Is anonymoX safe?

Low risk

anonymoX allows its VPN master server to open arbitrary URLs in new tabs on every periodic check-in.

Every ~15 minutes, anonymoX contacts master.anonymox.net to retrieve configuration. If the server's response includes a showURL field, the extension unconditionally opens that URL in a new browser tab without user interaction. The extension also fetches ad content from a server-controlled URL and injects it as an overlay into active tabs, with the ad frequency and source URL determined entirely by server response.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.
