How can I tell if my email account has been hacked?

Episode 1172 (30:06)

Elizabeth from Venicia, CA

Elizabeth got an email from her friend that included suspicious links, and she's wondering if his email account was spoofed. She looked in the header, but didn't see anything. How can she find out if it was spoofed? Leo says the tale is the CCs. They would only be able to put so many addresses in a field, and if they are using multiple fields, then she'll know the person has cracked the account. Yahoo has always had security issues. So the account has been hacked and there's all kinds of ways to do it. First thing to do is change the password, and make it a difficult one. Leo also recommends using Two Factor authentication whenever possible as well.
