This is my first question here in stackoverflow, so pardon me if I am missing something!
I'm working on a project related to VPN security. They main goal of the project is to detect if a VPN client is introducing some sort of malware ( spyware included ) in my activity. They may do so in orther to get some proffit out of their VPN, for not many people offer good things for free!
I know Javascript Injection for tracking porposes is a thing. What I want to know is the following:
Is there any way to find if Javascript has been injected by analyzing network traffic? Let's say I don't trust that my VPN is not tracking me by Javascript injection. Could I know by analyzing the traffic on a router?
Thanks in advance, hope I have made myself clear!
