Facebook was recently hacked as the company says it recently discovered a security breach affecting nearly 50 million user accounts.
The hack is the latest setback for Facebook during a year of tumult for the global social media service. The security flaw could have allowed 50 million accounts to be taken over by hackers.
In a blog post, the company says hackers exploited a bug that affected its “View As” feature, which lets people see what their profiles look like to someone else. That would let attackers steal the “access tokens” Facebook uses to keep people logged in. Possession of those tokens would allow attackers to “seize control” of user accounts, Facebook said.
“It’s clear that attackers exploited a vulnerability in Facebook’s code,” vice president of product management Guy Rosen said in a blog post. “We’ve fixed the vulnerability and informed law enforcement.”
To deal with the issue, Facebook reset some logins, so 90 million people have been logged out and will have to log in again. That includes anyone who has been subject to a “View As” lookup in the past year.
Facebook says it doesn’t know who is behind the attacks or where they’re based. In a call with reporters on Friday, CEO Mark Zuckerberg said that the company doesn’t know yet if any of the accounts that were hacked were misused.
The Taiwanese hacker has vowed to hack and delete Mark Zuckerberg’s Facebook page.
The hacker also said he’ll broadcast the takedown live on Facebook on Sunday… that is really daring.
However, Taiwanese hacker named Chang Chi-yuan has claimed he would take down Mark Zuckerberg’s Facebook page in a live broadcast before appearing to pull out of the plan.
Chang Chi-yuan told his 27,000 followers he would target the Facebook founder’s own account this Sunday. Then he backtracked today and said he would instead demand money from Facebook in return for flagging up the glitch to Facebook. He added that he had not expected the world’s media to pick up on his plans. He said;
“Broadcasting the deletion of Facebook founder Zuck’s account. Scheduled to go live”.
Some commenters had criticised his plans, with one saying:
“Listen man, if you really have a bug that can take over Zuck’s page, I don’t recommended you do it.
You can just inform them about that bug and you will get rewarded for this.”
Later Chang wrote in a comment: “I am canceling my live feed. I have reported the bug to Facebook and I will show proof when i get bounty from Facebook.”
The Taiwanese social media celebrity has previously claimed to have targeted the software of major corporations including Apple and Elon Musk’s Tesla.
