Most of 2.2 billion Facebook users had their data scraped by externals – because it was easy to do

At this point, the social media company is just going for broke, telling the public it should just assume that “most” of the 2.2 billion Facebook users have probably had their public data scraped by “malicious actors.”


Meanwhile, reports have focused on a variety of issues that have popped up in just the last 24 hours. It’s hard to focus on what matters—and frankly, all of it seems to matter, so in turn, it ends up feeling like none of it does. This is the Trump PR playbook, and Facebook is running it perfectly. It’s the media version of too big to fail, call it too big to matter. Let us suggest that you just zero in on one detail from yesterday’s blog post about new restrictions on data access on the platform.

Mike Schroepfer, Facebook’s chief technology officer, explained that prior to yesterday, “people could enter another person’s phone number or email address into Facebook search to help find them.” This function would help you cut through all the John Smiths and locate the page of your John Smith. He gave the example of Bangladesh where the tool was used for 7 percent of all searches. Thing is, it was also useful to data-scrapers. Schroepfer wrote:

However, malicious actors have also abused these features to scrape public profile information by submitting phone numbers or email addresses they already have through search and account recovery. Given the scale and sophistication of the activity we’ve seen, we believe most people on Facebook could have had their public profile scraped in this way. So we have now disabled this feature. We’re also making changes to account recovery to reduce the risk of scraping as well.

The full meaning of that paragraph might not be readily apparent, but imagine you’re a hacker who bought a huge database of phone numbers on the dark web. Those numbers might have some use on their own, but they become way more useful for breaking into individual systems or committing fraud if you can attach more data to them. Facebook is saying that this kind of malicious actor would regularly take one of those numbers and use the platform to hunt down all publicly available data on its owner. This process, of course, could be automated and reap huge rewards with little effort. Suddenly, the hacker might have a user’s number, photos, marriage status, email address, birthday, location, pet names, and more—an excellent toolkit to do some damage.

In yesterday’s Q&A, Zuckerberg explained that Facebook did have some basic protections to prevent the sort of automation that makes this particularly convenient, but “we did see a number of folks who cycled through many thousands of IPs, hundreds of thousands of IP addresses to evade the rate-limiting system, and that wasn’t a problem we really had a solution to.” The ultimate solution was to shut the features down. As far as the impact goes, “I think the thing people should assume, given this is a feature that’s been available for a while—and a lot of people use it in the right way—but we’ve also seen some scraping, I would assume if you had that setting turned on, that someone at some point has accessed your public information in this way,” Zuckerberg said. Did you have that setting turned on? Ever? Given that Facebook says “most” accounts were affected, it’s safe to assume you did.


Mark Zuckerberg has known from the beginning that his creation was bad for privacy and security. Activists, the press, and tech experts have been saying it for years, but we the public either didn’t understand, didn’t care, or chose to ignore the warnings. That’s not totally the public’s fault. We’re only now seeing a big red example of what it means for one company, controlled by one man, to have control over seemingly limitless personal information. Even the NSA can’t keep its secret hacking tools on lockdown, why would Facebook be able to protect your information? In many respects, it was just giving it away.
