Thegentlemen claims data breach at EKEPIS

The ransomware group known as thegentlemen has listed the organization EKEPIS on its leak site. According to an announcement published by the group on August 14, 2026, the threat actors claim that data belonging to the entity has been compromised and leaked.

Ransomware attacks often involve a tactic known as double extortion. In these scenarios, threat actors do not only encrypt an organization's systems to disrupt operations but also steal sensitive information. The attackers then threaten to publish this data on public leak sites if a ransom is not paid. This pressure is designed to maximize the impact on the victim by threatening reputational damage and legal consequences stemming from the exposure of private information.

The claim made by thegentlemen suggests that the organization's data has been exfiltrated. However, it is important to note that the validity of these claims remains uncertain, and there is currently no confirmation regarding the accuracy or the currency of the data involved in this alleged incident.

Details of the alleged leak

Regarding the specific details of the breach, the group has provided very limited information to the public. As of the announcement, there is no information regarding the content of the leaked data, and no screenshots have been provided by the threat actors to prove the theft.

The listing names no specific data types that have been compromised.

Organizational profile

EKEPIS was a former national center in Greece that was responsible for certifying adult educators and lifelong learning providers. The institution's duties and authorities were subsequently absorbed by EOPPEP (National Organisation for the Certification of Qualifications and Vocational Guidance). Consequently, the domain associated with EKEPIS no longer serves as an official resource for the organization's former functions.

Analysis and potential implications

This incident suggests that legacy data or remnants associated with the domain may be targeted by threat actors. Even when an organization is no longer active in its former capacity, the existence of historical data can present a significant security risk. If the alleged data contains personal information, it could lead to secondary risks such as identity theft or targeted phishing for the affected individuals.

While the organization is no longer active, data protection obligations under GDPR may still be relevant in the context of a potential breach. Organizations and entities managing legacy systems must remain vigilant, as dormant data remains a high-value target for cybercriminals seeking to exploit older, potentially less monitored infrastructure.

To defend against such threats, organizations typically implement various defensive measures. These include maintaining robust backup strategies, implementing multi-factor authentication, and ensuring that all legacy systems and data repositories are decommissioned securely. Regular monitoring of the dark web and leak sites can also help organizations identify if their historical data has become the subject of a threat actor's claims.

Information regarding the specific capabilities and methods of the group known as thegentlemen remains limited. At this stage, the primary uncertainty remains whether the threat actor's claims are valid and how much of the information involved is current or outdated.
