This is a continuation from here.
Here is the complete script that can reset any given Hikvision camera with firmware of up to 5.3 (allegedly).
The security through obscurity aspect of it, and inability to reset the camera without contacting the Hikvision support under normal circumstances puts me off the Hikvision hardware entirely.
There is an obvious problem with contacting Hikvision support, no way they will provide support for cameras bought from Aliexpress. Since password reset is not under owner’s control, it means that owner does not technically own the camera.
This script will discover the Hikvision cameras (both via UDP and magical frame 0x8033) on local L2. You can also specify to reset a camera with a specific MAC address (although it is not too difficult to modify it to own all the cameras, but I purposely left that bit out).
The script is a bit crude and inefficient (too many byte to ASCII conversions).
TL;DR: do not buy Hikvision cameras as the official password recovery involves Hikvision support, while “hackers” can own your camera once they get L2 access to your network.
