Hunters ransomware group claims data breach at Legrand CRM

The Australia-based technology company Legrand CRM has been listed on the leak site of the Hunters International ransomware group. According to an announcement made on June 15, 2024, the group claims that the institution's data was exfiltrated, though the group specifies that the data was not encrypted during the incident.

Ransomware leak sites serve as a platform for cybercriminal groups to pressure victims by threatening to release stolen information. In many modern cyberattacks, threat actors employ a tactic known as double extortion. This method involves not only encrypting a victim's systems to disrupt operations but also stealing sensitive data beforehand. By threatening to publish this information online, the attackers aim to increase their leverage during ransom negotiations, as the threat of a public data leak can cause significant reputational and legal damage even if the company's operational continuity remains intact.

Details of the alleged incident

The Hunters International group posted the claim regarding Legrand CRM on June 15, 2024, which coincides with the date they claim the attack occurred. The group's announcement suggests that the breach involved the unauthorized removal of data from the organization's environment. While the group has confirmed that the data was exfiltrated, they have explicitly stated that the data was not subjected to encryption.

The listing provides specific metrics regarding the scale of the alleged theft, though it does not provide specific details regarding the content of the allegedly leaked data. The information provided by the group is limited to the following statistics:

• Total data size: 157.1 GB
• Total file count: 117,315 files

No specific details regarding the content of the allegedly leaked data have been provided; the available information is limited to the total data size and the file count shown in the group's screenshot.

About the threat actor

Hunters International is a ransomware group that emerged in 2023. The group is assessed to be derived from the Hive ransomware code. Reports indicate that the group ceased its encryption activities in 2025. The nature of this specific incident, where data is stolen without encryption, suggests that the institution's data may have been compromised through these double extortion methods commonly used by such groups.

Potential consequences and defensive considerations

The implications of such a breach can be multifaceted. Under the Australian Privacy Act, the institution may face mandatory data breach notification requirements, which could lead to legal sanctions. Depending on the actual content of the leaked data, there is a potential risk that employees or customers might be targeted by identity theft and targeted phishing attacks.

While the incident may not have a direct impact on the institution's operational continuity, a data breach of this scale can result in negative consequences for corporate reputation. In the technology sector, maintaining trust is paramount, and the public disclosure of a breach can damage client relationships.

To mitigate the risks associated with data exfiltration, organizations typically focus on several defensive layers. Implementing robust data loss prevention (DLP) tools can help detect and block unauthorized transfers of sensitive information. Furthermore, monitoring network traffic for unusual outbound data flows can provide early warnings of exfiltration attempts. Organizations should also prioritize strict access controls and the principle of least privilege to ensure that even if a perimeter is breached, the amount of data accessible to an attacker is minimized. Regular security audits and adherence to regional privacy regulations are essential for maintaining compliance and managing the legal risks associated with data breaches.
