ODRIZ is a custom data-exfiltration tool used by the Earth Kurma cyberespionage group. It uploads collected and archived victim data to Microsoft OneDrive using a supplied OneDrive refresh token, enabling operators to abuse a legitimate cloud-storage service for lower-visibility exfiltration. Earth Kurma has used ODRIZ in intrusions against government and telecommunications organizations in Southeast Asia, alongside document-collection and staging tooling.
