• Announcement date: August 15, 2025

The Qilin ransomware group has listed the Poland-based manufacturing company marma.com.pl on its leak site, claiming to have exfiltrated corporate data. The announcement, made on August 15, 2025, suggests that the group has successfully breached the organization's internal networks.

The claimed attack and event details

According to the announcement made on August 15, 2025, the Qilin ransomware group alleges a significant data breach involving marma.com.pl. The group claims to have gained unauthorized access to the organization's internal networks, allowing them to obtain various corporate files. This breach, as alleged by the group, suggests that sensitive information belonging to both employees and clients may have been compromised during the intrusion.

Ransomware groups often utilize leak sites to pressure victims into paying ransoms. These sites serve as a public gallery where the group posts information about their targets. When a group claims to have accessed internal networks, it typically implies that they have bypassed perimeter defenses to reach sensitive file servers or databases. This type of activity is a hallmark of modern cyber extortion campaigns.

Data types involved in the alleged leak

The Qilin group claims that the exfiltrated information includes a wide range of sensitive data. The content of the leak is said to involve personal details of staff members, information regarding the company's clientele, and various internal business records. Specifically, the group claims the following types of data were obtained:

• Employee personal data (names, addresses, phone numbers, bank account details)
• Client information
• Financial records
• Production process data

The inclusion of such diverse data types highlights the potential impact of the breach. When personal identifiers and financial details are involved, the risks extend beyond the immediate corporate environment to the individuals whose data was targeted.

About marma.com.pl

MARMA Polskie Folie is one of the largest plastics processors in Europe. The company produces products for agriculture, horticulture, construction, and packaging industries, and employs more than 1,000 people.

Analysis and industry implications

This incident may increase the risk of identity theft and fraud for employees and clients of marma.com.pl. Because the company is based in Poland, the breach may result in legal consequences and administrative fines under the EU General Data Protection Regulation (GDPR). The regulatory landscape in Europe places heavy emphasis on the protection of personal data, and breaches involving sensitive employee and client information often trigger rigorous investigations by data protection authorities.

The Qilin group is known as a Ransomware-as-a-Service (RaaS) entity active since 2022, targeting various sectors. This group employs double-extortion tactics, a method where attackers not only encrypt the victim's data but also steal it to threaten its public release. The publication or sale of the exfiltrated data could trigger secondary risks, such as reputational damage or further targeted attacks against the company's partners.

Furthermore, the exposure of technical data within the manufacturing sector may harm the company's competitive advantage and weaken supply chain security. For manufacturing organizations, the loss of technical details regarding production processes can be devastating, as it may reveal proprietary methods or vulnerabilities in the production line. To defend against such threats, organizations in this sector often implement multi-factor authentication, network segmentation, and continuous monitoring of internal traffic to detect unauthorized access to sensitive segments of the network.
