Commonwealth Business Bank Data Breach Lawsuit Investigation
Did you receive a letter from Commonwealth Business Bank about a cyber-attack? Sensitive financial and personal details may already be in criminal hands. Explore your legal options and learn how to safeguard your identity now.
What Happened?
On February 6, 2025, Commonwealth Business Bank (often branded as CBB Bank) uncovered suspicious activity inside its computer network. A forensics investigation later confirmed that an unauthorized actor accessed internal systems over a two-week window—January 25 to February 8, 2025.
During that time, files containing customer data were viewed or copied. The incident was formally disclosed to the California Attorney General and notification letters were mailed beginning August 13, 2025.
What Information Was Exposed?
The investigation indicates that the following categories could have been compromised:
- Full names
- Social Security numbers
- Dates of birth
- Mailing addresses & contact details
- Government-issued ID numbers
- Bank account numbers and other financial data
- Potentially limited medical information
Because both personal identifiers and account details were involved, experts consider this a high-severity breach that can lead to identity theft, tax fraud, and unauthorized banking activity.
Your Immediate Action Plan
Commonwealth Business Bank is offering 24-month Experian IdentityWorks credit monitoring. While valuable, monitoring alone does not stop misuse. Combine it with the steps below:
- Enroll in the free credit-monitoring service as soon as possible.
- Check all bank and credit-card statements weekly for unfamiliar charges.
- Place a fraud alert or credit freeze with any one of the three major credit bureaus.
- Watch for phishing attempts—never click suspicious links or share codes sent by text or email.
- Document out-of-pocket losses (extra banking fees, hours spent, postage, phone costs).
Can You File a Data Breach Lawsuit Against Commonwealth Business Bank?
Data-breach litigation seeks to hold organizations accountable when inadequate security leads to compromise. Victims may be able to claim damages for:
- Reimbursement of fraud-related expenses and overdraft fees

- Future identity-protection services
- Emotional distress and loss of privacy
If you received a notification letter—or believe you should have—you may qualify to participate in a class-action or individual claim. Statutes of limitation apply, so acting quickly preserves your rights.

FAQ: Commonwealth Business Bank Data Breach
How do I know if I was affected by the Commonwealth Business Bank data breach?
The bank is sending physical letters to everyone whose information appeared in the compromised files. If your mailing address has changed recently, contact customer service to verify.
What is the deadline to join a Commonwealth Business Bank data breach lawsuit?
Deadlines differ by state and the type of legal action. To avoid losing your right to compensation, consult with a data-privacy attorney as soon as you receive your notice.
Does the free Experian IdentityWorks service protect me completely?
No. Credit monitoring alerts you after suspicious activity is detected, but it cannot stop fraud in real time. You should still set up MFA and monitor accounts yourself.
Will filing a claim cost me anything up front?
Most data-breach cases are handled on a contingency-fee basis. That means attorneys are paid only if a settlement or court award is secured on your behalf.
What compensation could I receive from a Commonwealth Business Bank lawsuit?
Potential recovery may include reimbursement for fraud losses, credit-monitoring costs, the value of lost time, and damages for emotional distress or privacy invasion.
