What to Do After You Experience Data Theft

Data theft can lead to a major business disruption which then results in a significant revenue loss. It can also lead to several other issues for an individual. For this reason, you must implement the necessary precautionary measures to ensure that your system and accounts are protected from data theft. However, if your data is already stolen, make sure that you perform the steps below to mitigate its adverse effects.

Identify what data was stolen

One of the first things that you need to do after you experience data theft is to identify which of your data has been stolen. For instance, check whether the stolen data includes social security numbers, credit card information, mailing addresses, phone numbers, or even passwords and security questions. Those behind the data breach can easily use these data to assume the identity of another person to commit other criminal acts.

Change your passwords and other authentication credentials

As soon as you verified that a data breach happened to your account, make sure to change your passwords and login credentials immediately. In case you are using the same password for other accounts that were not affected by the issue, it is a good idea to change them too. Following this, make sure to leverage a two-factor authentication to make it more difficult for the hackers to access your account.

Get in touch with the right people

In case the data stolen from you includes sensitive information that can be used against you, then make sure that you get in touch with the right people. The legal experts behind Cain Law Office suggest that you immediately get in touch with a defense attorney should you be a victim of identity theft or fraud wherein crimes were committed by a person posing as you. Conversely, get in touch with financial agencies and consider a credit freeze for your account because this will make it difficult for hackers and thieves to open a new account using your name.

Strengthen your security measures

To ensure that your risk of experiencing data theft is significantly reduced, make sure to strengthen your security measures. This entails the need for you to come up with stronger passwords or investing in a firewall, as well as an antivirus protection software. It is also necessary for you to update your applications and software accordingly because these minimize their vulnerabilities, particularly when patches are implemented. It is also a good idea to perform regular data backups while monitoring your account and operations diligently.


In conclusion, no individual, company, or business would want to experience data theft because this can negatively impact their daily lives and their operations. If you already do, keep calm for you to accurately identify which of your data has been stolen. Immediately change your passwords and other authentication credentials too. Contact the right people for the next steps that you have to take, but the key is in strengthening the security measures that you are implementing to ensure that this scenario will never happen again.
