AI Phishing No Longer Has Typos. Here's How to Defend Against It

For years, the standard advice for spotting a scam email was simple: look for mistakes. Odd greetings, clumsy grammar, strange formatting. Staff were trained to spot the tells.

That advice is now out of date.

What changed

Generative AI tools let anyone write fluent, professional, personalised email in seconds, in any tone, in any language. An attacker can paste in a few details from your company website or a LinkedIn profile and produce a message that reads exactly like it came from your finance team, your vendor, or your boss.

The result: the quality of phishing went up while the cost of sending it went down. More attempts, each more convincing.

Why "just be careful" isn't a strategy

Asking employees to out-think a machine every single time is a losing plan. People are busy, distracted and trusting, which is normal and not a failing. A defense that depends on nobody ever making a mistake will eventually fail.

The better question is: what happens when someone clicks?

What actually works

1. Catch it before it arrives. Modern AI-driven filtering analyses sender behaviour, content and context, not just known-bad lists. Tuned properly, it stops the majority of malicious mail before a human sees it.
2. Quarantine instead of deliver. Suspicious-but-uncertain messages are held for approval rather than dropped in the inbox. The risky click simply never gets the chance to happen.
3. Protect the link at the moment of the click. Attackers often send a clean link, then switch the destination to something malicious after delivery. Checking links at click time closes that gap.
4. Require a second factor everywhere. Even a stolen password is useless without the second approval. App-based approval or passkeys are far stronger than text messages.
5. Make unapproved software unable to run. If a victim downloads a malicious file, zero trust application control means it never executes.
6. Teach one verification habit. Any request involving money, credentials or changed bank details gets confirmed through a second channel, like a call to a known number, regardless of how urgent it looks.

The mindset shift

Stop trying to make every employee a perfect detector. Build layers so that one human mistake doesn't become a business-ending event.
