NOTICE OF DATA BREACH

We are contacting you about a data breach that has occurred at TSE Industries, Inc. together with its affiliated companies, WHK BioSystems, LLC and Duro-Glide Polymer Sheets, LLC.

What Happened?

On May 10, 2025, our IT professionals received an automated alert that some TSE computer servers that store data back-ups had been wrongfully accessed. We have no knowledge as to whether the accessed information has been used in any manner.

What Information Was Involved?

Comprehensive computer backups were accessed exposing all electronic files, including HR and Acctg records from 2022 and earlier. How much earlier is not yet known. No data from 2023 or later appears to have been exposed. An unknown amount of information was accessed, including complete employee records and social security numbers, as well as customer and vendor account information, including bank names and account numbers. TSE only learned that this information was accessed on May 19, 2025 by forensic technicians.

What We Are Doing

In order to remedy the situation and secure all data and records further, TSE has retained a highly specialized electronic data security firm to perform a comprehensive review of TSE’s computer security and to upgrade all security software and systems to the highest level possible utilizing the latest technology. TSE is notifying all those affected by this breach to take immediate steps to protect their data as recommended in this Notice.    

 

What You Can Do

The Federal Trade Commission (FTC) recommends that you place a free fraud alert on your credit file. A fraud alert tells creditors to contact you before they open any new accounts or change your existing accounts. Contact any one of the three major credit bureaus. As soon as one credit bureau confirms your fraud alert, the others are notified to place fraud alerts. The initial fraud alert stays on your credit report for one year. You can renew it after one year. 

Equifax: equifax.com/personal/credit-report-services or 1-800-685-1111

Experian: experian.com/help or 1-888-397-3742

TransUnion: transunion.com/credit-help
or 1-888-909-8872

Ask each credit bureau to send you a free credit report after it places a fraud alert on your file. Review your credit reports for accounts and inquiries you don’t recognize. These can be signs of identity theft. If your personal information has been misused, visit the FTC’s site at IdentityTheft.gov to report the identity theft and get recovery steps. Even if you do not find any suspicious activity on your initial credit reports, the FTC recommends that you check your credit reports periodically so you can spot problems and address them quickly. 

You may also want to consider placing a free credit freeze. A credit freeze means potential creditors cannot get your credit report. That makes it less likely that an identity thief can open new accounts in your name. To place a freeze, contact each of the major credit bureaus at the links or phone numbers above. A freeze remains in place until you ask the credit bureau to temporarily lift it or remove it. 

See the FTC’s website, IdentityTheft.gov/databreach, about steps you can take to help protect yourself from identity theft. The steps are based on the types of information exposed in this breach.
