Facebook said its
engineers discovered a security weakness this week that could let
attackers hijack people’s accounts. The vulnerability, which the company
said had been fixed, affected nearly 50 million accounts.
Facebook said
in a web post that the security issue was related to the “View As”
feature, which allows people to see a preview of what their profile
looks like to other people, like specific friends. Hackers exploited a
weakness in the tool to gain access to digital keys that let people access Facebook from a personal device without having to re-enter a password. The keys could then be used to take over people’s accounts, the company said.
The social networking giant said that it had reset all the access keys
for affected users and that those users would have to log back into
their accounts. In other words, there is not much you have to do. But
there are some precautions you should take to protect yourself from the
attack.
Do a Device Audit
The
best way to determine whether someone has gained improper access to
your account is to do an audit of the devices that you have used to log
into Facebook. On Facebook’s Security and Login page,
under the tab labeled “Where You’re Logged in,” you can see a list of
devices that are signed into your account, as well as their locations.
If you see an unfamiliar gadget or a device signed in at an odd
location, you can click the “Remove” button to boot the device out of
your account.
Change Your Password
Facebook
says that because it has fixed the vulnerability, there is no need to
change your account password. But to be extra safe, you probably should
anyway — especially if you use a weak password or saw any suspicious
devices logged into your accounts.
If
you decide to change your password, choose a complex one — and do not
reuse a password you have used on a different site. Try creating long
and complex passwords consisting of nonsensical phrases or one-sentence
summaries of strange life events and add numbers and special characters,
like: My favorite number is Green4782#.
To keep your passwords organized and easy to access, consider using a password-management app
like 1Password or LastPass. These tools let you keep all your passwords
in a digital vault that can be opened with one master password, and
they can also automatically generate complex passwords.
Turn on Two-Factor Authentication
Like many sites, Facebook offers a security feature called two-factor authentication.
It involves text messaging a unique code to your phone that you must
type in after entering your password. This way, even if someone gained
access to your password, it would be difficult to log in without that
code. Even though Facebook fixed this week’s security vulnerability,
every user should have this feature turned on.
