Knowledge Research Center disclosed a data security incident to the California Attorney General on September 2, 2026, triggering legally mandated notification letters. If you are one of the people who received Knowledge Research Center's letter, your data may have been exposed and you could be entitled to compensation.
The California Attorney General filing confirms the breach notice — not a court case. Dollar amounts and deadlines are shown only when a verifiable court filing supports them — nothing on this page estimates or guarantees a result.
Records filed with the California AG show that Knowledge Research Center confirmed exposure of the information below:
These categories are what make the exposure actionable. Sensitive data types carry greater legal weight.
Knowledge Research Center operates at the intersection of academic inquiry, market intelligence, and proprietary data analytics, serving as a repository for extensive information compiled from research subjects, corporate partners, and institutional participants. Because of its core mission to aggregate, process, and analyze complex datasets, the organization routinely collects and retains vast quantities of sensitive personally identifiable information (PII). This repository often includes detailed demographic profiles, proprietary survey responses, institutional affiliation records, and, in many cases, financial and credentialing data necessary for participant compensation, grant administration, and cross-border research initiatives. The sheer volume and depth of the records maintained by Knowledge Research Center make it a high-value target for malicious actors seeking to exploit centralized data assets.
In 2026, Knowledge Research Center formally reported a significant security incident to the California Attorney General, signaling a critical breakdown in its digital infrastructure. While the exact vectors of the compromise continue to be analyzed, incidents affecting data-intensive research institutions typically involve sophisticated external intrusions, unauthorized exploitation of database vulnerabilities, or third-party vendor compromises that bypass perimeter security controls. In many instances, threat actors leverage advanced credential stuffing or targeted malware to gain persistent access to legacy research servers, where vast archives of unencrypted or inadequately segmented data are stored. Organizations of this type often grapple with complex network perimeters, making the detection of unauthorized data exfiltration exceptionally difficult once a breach occurs.
The exposure resulting from the Knowledge Research Center incident involves categories of data that carry severe, long-term risks for affected individuals. Compromised datasets of this nature frequently include full names, dates of birth, Social Security numbers, contact addresses, and institutional login credentials. The exposure of Social Security numbers and birth dates provides cybercriminals with the foundational elements necessary to commit full-scale identity theft, open fraudulent financial accounts, or file unauthorized tax returns. Furthermore, the leakage of specialized research participant records or corporate metadata can expose individuals to targeted phishing campaigns, social engineering attacks, and reputational harm, as bad actors leverage context-specific information to craft hyper-realistic fraud schemes.
As an entity operating within California, Knowledge Research Center is bound by stringent statutory obligations under the California Consumer Privacy Act (CCPA) and state common law principles of negligence, which require businesses to implement and maintain reasonable security procedures and practices appropriate to the nature of the personal information. The occurrence of a widespread data breach strongly indicates a failure to adhere to these foundational legal standards. Failing to properly patch systems, encrypt sensitive repositories, or monitor network traffic for anomalous behavior constitutes a breach of the duty of care owed to individuals whose data was entrusted to the institution for research and analytical purposes.
Receiving an official data breach notification letter from Knowledge Research Center serves as formal legal acknowledgment that your personal information was compromised due to inadequate data security safeguards. Under modern class action jurisprudence, the receipt of such a notice and the resulting imminent risk of identity theft establish the necessary legal standing to pursue claims against the organization, even before financial loss materializes. Our firm is actively investigating potential class action claims on behalf of affected individuals. We handle these cases on a strict contingency fee basis, meaning you pay nothing out of pocket, and our firm only recovers fees if a successful recovery is secured on your behalf.
Notification Delay: Approximately 2 months 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.
Many people wrongly assume a claim requires proven fraud. The law recognizes data exposure alone as harm. See which of these describes your situation:
You received a data breach notification letter from Knowledge Research Center
You were a customer, patient, employee, or client of Knowledge Research Center
Your personal information was stored in Knowledge Research Center's systems
Your Social Security number or driver's license number was exposed
Your financial account, credit card, or banking information was disclosed
Your login credentials or passwords were exposed
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 Knowledge Research Center 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.
Place security freezes at all three bureaus — Equifax, Experian, TransUnion. New-account fraud dies at the freeze; you can unfreeze temporarily for legitimate applications.

Compensation in a case like Knowledge Research Center's depends on where you live, what was exposed, and how the company responded. Common recovery categories:
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.
The time you lost to credit freezes, fraud disputes, and account monitoring counts as a recoverable inconvenience.
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.
California's Consumer Privacy Act (CCPA) and Consumer Privacy Rights Act (CPRA) provide residents with among the strongest data breach rights in the nation, including statutory damages of $100–$750 per consumer per incident.
These organizations also reported breaches to the California Attorney General. If their letters reached you too, each may carry its own claim.
