The Anti-Phishing Working Group (APWG) is an international membership organization that seeks to eliminate fraud based on attacks from phishing and e-mail spoofing. These attacks hurt legitimate businesses as the attackers fraudulently use the identity of an established organization in their attack. And it hurts the victims who provide authentication information, thinking they are dealing with a trusted entity.
Through its web site, APWG provides information about current and historic attacks and provides a location for people to report new ones, sharing information with law enforcement when it's applicable.
The organization also works on prevention efforts, testing prevention tools and techniques; and educating people about ways to avoid being victimized. It offers a news feed and white papers as well as solid advice.
