A group of hackers has done it filtered 2.7 billion records of Americans' personal information, including Social Security numbers and physical addresses, online.

The hacking group, which identified itself as USDoD, claimed responsibility for the data theft in April, targeting National Public Data (NPD), a platform that provides personal information for background checks on employers , private investigators and staffing agencies.
According to a class-action lawsuit filed in Fort Lauderdale, Florida, the group managed to breach NDP's security and made off with a large amount of personal records.
USDoD initially tried to sell the entire database, which included data from the US, UK and Canada, for $3.5 million.
However, various entities have since leaked bits of that data, and the most recent release contains particularly sensitive information, Engadget and Bleeping Computer report.
Previous leaks associated with this breach included phone numbers and email addresses, but this latest release reportedly does not include those details.
Instead, the focus is on the most critical personal data, leading to serious concerns about identity theft and fraud.
