Adobe’s software (Photoshop, Premiere Pro, After Effects, Illustrator, etc.) constantly checks in with several licensing and validation servers.

This information is for educational purposes. Circumventing paid software licensing violates Adobe’s Terms of Service. Always purchase a valid license for commercial use. This guide focuses on privacy and network control for legitimate license holders. The Top Adobe Domains to Block: The "Hosts File Block List" Gold Standard After analyzing network traffic from Adobe Creative Cloud apps for years, the security and "zero-day" community has compiled a definitive list.

If you are a legitimate Creative Cloud subscriber who simply wants privacy, the list above will stop 90% of outbound telemetry without breaking app functionality. If you are looking to bypass subscription checks, the hosts file alone is no longer sufficient—Adobe’s security has evolved. This guide focuses on privacy and network control
