Kosmos Management LLC was the subject of a data breach notification filed with the IN Attorney General. The AG filing was recorded on December 26, 2025. The breach or discovery date reported in the filing is January 23, 2025.
From the AG filing description
Kosmos Management LLC operates as a specialized property management and real estate asset firm, overseeing commercial and residential communities, tenant portfolios, and comprehensive financial administration. In the course of managing these complex portfolios, the company routinely collects, processes, and stores vast quantities of confidential records pertaining to tenants, prospective buyers, employees, and vendors. This operational necessity requires Kosmos Management LLC to maintain deep repositories of sensitive Personally Identifiable Information (PII) and Financial Information (FI) required for lease processing, background checks, credit evaluations, and monthly rent or mortgage transactions, making them a high-value target for malicious actors. In 2025, Kosmos Management LLC reported a significant data security incident to the Indiana Attorney General, alerting the state's residents to an unauthorized compromise of its IT infrastructure. While specific technical forensics continue to emerge, incidents affecting property management and asset firms typically involve sophisticated ransomware attacks, unauthorized credential harvesting, or vulnerabilities within third-party cloud hosting and vendor portals. These vectors allow threat actors to bypass perimeter defenses, infiltrate central databases, and exfiltrate substantial volumes of private records before detection occurs, highlighting systemic vulnerabilities in corporate data stewardship. Preliminary indications suggest the compromised data ecosystem included a dangerous mixture of core identifiers, such as Full Names, Dates of Birth, Social Security Numbers, banking details, and residential history. The exposure of Social Security Numbers combined with banking and routing details creates an immediate and severe risk of financial fraud, synthetic identity creation, and unauthorized account takeovers. Furthermore, with extensive lease applications and background screening files exposed, victims face long-term threats to their credit health, as bad actors can leverage this data to open fraudulent lines of credit, divert rental payments, or execute targeted phishing schemes. As an entity handling sensitive consumer and tenant records, Kosmos Management LLC operated under strict legal obligations to implement robust administrative, physical, and technical safeguards to secure its digital environment. These duties are rooted in the Federal Trade Commission (FTC) Act, which prohibits unfair and deceptive trade practices regarding data security, alongside applicable Indiana state data protection statutes. By failing to prevent unauthorized access and exfiltration, Kosmos Management LLC may have breached these foundational legal standards, exposing the organization to substantial liability for failing to maintain adequate security controls. Receiving a formal data breach notification letter from Kosmos Management LLC serves as an official admission that your private records were compromised due to corporate security failures. Under modern jurisprudence, the receipt of such a notification often establishes legal standing to participate in a class action lawsuit, allowing affected individuals to seek justice and compensation without needing to prove that actual financial loss has already occurred. Our law firm is currently investigating potential claims against Kosmos Management LLC on a contingency fee basis, meaning there are never any out-of-pocket costs or fees unless we successfully recover compensation on your behalf.
Based on the data types reported in this filing:
Your SSN is the master key to your identity. Once exposed, criminals can open new lines of credit, take out loans, or file taxes in your name.
Combined with a name and other leaked data, date of birth helps criminals pass identity verification questions at banks and government agencies.
You may have been affected by the Kosmos Management LLC data breach if:
Common categories of compensation in data breach class actions
Courts recognize that the time spent monitoring accounts, placing credit freezes, and dealing with the aftermath of a breach has real economic value. This category of damages is recoverable even without direct financial loss.
Professional credit monitoring services cost $10–$40 per month. Identity theft restoration services, if needed, can cost hundreds of hours and thousands of dollars. Courts have awarded these costs as direct damages in SSN breach cases.
Direct financial losses resulting from the breach — unauthorized charges, fraudulent transfers, or fees incurred through fraud — are recoverable as compensatory damages. Banks may reverse some charges; a class action recovers the remainder and associated costs.
Data breach victims regularly report anxiety, loss of sleep, and ongoing fear of identity theft. These non-economic harms are cognizable injuries in data breach litigation, particularly in cases involving SSN or medical record exposure.
Note: an attorney general breach filing does not by itself establish a settlement fund, a payment amount, or a claim deadline. If an official settlement notice is later issued, rely on that notice for payment details and deadlines.
Applicable State Law
This breach was reported under the Indiana data breach notification law, which mandates notification and establishes your right to seek damages.
No. Under Indiana data breach notification law and federal law, the unauthorized exposure of your personal data — regardless of whether it has been actively misused — can be sufficient grounds for a claim. The breach itself is the injury.
Nothing. The Law Office of David S. Harris handles data breach cases on contingency — you pay zero upfront and owe nothing unless compensation is recovered.
Immediately place a free credit freeze at all three bureaus (Equifax, Experian, TransUnion). A freeze blocks new accounts from being opened in your name. Then file a complaint with the FTC at IdentityTheft.gov and contact our office — SSN exposure is one of the most serious breach types.
Banks may reverse fraudulent charges, but they are not obligated to compensate you for time lost, stress, or indirect damages. A class action claim against the breached company can recover those additional categories of harm.
Statutes of limitations for data breach claims vary by state but typically run 2–4 years. Depending on when you learned of the breach, you may still have time. Contact our office for a free eligibility review — there is no cost to find out.
Accepting free credit monitoring from Kosmos Management LLC does not waive your right to pursue legal action unless you signed a specific release waiving claims. In most cases, victims who accepted monitoring can still file.
Not necessarily. Many data breach victims are never notified directly. If your personal information was held by Kosmos Management LLC during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
