Trojan Construction & Holding Group Listed by blacknevas Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Trojan Construction & Holding Group, an Abu Dhabi-based construction firm, has been listed by the ransomware group blacknevas as a victim of a data breach involving the exfiltration of internal files. The listing was reported on October 21, 2025. Public detail remains limited: the number of people affected is unknown, and independent confirmation of the claim has not been established beyond the group's own statements.

According to the group's claims, more than 3 terabytes of project and financial reporting data covering 2024–2025 were taken. The incident matters because organisations of this type routinely handle sensitive commercial, operational and personal information tied to large-scale building projects across the UAE and the wider region.

Breaking down the breach

The available facts centre on a ransomware attack in which internal files were allegedly exfiltrated. blacknevas listed Trojan Construction & Holding Group on its leak site and asserted that over 3 terabytes of project and financial reporting data for 2024–2025 had been obtained. The group also provided a sample link and an email address for parties interested in purchasing the material. No further technical details—such as the initial access method, the precise date of intrusion, encryption of systems, or any ransom demand—have been publicly disclosed. The number of individuals whose data may have been involved remains unknown. All specifics beyond the group's own listing are therefore unconfirmed.

The group behind it: blacknevas

blacknevas is a ransomware operation that follows the well-documented double-extortion model used by many contemporary groups: data is stolen before systems are encrypted, and victims are pressured both by operational disruption and by the threat of public release or sale of the material. The group maintains a leak site on which it posts victim names, sample files and contact details for would-be buyers. Public reporting on blacknevas has described its focus on mid-to-large organisations across multiple sectors, with listings typically accompanied by claims of multi-terabyte exfiltration. In this case the group claims to hold project and financial reporting data belonging to Trojan Construction & Holding Group and invites interested parties to contact Qualitydatarecovery@mail.com. These statements remain unverified claims pending independent corroboration.

Trojan Construction & Holding Group and its sector

Trojan Construction & Holding Group is an Abu Dhabi-based construction company founded in 2012. It operates as a diversified group engaged in high-rise buildings, hospitals, schools, resorts and residential complexes. Public descriptions characterise it as a significant player in the UAE construction sector with a substantial regional project portfolio. Construction and holding companies of this scale typically manage large volumes of contractual, financial, engineering and personnel data, as well as information about clients, subcontractors and public-sector partners. A breach affecting such an organisation can therefore touch commercial confidentiality, project timelines and the personal details of employees and third parties.

What was likely exposed

The facts name the exposed material only as “internal files exfiltrated in a ransomware attack,” with the group further claiming more than 3 terabytes of project and financial reporting data for 2024–2025. Exact contents have not been independently verified. Organisations of this kind commonly hold project plans, cost reports, contracts, invoices, supplier records, employee information and correspondence with clients or regulators. Whether any of those categories were present in the claimed archive is unconfirmed; the public record does not list specific data types beyond the group’s general description of project and financial reporting material.

The real-world impact

For the organisation, the principal risks are commercial: disclosure of project costs, margins or bidding strategies could affect competitive position, while financial reporting data might expose banking relationships or cash-flow details. Operational disruption from any accompanying encryption would compound those concerns. For individuals—employees, contractors or clients—the possible consequences include identity-related fraud, targeted phishing that references real projects, or unwanted contact if personal contact details appear in the files. Because the number of people affected is unknown and the precise contents unconfirmed, the scale of personal impact cannot yet be quantified. The listing itself may also prompt scrutiny from partners and regulators even before any data is released.

What to do if you're exposed

If you have a past or present connection to Trojan Construction & Holding Group—as an employee, contractor, client or supplier—consider the following practical steps:

• Monitor bank and credit accounts for unexpected activity and enable transaction alerts where available.
• Treat unsolicited emails or calls that reference specific projects or internal details with caution; verify independently before responding.
• Change passwords on any accounts that may have used work-related credentials, and enable multi-factor authentication.
• Request a free credit report or fraud alert if you believe financial identifiers could be involved.
• Run a free exposure scan of your email address against known breach data sets to check whether your information has already surfaced elsewhere.

Public detail on this incident remains limited to the blacknevas listing and the claims summarised above. Further official statements from the company or law-enforcement agencies would be required to establish the full scope.
