PhishTank is an anti-phishing site.

PhishTank was launched in October 2006 by entrepreneur David Ulevitch as an offshoot of OpenDNS. The company offers a community-based phish verification system where users submit suspected phishes and other users "vote" if it is a phish or not.

PhishTank is used by Opera,[1] WOT,[2] Yahoo! Mail, Mcafee, APWG, CMU, ST Benard, Mozilla, Kaspersky, Firetrust, Officer Blue, FINRA, Message Level, SURBL, Sanesecurity for ClamAV,[3] Career Builder, Site Truth, Avira,[4] C-SIRT,[citation needed] and by PhishTank SiteChecker.[5][6]

PhishTank data is provided gratis for download or for access via an API call, including for commercial use, under a restrictive license.

In 2018, it was announced that PhishTank will be rebuilding the website, with new features and functionality. This work will begin in 2019.[7]
