Use a third-party firewall (like Little Snitch on macOS or SimpleWall on Windows) to block specific Adobe processes. Unlike the Hosts file, firewalls can block by and certificate hash , not just domain.
The Adobe Hosts File Block List is a collection of network entries that users add to their operating system's hosts file to block connections to Adobe's activation, licensing, and telemetry servers.

While the intended use case is to mitigate intrusive licensing pop-ups in unlicensed Adobe software, the technique has also proven useful for legitimate users seeking to curb unwanted telemetry and analytics. It has further gained relevance as a countermeasure after Adobe was discovered in 2026 to be secretly modifying users' hosts files to track Creative Cloud installations.
