Byline Bank's Response

In response to the breach, Byline Bank has taken several steps to mitigate the impact on its customers and to enhance its security measures. The bank is offering credit monitoring and identity protection services at no cost to the affected individuals for 24 months through Experian. These services are designed to help protect against identity theft and to provide peace of mind.

Steps to Take if You Are Affected

If you believe your information was compromised in this breach, it is crucial to act promptly to protect your identity. Here are some recommended actions:

1. Enroll in the offered credit monitoring service by visiting Experian IdentityWorks and using the provided activation code.
2. Regularly review your account statements and credit reports for any unauthorized activity. You can obtain a free credit report from each of the three major credit bureaus once every 12 months at AnnualCreditReport.com or by calling 1-877-322-8228.
3. Consider placing a fraud alert or a security freeze on your credit files. A fraud alert informs creditors of possible fraudulent activity within your file and requests that the creditor contacts you before opening new accounts. A security freeze will prevent creditors from accessing your credit report entirely, which helps prevent new accounts from being opened in your name.
4. Stay vigilant and report any suspicious activity to the relevant authorities. If you suspect identity theft, you should also contact the Federal Trade Commission at FTC Identity Theft or by calling 1-877-ID-THEFT (438-4338).
