Company in Construction

Company in Construction was compromised in a ransomware attack attributed to elf.qilin in March 2026. The organization, operating in the Construction sector in Argentina, was added to the group's data leak site as part of an extortion campaign.

elf.qilin 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.
