Facebook says the leak of the data of 533 million users was not caused by hackers, but by a scrape.
The 3rd. In April, it was revealed that the data of 533 million Facebook users had been leaked, including profile names, phone numbers, email addresses and FB IDs. Facebook had initially stated that the security vulnerability was discovered in August 2019 and the vulnerability was fixed. The social media giant did not disclose this information at the time and only confirmed it on Tuesday.
Facebook announced that the data was obtained by the attackers by scraping their contact import tool until September 2019. The tool is designed to help people connect with others on the platform through their contact list.
The company claims that no financial or medical information or passwords were exposed by the security breach.
We believe that the data in question was plucked from people’s Facebook profiles by malicious people using our contact importer before September 2019. Through the steps we’ve taken, we’re confident that the specific issue that allowed them to scrape this data in 2019 no longer exists, said Mike Clark, Facebook’s director of product management.
But since there have been numerous data breaches at Facebook between 2018 and 2019, it’s hard to determine exactly when and how the attackers gained access to this information unless you take Facebook at its word, which conveniently decided to speak out after remaining silent on the issue since 2019.
In September 2018, 50 million Facebook profiles were hacked, followed by another data breach of 120 million users, including private messages, in November 2018. The following month, the bug exposed the photos of 6.8 million users who were accessing third-party apps. In April 2019, Upguard discovered that approximately 146 GB of data containing 540 million user records had been lost due to third-party app-records. It could be any of the above, or even the third-party data sharing scandal at Cambridge Analytica.
When we learned how malicious agents were using this feature in 2019, we made changes to the contact importer. In this case, we updated it to prevent malicious users from using programs that mimic our application and downloaded a large set of phone numbers to see which ones are suitable for Facebook users. The previous feature allowed them to query a set of user profiles and obtain a limited amount of information about those users that was contained in their public profiles.
Speaking at the 2019 F8 developer conference, Zuckerberg said: The future is private, but his statement is really hard to believe given the company’s current policy of transparency and apathy when it comes to user data security.
