Backdoor In MVPower DVR Firmware Sends CCTV Stills To an Email Address In China (softpedia.com)

Posted by timothy on from the candid-camera dept.

An anonymous reader writes: An IoT security research company has discovered that a DVR model manufactured by MVPower includes a backdoor-like feature in its code that takes a screenshot of your CCTV feed and sends it to an email address hosted somewhere in China. The device's firmware is based on an open source project from GitHub that was pulled by its developer when someone confronted him about the backdoor.

      The problem is nearly everything, even that from big name American companies, is manufactured in China. When looking for baby monitors some of the no-name Chinese brands were cheaper or had features I would have liked but I avoided them because I was afraid of security/privacy issues. I went with a Motorola, but in the end even it is going to be made in China, so who's to say it doesn't have a hardware backdoor as well, and all the data breaches in the news show that even big American companies seem to not care about security either.

      You can't avoid it. I guess you just look for the ones that suck the least, like voting.... sigh.
