Hi! The message tries to frighten targets by claiming to have access to their messages, social media accounts, and messengers. The email message claims to know the password to your email address and demands that you pay a lot of money. Do not do that! It is basically a phishing scam conducted by self-proclaimed hackers attempting to blackmail you through a series of email messages. As you can see, the email can appear legitimate to many people. But, the same message has been sent around the internet to many people.
