Vexday analysis
BlackByte (também identificado como Hecamede, G1043 no MITRE ATT&CK) é um agente de ameaça de ransomware ativo desde pelo menos 2021, associado a múltiplas versões do malware homônimo. As versões iniciais do ransomware utilizavam uma chave de criptografia comum, o que permitiu o desenvolvimento de um decryptor universal; versões posteriores, como o BlackByte 2.0, adotaram mecanismos de criptografia mais robustos. O grupo é notável por operações direcionadas a entidades de infraestrutura crítica, entre outros alvos na América do Norte, e possui 48 técnicas documentadas no MITRE ATT&CK, 3 CVEs atribuídas e 4 vítimas conhecidas no Brasil.
