National Public Data (NPD), a data broker, has confirmed a massive data breach that reportedly affected over 272 million individuals and potentially impacted 2.9 billion people globally. The breach, which dates back to December last year, involved the theft of sensitive personal information, including Social Security numbers, names, and addresses. The breach has led to a class action lawsuit alleging that the Social Security numbers of every American were compromised. The breach was exacerbated by the publication of NPD's admin credentials and passwords in plain text, raising significant cybersecurity concerns. Two cybersecurity firms have launched websites to help individuals determine if their information was exposed. The breach has sparked widespread concern as it potentially impacts billions of people globally, including those in the US, UK, and Canada.
