In light of any data security incident, it is generally advisable to remain watchful for any unusual activity related to your personal accounts. Regularly review statements from your financial institutions and credit reports for any unauthorized transactions or new accounts opened in your name.

Consider placing a fraud alert or security freeze on your credit files with the three major credit bureaus (Equifax, Experian, and TransUnion). This can help prevent new accounts from being opened without your authorization. Changing passwords for online accounts, especially those using reused credentials, is also a recommended precaution.
