An enormous amount of sensitive information including Social Security numbers for millions of people could be in the hands of a hacking group after a data breach and may have been released on an online marketplace, The Los Angeles Times reported this week.
The hacking group USDoD claimed it had allegedly stolen personal records of 2.9 billion people from National Public Data, according to a class-action lawsuit filed in U.S. District Court in Fort Lauderdale, Florida, reported by Bloomberg Law. The breach was believed to have happened in or around April, according to the lawsuit.

What information is included in the data breach?
The class-action law firm Schubert, Jonckheer & Kolbe said in a news release that the stolen file includes 277.1 gigabytes of data, and includes names, address histories, relatives and Social Security numbers dating back at least three decades.
According to a post from a cybersecurity expert on X, formerly Twitter, 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.
Since the information was posted for sale in April, others have released different copies of the data, according to the cybersecurity and technology news site Bleeping Computer.
A hacker known as “Fenice” leaked the most complete version of the data for free on a forum in August, Bleeping Computer reported.
