I use Little Snitch to monitor my network connections. It is reporting that Adobe has a connection from unsigned software to a server with no reverse name located in California from a process called "node" with out a code signature and just an IP address this could be anything. I suspect it is OK but the problem is this is a security vulnerability in the Adobe software that a third party could attack to redirect a user to a malicious server.
So first question: Adobe is this connection OK and actually an Adobe server?
Second question: Will you fix this... at least sign the code per the Apple standards?
