[Solved] How can i steal a specific cookie’s value?

Question

There is no generic means to steal cookie data. It requires either:

a security vulnerability (typically an XSS one) in a site that you can exploit to read the data or
for the connection to be insecure and for you to have access to the networks the requests and response pass through

The Synchronizer Token approach to blocking CSRF attacks (which is what you are trying to bypass) would be useless if stealing cookies was commonly possible.
