SpyBuster is a Mac security and privacy app that helps users identify and block app and website connections to servers in Russia and Belarus.
What is SpyBuster?
SpyBuster is a macOS security and privacy app created to help users see whether apps and websites connect to servers in Russia or Belarus, then block connections they do not trust. It was built by MacPaw Labs LTD as an on-device tool focused on network awareness and data protection. The app combines static analysis, which highlights apps with ties to those regions, with dynamic analysis that monitors live connections and shows connection history while apps are running. Users could review potentially risky traffic, filter for compromised connections, and add endpoints to a deny list. SpyBuster was offered as a free Mac utility and was later expanded to other platforms, but support and distribution ended on July 1, 2026.

- Identify apps associated with servers in Russia or Belarus

Safety overview
Status: Mostly safe
SpyBuster is a legitimate security utility from MacPaw Labs LTD, and its network-monitoring behavior is consistent with its purpose. Because it inspects and can block app and website connections, users should expect network-related permissions and security prompts. Support and distribution ended on July 1, 2026, so the app no longer receives updates. If you still use it, review any network permissions it has and keep in mind that an unsupported security tool may become less reliable over time as macOS and online services change.
Recommendation: Keep SpyBuster only if you still actively rely on its connection-monitoring workflow and understand that it is no longer maintained. If you do not use it, removing it is a reasonable cleanup step and should only affect SpyBuster's own monitoring and blocking features.
