phishing (n.)

"fraudulent attempt to obtain sensitive information such as usernames, passwords and credit card details by disguising oneself as a trustworthy entity in an electronic communication" [Wikipedia], by 2000 (many sources cite usage from 1995 among hackers, and the thing itself was active by then); an alteration of fishing (n.); perhaps by influence of phreak and the U.S. rock band Phish, which had been performing since 1983.
