Facebook CEO Mr. Mark Zuckerberg

Social networking giant Facebook Inc is no stranger to data breaches. Earlier this year, records of at least 500 million users were found on Amazon, and in September, phone records of 219 million users were exposed on an easily accessible online server. Now, a report from Comparitech and security researcher Bob Diachenko states that 267 million Facebook accounts, user names and telephone numbers have been found sitting on an Elasticsearch server. The data is believed to be scraped off of the service by entities operating in Vietnam. Take a look below for more details.
