"Spear-phishing is much harder to detect than phishing. Bogus e-mail messages and Web sites not only look like near-perfect replicas of communiqu�s from e-commerce companies like eBay or its PayPal service, banks or even a victim's employer, but are also targeted at people known to have an established relationship with the sender being mimicked."
