How to protect yourself after a data breach

22 May 2020

I posted about the EasyJet data breach yesterday, but realised I didn’t provide comprehensive advice regarding what actions to take to safeguard your online identity if you’ve been involved in the breach.

There are a few threats you can be exposed to following a data breach like EasyJet’s. I outline some of these below along with the protective measures you can take.

Leaked login details

If your email and password for an account were leaked, cybercriminals will attempt to use this combination on other online services.


Social engineering

When personal information (like your full name, email, phone number, location, identification numbers, etc) is leaked online, it becomes easier for someone to figure out details about you which grant them access to your accounts.

This is why “security questions” are no longer a secure way of protecting your account if you forget your password. Most modern and big companies don’t support this method anymore. After all, how hard is it to guess your mother’s maiden name or your city of birth?



Your email address is usually leaked along with your personal information. This means you’ll probably receive very convincing emails (with your personal information, which is now available publicly) from people pretending to be your bank, Facebook, and so on. They’ll try to get you to give them even more personal information like passwords and card details.
