IoT search engine ZoomEye dumbs down Dahua DVR hijackings by spewing passwords

Open-source service sticks containers in internet of stuffs

ZoomEye handily indexes not just internet-facing Dahua DVRs by their public IP address, it also fires off the necessary requests to port 37777 to retrieve the devices passwords, and caches it for world-plus-dog to view and use. In other words, it appears to exploit the vulnerability, which is a step further than rival search engines, such as Shodan.io.

Login passwords for tens of thousands of Dahua digital video recorder devices have been cached by ZoomEye, an IoT search engine, and published on the web so that even the dumbest hacker could crack unpatched kit.

The whole sorry affair shows just how easy it has become to exploit IoT devices almost two years after the Mirai IoT botnet rendered many high profile sites inaccessible in an attack some thought might spur a radical shake up. Anubhav favours regulation to impose baseline security standards.

Even though the underlying vulnerability is five years old, simple search queries on ZoomEye are enough to unearth thousands of Dahua DVRs ripe for exploitation. It seems Dahua is happy to sell kit that is insecure, and not help ensure its customers are patched and safe.

As long as an IoT device has a strong password and is updated, it should take care of the bulk of the problem. Zero days will still pop up, but most IoT attackers use known passwords/exploits to hack, and they will fail in their attempts.

Anubhav argued that searching for and exploiting vulnerable Dahua DVR devices has been radically simplified using ZoomEye, which is seemingly based in China. ZoomEyes lead developer for its security team,Heige, has yet to respond directly toEl Regabout whether or not it intends to obfuscate search results that could be useful to script kiddies.

In short, the vulnerability can be exploited like this: connect to a Dahua DVR on TCP port 37777 over the internet, and without any authentication, you can ask it to spit back a binary blob containing the machines serial number, settings, and passwords. With these details, you can remotely log into the devices web-based control panel, and spy on its owner via the recorded camera video, and cause other mischief.

There should be strict regulations for devices to have an update feature, which can be used to automatically push patches to the firmware as soon as the device is connected to the internet, Anubhav toldThe Register.
