8 things identity thieves do with your information

What do identity thieves do with your information? More than most people imagine. From opening financial accounts to pretending to be you at the doctor’s office, the ways cybercriminals exploit stolen data are broad, harmful, and costly.

A person reading about how identity thieves could use their information.

Someone in the U.S. falls victim to identity theft every five seconds. This post explains what identity thieves do once they get your information—and more importantly, how you can help stop them before they do serious damage.

1. Open financial accounts

Once cybercriminals have access to key personal data—like your name, address, Social Security number, and date of birth—they can impersonate you to open new credit cards, bank accounts, or loans. With some smooth social engineering, they might even talk their way into bypassing security questions with your bank.

These fraudulent accounts can go unnoticed for months, potentially damaging your credit and finances.

Tip: Check your credit report regularly for unfamiliar accounts and use a credit monitoring service that alerts you to new activity.

2. Make unauthorized purchase

If thieves get your credit or debit card details, they can quickly rack up charges—often on big-ticket items like electronics, designer goods, or prepaid gift cards. These transactions might seem small at first, but they add up fast.

Tip: Dispute any charges you don’t recognize immediately with your bank and set up real-time alerts for your financial accounts.

3. Take over existing accounts

With a combination of leaked passwords, security questions, and email access, cybercriminals can hijack your bank, email, or social media accounts. Once inside, they may drain funds, change account details, or use your platform to scam others.

Tip: Enable two-factor authentication (2FA) on all sensitive accounts and use a password manager to create and store strong, unique passwords.

4. Sell it

One of the most common things identity thieves do with your information is sell it—often in bulk—on the dark web. The dark web is a hidden corner of the internet where stolen data is bought and sold like currency.

Tip: Use a dark web monitoring tool to scan for your personal information and change compromised passwords immediately.

5. Use your health insurance

Medical identity theft occurs when someone uses your information to receive medical care or fill prescriptions under your name. This can result in false entries in your medical records and surprise bills.

Tip: Shred old medical statements and insurance documents and review your Explanation of Benefits (EOB) statements for unfamiliar services.

6. Apply for federal or state benefits

Fraudsters can use your identity to apply for unemployment, Social Security, or other government benefits. These scams often divert your benefits into their own accounts, leaving you empty-handed when you actually need help.

Tip: Contact your state’s unemployment office if you suspect fraud and set up online accounts for government benefits yourself to claim them securely.

7. Carry out phishing attacks

Armed with your name and email address, scammers can launch phishing attacks on your contacts— pretending to be you to trick your friends or family into handing over information or money.

Tip: Warn your contacts if you see duplicate or suspicious accounts using your name and keep your social profiles private and secure.

8. Submit your taxes

Tax identity theft happens when someone files a fraudulent return in your name to claim your refund. By the time you go to file your taxes, the IRS may already think it’s been done.

Tip: File your taxes as early as possible and use strong security practices for your online tax accounts.

How can you keep your information in your hands?

You can reduce your risk of identity theft by adopting a few simple but powerful habits. Start by avoiding calls from unknown numbers and never sharing personal information unless it’s absolutely necessary. Make sure to enable two-factor authentication (2FA) whenever possible, and always keep your software and devices updated. It’s also wise to shred any sensitive documents before you dispose of them. Finally, consider locking or freezing your Social Security number with the appropriate agencies to keep others from using it if it falls into the wrong hands.
