
The minimum baseline for personal cybersecurity includes: a password manager with unique passwords for every account; multi-factor authentication on all important accounts (preferably using a hardware key or authentication app, not SMS); regular monitoring of your email at haveibeenpwned.com; and healthy scepticism about any urgent financial request.
The weakest link in cybersecurity is almost never the technology. It is the human. And AI has now made attacking the human far easier than attacking the machine.
For businesses, the most serious emerging threat is "deepfake CEO fraud" โ AI-generated voice and video clones of executives used to authorise fraudulent wire transfers. Several companies have lost millions to this attack vector in 2025-26.
