Protecting your Facebook information from hackers

The verbose explanation given by Facebook on its page may not adequately answer all these questions.

"We will be making enquiries with Facebook and our overseas counterparts to establish the scale of the breach and if any United Kingdom citizens have been affected".

It's already known that hackers have made use a loophole in Facebook and stolen 5 Crore access tokens.

It may force the numerous major companies and startups reliant on Facebook's login service to audit their own systems for evidence of malicious activity as a result.

The CEO admitted that "View As" feature in Facebook, which had some malfunction, must have played the spoilsport role.

Access tokens allow people to log into another app using Facebook and are uniquely generated for the specific person and app. Simply put, you can log out or initiate a security audit on your device and account.

What is the security token?

"If you've ever used a Facebook login button on a website, now would be an excellent time for Facebook users to review their App Settings to see which applications and games they've granted access rights to within Facebook".

The social media site has apologised for a data breach affecting up to 50 million account holders worldwide, which was identified over the weekend.

When did this breach occur?

Its hard to find someone who doesn't have a Facebook account.

Under Europe's recently introduced General Data Protection Regulation (GDPR) law, companies that fail to do enough to protect their customers' data face a maximum fine of $23 million, or 4 percent of their global revenue for the prior year, which is where the $1.63 billion figure comes from. In that case, the maker of a personality quiz app on Facebook transferred his database of profile information to a third party, Cambridge Analytica.

Guy Rosen, Facebook's vice president of product management wrote in a blog post: "Since we've only just started our investigation, we have yet to determine whether these accounts were misused or any information accessed".

What is Facebook doing to fix the bug?

Hours after Facebook revealed the breach on Friday, some YouTube videos, which were seen several thousand times, described a method similar to the one used by the hackers to get access to the millions of Facebook accounts, The Telegraph reported on Saturday. Facebook is also taking the precautionary step of resetting access tokens for another 40 million accounts that have been subject to a "View As" look-up in the previous year. The attackers hijacked these access tokens, which helped them log into any of the millions of Facebook accounts.

"Today's disclosure is a reminder about the dangers posed when a small number of companies like Facebook or the credit bureau Equifax are able to accumulate so much personal data about individual Americans without adequate security measures", reads the statement from Warner, who is the vice chairman of the Senate Select Committee on Intelligence and the co-chair of the Senate Cybersecurity Caucus.
