| Issue | Risk | Mitigation | |-------|------|------------| | | Unauthorized parties may reuse a key on additional machines. | Store serial numbers in a password‑protected vault (e.g., HashiCorp Vault, Azure Key Vault). Limit read access to SAM admins. | | HWID Spoofing | Attackers could mimic a legitimate machine fingerprint. | Use Nitro’s hardware‑bound token (combines CPU, BIOS, MAC). Periodically audit license.dat for unexpected HWID changes. | | Man‑in‑the‑Middle (MITM) During Activation | Intercepted activation traffic could be altered. | Nitro uses TLS 1.2+ with certificate pinning. Verify the server certificate fingerprint on the client before first activation. | | Expired Activation Tokens | Users lose functionality after 30‑day token expiry if offline. | Implement a scheduled token renewal script (PowerShell or batch) that runs weekly. | | License Audits | Inability to produce proof of license ownership. | Export the activation logs ( %ProgramData%\Nitro\Logs\activation.log ) and retain purchase invoices. |
