The Hidden Hand: Why Adobe is Surreptitiously Modifying Your System Hosts File

The report details Adobe Creative Cloud surreptitiously adding entries to the system hosts file on Windows and macOS so a non-resolving domain (detect-ccd.creativecloud.adobe.com) points to a local IP; when the Adobe website requests an image at that domain, the mapping confirms the software is installed. This hosts-file manipulation bypasses modern browser restrictions for local resource access, may be reinstated by updates, and the suggested mitigation is blocking the domain at the router level.
