How to secure your LinkedIn account with AlterEgo shielded emails

Back in May 2016 there was no escaping the news about the Linked-In data breach. 167 Million accounts have been compromised and were sold and resold for a mere $2.2k. That’s a fabulously low amount, which boils down to a market value of $0.001 cents per entry.

Ask yourself this: is your online identity worth more than a thousandth of a cent?

Could it also be that the same password you used on Linked-In tries to also protect you on other sites? How about your email address? By now 1.4 billion email addresses have been compromised.

To check out breaches that include your info, head out to https://haveibeenpwned.com and run a search. If you’ve never done this before, you’ll definitely in for a surprise!

Good, scared ya? This is a reactive approach, but in hindsight better late than never. Let’s work together to secure your Linked-In account using an ALTER EGO shielded email.

  • Go to your profile’s Privacy and Settings section and click Manage.
  • Once the email address box is up, just let ALTER EGO work its magic.
  • Click on the ALTER EGO button in your browser’s toolbar.
  • Since you probably don’t have an ALTER EGO for Linked-In yet, let’s have a new one created. The entire identity that’s on display here will be new, different and uniquely created for you!
  • We are planning to use just the shielded email address for now, whatever that is. The more complicated and hard to remember, the better. So let’s just go ahead and hit Autofill.
  • In order for Linked-In to ensure that it’s you doing these actions, and not a hacker half-way around the world, a confirmation is needed via a different communication channel. Sending an email verification takes care of this.
  • Security is all about layers. Just like peeling an onion, an attacker would need to go through several hoops to compromise your Linked-In account. This password verification step is needed to mitigate at least session hijack attacks. We don’t need to worry about this. Just know that Linked-In have recently stepped up their security game and are taking more precautions. All for the best.
  • We can now go ahead and fill in the password or let the password manager to it automatically.
  • The new ALTER EGO shielded email address is now added to your account, but it’s not verified yet.
  • We’re now going to use your original email account to confirm that the new ALTER EGO shielded email was added by you and not a bad guy. Just click the link in the confirmation email.
  • This will drive us back to Linked-In and we can see the new email address confirmation on the front page.
  • To tie up all the loose ends, we need to make sure that attackers have no side way of knowing your real email address and linking you with your data on other compromised sites. Back to Privacy & Settings and let’s change again the Email addresses. The quick link for this is: https://www.linkedin.com/psettings/email
  • We plan to make your unique ALTER EGO shield email is the primary email as far as Linked-In is concerned. As you’ve probably learned the drill, it’s very nice on Linked-In’s behalf to ask us for the password, just to make sure that hackers have more hoops to go through before causing havoc.
  • With the shielded email as primary, we are no longer offering the malicious actors any extra info, like our initial email address. We can safely go ahead and remove it. All the email that you receive from Linked-In will still reach you via just like before, only that the path is now highly secure.
  • Last password confirmation and we’re done.
  • This is how the Email address section ought to look like for a secured account.

Over the course of this endeavour we’ve learned a bit about the way attackers value our information, their value of our private data and the way Linked-In accounts can be secured for future breaches. Some good further steps include also changing your Linked-In password and keep doing this for other accounts that you own on different sites.
