- falcolas 10y agoSo long as you have a DNS resolver which respects TTLs, you could be behind anything - they're dynamically changing DNS to point at your localhost. It's not the remote server making the connections, it's your web browser. At which point, it can be exfiltrated, thanks for the DNS tricks which get around CORS.
- Randgalt 10y agoThat doesn't make sense. A web browser is just a TCP connection after all. If the port isn't open on the server there's no way to connect to it.
