Abstract
A technique for local proxy detection includes monitoring outbound traffic from the endpoint with remote network addresses outside the enterprise network, detecting use of a secure communication protocol with a request from the endpoint to one of the remote network addresses, identifying a plaintext network address within the request, and in response to identifying a plaintext network address in the request, initiating remediation of a potentially malicious local proxy on the endpoint.
