Welcome to the Tech Meme Right Home for Friday, September 28th, 2018. I'm Brian McCullough.

Today, a new Facebook scandal, but this time it's a bit different.

Slack is preparing for an IPO.

There's an exciting new episode of Today in Elon Musk for you,

and of course, the long reads suggestions here's what

you missed today in the world of tech. Early this afternoon Facebook announced it had discovered a security vulnerability affecting

around 50 million Facebook users.

Quoting Guy Raisin, the Facebook VP of product management.

Our investigation is still in its early stages,

but it's clear that attackers exploited a vulnerability in Facebook's code

that impacted view as a feature that lets people see what their own profile looks like to someone else.

This allowed them to steal Facebook access tokens which they could then use to take over people's accounts. Access tokens are the equivalent

of digital keys that keep people logged into Facebook so they don't need to reenter their

password every time they use the app."

So if you were logged out of your Facebook account when you tried to check it this morning

or if you were asked to reset your password, this is why.

As Facebook is still investigating this vulnerability,

it has logged out more than 90 million Facebook users

as a precaution.

Facebook says it does not know the origin or identity of the hackers yet,

nor has it assessed the scope of the attack fully.

Again, Facebook stresses this is early days in its investigation.
