Over 16 billion passwords leaked in 'largest' data breach in history
Monday 23 June 2025 - 19:14

More than 16 billion passwords have been leaked online in what researchers are calling the largest amount of breached data in history.

This massive exposure, highlighted by the “Cybernews” platform, is raising growing concerns about the security of digital accounts for millions of users worldwide.

Unlike previous leaks that often recirculated old data, this new collection comprises over 30 different databases.

Crucially, some of these contain new and previously unpublished information. The compromised data includes passwords, usernames, and email addresses linked to widely used platforms such as Gmail, Facebook, Apple, Telegram, and GitHub.

The majority of this sensitive data was reportedly gathered using malicious software known as “Infostealers.” These tools are designed to directly steal information from victims’ web browsers and devices. Infostealers are often installed when users click on fake files or phishing links. Once active, they can access saved passwords, login tokens (cookies), and even active user sessions, granting hackers significant access to accounts.

Cybersecurity experts are urging all users to take immediate preventive measures. They recommend checking trusted websites to see if your data has been compromised and changing affected passwords immediately.

Additionally, users should activate two-factor authentication (2FA), use strong and unique passwords for all accounts, and exercise caution by avoiding suspicious links or downloading dubious files.
