Lynx ransomware group claims breach of Delta Screen & Filtration

The threat actor known as Lynx has listed the manufacturing company Delta Screen & Filtration on its dedicated leak site. Through this announcement, the group claims to have successfully compromised the company's internal data and has provided sample documents as evidence of the breach.

The announcement, which appeared on January 29, 2025, includes a description of the company's business operations alongside screenshots of the allegedly exfiltrated files. The presence of these screenshots serves as the group's method of proving they have access to the organization's private information.

Details of the alleged data exfiltration

The information released by the group consists of previews of documents that are claimed to be related to the company's business operations and contractual agreements. While the group has provided these visual proofs, there is no detailed information regarding the full scope or specific types of the exfiltrated data available at this time. No specific file counts or the total size of the stolen data have been disclosed by the threat actor.

Based on the available evidence provided in the leak site announcement, the following types of information are reported to be affected:

About Delta Screen & Filtration

Delta Screen & Filtration is a manufacturing company that produces high-rigidity flat screens and industrial filtration solutions for catalyst support applications. The company specializes in designing precision-welded and durable screens that are tailored to meet the specific technical requirements of its diverse client base.

Risk assessment and industry implications

This alleged breach by the Lynx group may pose a significant risk of exposing the company's trade secrets and sensitive client agreements. Because the company is based in the United States, potential data breaches of this nature could lead to legal scrutiny under state-level data protection regulations and industry-specific compliance requirements. Furthermore, the exposed documents could potentially be utilized by malicious actors in targeted phishing campaigns directed at employees and business partners.

The Lynx group, which emerged in 2024, shows similarities to INC Ransom and appears to employ double-extortion tactics to pressure its victims. Double extortion is a common ransomware tactic where attackers not only encrypt a victim's data to disrupt operations but also steal sensitive information to threaten its public release unless a ransom is paid.

For organizations operating in the manufacturing sector, such incidents highlight the importance of robust cybersecurity frameworks. Common defensive steps for organizations facing these threats include maintaining offline backups, implementing strict access controls, and conducting regular employee training to recognize phishing attempts. Strengthening network monitoring and ensuring compliance with regional data protection laws are also critical components of a modern defensive posture against evolving ransomware groups.
