80+ OEMs Verified Vulnerable To Hikvision Backdoor

Author: Brian Karas, Published on Sep 22, 2017

Over 80 Hikvision OEM partners, including ADI, Interlogix, LTS, and Northern Video, have been verified as having products vulnerable to the Hikvision backdoor, deployed and exploitable over the public Internet.

IPVM ran tests to verify this using public data and the signature of the backdoor. Our test results found ~40% of all vulnerable devices were from OEMs, with the balance 60% being Hikvision own's branded products. In total, we estimate at least 250,000 devices vulnerable on the public Internet.

This vulnerability is particularly severe because it is simple to exploit and allows attackers to take over the camera by changing the admin password, view images, default the device, brick it, etc.

Demo

Our video below shows how even non-technical users can literally just copy/paste the backdoor string on to the end of a URL to vulnerable Hikvision and OEM partner cameras:
