Facebook bug exposed up to 6.8M users’ unposted photos to apps
Facebook bug exposed up to 6.8M users’ unposted photos to
apps

Reset the “days since the last Facebook privacy scandal”
counter, as Facebook has just revealed a Photo API bug gave app developers too
much access to the photos of up to 5.6 million users. The bug allowed apps
users had approved to pull their timeline photos to also receive their Facebook
Stories, Marketplace photos, and most worryingly, photos they’d uploaded to
Facebook but never shared. Facebook says the bug ran for 12 days from September
13th to September 25th. Facebook tells TechCrunch it discovered the breach on
September 25th, and informed the European Union’s privacy watchdog the Office
Of The Data Protection Commissioner (IDPC) on November 22nd. The IDPC has begun
a statuatory inquiry into the breach.
Facebook provided merely a glib “We’re sorry this
happened” in terms of an apology. It will provide tools next week for app
developers to check if they were impacted and it will work with them to delete
photos they shouldn’t have. The company plans to notify people it suspects may
have been impacted by the bug via Facebook notification that will direct them
to the Help Center where they’ll see if they used any apps impacted by the bug.
It’s recommending users log into apps to check if they have wrongful photo
access.
Facebook initially didn’t disclose when it discovered the
bug, but in response to TechCrunch’s inquiry, a spokesperson says that it was
discovered and fixed on September 25th. They say it took time for the company
to investigate which apps and people were impacted, and build and translate the
warning notification it will send impacted users. The delay could put Facebook
at risk of GDPR fines for not promptly disclosing the issue within 72 hours
that can go up to 20 million pounds or 4 percent of annual global revenue.
However, Facebook tells me it notified the IDPC that
oversees GDPR on November 22nd, as soon as it established the bug was
considered a reportable breach under GDPR guidelines. It says that it had to
investigate to make that conclusion and let the IDPC know within 72 hours once
it had. The head of communications for the IDPC Graham Doyle tells TechCrunch
“The Irish DPC has received a number of breach notifications from Facebook
since the introduction of the GDPR on May 25, 2018. With reference to these
data breaches, including the breach in question, we have this week commenced a
statutory inquiry examining Facebook’s compliance with the relevant provisions
of the GDPR.”
Facebook tells me the bug did not impact photos privately
shared through Messenger. The bug wouldn’t have exposed photos users never
uploaded to Facebook from their camera roll or computer. But photos users
uploaded but either decided not to post, that got interrupted by connectivity
issues, or that they otherwise never finished sharing could have winded up with
app developers.
The privacy failure will further weaken confidence that
Facebook is a responsible steward for our private data. It follows Facebook’s
massive security breach that allowed hackers to scrape 30 million people’s
information back in September. There was also November’s bug allowing websites
to read users’ Likes, October’s bug that mistakenly deleted people’s Live
videos, and May’s bug that changed people’s status update composer privacy
settings. It increasingly looks like the social network has gotten too big for
the company to secure. Curiously, Facebook discovered the bug on September
25th, the same day as its 30 million user breach. Perhaps it kept a lid on the
situation in hopes of not creating an even bigger scandal.
That it keeps photos you partially uploaded but never
posted in the first place is creepy, but the fact that these could be exposed
to third-party developers is truly unacceptable. And it seems Facebook is so
tired of its failings that it couldn’t put forward even a seemingly heartfelt
apology is telling. This company’s troubles are not only souring users on
Facebook, but employees and the tech industry as large as well. CEO Mark
Zuckerberg told Congress earlier this year that “We have a responsibility to
protect your data, and if we can’t then we don’t deserve to serve you.”
What does Facebook deserve at this point?
