Power Curbers targeted by sinobi ransomware group

The manufacturing company Power Curbers has been listed on the leak site of the sinobi ransomware group. The threat actor known as sinobi added Power Curbers to its leak site on December 16, 2025. In the listing, the group claims that the organization's data has been encrypted.

Ransomware attacks often involve a tactic known as double extortion, where attackers not only encrypt an organization's files to disrupt operations but also threaten to leak sensitive information if a ransom is not paid. This pressure is designed to force companies into compliance by threatening their reputation and legal standing. Leak sites serve as the public stage for these threats, where groups post names of victims to increase visibility and pressure.

Details of the claim

The listing provided by the sinobi group specifies a ransom demand of 23,300,000 USD. This significant amount suggests that the actor may be aiming to exert significant financial pressure on the organization. While the group has made these claims, information regarding this specific group remains limited in the public domain.

The provided evidence for the attack includes screenshots that purportedly show a server management dashboard. However, despite these images, there is no detailed information regarding the specific nature of the compromised data. The listing names no specific data types that have been exfiltrated or encrypted.

Impact and organizational risks

The encryption of the organization's data may lead to disruptions in operational continuity. For companies in the manufacturing sector, such disruptions can impact supply chains and production schedules. Furthermore, the high ransom demand highlights the financial stakes involved in modern ransomware negotiations.

As a United States-based entity, potential data breaches may fall under the scope of state-level privacy laws and notification requirements. Organizations must navigate complex legal landscapes when a breach occurs, as different jurisdictions have varying rules regarding when and how victims must be notified. Secondary risks may include the potential use of any leaked sensitive corporate data for identity theft or targeted phishing attacks.

To defend against such threats, organizations typically implement various security measures. These include maintaining robust backup systems to ensure data can be restored without paying a ransom, implementing multi-factor authentication to prevent unauthorized access, and conducting regular employee training to recognize phishing attempts. Continuous monitoring of network traffic can also help identify suspicious activity before it escalates into a full-scale encryption event.
