A newly disclosed trove of stolen credentials has underscored the scale of modern cybercrime after U.S. federal investigators uncovered hundreds of millions of compromised passwords on devices seized from a single suspected hacker. The dataset, comprising approximately 630 million passwords, has now been integrated into the widely used Have I Been Pwned (HIBP) database, significantly expanding its ability to warn users about exposed credentials.
The passwords were provided to HIBP by the Federal Bureau of Investigation as part of ongoing cybercrime investigations. According to Troy Hunt, the security researcher behind the service, this latest contribution is particularly striking because it originates from one individual rather than a large breach aggregation. While the FBI has shared compromised credentials with HIBP for several years, the sheer volume associated with this case highlights how centralized and extensive credential theft operations have become.
Initial analysis suggests the data was collected from a mixture of underground sources, including dark web marketplaces, messaging platforms such as Telegram, and large-scale infostealer malware campaigns. Not all of the passwords were previously unknown, but a meaningful portion had never appeared in public breach repositories. Roughly 7.4% of the dataset represents newly identified compromised passwords, amounting to tens of millions of credentials that were previously undetectable by users relying on breach-monitoring tools.
