Abstract

Disclosed herein is a technique for detecting potential phishing attacks by monitoring outbound web traffic from an endpoint, along with inbound electronic mail traffic addressed to a user of the endpoint. With this information, a search can be performed for possible sources in the web traffic of a request for a hyperlink located in the inbound mail traffic, and when no source is located, phishing remediation can be performed, including restrictions on access to the hyperlink at an endpoint operated by the user.
