Sensata Technologies, an industrial technology company that makes sensors and electrical protection components, has disclosed a data security incident tied to a ransomware attack. The company says it discovered on April 6, 2025 that certain servers on its network had been encrypted with ransomware. A subsequent investigation, aided by an outside cybersecurity firm, found that an unauthorized actor had accessed the network between March 28, 2025 and April 6, 2025 and viewed and obtained files during that window. Sensata completed its review of those files on May 23, 2025 and determined that some may have contained personal information belonging to the people it is now notifying.
The letter states it was sent to current or former Sensata employees, dependents of current or former employees, or individuals whose information Sensata held for another business-related reason. Sensata has not stated a total number of people affected in the letter provided.

What should you do now?
- Enroll in the free Experian IdentityWorks credit monitoring and identity restoration offer before the deadline in your letter — activation requires the code Sensata provided and will not affect your credit score.
- Because Social Security numbers, driver’s license or passport numbers, and financial account details may have been exposed, consider placing a free security freeze with Equifax, Experian, and TransUnion so no new credit accounts can be opened in your name without your consent.
- Place an initial fraud alert on your credit file, which is free and requires only contacting one of the three credit bureaus.
- Review bank, credit card, and health insurance statements closely over the next 12 to 24 months for any charges or claims you don’t recognize.
- Order your free annual credit reports at annualcreditreport.com and check them for accounts or inquiries you didn’t authorize.
- Given the mix of financial and medical information involved, consider signing up for a service like Aura or LifeLock, which can alert you if your information appears elsewhere.
- If you spot signs of fraud, file a report with the FTC at identitytheft.gov and with your local police department, and keep a copy for your records.
If you have questions, Sensata Technologies can be reached at 855-260-8081, Monday through Friday between 9:00 a.m. and 9:00 p.m. Eastern Time, and Experian’s customer care team is available at (833) 931-7577 for enrollment or identity restoration support.
