What happened?

The National Public Data breach was a major security incident where unauthorized individuals gained access to a vast database, containing personal information.

According to a post from a cybersecurity expert on X, formerly Twitter, a hacker group that calls themselves USDoD claims to be selling the 2.9 billion records for citizens of the U.S., U.K., and Canada on the dark web for $3.5 million. National Public Data suspects the breach contains critical personal information, including social security numbers.

National Public Data's response

National Public Data has collaborated with law enforcement and governmental investigators to review the potentially affected records. They will provide updates if any significant developments arise that are applicable. National Public Data claims they have strengthened their security measures to help prevent similar breaches in the future and to better protect their systems.
