One of the largest data breaches ever seen has recently hit the public, sharing 16 billion brand-new leaked login credentials. While major data breaches of this scale are typically full of billions of previously leaked credentials, today's megaleak is made of almost entirely previously unreported databases.
Cybernews, the team responsible for IDing and cataloging a significant number of previous major leaks, assembled the datasets making up this most recent 16B leak. Only one dataset in the breach, a 184 million-record batch reported by Wired, had been previously reported. The rest are all new from all over the world, including three distinct batches that held over 1 billion credentials each.
