Abstract: Embodiments are directed to detecting and preventing phishing attacks. In one scenario, a computer system accesses a message and analyzes content in the message to determine whether a link is present. The link has a link destination and at least some text that is designated for display in association with the link (i.e. the anchor), where the text designated for display indicates a specified destination. Then, upon determining that a link is present in the message, the computer system determines whether the link destination matches the destination specified by the text designated for display and, if it determines that the destination specified by the text designated for display does not match the link destination, the computer system flags the message to indicate that the message includes at least one suspicious link.
