World’s Biggest Data Breach?: Personal Information of 2.9 Billion Exposed

In one of the largest data breaches ever reported, the personal information of approximately 2.9 billion individuals has been exposed. This breach, revealed through a recent class action lawsuit, involves a substantial amount of sensitive data including full names, addresses, Social Security Numbers (SSNs), and more. The breach is linked to National Public Data, a firm specializing in background checks and fraud prevention. The cybercriminal group responsible, known as USDoD, allegedly stole this data and attempted to sell it on the dark web for $3.5 million. In this article, we analyze the data breach, answer if it is indeed the world’s biggest, tell you what to do if you think you could be affected, and share ways to protect your data from such breaches.

World’s Biggest Data Breach?: Personal Information of 2.9 Billion Exposed in National Public Data Hack—How It Happened

National Public Data amassed this vast trove of personal information through a process known as “scraping.” Scraping involves collecting data from websites and other sources online, often without the explicit consent of the individuals whose data is being gathered. In this case, National Public Data scraped non-public sources for personally identifiable information (PII) of billions of people, many of whom did not willingly provide their data.

The breach was uncovered through a class action lawsuit filed in the US District Court for the Southern District of Florida. One of the plaintiffs, notified by an identity theft protection service, discovered their data had been exposed and leaked on the dark web. The lawsuit seeks not only to have National Public Data securely dispose of the compromised data but also to secure compensation for the victims and implement stricter security measures. We tried accessing the National Public Data website but it seems it is inaccessible.

Could This Be the World’s Biggest Data Breach?

The sheer scale of the data breach involving National Public Data, which exposed the personal information of 2.9 billion individuals, makes it one of the largest breaches ever recorded. While the exact number of those affected is still being confirmed, the breach rivals previous record-setting incidents, such as the 2013 Yahoo! breach that compromised the data of 3 billion users.

If further investigations reveal that all 2.9 billion individuals’ data was indeed compromised, this breach could potentially take the title of the world’s largest. The global reach of the breach, encompassing data from multiple countries, adds to its significance and the widespread potential damage it can cause.

The Threat of Stolen Social Security Numbers in Massive Breach that Exposed PII of 2.9 Billion People

Among the most concerning aspects of this breach is the exposure of Social Security Numbers (SSNs). SSNs are a critical piece of personal identification in the United States, used for everything from tax filings to credit applications. When hackers gain access to SSNs, they can perpetrate a range of fraudulent activities, including opening new credit accounts, filing fake tax returns, and even stealing benefits. The damage from such activities can be long-lasting, as victims may not realize their SSN has been misused until they experience financial difficulties or are contacted by debt collectors for accounts they never opened.

The Potential Damage and Consequences

The misuse of stolen SSNs can lead to devastating consequences for victims. Identity theft can ruin an individual’s credit score, making it difficult to obtain loans, mortgages, or even rent a home. In some cases, it can take years to fully recover from the financial and emotional toll of having one’s identity stolen. Additionally, victims may face legal challenges, such as proving they were not responsible for fraudulent activities carried out in their name.

The Financial Impact of Stolen Data

Stolen data is incredibly valuable on the dark web, with hackers making millions from selling personal information. SSNs, credit card numbers, and medical records can be sold or used to commit fraud, take out loans, or even blackmail victims.

The financial and emotional toll on individuals can be devastating, with victims often facing years of legal battles and financial recovery.

How to Protect Your Data

In light of these breaches, protecting personal information has become more critical than ever. Here are steps Americans can take to safeguard their data:

1. Freezing Credit: One of the most effective ways to protect against identity theft is by freezing your credit. This prevents anyone from accessing your credit report without your permission, making it harder for criminals to open accounts in your name. Major credit bureaus like Equifax, Experian, and TransUnion offer free credit freezing services.
2. Monitoring Financial Accounts: Regularly check your bank and credit card statements for any unauthorized transactions. Set up alerts for any unusual activity and consider using credit monitoring services that notify you of any changes to your credit report.
3. Strengthening Digital Security:
   • Use Strong Passwords: Ensure that your online accounts are protected by strong, unique passwords. Consider using a password manager to generate and store complex passwords.
   • Enable Multi-Factor Authentication (MFA): MFA adds an extra layer of security by requiring a second form of verification in addition to your password. This can include a code sent to your phone or a fingerprint scan.
   • Be Wary of Phishing Scams: Be cautious of unsolicited emails, texts, or calls asking for personal information. Always verify the source before clicking on links or providing details. Test yourself—Don’t Click here .
4. Checking if You’ve Been Affected: Websites like Have I Been Pwned allow you to check if your email address or phone number has been involved in a data breach. If your information is found, take immediate steps to secure your accounts.
5. Choosing Companies with Strong Cybersecurity: Before sharing your personal information, research the company’s cybersecurity practices. Look for companies that use encryption, regularly update their security protocols, and have transparent privacy policies. Verify if the company has had previous breaches and how they handled them.

What to Do If Your Data Has Been Misused after Exposure in a Data Breach

If your credit card or personal information has been used fraudulently, take the following steps immediately:

1. Report the Fraud: Contact your bank or credit card company to report the unauthorized transaction. They can freeze your account to prevent further misuse and investigate the fraud.
2. File a Police Report: If your identity has been stolen, file a report with your local police. This can help in disputing fraudulent charges and may be required by credit bureaus or banks.
3. Place a Fraud Alert: A fraud alert on your credit report notifies potential creditors to verify your identity before issuing new credit. This can be done through any of the major credit bureaus.
4. Close Affected Accounts: If an account has been compromised, close it immediately and open a new one. Update any automatic payments linked to the old account.
5. Consider Identity Theft Protection Services: These services monitor your personal information online and alert you to any suspicious activity. They can also assist in recovering from identity theft by providing legal and financial support.

Ensuring Better Digital Security

By staying vigilant and taking proactive steps to protect your personal information, you can mitigate the impact of data breaches and enhance your overall digital security. Here are a few approaches:

1. Choose Companies with Robust Cybersecurity: When selecting service providers, consider their cybersecurity practices. Look for companies that offer transparency about their security measures and have a track record of protecting customer data.
2. Verify Security Practices: Research and verify the security practices of companies you interact with. This includes checking for regular security audits, encryption standards, and response plans for data breaches.
3. Regularly Update Software: Ensure that your operating system, applications, and antivirus software are up to date with the latest security patches.

How Stolen Data Is Used by Hackers

Hackers can exploit stolen data in various ways to make substantial profits:

1. Identity Theft: Using stolen personal information, hackers can open fraudulent accounts, take out loans, or commit other forms of identity theft.
2. Phishing Scams: Stolen data can be used to craft highly targeted phishing scams, increasing the likelihood of successful attacks.
3. Blackmail and Extortion: Hackers may use sensitive information to blackmail or extort individuals or organizations.
