Sea Telecom Br

Sea Telecom Br was compromised in a ransomware attack attributed to coinbasecartel in April 2026. The organization, operating in the Telecommunications sector in Brazil, 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.
