Osiris is a ransomware-as-a-service operation first observed in November 2025 that uses a Bring Your Own Vulnerable Driver (BYOVD) technique to disable endpoint detection tools before deploying hybrid ECC + AES-128-CTR encryption; Symantec researchers linked its operators to former INC ransomware affiliates.
