It’s not the first time we’ve seen an IP camera hacked, and we doubt it will be the last. The overall goal is to find a way to gain complete control over the camera, reprogramming it to serve up video as wishes, rather than to a distant third party server. The work thus is a great example of how to approach hacking a given device from first principles.

uses this to probe around, uncovering the firmware update script and a way to decrypt said updates. For as yet unknown reasons, the camera attempts to resolve Google, Facebook and Alibaba servers over DNS. Disassembly then follows, revealing that a serial terminal with root access is available. The exploration begins externally, with capturing data sent to and from the camera with Wireshark. It’s all a bit oblique, and so decided to take a look under the hood. More often than not, configuration is through a strange smartphone app, and video is accessed through third-party servers. Modern models aimed at the home market differ however. Early models simply presented a video stream and configuration page to the local network. As technology moved forward, IP cameras began to proliferate.

Security cameras used to be analog devices feeding back into a room full of tiny screens and commercial grade VCRs.
