Patent attributes
A computing device comprising a secure browser extension for a web browser monitors for satisfaction of one or more operating conditions to identify whether one or more unauthorized applications are intercepting web browser communications. Based on satisfaction of at least one operating condition, the secure browser extension of the computing device sends an HTTPS request to a known service via the web browser. The secure browser extension receives an HTTPS response to the HTTPS request via the web browser. The secure browser extension determines whether the certificate included in the HTTPS response is trusted by the secure browser extension. Based on determining the certificate is not trusted, the secure browser extension terminates the web browser session and generates a notification for display at the computing device that indicates web browser communications are compromised.
