Cybernews also claims that the 16 billion number is possibly inflated due to leaks coming from multiple data sets, which means there could be many duplicate records.

More than 16 billion passwords have been leaked online in what researchers are calling the largest amount of breached data in history. This massive exposure, highlighted by the “Cybernews” platform, is raising growing concerns about the security of digital accounts for millions of users worldwide.

The leaked login credentials spanned 30 databases, many of which contained recent, structured data harvested by infostealer malware. "This is not just a leak – it's a blueprint for mass exploitation," said Cybernews researchers.
