What to do after a data breach

Living in a highly connected digital world has its risks. Having your personal information caught up in a data breach is a big one.

The biggest data breaches of the 21st century have exposed billions of records and criminals are using that information for credit card fraud, identity theft, account takeovers, and so much more.

You can’t prevent every data breach, but you can make yourself a much harder target and minimize the damage when breaches happen.

5 steps to take after a data breach

Step 1: Find out if you've been breached

Check if your data is already out there:

  • Go to haveibeenpwned.com and enter your email address or phone number (it’s legit and run by a respected security researcher).
  • Sign up for alerts so you know immediately when your email appears in new breaches.
  • Use MySudo Reclaim to discover data breaches involving your Gmail account.

If you’ve been in a breach (and you probably have), at least now you know.

Step 2: Check your free credit reports

Credit reports allow you to check if someone has tried to apply for credit in your name, like taking out a car loan or signing up for a buy now, pay later service. Follow the FTC’s advice.

Step 3: Freeze your credit

This is the single most effective thing you can do to prevent identity theft, and it’s free.

A credit freeze locks your credit report so nobody (including you) can open new credit accounts until you unfreeze it.

How to do it:

  • If in the US, contact all three credit bureaus: Equifax, Experian, and TransUnion.
  • Request a credit freeze (it’s free by law).
  • Save your PIN/password because you’ll need it to temporarily unfreeze when you want to apply for credit.

This matter because even if someone has your social security number, they can’t open credit cards or loans in your name if your credit is frozen.

Step 4: Monitor your accounts

  • Set up alters to get text or email alerts for every transaction on your bank accounts and credit cards.
  • Review your credit report regularly (you get one free report per year from each bureau at annualcreditreport.com) and see step 2 above.
  • Check your medical insurance statements for services you didn’t receive

Act fast if you see something wrong:

  • Report unauthorized charges immediately.
  • Dispute fraudulent accounts.
  • File a police report if needed.

Step 5: Be skeptical of everything

After a breach, scammers may use your stolen data for years. Stay alert to red flags:

  • Emails claiming to be from your bank asking you to “verify” information.
  • Phone calls saying there’s a problem with your account (hang up and call the company directly).
  • Texts with links asking you to update payment info.
  • Anyone asking for your social security number, passwords, or account details.

Remember: Legitimate companies will never ask for sensitive information via email or text.
