RansomHub claims a data breach at D-Caro Solutions

The RansomHub ransomware group has officially listed the Colombian technology firm D-Caro Solutions on its leak site. According to the announcement made on March 8, 2025, the group claims to have successfully exfiltrated a significant amount of data belonging to the organization. The group alleges that the unauthorized access occurred following a cyberattack that took place on February 28, 2025.

This incident follows a pattern often seen in modern ransomware operations, specifically a technique known as double extortion. In these scenarios, threat actors do not merely encrypt an organization's systems to disrupt operations; they also steal sensitive information to use as leverage. By threatening to release stolen data on public leak sites, attackers aim to pressure victims into paying a ransom to prevent the exposure of confidential corporate or client information.

Details of the alleged data exfiltration

The RansomHub group has provided several pieces of evidence to support their claims regarding the breach. The announcement included screenshots that appear to display various internal files and records belonging to the institution. These screenshots specifically highlight file lists from a directory named 'DCLOUD' and various invoice samples. These samples are titled 'Factura - ISiigo' and reportedly contain sensitive details including supplier information and tax-related data.

The group claims that the volume of stolen information is substantial, involving approximately 1.55 TB of data and a total of 1,357,068 files. The specific types of data identified in the leak announcement include:

• Corporate invoice records
• Supplier information
• Operational file directories

While the group has shared these screenshots to validate their claims, the actual contents and the full extent of the data stolen remain subject to the group's assertions.

About D-Caro Solutions

D-Caro Solutions is a technology company based in Colombia. The organization specializes in providing a wide range of technology and telecommunications solutions. Their services are designed to assist various types of enterprises, ranging from small and medium-sized businesses to large-scale corporations, by supporting their organizational and administrative processes through technical expertise.

Analysis and potential implications

The alleged leak of this data carries significant risks for the organization and its business ecosystem. Because the stolen information may include sensitive data regarding commercial operations and supply chain relationships, there is an increased risk of targeted phishing attacks or business fraud directed at the institution's clients and partners. When supplier and invoice details are exposed, attackers can craft highly convincing fraudulent communications to deceive business associates.

Furthermore, as the organization is based in Colombia, this incident could lead to legal consequences under local data protection regulations. Organizations in the technology and telecommunications sector must remain vigilant, as they often handle the critical infrastructure and administrative data of many other businesses.

RansomHub is a group known for its past ties to ALPHV and its operation under a Ransomware-as-a-Service (RaaS) model. Although it was previously reported that RansomHub ceased operations in early 2025, this recent announcement suggests that the impacts of past attacks may persist or that the group's influence remains a factor in the threat landscape.

To defend against such threats, organizations typically implement multi-layered security strategies. This includes maintaining robust, offline backups to ensure data recovery, implementing strict access controls to limit data exposure, and conducting regular security awareness training to help employees recognize phishing attempts. Constant monitoring of network traffic can also help detect unauthorized data exfiltration before it reaches a critical scale.
