PROSPER MARKETPLACE, INC. was the subject of a data breach notification filed with the IL Attorney General. The AG filing was recorded on September 1, 2025.
From the AG filing description
Prosper Marketplace, Inc. operates as a prominent financial technology company and online peer-to-peer lending platform, connecting individual borrowers with institutional and retail investors. Because of its core business model, Prosper acts as a central repository for vast quantities of highly sensitive financial and personally identifiable information. To facilitate loan underwriting, credit evaluations, debt consolidation, and investment management, the platform routinely collects, processes, and stores comprehensive dossiers on consumers. This includes intricate financial histories, banking details, and government-issued identification numbers, making the company an extremely attractive target for malicious cyber actors seeking to exploit high-value financial data. In 2025, Prosper Marketplace reported a significant security incident to the Illinois Attorney General, signaling a critical breakdown in its digital defenses. In the fintech and lending sector, breaches of this magnitude typically involve sophisticated cyberattacks such as unauthorized access to internal databases, third-party vendor compromises, or credential-stuffing campaigns that penetrate customer portals. Financial institutions and online lenders maintain extensive digital perimeters, and any vulnerability in their infrastructure—whether through software misconfigurations, compromised API endpoints, or exploited zero-day flaws—can allow unauthorized third parties to infiltrate secure environments and exfiltrate confidential consumer files undetected for extended periods. The exposure resulting from the Prosper Marketplace data breach involves critical categories of personal data that pose severe, long-term risks to affected consumers. Exposed information frequently includes Full Names, Social Security Numbers, dates of birth, financial account numbers, banking routing numbers, credit scores, and detailed transaction histories. The compromise of Social Security Numbers and banking details creates an immediate and acute danger of financial account takeover, unauthorized credit applications, fraudulent loan originations, and synthetic identity theft. When cybercriminals obtain this combination of financial and identifying markers, victims face years of potential monetary loss, ruined credit standings, and persistent administrative burdens as they attempt to untangle fraudulent activities from their legitimate financial lives. As a financial services provider handling sensitive consumer credit and banking data, Prosper Marketplace was bound by stringent legal obligations to maintain robust, multi-layered cybersecurity measures. Under the Gramm-Leach-Bliley Act (GLBA) and applicable state data protection laws, financial institutions are legally mandated to implement comprehensive safeguards to protect consumer nonpublic personal information against foreseeable threats and unauthorized access. The occurrence of a data breach of this scale strongly indicates a potential failure of these statutory obligations, raising serious questions about whether the company utilized adequate encryption standards, maintained rigorous access controls, or properly vetted third-party vendors with access to its network. Receiving a data breach notification letter from Prosper Marketplace is a formal acknowledgment that your private information was compromised due to corporate security failures, and it serves as the foundation for legal standing to participate in a class action lawsuit. Class members do not need to prove that they have already suffered direct financial loss or identity theft to seek legal redress; the increased risk of future harm and the forced expenditure of time and resources to monitor credit are legally actionable injuries. Our firm investigates these cases on a contingency fee basis, meaning affected individuals pay absolutely no out-of-pocket costs and owe no legal fees unless we successfully recover compensation on your behalf.

Common categories of compensation in data breach class actions
The hours spent responding to a data breach — canceling accounts, contacting credit bureaus, updating passwords, and investigating fraud — represent compensable economic harm in data breach litigation.
Once your SSN is exposed, protection becomes an ongoing expense. Plaintiffs in data breach settlements have recovered costs for credit freezes, identity protection subscriptions, and time spent dealing with fraudulent accounts — sometimes covering multiple years of exposure.
Fees charged to close and reopen accounts, issue replacement cards, or dispute fraudulent transactions are recoverable in data breach litigation. So are the costs of overdrafts, late payments, and credit damage caused by unauthorized activity.
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 Illinois Personal Information Protection Act (PIPA), which mandates notification and establishes your right to seek damages.
No. Under Illinois Personal Information Protection Act (PIPA) 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 PROSPER MARKETPLACE, INC. 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 PROSPER MARKETPLACE, INC. during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
