Sensata Technologies reports data breach impacting employee information

U.S. industrial technology company Sensata Technologies has begun notifying current and former employees of a significant data security incident that exposed their sensitive personal information.

 

Headquartered in Attleboro, Massachusetts, Sensata is a leading global industrial technology company that develops, manufactures, and sells sensors, electrical protection components, and other products that are used in mission-critical systems and applications that create valuable business insights for customers and end users.

 

In a filing with the U.S. Securities and Exchange Commission (SEC), Sensata said that on April 6, the company suffered a significant ransomware attack that involved threat actors infiltrating the company’s internal network and deploying malware to encrypt systems, rendering them inaccessible.

 

The company immediately launched an investigation, with assistance from external cyber security experts, to determine the scope of the incident. It also took steps to contain the incident, including proactively taking its network offline and notified relevant law enforcement agencies about the incident.

 

On June 5, in a filing with the Office of Maine Attorney General, Sensata said its investigation has revealed that threat actors breached its network between March 28, 2025 and April 6, 2025 and exfiltrated the sensitive personal information of its customers.

 

The compromised data included names, dates of birth, addresses, Social Security numbers, tax identification numbers, driver’s license numbers or state-issued identification card numbers, passport numbers, other government-issued identification numbers, financial account information, payment card information, medical information, and health insurance information.

 

Sensata is yet to share the number of affected individuals.

 

The company has advised all affected individuals to regularly monitor their credit reports, account and benefit statements and report any suspicious activity to law enforcement authorities, including the police and the state attorney general.

 

It has also offered one year of complimentary identity protection and credit monitoring services through Experian to all affected individuals.

 

At the time of publishing, no known hacker group claimed responsibility for the cyber attack on Sensata. The technology company also did not share details on who was behind the attack, how much data was compromised, or whether it has received a ransom demand.
