Is sslspeedy safe?

Low risk

sslspeedy runs JavaScript from 678in.com in its popup and routes non-.cn traffic through a proxy that server picks.

The extension fetches a server list and proxy login response from 678in.com as script and runs it in the popup, which holds proxy privileges. The returned server value is placed into a PAC script that sends all non-.cn browser traffic through that host. The user's account credentials are sent to 678in.com in the request.

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