The Indiana Attorney General's office lists a data breach report from Chatham Asset Management LLC, filed January 15, 2026. Companies in this situation send legally required notification letters to affected individuals — if you found Chatham Asset Management LLC's letter in your mail, this page explains what it means and what you can do.
The Indiana Attorney General filing confirms the breach notice — not a court case. Settlement amounts, claim deadlines, and opt-in/opt-out instructions appear here only when a public court record supports them. No outcome is estimated or guaranteed.
Chatham Asset Management LLC's filing with the Indiana Attorney General lists these compromised data types:
The more sensitive the data involved, the stronger the potential claim. Disclosure of these categories is legally recognized harm.
Chatham Asset Management LLC operates as a private investment firm and financial institution, managing capital and portfolios for institutional investors, high-net-worth individuals, and various private funds. Because of its core operations in wealth management and asset allocation, the firm routinely collects, processes, and stores vast quantities of highly sensitive personal and financial data. This information is critical for executing trades, maintaining regulatory compliance, performing anti-money laundering checks, and servicing client accounts, making the firm a significant repository of confidential financial identities.
In 2026, Chatham Asset Management LLC reported a data security incident to the Indiana Attorney General, raising serious concerns regarding the safety of the sensitive information entrusted to its care. While the full mechanics of the intrusion continue to be examined, security breaches within the financial services sector typically involve sophisticated cyberattacks, such as unauthorized network intrusions, ransomware deployments, or third-party vendor compromises that bypass perimeter defenses. In the context of an investment firm, threat actors often target legacy databases, cloud storage repositories, or employee credentials to harvest valuable financial records.
The data compromised in incidents of this nature routinely includes full legal names, Social Security numbers, dates of birth, financial account numbers, banking routing details, and detailed transaction histories. The exposure of this specific combination of financial and personal identifiers creates severe, long-term risks for affected individuals. Social Security numbers and banking details can be weaponized by bad actors to facilitate identity theft, execute unauthorized wire transfers, drain investment accounts, and open fraudulent credit lines. Furthermore, tax-related fraud becomes a significant threat when personal data associated with high-net-worth portfolios is leaked into illicit forums.
As a financial institution operating in Indiana, Chatham Asset Management LLC is bound by rigorous federal and state regulatory frameworks, including the Gramm-Leach-Bliley Act (GLBA) and applicable state data protection statutes. These laws impose strict legal obligations to implement robust administrative, physical, and technical safeguards to protect non-public personal information. The occurrence of a data breach strongly suggests a potential failure in these mandated security controls, whether through unpatched vulnerabilities, weak access management, or inadequate monitoring protocols, which may constitute actionable negligence under the law.
Receiving a data breach notification letter from Chatham Asset Management LLC serves as formal acknowledgment that your private financial and personal records were compromised due to corporate security shortcomings. Legally, this notice establishes standing to participate in class action litigation aimed at holding the firm accountable for failing to safeguard your information. Individuals affected by this breach do not need to wait until financial fraud occurs to take legal action; our firm evaluates these cases on a contingency fee basis, meaning you pay nothing unless we successfully recover compensation on your behalf.
Notification Delay: Approximately 1 month elapsed between the reported date of the security incident and the company's notification to the Attorney General. Courts have found that excessive notification delays independently support legal claims.
Eligibility is broader than most people expect: you do not have to prove money was stolen, only that your information was put at risk. You may qualify if any of these apply:
You received a data breach notification letter from Chatham Asset Management LLC
You were a customer, patient, employee, or client of Chatham Asset Management LLC
Your personal information was stored in Chatham Asset Management LLC's systems
Your Social Security number or driver's license number was exposed
Your financial account, credit card, or banking information was disclosed
You reside in the United States (all 50 states eligible)
That letter is legally required and confirms your data was exposed. It also gives you standing to file a claim.
What your notification letter means & what to do next →Do these four things as soon as possible; each one protects you and strengthens any claim:
Your Chatham Asset Management LLC notification letter is legal evidence. Keep both physical and digital copies somewhere safe — it establishes you were affected and anchors your claim.
Your letter likely includes a monitoring activation code. Use it: free monitoring flags misuse of your data and records the harm for your case.
Freeze your credit with Equifax, Experian and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted whenever you need to apply for credit.
Time limits can forfeit your claim. Have attorneys review your Chatham Asset Management LLC case at no cost — contingency means zero upfront fees.

Several forms of recovery may be available to Chatham Asset Management LLC letter recipients — the exact mix depends on state law and the data types exposed:
Statutory damages exist independent of out-of-pocket loss — California's $100–$750 range is the model other states have followed.
If the breach led to fraudulent charges or unauthorized transactions on your accounts, those losses are recoverable.
Compensation for hours spent monitoring accounts, disputing fraud, freezing credit, and dealing with the aftermath of the breach.
Reimbursement for the cost of credit monitoring services, identity theft protection, and related identity restoration expenses.
SSN and driver's license exposure creates long-term identity theft risk. Courts recognize the ongoing value of this harm and may award damages accordingly.
Exposure of financial account or credit/debit card information entitles victims to recover for actual and potential fraud losses.
Indiana's data breach law (IC 24-4.9) requires companies to notify affected residents and the Attorney General. Indiana residents may pursue damages under the Deceptive Consumer Sales Act for a company's failure to protect personal information.
Other companies have notified the Indiana AG of breaches. Received one of these letters as well? You may have more than one claim.
