The Qilin ransomware group has listed the technology company mdm®NT on their leak site, alleging a data breach. This announcement, made on January 2, 2026, marks a new development in the group's ongoing campaign against various sectors.

The claimed attack

According to the claims made by the Qilin threat actors, they have successfully gained access to the systems of mdm®NT. The group asserts that they have managed to exfiltrate data from the organization's internal environment. This listing on the group's platform is considered a potential threat to the organization's operations within the technology sector.

Ransomware leak sites serve as a public stage for threat actors to pressure victims. By listing an organization, these groups aim to damage the victim's reputation and create urgency through the threat of publicizing stolen information. This tactic is a central component of modern cyber extortion campaigns.

Organization profile

MDMNT is a technology company based in Poland. It operates primarily in the fields of software development, IT consulting, and digital solutions.

Analysis and implications

This incident may lead to the exposure of sensitive data held by mdm®NT. Because the organization is based in Poland, obligations regarding data breach notifications and potential administrative fines under GDPR may arise. The use of double extortion tactics by the Qilin group suggests that the organization's operational continuity could be disrupted and that the risk of targeted phishing attacks may increase as a secondary threat.

Double extortion is a method where attackers not only encrypt an organization's data to disrupt operations but also steal sensitive information to use as leverage. If a ransom is not paid, the threat actors threaten to leak the stolen data publicly. This approach increases the pressure on the victim, as the threat extends beyond simple operational downtime to include long-term reputational damage and legal liabilities.

There is a potential risk of identity theft for the organization's customers and employees; therefore, relevant parties may need to enhance their security measures. Organizations facing such threats often focus on strengthening their perimeter defenses, implementing robust multi-factor authentication, and conducting regular security awareness training to mitigate the risk of phishing.

Qilin, also known as Agenda, is a RaaS (Ransomware-as-a-Service) group that has been active since 2022. The group is known for targeting various sectors, including healthcare, employing sophisticated methods to infiltrate and exploit organizations.
