Emails about "account has been hacked"
This is a sextortion scam email. It is designed to frighten you into sending Bitcoin by claiming the sender hacked your device, recorded you watching adult content, and will expose your private information unless you pay.
This email is a well-known type of scam, and the claims in it are almost certainly fabricated. The message itself does not prove that your device has been hacked or that anyone has recorded you.
DocuSign spam: "Document Ready for Your Review"
Emails which require you to login and sign with your password look like this. But you did not expect any document, why you would do this? The Hook: Scammers pose as government agencies (IRS, FBI), businesses (Amazon, tech support), or family members.
