- If you get phishing e-mail, go the web sites and enter false data. Make up everything -- name, sign-on name, password, credit card numbers, everything. Instead of one million messages yielding 100 good replies, now the phisher will have one million messages yielding 100,000 replies of which 100 are good, but WHICH 100?
This technique kills phishing two ways. It certainly increases the phishing labor requirement by about 10,000X. But even more importantly, if banks and e-commerce sites limit the number of failed sign-on attempts from a single IP address to, say, 10 per day, theft as an outcome of phishing becomes close to impossible.
