Siena Construction

Siena Construction was compromised in a ransomware attack attributed to NIGHTSPIRE in March 2026. The organization, operating in the Construction sector in United States, was added to the group's data leak site as part of an extortion campaign.

NIGHTSPIRE 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.
