The breach contains data from Apple, Facebook, Google, Telegram, GitHub, and even government services.
Researchers at Cybernews have discovered what could be the second-largest data breach in history, exposing more than 16 billion username and password combinations.
The data, found across 30 unprotected databases, includes records from past leaks and newly compromised credentials obtained via infostealer malware and credential stuffing attacks.
“This is not just a leak – it’s a blueprint for mass exploitation,” Cybernews warned, adding that the breach contains data from Apple, Facebook, Google, Telegram, GitHub, and even government services.
While some records were linked to a recent 184 million-entry exposure, the majority were previously unknown. The largest individual database held 3.5 billion credentials.
The breach could enable identity theft, phishing, and unauthorized account access on a global scale.
Experts recommend users immediately update passwords, enable two-factor authentication (2FA), and use antivirus software to block malware.
Cybernews emphasized the urgency: “Even a small success percentage could give hackers access to millions of accounts.”
