533 Million Facebook Users’ Data Leaked: What You Need to Know

In April 2021, it was reported that data from over 533 million Facebook users had been leaked online. The leaked data included personal information such as phone numbers, email addresses, birthdates, and Facebook IDs. This is a significant breach of privacy for millions of Facebook users around the world, and it has raised concerns about the security of personal data on social media platforms.

How the Data Leak Happened

According to reports, the data was leaked from a vulnerability that was first discovered in 2019. The vulnerability allowed hackers to scrape data from Facebook’s servers by exploiting a flaw in the “Add Friend” feature. Facebook had reportedly patched the vulnerability, but the data had already been stolen and was being sold on the dark web.

What You Can Do to Protect Your Data

If you are one of the 533 million Facebook users affected by the data leak, there are several steps you can take to protect your data. First, you can check if your data was included in the leak by using online tools that allow you to search for your email address or phone number in the leaked data. If your data was included in the leak, you should change your Facebook password and enable two-factor authentication to secure your account.


You should also be cautious of phishing emails or messages that may attempt to trick you into providing personal information or login credentials. Hackers may use the leaked data to create convincing phishing messages, so it’s important to be vigilant and only provide personal information to trusted sources.

Finally, you should review your privacy settings on Facebook and other social media platforms to ensure that you are sharing personal information only with trusted friends and contacts. It’s also a good idea to limit the amount of personal information you share online, as this can help reduce the risk of identity theft or other forms of cybercrime.


The recent data leak of 533 million Facebook users’ data is a reminder of the importance of protecting personal information online. While Facebook has taken steps to address the vulnerability that led to the leak, the incident highlights the need for individuals to be vigilant about protecting their own data. By taking steps to secure your Facebook account, being cautious of phishing messages, and limiting the amount of personal information you share online, you can help protect your data and reduce the risk of identity theft or other forms of cybercrime.
