What Public Reporting Shows
Public reporting indicates the company was listed on the DragonForce leak portal hosted on an onion domain. The posting states that internal files were taken during a ransomware incident. At the time of publication, the exact number of people whose information appears in the files remains unknown. Available reporting describes the exposed material as internal documents rather than a structured database of customer records, though such files frequently contain employee details, supplier contacts, project information, and correspondence that can be repurposed.
May 27, 2026 marks the public listing date. The breach type is a classic ransomware attack combining encryption with data theft for extortion. No confirmed victim count has been released by ERH or the attackers.
Why This Matters for You and Your Family
When a company that handles infrastructure projects across the UK suffers a breach, the ripple effects reach ordinary people. If you or your family members have ever worked with traffic management firms, used their services indirectly through local councils, or had your personal details stored in supplier or employment records, those details may now sit in files controlled by criminals. Even a single leaked email, phone number, or address becomes raw material for identity thieves who combine it with other scraps of information already circulating online.
