Phishing is a name derived from the notion of “fishing for information”, and “phreaking”. It is a simple concept whereby fraudsters attempt to trick would-be victims into disclosing sensitive personal details — their bank account details are often particularly attactive — so that the attacker may then exploit the information gathered to masquerade as the victim, often to access their online bank account. Netcraft first launched its anti-phishing system in 2005 which carefully validates community-reported phishing sites before blocking the attack. Well over 35.2 million unique phishing sites have been detected and blocked by Netcraft’s system to date [August 2017]. Netcraft’s phishing feed is used in all major web browsers and it is also licensed by many of the leading anti-virus, content filtering, web-hosting and domain registration companies. At least three separate third-party studies have found Netcraft’s anti-phishing blocklist to be the most comprehensive feed available.
