More than 16 billion login credentials for Google, Facebook, Apple and other platforms have been exposed in one of the largest cybersecurity data breaches of all time, according to a Cybernews report.

The file was completely exposed - no encryption, no password protection, no security - just a plain text document containing millions of sensitive data entries.

Users of several social media platforms are being urged to reset their passwords following findings of a vast data breach in a recent Cybernews investigation.
