Facebook Hacked, 50 Million Users Affected
Facebook “discovered a security issue” that the company said allowed attackers to “take over people’s accounts.”
Facebook disclosed that hackers stole data from 50 million people on Friday.
In a blog post, Facebook’s vice president of product management Guy Rosen said that the company’s engineering team “discovered a security issue affecting almost 50 million accounts.”
“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,” Rosen wrote. “This allowed them to steal Facebook access tokens which they could then use to take over people’s accounts.”
Rosen wrote that the vulnerability exploited by the hackers is fixed and Facebook is working with law enforcement. Facebook has a total of roughly 2 billion users, so the breach impacted approximately 2.5 percent of Facebook users.
“We patched the issue last night and are taking precautionary measures for those who might have been affected,” Facebook CEO Mark Zuckerberg said in a call with reporters.
The company is also resetting the access tokens of another 40 million people.
“As a result, around 90 million people will now have to log back in to Facebook, or any of their apps that use Facebook Login,” Rosen wrote.
The company is still investigating the incident. Rosen wrote that it doesn’t know who’s behind it nor where they are from. If you were one of the around 50 million victims, or the other 40 million users potentially affected, you should’ve been forced to log in again.
