PTC Web Desk: In what cybersecurity experts are calling a historic and highly alarming incident, over 16 billion user credentials have surfaced online, marking one of the biggest password leaks in internet history. The data dump, uncovered by Cybernews and reported by Forbes, is believed to be a fresh and highly organised collection of login credentials stolen through infostealer malware, posing serious threats to individuals, corporations, and governments around the world.

What’s in the leaked database?

This unprecedented breach contains usernames and passwords for a broad spectrum of platforms and services, including: Major email providers Social media sites like Facebook, Google, and Telegram; developer tools such as GitHub and some government and institutional portals.

The data is meticulously structured, often showing direct website URLs followed by login details, making it extremely easy for cybercriminals to exploit.

Why this breach is particularly dangerous

What sets this leak apart is its scale and accessibility. Security researchers confirm that this is not an outdated compilation of past breaches; rather, it’s a massive trove of newly stolen credentials. Experts estimate the leak to include around 30 separate datasets, collectively amounting to over 16 billion login details.

Worryingly, this sensitive data is now available for sale on dark web forums at affordable rates, making it accessible to even low-skilled cybercriminals. This greatly increases the risk of phishing scams, identity theft, and large-scale account takeovers across the globe.

In light of this breach,Google has urged users to move away from traditional passwords and adopt passkeys—a more secure, phishing-resistant method of authentication.

The FBI has issued renewed warnings to avoid clicking on suspicious links sent via email or SMS, especially those requesting login information.
