Cybercriminals will often create fake profiles on social media sites like Facebook and Linkedin, with the objective of gathering sensitive information about you. By looking at your social media page, they can use your personal information to develop a phishing scam. To do this, they might create an alias or impersonate somebody you know before sending the friend request. If you don’t know the person, simply reject their request. If it looks like someone you know, but you’re still not sure, reach out to that person externally to confirm it’s really them.
