Facebook mobile clients don't use the Internet?

The web is not the same as the Internet, though. The web is an open platform built on open protocols on top of the Internet.

Interesting question: What is the Web? HTTP, or HTTP+HTML? Facebook mobile clients use HTTP, so are they using the web?

The torrent to end all torrents.

Would it even be possible to exfiltrate all that data? It's hard to imagine even storing all that they're generating in a single day. What's the most an attacker could likely get? Usernames & passwords for all users? Complete profile/album/comment data on a few tens of millions?

An attacker could attempt to damage or destroy some or all data. Covertly or openly. Immediately or over a long run.

And how many robots?

Less than 2% according to Facebook's last 10-Q:

"We also seek to identify "false" accounts, which we divide into two categories: (1) user-misclassified accounts, where users have created personal profiles for a business, organization, or non-human entity such as a pet (such entities are permitted on Facebook using a Page rather than a personal profile under our terms of service); and (2) undesirable accounts, which represent user profiles that we determine are intended to be used for purposes that violate our terms of service, such as spamming. In 2014, for example, we estimate user-misclassified and undesirable accounts may have represented less than 2% of our worldwide MAUs."

When the Facebook hack comes, it will be devastating.

Getting in might be possible, but then the attacker would have to covertly exfiltrate and store all of Facebook's content to do a dump. Does J. Random Attacker have enough storage to do this?

Maybe; realistically, the Internet speed would probably be more of a limiting factor. At mine, it would take almost a week to fill up 1 terabyte of storage. That's plenty of time to go get a few more HDDs. At 1 Gbps you'd have about 2 hours.

They keep a lot of data in cold storage as well, so not sure how easy it would be able to get everything. Probably just whatever data they think will be likely accessed soon and is in relatively ephemeral storage.

Mmmmm silent corruption without underlying verification of the data. The most evil of attacks.

used Facebook in a single day Just to clarify, is that fb.com, messenger, whatsapp, comment widgets etc combined?

I highly doubt they think that way when qualifying numbers for PR purposes. Regardless of how they connected to Facebook it is still Facebook Inc and it is still hell of a number.

If they are counting people who were only served a "like" button on other site's pages, this announcement boils down to "the internet is a big place! Full story at 11."

> What's the most an attacker could likely get?

Remember that thing when a guy from Europe asked from Facebook to give him everything they knew about him (which European citizens are allowed to request by law) and got over 1000 pages of information from Facebook?

Now, multiply that by a billion (well, two or three billions actually).
