Global industrial tech firm Sensata Technologies has confirmed a data breach following a ransomware attack in April 2025. The company revealed that sensitive personal and financial information belonging to current and former employees—as well as their dependents—was stolen during the incident.
Ransomware Attack on Sensata Disrupted Operations and Stole Employee Data
Sensata, known for its mission-critical sensors and electrical protection systems, disclosed the breach in a U.S. SEC 8-K filing shortly after the April 6 attack. The ransomware event disrupted shipping, manufacturing, and various business operations.
At the time, the company acknowledged that data had been stolen but could not confirm the extent of the breach.
Further investigation, assisted by external cybersecurity experts, revealed that unauthorized access to the company’s network began on March 28, 2025, and continued until the ransomware was deployed on April 6.
As noted in the notification sent to affected individuals:
“The evidence showed that there was unauthorized activity in our network between March 28, 2025, and April 6, 2025. During that time, an unauthorized actor viewed and obtained files from our network.”
Sensitive Personal and Financial Details Exposed
A detailed review of the stolen files concluded on May 23, 2025, and determined that the exposed data may include a wide range of sensitive information:
- Full name
- Address
- Social Security Number (SSN)
- Driver’s license or state ID number
- Passport number
- Financial and payment card data
- Medical and health insurance details
- Date of birth
The scope of exposed data varies depending on the individual, and both current and former employees of Sensata—as well as their dependents—have been impacted.
Support Offered, But Questions Remain
Sensata is offering one year of credit monitoring and identity theft protection, with instructions included in its notification letters. However, the company has not disclosed how many individuals were affected. No ransomware group has publicly claimed responsibility for the attack.
As of publication, Sensata has not responded to inquiries regarding the breach’s full scale.
With annual revenues exceeding $4 billion and clients in automotive, aerospace, and defense sectors, Sensata’s breach highlights ongoing risks ransomware poses to critical industry suppliers—and the personal data of those who work for them.
