I received one of those messages from a Facebook friend where it says something like "Is this really you in this video?" and then send an accompanying link. I clicked this link from within Messenger on my Android phone and it opened a pornography website in my browser. I immediately closed the site but am now worried what information of mine might be compromised.

I have been googling this and many people say that it is a common phishing scam where they can get my Facebook login details and then send the message on to more people. However, I wasn't taken to a fake Facebook website and was never given an opportunity to provide my login details. I think it was just wanting me to sign up to a pornography website.

* If they didn't get me to login, how would they get my login details? Could I still be compromised?
* And if their intention wasn't to get my details, how did the person that sent it to me get compromised?
* Would it be dangerous if I were logged into the mobile Facebook website in a browser (not the app)?
* Is it possible that something was downloaded to my Android just bey clicking the link? Is there a way I can check (or scan) *effectively*?
