Quadrant Capital Data Breach Lawsuit Investigation
Were you notified that Quadrant Capital lost control of your personal information? Over 1,200 clients may now face identity-theft risks after an employee email account was hacked. Find out if you can claim compensation and protect your data today.
What Happened?
Quadrant Capital, a Center Valley, Pennsylvania–based registered investment adviser, discovered unusual activity in an employee’s email account on July 21, 2025. An internal forensic investigation later confirmed that an unauthorized third party gained access to that account and may have viewed files containing sensitive client data.
After containing the incident, the firm reviewed the compromised mailbox to identify affected individuals and types of information exposed. Notification letters began mailing on September 5, 2025 to all known victims, including at least 1,200 people nationwide.
What Information Was Exposed?
The data at risk differs by person but can include any of the following:
- Full name
- Social Security number
- Mailing address
- Financial account details
Why This Breach Matters
Unlike a credit-card number, Social Security numbers and addresses cannot easily be replaced. Cyber-criminals use them to open fraudulent accounts, apply for loans, or commit tax refund fraud. Given Quadrant Capital’s focus on high-net-worth clients, the stolen data carries elevated black-market value.
Your Legal Options
Data-privacy laws require organizations to safeguard client information and promptly notify victims. When they fail, victims may be entitled to:
- Reimbursement for out-of-pocket expenses related to fraud or credit monitoring
- Compensation for time spent mitigating identity theft
- Statutory damages under certain state consumer-protection statutes
