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 installed on the computing device. Based on satisfaction of at least one operating condition, the secure browser extension of the computing device sends an HTTP request to a known service via the web browser. The secure browser extension receives a response to the HTTP request via the web browser. The secure browser extension determines whether the received response is an HTTP response (e.g., from an unauthorized application) or a non-HTTP response (e.g., from the known service). Based on determining the received response is an HTTP response, 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.
