Kenworth Del Sur targeted by Hunters ransomware group

Hunters claims responsibility for attack on Kenworth Del Sur

The threat actor known as Hunters has listed the Mexican automotive dealership Kenworth Del Sur on its dedicated leak site. According to the announcement, the group claims to have successfully compromised the organization's systems, resulting in both the encryption of internal data and the exfiltration of sensitive information. This incident follows a pattern of double extortion, a common ransomware tactic where attackers not only lock an organization's files to disrupt operations but also steal data to use as leverage for ransom demands.

The announcement was made on April 25, 2025, with the group claiming the attack took place on the same day. While the group has threatened to publish the acquired data, they have not disclosed a specific ransom demand. This type of threat is designed to maximize pressure on the victim by threatening the public exposure of proprietary or sensitive information.

Details of the claimed data exfiltration

The Hunters group has provided specific details regarding the volume of information they claim to have stolen during the breach. While the specific nature or content of the files has not been disclosed by the attackers, the scale of the theft is significant. The group's announcement includes a screenshot intended to validate their claims regarding the stolen data.

According to the group's claims, the exfiltrated data consists of the following:

• Total file count: 122,328 files
• Total data size: 96.3 GB

The lack of specific information regarding the types of files stolen—such as whether they are financial records, employee details, or customer databases—is a common occurrence in initial leak site postings. Organizations facing such threats often monitor these sites closely to determine the potential impact on their operations and regulatory standing.

About Kenworth Del Sur

Kenworth Del Sur is an automotive dealership located in the state of Sonora, Mexico. The organization serves as an authorized representative of the Kenworth brand under the PACCAR group. Its primary business operations include providing sales, service, and spare parts for heavy-duty trucks, making it a key player in the regional logistics and transportation sector.

Analysis and potential impact

The Hunters group is a threat actor that emerged in 2023. Security assessments suggest that this group may be derived from the Hive ransomware code. The group's reported announcement in 2025 regarding the cessation of encryption activities suggests that this specific incident may be related to broader shifts in the group's operational strategies.

The implications of this breach are multifaceted. For an organization like Kenworth Del Sur, the encryption of systems can lead to immediate disruptions in operational continuity and significant financial losses. Furthermore, the exfiltration of organizational data may lead to secondary risks, such as the exposure of employee and customer information. Because the organization is based in Mexico, this data breach could result in legal proceedings under local data protection regulations.

In the transportation and logistics sector, maintaining operational uptime is critical. When ransomware attacks disrupt these services, the ripple effects can impact supply chains and service delivery. To mitigate such risks, organizations in this sector typically focus on robust backup strategies, network segmentation to prevent lateral movement by attackers, and continuous monitoring of their digital perimeter. Additionally, ensuring compliance with regional data protection laws is essential for managing the legal risks associated with potential data exposure.
