What you should do after the September 2018 Facebook Hack

Facebook revealed on September 28, 2018 that attackers managed to exploit a vulnerability on the site that allowed them to take over accounts of Facebook users.

The issue, which affected about 50 million Facebook accounts and potentially 50 million more, used a vulnerability in Facebook’s “View As” feature that allows Facebook users to view their profile pages as another user.

The attackers managed to obtain access tokens which allow anyone to access an account even without supplying a password.

Facebook’s analysis is ongoing at this point in time. The company reacted fast and reset access tokens for affected accounts (nearly 50 million’), and reset access tokens for another 40 million accounts that interacted with View As in the past year.

Investigators have not determined yet whether accounts were misused or if information was accessed. The company plans to update the official security update post on its website once it has more information.

What you may want to do

Facebook users affected by the issue receive a notification about the incident on the next sign-in.

Still, there are some things that you may want to do:

1. Check the last logins

Go to https://www.facebook.com/settings?tab=security§ion=sessions&view and check the devices and locations listed under “where you’re logged in”.

Make sure that you only see devices and locations there that match your activity.

2. Precautions

Facebook supports options to better secure an account.

  • Get Alerts about unrecognized logins — Facebook notifies you when it notices logins from devices or browsers that you have not used in the past. Make sure that this is on.
  • Authorized Logins — Check the list of devices where you won’t have to use a login code. Remove any device or browser on the list that you don’t use anymore or don’t have access to.
  • Two-factor authentication — Adds an extra layer of protection to the account. It was discovered recently, however, that Facebook will use the phone number for advertising purposes (advertisers upload lists of phone numbers, and if your phone number is on that list, you will be served ads from that advertiser).
