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.

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

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.
