Hi!
As mentioned in the lecture download the hstshijack caplet archive from resources, uncompress it and replace the whole hstshijack directory inside the caplets directory, then try it again.

Basically, if the page gets downgraded to http then the password will be captured, if you don’t see it it’s just because bettercap was not able to filter it, or the credentials are buried between all of the other data that bettercap displays on screen.
Look carefully through all of the results you got, if you’re sure it’s not there then just use Wireshark as shown in lectures 46 – 49 to find the username and password.

LinkedIn is not in the HSTS hijack list because LinkedIn is not preloaded in Chrome or Firefox, what means by its not preloaded is that it is not in the HSTS list that is stored at the local target computer, therefore you should be able to downgrade it just like any other https website.
In edge however LinkeIn is pre-loaded so you’ll have to add it to the list as shown in the course.

Greetings!
