Hunters ransomware group lists data allegedly belonging to HB Construction

The threat actor known as Hunters International has listed data allegedly belonging to HB Construction on its leak site. The group claims to have successfully targeted the organization, marking a new incident involving the group's operations. This announcement, made on September 13, 2024, suggests a significant breach of the company's digital infrastructure.

Details of the claimed attack

According to the claims made by the Hunters International group, the attackers have infiltrated the systems of HB Construction. The group alleges that they have not only gained access to the network but have also encrypted the organization's data. This tactic is a hallmark of modern ransomware operations, where attackers use encryption to disrupt business operations and demand payment for the decryption keys.

The threat actor has published a listing on their public leak portal, which serves as a platform for demonstrating the success of their intrusion. By listing the victim's information publicly, the group aims to exert pressure on the organization. In such scenarios, the presence of a leak site often indicates a double extortion strategy, where data is both encrypted to halt operations and exfiltrated to be used as leverage for ransom demands.

Scope of the alleged data breach

The information provided by the threat actor regarding the stolen data is limited to specific metrics. While the group has provided quantitative details about the breach, they have not specified the exact nature or the types of files that were compromised. The listing provides the following details regarding the alleged theft:

• Total data size: 505.2 GB
• Total file count: 160,734 files

Beyond these specific figures, there is no information regarding the specific content or the nature of the exfiltrated data. The provided screenshots or evidence only indicate the total volume and the number of files involved in the incident.

About HB Construction

HB Construction is a construction and contracting firm based in the United States. The company operates in the field of various building projects and construction services, providing essential infrastructure and development solutions within its operating region.

Analysis and potential impact

This incident may pose a significant risk to the organization's operational continuity. Given that the entity is based in the United States, state-level data protection regulations and potential legal notification requirements could be applicable. The exposure of data may lead to secondary risks such as identity theft or targeted phishing attacks against employees and business partners.

Hunters International is known as a group that emerged in 2023 and is believed to be derived from the Hive codebase. Their previous announcements regarding the cessation of encryption activities in 2025 may indicate a shift in their operational strategy, making their current activities a point of interest for threat intelligence analysts. When organizations face such breaches, it is often advisable to initiate a comprehensive forensic investigation to determine the full scope of the compromised data and to identify the initial entry point used by the attackers.

For organizations in the professional services and construction sectors, maintaining robust cybersecurity postures is critical. This includes implementing multi-factor authentication, maintaining offline backups, and conducting regular security awareness training to mitigate the risk of phishing, which is a common vector for ransomware deployment. As seen in this case, the volume of data involved can be substantial, making rapid detection and response essential to minimize the impact on business operations and regulatory compliance.
