A computer-implemented method for reducing phishing attacks that employ malicious websites is provided. The computer-implemented method includes gathering information about potentially malicious websites from a plurality of sources. The computer-implemented method also includes reducing the number of potentially malicious websites gathered; thereby creating a malicious website database that tracks at least a subset of the potentially malicious websites. In addition, the computer-implemented method includes generating a malicious website blacklist from the malicious website database, each website in the malicious website blacklist satisfying inclusion criteria, wherein the malicious website blacklist is employed to decide whether an access request to a given website is permitted.
