Hacker Leaks data of 1.2 billion Facebook users are your data on the dark web? Knows how to …

In another greatest violation of the privacy in Meta's history, over 1.2 billion Facebook user records were reported by a hacker under the alias, the bytebreaker. The hacker offered this data for sale on the dark web. Cybernews, a cybersecurity -outlet, has reported that the hacker, bytebreaker, which has published examples of around 100,000 user data sets and confidential information, contained users -ids, full names, e -mail addresses, telephone numbers, birth data, gender and location. This was leaked through a well -known dark web forum.

How did the hacker trigger the data?

The hacker claimed that they had used one of the APIs from Facebook and were able to access the confidential information without authorizations. This sensitive information can now lead to a number of thefts, fraud, phishing and other cybercrime. The cybercriminals take advantage of the API tools and receive safety precautions to access the basic profile information. API tools enable apps to interact with various platforms. The APIs of other platforms were also targeted, including Openai, Shopify and Godaddy.

Metas clarification

The parent company of Facebook, which belongs to Mark Zuckerberg, has not yet confirmed or denied the data leak. The META spokesman has made it clear that this is not new, and from 2021. In 2021, data from over 500 million users were leaked through and Meta has been proven by EUR 265 million by European data protection authorities.

Many experts have also clarified that there are some overlaps with 2021 Break data and current 100.00 record samples. However, after the number has increased, critics argue that Meta had not taken any measures to solve these weaknesses in 2025. Meta has repeatedly suspended lawsuits and punishments regarding these security violations.
