BMGP Groupe listed on dragonforce ransomware leak site

• Ransomware group: dragonforce
• Country: France
• Announcement date: September 24, 2026

The French manufacturer BMGP Groupe has been listed on the leak site of the ransomware group known as dragonforce. The threat actor group has published an announcement claiming that the organization's data has been compromised in a recent cyberattack.

The details of the claim

According to the announcement published by the dragonforce group on September 24, 2026, the group claims to have successfully targeted the organization. The group asserts that the attack took place on September 23, 2026, one day prior to the public announcement on their leak site. While the group has taken responsibility for the listing, the specific methods used to gain access to the network have not been detailed in the public announcement.

Ransomware attacks often involve a tactic known as double extortion. In this model, attackers do not merely encrypt a victim's files to disrupt operations; they also exfiltrate sensitive data to use as leverage. By threatening to release this stolen information on a public leak site, the attackers aim to pressure the organization into paying a ransom to prevent the exposure of confidential information. This approach increases the pressure on companies, as the threat of a data leak can cause significant reputational and legal damage even if the company can restore its systems from backups.

Data involved in the alleged breach

The dragonforce group has provided limited information regarding the specific contents of the stolen data. The group claims that the total volume of the compromised data is 38.73 GB. However, the announcement does not provide a specific list of files or details regarding the exact nature of the information that has been taken.

• Total claimed data size: 38.73 GB

The listing does not specify the types of files involved, such as whether they consist of financial records, employee information, or technical blueprints. The absence of a detailed file list is common in early stages of a leak site announcement, where groups may only provide the total data size to demonstrate the scale of the theft before potentially releasing more details or negotiating.

About BMGP Groupe

BMGP Groupe, operating under the name Polyresine, is a French manufacturer that has been established since 1972. The company specializes in the formulation, production, and distribution of synthetic resins and high-performance technical polymers. Their industrial applications are broad, providing tailored chemical solutions for sectors requiring specialized coatings, waterproofing, and industrial flooring.

Potential impact and industry considerations

The alleged leak may create negative impacts on the company's operational continuity and commercial reputation. Because the company operates in France, the potential exposure of personal or commercial confidential data could lead to legal consequences under the General Data Protection Regulation (GDPR). Organizations operating within the European Union must adhere to strict data protection standards, and breaches involving personal data can result in significant regulatory scrutiny and fines.

Furthermore, the dragonforce group reportedly follows a model of providing infrastructure to affiliates, which suggests that the attack may have been carried out by different actors using the group's tools and services. Given the company's position in the industrial chemistry sector, the leakage of technical specifications or client information could lead to secondary risks and a loss of competitive advantage. In specialized manufacturing, technical formulas and client lists are critical assets that define a company's market position.

To defend against such threats, organizations in the industrial sector often implement defensive measures such as robust network segmentation, multi-factor authentication, and continuous monitoring of data exfiltration patterns. Maintaining offline, immutable backups is also a standard practice to ensure operational continuity in the event of a ransomware encryption event. It is important to note that the accuracy and scope of the alleged data have not yet been verified by independent sources.
