Abstract

Tracking scripts can use the sourceURL directive to mask their origin from developer tools and tools that use the same JS call stack and network stack information. Firefox and Chromium appear to be affected. Firefox 78 now includes a preference to disable this behavior. This short paper describes the effect when using the OpenWPM measurement platform along with details of discovery.
