How to protect yourself from cyber hackers?

Don't overshare

  • Don’t have a social media account
  • Make it private if you have to have a social media account
  • Be careful what you post on social media especially while on vacation

Find a hard to guess password

  • Log in with two-factor identification, which requires additional personal information or a second device
  • Use nothing easily guessed or pick a phrase instead
  • Don’t save passwords “in plain text” on phones
  • Use a password manager

Watch what you download

  • Watch if apps are accessing your phone number, location, contacts, or address book
  • Check to see what every app is collecting, even popular gaming apps can leak personal information
  • Don’t let your banking app automatically save logins or pin numbers

Know your ID is already out there

  • You can go online and delete information about yourself or hire someone to do it
  • Most banks have fraud detection and sometimes will buy fraudulent client cards or intercept fraud attacks
