Symantec has relaunched an anti-phishing fraud service it acquired as part of its purchase of WholeSecurity last year.
Symantec said that eBay, Google, Yahoo, RSA Security and Wells Fargo would participate in the data sharing group, although Microsoft is no longer involved.
The relaunched Phish Report Network would provide a vetted and constantly updated database of fraudulent websites, said Symantec.
Companies could use the database to protect their networks, and security software suppliers could use the service to update the blacklists within their products.
Similar phishing site alert services already exist. There is CipherTrust's PhishRegistry.org, and the non-profit and industry-supported Anti-Phishing Working Group (APWG).
Companies and organisations that contribute data to the Phish Report Network will get free access to the database. Others will be charged to help cover the costs of running the database.
