Plz rename this #C to "rogue acs discovery" so we avoid confusion with your #F having a similar tools naming.

If the rootfs is still using squashfs, the timestamp we have here comes from squashfs header metadata, using binwalk over the partition should output that timestamp.

Summary
The exploit uses SRP6a web authentication followed by a signed THENC config import to obtain a root shell. No hardware modification required. The signing key is per-model (not per-device), so it works across all VCNT-9 units.
