In LEO, single-event upsets (SEUs) can corrupt stored firmware. Infosat uses:
| Attack Vector | Feasibility | Mitigation in v5.0.3 | |---------------|-------------|------------------------| | Firmware downgrade | Yes | Version monotonic counter (stored in secure element) | | Rollback to vulnerable v4.0 | No | Counter prevents < 5.0.0 | | Glitching bootloader signature check | Theoretical | Bootloader runs from ROM-protected region | | Intercept OTA (man-in-the-middle) | Low (satellite link encrypted) | L2 encryption, but no certificate pinning |

If you can provide the exact device, manufacturer, or context (e.g., “Infosat Model X100”, “Infosat LinkStar”, or “Infosat from [Company Name]”), I will rewrite this paper to match the real firmware version, hardware specs, and known vulnerabilities.
Do not push a new firmware to all devices simultaneously. Use a testing cohort of 3–5 devices. Wait 72 hours before fleet-wide deployment.
Updating Infosat firmware is not like updating a smartphone app. A corrupted update can brick the device. Follow these industry-tested steps:
