• Ransomware group: radar
• Country: Belgium
• Sector: Transportation
• Announcement date: September 11, 2025

Menten Truck Service N.V., a company based in Belgium, has been listed on a leak site by the threat group known as radar. The threat actor claims to have obtained data belonging to the organization, marking a potential security incident for the Belgian-based service provider.

The claim by radar

On September 11, 2025, the radar group announced that they have listed Menten Truck Service N.V. on their leak site. This announcement serves as a claim of a successful breach by the threat actor. While the group has made this public claim, public information regarding the specific operations and background of the radar group remains limited.

In the context of modern cybercrime, such listings are often part of a double extortion strategy. In these scenarios, threat actors do not only encrypt an organization's systems to disrupt operations but also exfiltrate sensitive information. The threat actors then use the threat of leaking this data on a public site to pressure the victim into paying a ransom. This method increases the leverage of the attacker, as the victim faces not just operational downtime but also significant reputational and legal risks.

Data involved in the listing

Regarding the specific details of the breach, there is no information or screenshot available regarding the nature of the data shared on the leak site. The listing does not provide details concerning the volume of the data or the specific types of files that may have been accessed.

• The listing names no data types.

When organizations face such claims, the lack of immediate transparency regarding the data type makes it difficult to assess the immediate impact. However, the absence of information does not confirm that no data was taken; it simply means the threat actor has not yet provided specific details or evidence to the public.

Organization profile

Menten Truck Service is a truck and commercial vehicle service center based in Hoeselt, Belgium. The company provides maintenance, repair, and technical service solutions for heavy-duty vehicles. As a provider of technical services for commercial transport, the organization plays a role in the logistics and transportation infrastructure of its region.

Potential implications and defensive considerations

If the leak claim is verified, there may be a risk of exposure for personal data belonging to the company's employees or customers. As the organization operates in Belgium, a potential data breach could lead to legal and administrative consequences under the GDPR. The publication of such data may damage the company's commercial reputation and could create a basis for secondary attacks. Furthermore, any contact information that may be included in the leaked data could be utilized for targeted phishing campaigns.

For organizations operating in the transportation and service sectors, several defensive measures are critical to mitigate the risks associated with ransomware and data exfiltration. Implementing robust access controls and multi-factor authentication can help prevent unauthorized entry into sensitive systems. Regular, offline backups are essential for ensuring that operations can be restored in the event of a ransomware attack, though they do not prevent the theft of data itself.

To defend against the secondary risks of data leaks, such as phishing, organizations should focus on employee training and awareness programs. Educating staff on how to recognize sophisticated social engineering attempts is vital, especially if contact information becomes available to attackers. Additionally, maintaining a comprehensive incident response plan allows an organization to react swiftly to a potential breach, potentially minimizing the legal and reputational fallout that follows a public listing on a leak site.
