Sensata Technologies, a major supplier to the automotive, industrial, and aerospace sectors, has fallen victim to a ransomware attack that has caused significant operational disruptions across the company.
The Attleboro, Massachusetts-based sensor manufacturer filed a disclosure with the Securities and Exchange Commission (SEC) on Wednesday, revealing that the cyberattack was first detected on April 6.
According to the filing, the ransomware incident resulted in the encryption of files stored on multiple company devices.
“On April 6, 2025, Sensata Technologies Holding plc experienced a ransomware incident that has encrypted certain devices in the Company’s network,” the company said.
“Upon discovery, Sensata immediately activated its response protocols, implemented containment measures, including proactively taking its network offline, and launched an investigation with the assistance of third-party cybersecurity professionals. In coordination with legal counsel, the Company has notified law enforcement about the matter and is supporting its investigation.”
Sensata, which employs over 18,000 people across operations in 14 countries, reported that the attack has temporarily impacted critical business functions including shipping, receiving, manufacturing production, and various support operations.
While the company has implemented interim measures to restore certain functions, the timeline for complete recovery remains uncertain.
More concerning for the global sensor giant is evidence that threat actors have exfiltrated company files during the attack. An investigation is currently underway to determine the exact nature and scope of the data breach.
In its SEC filing, Sensata provided limited reassurance regarding the financial impact of the incident, stating it does not expect the attack to materially affect its financial results or operations for the second quarter.
“As of the date of this Form 8-K, Sensata does not expect this incident to have a material impact on the Company’s financial results and operations for the three months ended June 30, 2025,” it said.
However, the company cautioned that “the full scope and impact of this incident is not yet known and could result in a future determination that the incident will be material to the Company’s financial statements and results of operations.”
The identity of the ransomware group behind the attack remains unknown, with no cybercrime organization publicly claiming responsibility at this time.
Security experts suggest this could indicate that negotiations between Sensata and the attackers are ongoing, with threat actors likely to publicize the attack on leak sites only if ransom demands are not met.
This incident comes amid a rising tide of ransomware attacks targeting industrial and manufacturing companies that provide critical components to global supply chains.
The situation continues to develop as Sensata works to restore operations and assess the full impact of the breach.
