Is Onlinesim Access safe?

Low risk

Onlinesim Access fetches proxy settings over plaintext HTTP and applies them to OnlineSim domains.

When its OnlineSim health check fails, the extension requests proxy configuration from scrapi.on-mail.ru over unencrypted HTTP. It trusts the returned proxy host, port, protocol, and optional credentials, then installs a browser proxy rule for OnlineSim domains.

Where it sends data

Destinations our analysis observed Onlinesim Access contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • scrapi.on-mail.ru

    Onlinesim Access sends data to scrapi.on-mail.ru. No other extension we have analysed sends data here.
