🚨 16 Billion Logins Leaked in Historic Data Breach
Cybersecurity researchers have uncovered one of the largest breaches ever. Over 16 billion login credentials—including social media, corporate, VPN, and email accounts—have been leaked online. The data is recent and weaponizable, gathered through malware from unsecured databases. It includes:
* Usernames, passwords, and URLs
* Apple accounts, Telegram-linked accounts, and more
* Datasets originating from the Russian Federation
Experts warn this leak is a blueprint for mass exploitation, enabling identity theft, phishing, and account takeovers.
