Informa (including Informa Exhibitions U.S. Construction and Real Estate, Inc., other Informa U.S. entities, and Informa TechTarget) was the subject of a data breach notification filed with the CA Attorney General. The AG filing was recorded on April 17, 2026. The breach or discovery date reported in the filing is August 11, 2025.
From the AG filing description
Informa—encompassing Informa Exhibitions U.S. Construction and Real Estate, Inc., various other Informa U.S. entities, and Informa TechTarget—operates as a global B2B information services, publishing, exhibitions, and digital media powerhouse. The company produces major industry trade shows, high-profile conferences, and specialized market intelligence platforms for sectors ranging from real estate and construction to enterprise technology. To successfully coordinate massive commercial events, manage large-scale digital subscriptions, and facilitate B2B networking, Informa and its subsidiaries routinely collect, process, and store vast repositories of sensitive personally identifiable information (PII) from event attendees, corporate clients, webinar participants, and industry professionals across the United States. In 2026, Informa reported a significant data security incident to the California Attorney General, alerting regulators and consumers to an unauthorized intrusion into its digital infrastructure. For a major enterprise handling high volumes of digital marketing data, participant registrations, and B2B databases, breaches of this magnitude frequently stem from compromised cloud storage environments, third-party vendor vulnerabilities, or sophisticated cyberattacks targeting integrated software platforms. When attackers breach organizations that aggregate immense professional and consumer profiles, they often exploit weak access controls or unpatched system vulnerabilities to gain persistent entry into internal file repositories and customer management databases. The exposure resulting from the Informa data breach involves highly sensitive categories of personal information, which can include full names, email addresses, physical mailing addresses, telephone numbers, and professional credentials, as well as potentially financial transaction data or account login credentials associated with event registrations and digital subscriptions. The compromise of this data creates severe, tangible risks for affected individuals. Exposed email addresses, phone numbers, and professional profiles immediately prime victims for targeted spear-phishing campaigns, corporate identity theft, and sophisticated social engineering attacks designed to compromise business networks or personal finances. Furthermore, if credential hashes or passwords were exposed, victims face widespread credential-stuffing attacks across unrelated online accounts. Under California law, including the California Consumer Privacy Act (CCPA) and state common law doctrines, companies like Informa have an affirmative legal duty to implement and maintain reasonable security procedures and practices appropriate to the nature of the personal information they collect. This duty requires maintaining robust encryption standards, conducting regular vulnerability assessments, and adequately vetting third-party vendors and integrated technology platforms. The occurrence of a successful cyberattack resulting in the unauthorized exfiltration of sensitive PAI strongly suggests potential systemic failures in meeting these statutory and common law obligations, leaving the enterprise vulnerable to legal accountability. Receiving a formal data notification letter from Informa is a formal acknowledgment that your personal information was compromised due to inadequate data security measures. Legally, the receipt of this notice establishes the necessary standing to participate in a class action lawsuit aimed at holding the company accountable for failing to safeguard sensitive data. Under established legal precedents, affected individuals do not need to prove that they have already suffered actual financial fraud or identity theft to seek legal redress; the increased risk of future harm and the invasion of privacy alone are sufficient. Our firm is actively investigating potential class action claims on a contingency fee basis, meaning there are never any out-of-pocket costs or fees unless we successfully recover compensation on your behalf.
Under the California Consumer Privacy Act (CCPA), you may have a legal claim against Informa (including Informa Exhibitions U.S. Construction and Real Estate, Inc., other Informa U.S. entities, and Informa TechTarget) if any of the following apply:
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.
When login credentials are exposed, the costs of downstream account compromises — password managers, security audits, and recovery costs for hijacked downstream accounts — can be recovered. Courts in recent class actions have awarded damages for credential exposure even without proven misuse.
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.
No. Under California Consumer Privacy Act (CCPA) 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.
State statutes of limitations for data breach claims typically run 2–4 years from the date of the breach or its discovery. Because this breach was recently disclosed, the window is open — but acting early preserves your options and strengthens the case.
Accepting free credit monitoring from Informa (including Informa Exhibitions U.S. Construction and Real Estate, Inc., other Informa U.S. entities, and Informa TechTarget) 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 Informa (including Informa Exhibitions U.S. Construction and Real Estate, Inc., other Informa U.S. entities, and Informa TechTarget) during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
Most data breach class actions resolve within 18 to 36 months, though timelines vary by court and complexity. Your participation requires minimal effort — typically completing a claim form. Our office handles all litigation; you are notified when a settlement is reached.
