National Public Data Confirms Hackers Stole Social Security Numbers

National Public Data says that about 1.3 million people were affected by the breach, although a lawsuit alleges 2.9 billion records were compromised.

The company named in a class-action lawsuit last week that claims that billions of Americans’ records including Social Security numbers were stolen in a data breach confirmed that it was hacked.

In a notice published by the Maine attorney general’s office on Aug. 17, National Public Data said that 1.3 million people, including more than 2,000 Maine residents, were affected by the data breach. The lawsuit, filed earlier this month, alleged that the personal information, including Social Security numbers, of hundreds of millions of Americans were hacked and leaked online.
