Data breaches can happen at any time to any company, even large-scale enterprises, which means our information is always at a high risk of being compromised. If compromised, what do you do after a data breach? Are there steps you can take to protect your data after it’s stolen? The answer is yes, and we’ve compiled some helpful tips to follow in the aftermath of a data breach.

5 Important Steps to Take After a Data Breach

If your information has been compromised, it's up to you to protect your accounts and data following the breach. Although the company that was hacked may offer identity theft services free of charge, you still need to do your due diligence to ensure your identity (and money) isn't stolen.

1. Determine What Information Was Exposed

Before you take any steps after a data breach, it’s essential to know what was leaked in the breach. Often, companies will reach out after a breach to let you know whether your information was compromised or not. This isn’t always a guarantee, though.

Several tools are available for you to check whether your email address or phone number has been compromised. These include:

2. Contact Your Financial Institution or Credit Card Issuer

If any of your financial information was exposed in the breach, it’s important to contact your financial intuition, such as your bank or credit card issuer. They can help you determine the best next steps based on your situation. For instance, you may need to change your account numbers, dispute or cancel any authorized charges, or set up fraud alerts. 

3. Place a Fraud Alert and Freeze Your Credit

If the recent breach exposed your social security number or financial information, it might be ideal to freeze your credit files. This will ensure identity thieves can’t open any new accounts in your name. You’ll want to contact the three major credit bureaus and place a fraud alert and freeze your credit:  

If you’re applying for a credit card, buying a new car or home, or renting an apartment, you’ll have to remember to lift the freeze temporarily. You can also request a free annual credit report to make sure someone isn't taking out lines of credit under your name. Regularly monitoring your credit reports can help you spot unauthorized accounts in your name.

4. Remove Your Home Address from Websites

Did your home address get compromised? If so, you’ll want to act quickly or risk your home address being posted on other sites. You can search for your address on search engines. If it shows up, we suggest you report it immediately to Google and Bing.

You can also file a report with Twitter, Facebook, and Reddit if your private information was shared. Information on the internet is difficult to remove completely, but you can also use paid services to remove your address from specific websites. These services include Kanary and DeleteMe.

5. Change and Strengthen Any Compromised Passwords

When your password has been compromised, it’s crucial to change and strengthen that password, not just for this account but any other accounts with the same password.

As humans, we can be creatures of habit. So, it’s likely you’ve used the breached password more than once, and hackers can use that information to steal your data on other accounts. We suggest using a password manager, which will help you generate and store complex passwords for all your accounts.

What is a Data Breach?

A data breach is an intentional or accidental exploitation of a corporation’s database to reveal confidential or protected information. This information can include your:

  • Social Security number
  • Bank account details
  • Credit card numbers
  • Personal health information
  • Passwords
  • Email addresses

Often, cybercriminals find an unauthorized entry point to hack into a corporate computer or network to expose consumer data and use it for identity theft or fraud. However, in some instances, an employee of the corporation may accidentally expose your information. Either way, your data gets compromised, and cybercriminals can profit at your expense.

According to multinational cybersecurity and anti-virus provider Kaspersky, data breaches can occur due to several reasons, such as:

  • An accidental insider
  • A malicious insider
  • A malicious outsider
  • A lost or stolen device with sensitive information that’s unencrypted

Why Should You Care About Data Breaches?

Businesses, governments, hospitals, individuals, and retailers alike can be the subject of a data breach and have their personally identifiable information exposed. Cybercriminals have mastered the art of revealing information through the internet, Bluetooth, text messages, social media, or other online services you use.

The subsequent damage of data breaches can be substantial. They can:

  • Ruin an organization’s reputation
  • Expose military operations and other types of confidential information to foreign parties
  • Put individuals at risk of identity theft

For these reasons, you must investigate whether your data has been exposed and take proper precautions if it has. 

How to Stay Informed About Data Breaches

If you want to stay informed about data breaches, there are three main things you should do:

  • Follow us for the latest updates on data breaches and other online scams.
  • Keep your email current for any of your online accounts because companies will usually send out communication regarding data breaches.
  • Use websites such as Have I Been Pwned, Firefox Monitor, F-Secure Identity Theft Checker, and BreachAlarm, to check if your information has been compromised.
