Turn On MFA | CISA (2024)

Turn On MFA | CISA (1)

Deandre learned many of his friends were having problems with online scammers hacking into their social media accounts or receiving phishing messages through email. He thought it was strange but didn’tworry too much about it. Deandre felt like he was probably safe. He didn’thave that many followers. Who’dwant to hack him?

But one day, all of that would change. Deandre started his morning off as usual, grabbed a cup of coffee and went to sign into his email. Except, he wasn’t able to log in; his email account had been taken over. He then received text messages from family members asking if he was really the one posting weird messages on social media.

Hackers were posing as him online and posting to his social pages. He checked it out and was embarrassed by the fake posts. Deandre soon discovered somebody had hacked into more accounts and changed the passwords. This included his bank account and retail apps. Hackers made unauthorized purchases and transactions.

Deandre was shocked that in just a quick amount of time, he had lost control of all his important data and finances. He later discovered that since his accounts were linked, hackers gaining access to one entry point, his email, allowed access to other accounts. Deandre wished he had practiced more caution and used MFA on his email account. That could have stopped them from hacking his email, and he could have avoided the whole chain of events. He had to work long hours to recover what was possible and create a new email account.

Deandre now always uses MFA and is reassured that his account is significantly more secure—he’llbe the only one controlling it in the future.
