Desolator claims data breach at Construseñales S.A.

The threat actor group known as Desolator has listed the Colombian manufacturing company Construseñales S.A. on its leak site. According to the announcement made on September 1, 2025, the group claims to be in possession of over 300 GB of data stolen from the organization. The group alleges that they obtained unauthorized access to the company's data on August 28, 2025. Information regarding this specific threat actor group remains limited.

Ransomware attacks often involve a tactic known as double extortion, where attackers not only encrypt a victim's systems to disrupt operations but also exfiltrate sensitive information. By threatening to release this data publicly on a dedicated leak site, the attackers aim to exert maximum pressure on the organization to meet their demands. While the specific ransom demand for this incident has not been disclosed, the threat of public exposure remains a primary motivator for such groups.

Details of the alleged theft

The leak announcement specifies a wide range of sensitive information that has allegedly been exfiltrated from the company. The group claims that the stolen data includes various types of corporate and personal information, which could pose significant risks if released. Specifically, the group claims to have access to the following:

• Company emails
• Customer information
• Business documents
• Personally identifiable information (PII)
• Company databases

Furthermore, the threat actor claims to possess a file containing credentials specifically used for importing PostgreSQL data dumps, which suggests a targeted approach toward the company's database management systems.

About Construseñales S.A.

Construseñales S.A. is a manufacturing company based in Colombia. The organization operates within the manufacturing sector, specializing in the production and sale of traffic signs, road safety equipment, and various related metal products. The company's operations are centered on providing essential infrastructure and safety components for construction and renovation services.

Potential impact and security implications

The alleged exposure of this data carries several significant risks for the organization and its stakeholders. The theft of personally identifiable information (PII) and customer information increases the risk of identity theft and makes employees and customers targets for highly specific, targeted phishing attacks. Such attacks often use stolen business documents or email threads to appear legitimate, thereby increasing the success rate of social engineering attempts.

From a business perspective, the unauthorized access to company databases and business documents could lead to the disclosure of sensitive trade secrets, potentially resulting in a loss of competitive advantage. Additionally, the company may face legal repercussions regarding compliance with Colombian data protection regulations due to the mishandling or loss of sensitive data. The publication of such information can also negatively impact supply chain security and cause significant reputational damage to the organization.

To defend against such threats, organizations in the manufacturing and construction sectors typically implement defensive measures such as robust access controls, multi-factor authentication, and regular security awareness training for employees. Monitoring network traffic for unusual data exfiltration patterns and maintaining offline, immutable backups are also common industry practices to mitigate the impact of ransomware and data theft.
