Don’t make yourself a target through your LinkedIn profile. If you work in a high-risk field, like cryptocurrency, we highly recommend against broadcasting that information to the Internet (e.g., don’t say where you work, don’t call yourself a crypto evangelist and don’t say you attend monthly crypto meetups)

Locking Down Your Account

Navigate to your account information to view your LinkedIn Security & Privacy settings:

  1. Click the Me icon at the top of your LinkedIn homepage.
  2. Select Settings & Privacy from the dropdown.
  3. Click the Sign in & Security tab at the top of the page. 

     Account Access

    • Email Addresses - Any email you have here must have a strong password, 2FA (Google Auth or YubiKey, no SMS) and disabled SMS recovery capabilities.  
    • Phone numbers - Remove any associated phone numbers. If a phone number is already used for 2FA you can change your 2FA settings to use an Authenticator App instead. Do not add a phone number for “Use for password reset”.
    • Change Password - Make sure this password is long, complex, and unique. If you haven’t change this in a while, change it now.
    • Where you’re signed in - Review this and remove any session other than the one you are on. You will be asked to login again your other devices. This will clear any rogue session that may exist.

     Site Preferences

    • Language - Choose your favorite language.

    • Showing Profile Photos - You can leave this on for “Everyone”.
    • Feed preferences - You can leave this alone unless you want to customize who you follow and see updates from.
    • Name, Location, Industry - Pay attention here. This is where a lot of the privacy information comes from within LinkedIn.

      • Your headline leaks where you currently work. Consider changing this to “YOUR_ROLE at Undisclosed” if you work somewhere that might put you at a higher risk.
      • Current position maps to what your current position is in your profile. Leave this as-is for now and we will customize it later.
      • Uncheck “Show education in my intro”.
      • Country/Region - You can leave this as-is or change to something fake.
      • Zip Code - Remove this if there is anything there.
      • Industry - Select something other than Financial Services, Banking, etc.
      • Contact Info - click the “pencil” icon and clear out anything sensitive. Your email there is the email that you login with and we’ll secure that later in this exercise. Click Apply when done. Scroll back down to “Summary”
      • Summary - This is your Bio. Consider against leaking sensitive info that might make you a target.

     How others see your profile and network information

    • Review Settings under Edit Your Profile. The most important piece here is to restrict the visibility of your profile. The less publicly visible, the better. Configure the settings for the following fields:
      • Your Profiles Public Visibility - This is recommended to be turned “Off”.
      • If you don’t want to go that far or can’t for business reasons make the following changes to the radio buttons below:
        • Profile Photos - Set to your connections only.
        • Headline - Show (Consider against mentioning sensitive info) 
        • Websites - Hide
        • Summary - Show (Consider against mentioning sensitive info)
        • Posts & Activities - Hide
        • Current Experience - Hide (Consider against mentioning sensitive info)
        • Past Experience - Hide
        • Education - Hide
        • Volunteer Experiences - Hide
        • Projects - Hide
        • Publications - Hide
        • Courses - Hide

    • Set “Only You” for the option of Who Can See Your Connections. If a hacker is trying to target you, they’ll do that either directly or through one of your connections. Similarly, if a hacker is trying to target someone else or a company, they’ll do that either directly or through a connection, which could be you. Minimizing who can see your connections will make this step of the attack harder.
    • Viewers of this profile also viewed - Change this to “No” this might tip someone off of others who work with you at your workplace even if their profile is sanitized.
    • Minimize Who Can See Your Last Name settings to be abbreviated to just the first letter of your last name.
