Sinobi group claims attack on Clean Air
The threat actor group known as sinobi has listed Clean Air on their leak site, claiming a ransom demand of 5 million dollars. This announcement, made on December 9, 2025, suggests a significant targeting of the organization's digital infrastructure.

The threat actors claim to have successfully accessed the organization's operational data. While the group has made these claims, information regarding the specific identity and background of the sinobi group remains limited.

While the group has asserted that they have compromised operational information, the specific details regarding the volume of data or the exact number of files involved have not been provided by the attackers.

About Clean Air
Clean Air is a United States-based organization operating within the manufacturing sector. The company, also referred to as Baker Co., specializes in the engineering, testing, and manufacturing of laboratory safety equipment. With over 100 years of experience, the company serves the biotechnology and life sciences sectors. Their product range includes critical equipment such as biological safety cabinets, clean benches, and pharmaceutical isolators.
Implications and industry risks
This incident may pose a threat to the organization's operational continuity and the security of its intellectual property. Because the company is a US-based manufacturing firm, a potential data breach could trigger legal obligations under state-level data protection laws and industry-specific regulations. The high ransom demand may indicate that the attackers are targeting the organization's financial capacity.
Given the company's service to the biotechnology and pharmaceutical sectors, the incident could lead to secondary risks such as supply chain attacks or targeted phishing campaigns. The exposure of the organization's data could result in a loss of customer trust and long-term commercial damages.
In general, ransomware attacks often utilize double extortion tactics, where attackers not only encrypt files to disrupt operations but also steal sensitive data to threaten its public release. This increases the pressure on organizations to meet ransom demands. To defend against such threats, organizations typically implement robust backup strategies, enforce multi-factor authentication, and conduct regular security awareness training to mitigate the risk of initial access through phishing.
