Massive X Data Breach Exposes Information on 200 Million Users

Cybersecurity experts verify leaked dataset containing metadata and email addresses, while X remains silent on the incident.

A dataset of 201 million X user records, including metadata and email addresses, was leaked by a hacker named ThinkingOne and verified by SafetyDetectives.
The breach is linked to a larger dataset of 2.8 billion records leaked earlier in January 2025, potentially stemming from a 2022 vulnerability in X's systems.
The leaked information does not include passwords but raises concerns about phishing and social engineering risks for affected users.
ThinkingOne claims to have contacted X about the breach but received no response, and X has yet to acknowledge or address the incident publicly.
The breach underscores ongoing security challenges for X, now owned by Elon Musk's xAI, and highlights broader concerns about data protection on social media platforms.
