A cybersecurity firm recently found that Facebook has an unsecured database that was full of hundreds of millions of users’ data and that this data has been accessed by unauthorized sources and is now on the dark web.

If you’re unfamiliar with the term “dark web” it’s basically like it sounds. Imagine it being the dark alleyway in a gang and drug-infested city. It’s the internet version of that where all the hackers and criminals hang out.

Experts warned that people identified in the database could be targeted by spam messages or phishing schemes in the future so be aware of that. Maybe that’s why people are getting phone calls now from their own phone numbers.

According to Daily Mail,

The Facebook IDs, phone numbers and full names of 267,140,436 users, most residing in the US, were discovered in the database by cybersecurity firm Comparitech and researcher Bob Diachenko, according to a report published Thursday.

The report warned that people identified in the database could be targeted by spam messages or phishing schemes.

Although it is not yet clear how the sensitive information was exposed, Diachenko traced the database back to Vietnam and speculated that it may have been compiled through an illegal process called ‘scraping’ – where automated bots copy public information from Facebook profiles – or stolen directly from Facebook’s developer API.

Since the discovery of the security flaw, access to the database has been removed, but it comes a day late and a dollar short because the damage has already been done and your information is now likely in the hands of a number of hackers since a link to download all of the user information was posted on a hacker forum.

If you’ll recall, just a few months ago Facebook was at the front of a scandal in which 400 million user phone numbers were exposed as well as last year’s scandal of Cambridge Analytica in which millions of user’s data was collected without their consent for political purposes.
