A recent data breach at Takeuchi Manufacturing Incorporated, a leading construction equipment manufacturer, has exposed sensitive personal information of at least one individual in Massachusetts. According to the company’s disclosure, the information exposed includes personally identifiable information (PII). The company reported the breach to the Massachusetts Attorney General’s office on Nov. 26, 2025, as required by state law.
On Oct. 29, 2025, Takeuchi discovered that an unauthorized actor had accessed files containing personal data during a network security incident that occurred around Sept. 17, 2025.
The breach was the result of a ransomware attack carried out by the PLAY ransomware group, which posted on the dark web on Sept. 22, 2025, that they had exfiltrated confidential client documents, payroll data, accounting and tax records, identification documents, and financial information from Takeuchi. The group threatened to publish the stolen data on Sept. 26, 2025.
So far, only one Massachusetts resident was reported as affected. However, the nature of the stolen data and the ransomware group’s claims suggest the breach could have broader implications.
Takeuchi Manufacturing Incorporated’s response
In response to the incident, Takeuchi immediately launched a comprehensive investigation with the help of external cybersecurity experts. The company conducted a forensic analysis and internal review to determine the extent of the breach and identify affected individual
