Cybersecurity researchers have discovered one of the largest data leaks in history. A total of 16 billion login records were found in over 30 exposed datasets, each containing millions to billions of entries. This massive data leak affects nearly every type of online service imaginable.
These datasets include logins from:
Social media platforms like Facebook and Instagram
Corporate services like Microsoft 365 and Slack
Developer portals like GitHub
Messaging apps like Telegram
Government-related services
Each record typically contains a URL, username, and password—a format consistent with data stolen by infostealer malware.
Researchers found that the datasets were briefly exposed through unsecured Elasticsearch or cloud storage buckets. These were not old, recycled breaches. Many were recent, and structured for
It is unclear who owns the data. Some believe security researchers compiled it for monitoring. However, many signs point to cybercriminals, who value large datasets to launch:
Phishing attacks
Ransomware intrusions
Business Email Compromise (BEC)
Credential stuffing campaigns
There is no proof of a centralized breach at companies like Facebook, Google, or Apple. However, credentials found in the leak include login pages for those services. So, even if the companies themselves weren’t hacked, users of those platforms are still at risk.
This is more than just a data leak. It’s a blueprint for cybercrime at scale. A success rate of under 1% can still lead to millions of compromised accounts. That’s why basic cyber hygiene is more important than ever.
Protect your data with these steps:-
Use a password manager to generate and store strong passwords.
Enable multi-factor authentication (MFA) on all accounts.
Regularly update passwords, especially on critical accounts.
Scan your devices for malware, especially info-stealers.
Monitor for suspicious activity using breach notification tools.
