Hunters ransomware group claims breach of Sunrise Erectors

The ransomware group known as Hunters International has listed the United States-based organization Sunrise Erectors on its leak site. According to the group's announcement, the organization has been targeted in a cyberattack involving both data exfiltration and encryption. The threat actor claims to have gained unauthorized access to the organization's network, leading to a significant data breach.

Details of the alleged attack

The announcement made by Hunters International on September 4, 2024, alleges that the organization's data has been both exfiltrated and encrypted. The group claims to have successfully compromised a massive volume of information during the intrusion. While the specific methods used to gain access were not detailed, the group asserts that they have successfully infiltrated the network of Sunrise Erectors.

Ransomware attacks often involve a strategy known as double extortion. In these scenarios, threat actors do not merely encrypt a victim's files to disrupt operations; they also steal sensitive information. This allows the attackers to threaten the public release of the stolen data if the ransom is not paid, creating additional pressure on the victim. This tactic aims to maximize the leverage held by the attacker, as the threat of a data leak can cause significant reputational and legal damage even if the organization can restore its systems from backups.

Data involved in the claim

The threat actor has provided specific metrics regarding the scale of the alleged theft. According to the group's claims, the breach involves a substantial amount of information, including the following details:

• A total data size of approximately 1 TB
• A file count consisting of 500,904 files

The specific nature of the exfiltrated data has not been disclosed by the group. However, it is assessed that the 1 TB dataset may contain various corporate documents and operational files essential to the company's business functions.

About Sunrise Erectors

Sunrise Erectors is a company based in the United States that specializes in steel erection and construction services. The organization provides structural steel installation and various related construction solutions designed for both commercial and industrial projects.

Risk assessment and industry implications

Hunters International is a ransomware group that emerged in 2023. It is assessed to be derived from the Hive codebase. It has been reported that the group announced the cessation of its encryption activities in 2025. The exfiltration of an organization's data can lead to various secondary risks, such as the exposure of sensitive employee and client information.

Because Sunrise Erectors is a US-based entity, any potential data breach may fall under the scope of state-level data protection laws and regulations. Such incidents can lead to significant operational disruptions and long-term reputational damage for the organization. Furthermore, the leaked data could potentially be leveraged by threat actors for future targeted phishing attacks, where attackers use stolen information to craft highly convincing fraudulent communications.

For organizations operating in the professional services and construction sectors, maintaining robust cybersecurity postures is essential. This typically involves implementing multi-factor authentication, maintaining regular offline backups, and conducting regular network monitoring to detect unauthorized access. As attackers continue to evolve, the risk of data exfiltration remains a primary concern for businesses managing large volumes of corporate and client documentation.
