Zuckerberg Finally Talks Cambridge Analytica, Promises Audit

Facebook chief Marking Zuckerberg on Wed finally weighed in on the Cambridge Analytica scandal in a post that pledged to investigate all apps that had access to large amounts of user data before Facebook changed its rules in 2022, and farther restrict electric current developers' access to data.

"I started Facebook, and at the end of the day I'g responsible for what happens on our platform," Zuckerberg wrote on his personal Facebook page.

The CEO has been nether pressure to speak upwardly almost the data-sharing debacle, which has at present been in the news since Friday night, when a Facebook VP addressed information technology in a blog post. "I've been working to sympathize exactly what happened and how to brand sure this doesn't happen once more," Zuckerberg wrote today.

COO Sheryl Sandberg shared Zuckerberg's mail on her own page and reiterated that she "spent the past few days working to get a fuller moving-picture show and so we can end this from happening over again."

"We know that this was a major violation of peoples' trust, and I deeply regret that we didn't do plenty to deal with information technology," Sandberg said.

The bulk of Zuckerberg's post outlines what we already know: in 2022, Dr. Aleksandr Kogan developed a personality test app that gathered data, with permission, from 270,000 Facebook users. That information should have remained with Kogan, who said he needed information technology for academic research. Merely he instead gave it Strategic Communication Laboratories (SCL)/Cambridge Analytica and SCL'due south Christopher Wylie. They used information technology to build profiles on potential voters for GOP candidates like Ted Cruz and Donald Trump.

The operation was not express to 270,000 people, though. Kogan'southward app also provided access to friends of friends, ultimately supplying Cambridge with 50 1000000 raw profiles, according to the New York Times.

Facebook found out nigh this in 2022 and order Cambridge to delete the data, which it said it did. But the Times, The Guardian, and the UK'southward Channel 4 reported recently that it had not, prompting Facebook to ban Cambridge, Kogan, and Wylie from its platform completely last calendar week.

Submit to an Inspect or Become Banned

Facebook no longer allows for the type of information collection Kogan engaged in five years agone; rule changes put in place in 2022 effectively banned the collection of data from friends of friends without permission.

But what about pre-2014? Zuckerberg said today that Facebook "will investigate all apps that had admission to large amounts of information before we changed our platform...and nosotros will conduct a full audit of any app with suspicious activity."

Those who decline an audit or are found to accept misused information will be banned. Facebook pledged to notify users whose data was misused; "That includes people whose data Kogan misused here too," Zuckerberg said.

All developers, meanwhile, will take access to less data going frontward. "We will reduce the data you give an app when you sign in— to but your name, profile photo, and email address," Zuckerberg said. "Nosotros'll require developers to not only get approval but also sign a contract in order to ask anyone for access to their posts or other private data. And we'll take more changes to share in the adjacent few days."

Meanwhile, if yous don't utilise an app for three months, Facebook volition remove programmer access to it.

Facebook also promised to put its privacy controls forepart and center on the News Feed in the next month.
