AI Phishing Detector
Phishing emails no longer look like phishing emails. That's the whole point.
The dangerous ones don't look dangerous
Modern phishing attacks are sophisticated enough to pass basic spam filters, use legitimate-looking domains registered days before the attack, and replicate the visual design of genuine communications accurately enough to fool recipients who are paying attention.
The old signals — spelling errors, generic greetings, obvious fake domains — are increasingly absent from well-executed attacks. The FBI's IC3 received over 300,000 phishing complaints in the most recent annual report, making it the most reported cybercrime category by volume.
The attacks that cause the most financial damage are the ones that don't look like attacks.
