Frequently Asked Questions
Is this a phishing detector or sniff-test?
Sniff-test. Heuristic pattern matching, not a database lookup. Scams that pass our patterns may still be phishing — when in doubt, don't click.
Common phishing patterns?
Typosquatting (paypa1.com vs paypal.com), unfamiliar TLDs (.tk, .ml), excessive subdomains, IP addresses, encoded characters, "urgent" wording in URL.
What if it looks legit but I'm unsure?
Don't click. Open the legitimate site in a new tab manually (type URL). Log in normally and check for the alleged urgent issue. 99% of "urgent" emails are phishing.
