Earlier this year, hackers stole nearly three billion records from the National Public Data (NPD) and posted the stolen details on the dark web for everyone to see in August 2024. The stolen info includes full name, date of birth, addresses, cell numbers, and social security numbers (SSN). Multiple media outlets have claimed that the database likely contains the social security number of almost every American. It appears that hundreds of millions of American citizens have been affected by the breach. 

Tool created to check for compromised data

A small company from Florida has created a tool called Pentester that allows people to check if their details are among the stolen records. The tool prompts people to input their first name, last name, state, and year of birth. Then performs a check rapidly by going through the billions of records.

The tool is free of charge, and users can perform unlimited checks.

Data quality issues

The tool works, but it also shows that the leaked data is, luckily, far from perfect. Often, users report wrong numbers attached to their names. Others say that even though they are American citizens, details appear not to be compromised and are luckily not included in the leak.

Internet users took to social media to also report that SSNs of deceased individuals are included in the list, and the info appears to be out of date. For example, SSN matches but includes old addresses and phone numbers. There are a lot of duplicates, too. 

Dangers of the data breach

This is not the first time SSNs have been stolen in mass. In 2017, Chinese hackers penetrated Equifax’s systems. They stole millions of social security numbers from one of the three major credit bureaus.

What makes the NPD data breach notably worse than the Equifax breach is that the stolen social security numbers from the leak in 2017 never really resurfaced on the dark web. Still, the NPD records appear to be up for grabs for anyone interested and capable of accessing the dark web. Which could mean a lot of trouble to anyone who does not take measures to prevent bad actors from utilizing the leaked details.

Protecting yourself

It is crucial for everyone involved in the data breach to consider freezing their credit with all major bureaus. Equifax, Experian, and TransUnion.

A credit freeze would prevent bad actors from opening a fraudulent line of credit and performing other malicious types of identity theft. Having top-notch antivirus software on all connected devices is also a must.
