267 Million Facebook Users Data Breach:

As reported by the Britain-based tech research firm Comparitech and security researcher - "Bob Diachenko", 
The leaks may contain user Facebook User IDs, phone numbers, and names of mostly US-based users.
Diachenko, who examined the evidence, the data likely came from 

“an illegal scraping operation or Facebook API abuse by criminals in Vietnam.”

Data Exposed Exposed on the Web

After discovering that personal details of 267 million Facebook users were exposed online, Diachenko notified the Internet service provider managing the IP address of the server so that access could be removed.
However, the data was also posted to a hacker forum as a download, said the security researcher.
Facebook IDs are unique, public numbers associated with specific accounts, which can be used to discern an account’s username and other profile info.
While how criminals obtained the user IDs and phone numbers are not entirely clear, one possibility is that the data was stolen from Facebook’s developer API before the company restricted access to phone numbers in 2018.
Facebook’s API is used by app developers to add social context to their applications by accessing users’ profiles, friends list, groups, photos and event data. Phone numbers were available to third-party developers prior to 2018.
also examined that, The 267 million Facebook Breach user's data could eventually be used for mass phishing campaigns due to its inclusion of phone numbers, so users would be well advised to be suspicious of any text messages or emails asking for your password or other sensitive information. Comparitech also suggests changing all the fields in Facebook's privacy settings to "Only friends" or "Only me" and disabling the ability of search engines to link to your profile in order to prevent your data from being scraped by bots.
