I am studying how privacy leakage happens by Chrome extensions.
First, "privacy leakage" I mean, for example, the extension sends host users browsing history/behaviors to 3rd party.
Second, I found the permissions are defined in "manifest.json" of extension source code.
My question is:
What kinds of permissions are usually used by extensions to intentionally cause privacy leakage?
I guess some permissions like "webRequest", "storage" may be relevant, right?
What means "webRequestBlocking"? I checked but still not sure. Please use an example to explain. Just for example, "Flatbook" extension uses webRequestBlocking.
