• Announcement date: February 10, 2026

Agis Civil Engineering Construction, a prominent engineering group based in Brazil, has been listed on the leak site operated by the threat group known as thegentlemen. This listing, which appeared on the platform on February 10, 2026, serves as an assertion by the group that the organization's data may have been compromised.

The claim by thegentlemen

The threat group thegentlemen published an announcement by listing Agis Civil Engineering Construction on their dedicated leak site. This action is a common tactic used by ransomware actors to pressure victims. In such scenarios, the group claims to have successfully infiltrated a network and exfiltrated sensitive information. By publishing the name of the target on a public-facing platform, the group attempts to validate their intrusion and increase the visibility of the incident.

Ransomware leak sites function as a public gallery for cybercriminals. These platforms are often used in double extortion schemes, where attackers not only encrypt an organization's systems but also threaten to release stolen data to the public if a ransom is not paid. This method aims to maximize the pressure on the victim by threatening their reputation and legal standing. In this specific instance, the listing appeared on February 10, 2026, marking the official announcement of the alleged breach by the threat group.

Details regarding the alleged data breach

At this time, there is no information available regarding the nature or content of the allegedly compromised data. The listing does not specify the types of files, the volume of data, or the specific systems that were targeted. Furthermore, there is no information available regarding the ransom demand or the total file count involved in this incident.

Attempts to verify the claim by accessing the group's leak site encountered a verification timeout error. Consequently, the specific details of the alleged exfiltration remain unconfirmed. The listing names no specific data types.

Organizational profile

Grupo Agis is a Brazilian engineering group operating in construction, integrated energy solutions, and mining. The company specializes in various public and private sector projects, including metro, road, port, and water infrastructure.

Potential risks and recommended actions

This incident may pose operational and reputational risks for Agis Civil Engineering Construction. Because the organization operates within Brazil, the entity may face data breach notification obligations under the LGPD (General Data Protection Law). Compliance with such regulations is a critical aspect of managing cyber incidents in the region, as failure to report breaches can lead to significant regulatory scrutiny.

Depending on the nature of the exposed data, the disclosure of personal information of employees or clients could lead to secondary risks such as identity theft. When sensitive personal data is leaked, the impact extends beyond the initial breach, potentially affecting the privacy and security of individuals associated with the company for an extended period.

Publicly available information regarding the specific activities and methods of the group known as thegentlemen is limited. For organizations facing similar threats, it is generally advisable to initiate a comprehensive forensic investigation to determine the scope of the intrusion and assess potential data exposure. Defensive measures typically include enhancing network monitoring, implementing strict access controls, and ensuring robust backup protocols are in place to mitigate the impact of such attacks. In this case, the organization would need to evaluate its systems to confirm whether any actual data exfiltration occurred following the group's claim.
