Incident analysis

Trojan Construction & Holding Group was listed by Blacknevas ransomware, a group with 50 victims recorded in this database. The listing appeared on the group's leak site on October 27, 2025.

Trojan Construction & Holding Group is based in UAE and operates in the Construction sector. UAE ranks #19 worldwide for ransomware disclosures, with 173 victims in this database.

Sector context. Construction firms often hold sensitive project data, client financials, and intellectual property. The industry's typically lean IT security teams can make them more vulnerable.

Blacknevas typically follows a double extortion model: data is exfiltrated from the victim's systems before files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished. The leak site, where this listing appeared, is the lever for the second demand.

Source. Public leak-site disclosures aggregated via the ransomware.live API. The disclosure date is when the listing was published, which can differ from the date of compromise. This site does not publish or link to stolen data. Last updated .
