What may have been exposed

  • Full Name
  • Social Security Number
  • Date of Birth
  • Mailing Address
  • Email Address
  • Wage and Compensation Information
  • Financial Account Number
  • Tax Return Information
  • Professional Credential Data

Informa, a major group of B2B media, events, and tech intelligence companies, recently filed a supplemental data breach notification with the State of Maine on May 8, 2026. The nature of the breach itself was not specified in the public filing, but it triggered a formal disclosure indicating an incident had occurred within Informa’s systems, affecting personal data.

The public filing indicates that the exposed information includes a range of sensitive personal and professional details. Specifically, the data categories reported as compromised are Full Name, Social Security Number, Date of Birth, Mailing Address, Email Address, Wage and Compensation Information, Financial Account Number, Tax Return Information, and Professional Credential Data.

Such a comprehensive exposure carries significant risks for those affected. With Social Security Numbers, dates of birth, and financial account numbers potentially in the hands of unauthorized parties, individuals face a heightened risk of identity theft, tax fraud, and unauthorized access to their financial accounts. Professional credentials can also be exploited for targeted phishing attacks or corporate espionage.

If you receive a notification regarding this Informa data breach, it is crucial to take protective measures immediately. Consider placing a fraud alert or security freeze on your credit reports with all three major credit bureaus (Equifax, Experian, and TransUnion). Regularly review your financial account statements, credit reports, and explanations of benefits for any suspicious or unauthorized activity.

Additionally, be vigilant against unsolicited emails, texts, or phone calls that claim to be from Informa or other legitimate organizations, as these could be phishing attempts. Do not click on suspicious links or provide personal information unless you have independently verified the sender's legitimacy. These steps, while general, are widely recommended to help mitigate the risks associated with data exposure.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • Freeze your credit

    Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.

  • Guard against tax fraud

    File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.

  • Watch your financial accounts

    Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.

  • Secure your online accounts

    Change the password on any account that reused an exposed password and turn on two-factor authentication wherever it's offered.

  • Stay alert to targeted scams

    Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.

  • Keep your notification letter

    Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
