Empire Screen Printing listed on sinobi ransomware leak site

• Ransomware group: sinobi
• Country: United States
• Sector: Manufacturing
• Announcement date: December 22, 2025

The United States-based manufacturing company Empire Screen Printing has been listed on the leak site of the sinobi ransomware group. This announcement, which appeared on the group's platform, indicates a targeted cyberattack aimed at the organization's digital infrastructure.

The claims made by sinobi

The threat actor known as sinobi claims to have compromised data belonging to Empire Screen Printing. According to the announcement published on the group's leak platform, the institution's files have been encrypted by the attackers. This listing occurred on December 18, 2025, and serves as a public notification from the threat actor regarding the alleged compromise.

Ransomware attacks of this nature often involve a process known as double extortion. In such scenarios, attackers do not merely encrypt an organization's files to disrupt operations, but they also claim to have exfiltrated sensitive information. The threat of releasing this stolen data on a public leak site is used as leverage to pressure the victim into paying a ransom. While the encryption of files is a primary method of disruption, the threat of data exposure adds a layer of reputational and regulatory risk to the incident.

Data involved in the incident

The listing provided by the sinobi group includes a screenshot indicating that the institution's files have been encrypted. However, there is no detailed list regarding the specific types of data compromised in this incident.

• No specific data types were named in the listing.

In many ransomware incidents, the lack of immediate detail regarding the specific file types or the volume of data stolen can make it difficult for organizations to assess the immediate scope of the breach. Without a detailed inventory of the compromised files, the full extent of the exposure remains unclear to the public and the affected entity.

Organization profile

Empire Screen Printing is a manufacturing company that provides a variety of specialized printing services. Their service portfolio includes screen printing, flexography, digital printing, and doming services. The company serves a diverse customer base located across the United States.

Impact and industry implications

This incident suggests that Empire Screen Printing's operational continuity may have been disrupted. The encryption of files could pose significant risks to the institution's business operations and the security of customer data. As a company operating in the United States, potential data breaches may trigger reviews by state-level data protection laws and regulatory bodies.

Beyond the immediate operational disruption, secondary risks may include the potential use of leaked data for identity theft or targeted phishing attacks against the organization or its clients. For companies in the manufacturing sector, such attacks can lead to significant downtime and loss of intellectual property or proprietary processes.

To defend against such threats, organizations typically implement a multi-layered security strategy. This includes maintaining regular, offline backups to ensure data can be restored without paying a ransom, and implementing robust endpoint detection and response (EDR) systems to identify malicious activity. Furthermore, strict access controls and regular employee training on phishing awareness are essential components of a modern defensive posture. Public information regarding the sinobi group remains limited, making it difficult to attribute the attack to a specific known threat actor profile.
