Abstract

This document generally relates to systems, method, and other techniques for identifying and interfering with the operation of computer malware, as a mechanism for improving system security. Some implementations include a computer-implemented method by which a computer security server system performs actions including receiving a request for content directed to a particular content server system; forwarding the request to the particular content server system; receiving executable code from the particular content server system; inserting executable injection code into at least one file of the executable code; applying a security countermeasure to the combined executable code and executable injection code to create transformed code; and providing the transformed code to a client computing device.
