Rasen Insaat Ve Yatirim Ticaret A.S. was compromised in a ransomware attack attributed to blackshrantac in November 2025. The organization, operating in the Construction sector in TR, was added to the group's data leak site as part of an extortion campaign.

blackshrantac 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.
