The owner of the Invest Answers' channel (James) has published three “emergency videos” stating that his Twitter account has been hacked. Apparently he uses a Yubikey to protect it but somehow the account was hacked (someone theorised with a stolen authentication cookie).
The hackers have posted a link to jup.ag but concealed with a short link and have disabled posts on that post (which James never does). The link is probably malicious.
Do not click on that link.
