Balfour Beatty

Balfour Beatty was compromised in a ransomware attack attributed to coinbasecartel in April 2026. The organization, operating in the Construction sector in United Kingdom, was added to the group's data leak site as part of an extortion campaign.

coinbasecartel operates as a financially motivated ransomware-as-a-service (RaaS) operation, exfiltrating sensitive data and threatening public disclosure to pressure victims into paying ransom demands.
