RansomHub claims a data breach against internetway.com.br

The ransomware group known as RansomHub has listed the Brazilian technology company internetway.com.br on its dedicated leak site. This announcement, which surfaced on December 3, 2024, involves an allegation of a significant data breach against the organization. Ransomware groups often utilize these leak sites as a method of double extortion, where they not only encrypt an organization's systems but also threaten to publish sensitive information to pressure the victim into paying a ransom.

According to the claims made by the threat actor, the breach occurred much earlier than the public announcement. The group cites October 21, 2024, as the date the alleged attack took place. RansomHub asserts that they successfully gained unauthorized access to the internal network of internetway.com.br. By penetrating the network, the group claims to have exfiltrated sensitive information from the organization's infrastructure.

Details regarding the alleged stolen data

While the threat actor has officially listed the organization on their platform, specific details regarding the content of the breach remain unavailable. There is no information provided regarding the nature of the leaked or compromised data, nor has there been any mention of the total volume of files or the specific size of the exfiltrated datasets. Furthermore, no ransom demand has been publicly specified in relation to this particular listing.

The listing names no specific data types or categories of information that were allegedly compromised. During the observation of the leak site, technical difficulties were noted, as the platform was experiencing a technical gateway error at the time of capture, which may have further limited the visibility of any posted evidence.

About internetway.com.br

The organization plays a significant role in the regional technology sector by providing various digital services.

Risk assessment and organizational implications

This incident may pose significant risks to the organization's operational continuity and data confidentiality. Given the history of the RansomHub group, it is possible that the allegedly exfiltrated data could be utilized in secondary attacks or identity theft activities. Such secondary exploitation is a common tactic in modern cybercrime, where stolen credentials or corporate data are sold on illicit forums or used to launch further targeted campaigns against the same or related entities.

Because the organization is based in Brazil, the incident may trigger legal proceedings under the local data protection law, LGPD. Compliance with such regulations is a critical aspect of managing a data breach in the modern regulatory landscape. Additionally, reports suggesting that the RansomHub group ceased operations in early 2025 may create uncertainty regarding the actual status and availability of the data claimed to be stolen.

For organizations operating in the technology and service provider sectors, maintaining robust security postures is essential. This typically involves implementing multi-factor authentication, maintaining strict network segmentation to prevent lateral movement by attackers, and conducting regular security audits. In the event of a suspected breach, it is advisable for the organization to conduct a comprehensive forensic investigation to verify the extent of any potential data breach and to ensure that all unauthorized access points have been identified and remediated.
