Is FlashVPN - 安全,快速,便捷的代理! safe?

Low risk

FlashVPN routes browser traffic through vendor proxy servers and supplies proxy credentials to any HTTP auth challenge.

FlashVPN sets a Chrome proxy so web traffic goes through servers supplied by the vendor's app, and it stores the login email and token passed from flashvpn.io. Its background script answers every HTTP authentication prompt on all sites with the stored VPN proxy username and password, without checking the prompt comes from the proxy.

Shared hosts - 4 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
