National Public Data (2024)

National Public Data's 2024 breach exposed 2.9 billion records containing Social Security numbers and addresses, affecting nearly every US citizen. The data was sold on the dark web for $3.5 million, prompting calls for stronger federal regulations. This incident surpasses the 1.1 billion records of the #3 Aadhaar breach, making it the second largest cybersecurity incident by total records, with a scope that threatens identity theft for an entire nation.
