I always hate to narrow things down, because then I worry that people will start to focus only on those threat actors.
I think everyone in this room is probably already aware that another actor we're concerned about is Russia. We are also concerned about Iran and North Korea. Those are at the top of our list at the moment, but I would say that you should think even more broadly than that and always protect whatever's on your social media account. You never know who's looking and who's trying to gather more information on you.
