Helium Summary: The largest ever password leak, named RockYou2024, was uploaded by a hacker known as 'ObamaCare' on July 4, 2024. The dataset contains approximately 9.9 billion unique passwords, amalgamated from various data breaches over the past 20 years.

Researchers at Cybernews discovered the file on a popular hacking forum.

This leak significantly increases the risk of credential stuffing attacks, as many of these passwords have been used for multiple accounts.

Security experts urge users to employ strong, unique passwords and enable two-factor authentication (2FA) to mitigate risks [techrepublic.com][computing.co.uk][readwrite.com].
