Is checking for typos still good phishing advice?

No — it's now counterproductive. AI writes flawless phishing emails, so people trained to look for typos give a clean, well-written email a pass it hasn't earned. Verification rules replaced inspection rules.

AI Phishing: Why "Look for Typos" Is Now Dangerous Advice

Q: How do you spot an AI-generated phishing email?

You can't reliably spot it by reading it — AI phishing is clean, personal, and grammatically perfect. Instead, judge emails by what they ask, not how they're written: any request involving money, credentials, or urgency gets verified through a second channel before you act.

Quick answer: you can no longer spot phishing by reading it. AI-written phishing is clean, personal, and grammatically perfect — so the old "look for typos and bad grammar" rule now actively hurts you: it teaches you to trust exactly the emails attackers send. The replacement: judge emails by what they ask, not how they're written, and verify every sensitive request through a second channel.

For twenty years, the advice worked: bad grammar, weird greetings, "Dear Costumer" — delete.

Then attackers got the same writing assistant you use for your newsletters.

Why the Old Advice Backfires

The typo rule didn't just become useless — it became a vulnerability. If your mental spam filter is "sloppy = scam, polished = safe," then a polished scam sails straight through. You've been trained to trust the exact thing AI mass-produces.

And mass-produce it does. Security vendors tracking 2025 phishing volume report attack cadence measured in seconds, with most phishing URLs generated unique per campaign — never seen before, which also defeats pattern-matching filters. The same personalization engine writes a different perfect email for every recipient, scraped from your LinkedIn, your site, your last launch.

The New Rules (Verification Beats Inspection)

Judge the ask, not the prose. Money, credentials, gift cards, "updated banking details," login links, urgent attachments → the content of the request is the red flag, regardless of how legitimate the email looks.
Verify through a second channel. Email from your payment processor? Open the site yourself — never via the email link. "Client" changing payout details? Call the number you already have.
Treat urgency as hostile. "Within 24 hours or your account closes" is a pressure tactic. Real companies survive you taking ten minutes to check.
Display names lie. Check the actual sender domain — and assume even that can be spoofed. The second channel is what saves you, not sender inspection.
MFA everywhere — but don't worship it. Modern phishing kits can steal authenticated session cookies and ride past MFA. MFA is a seatbelt, not immunity; the verification habit still applies.

One more upgrade: the same playbook now arrives by phone. When the "email" calls you with a familiar voice, that's voice cloning taking the same scam to the phone — same defense, different channel.

📌 ACTION STEP
→ Adopt the rule today: every money/credential request gets second-channel verification
→ Tell your VA / team / family the typo rule is dead
→ Bookmark your critical logins — never reach them from email links
