They don't say whether they actually caught the DVR in the act of e-mailing frames. A simple Wireshark trace could reveal the difference between malintent and some dumb vestigial debugging code.
Actually, from a brief scan of a related codebase, it's likely that it doesn't send e-mails. The title of the article is therefore at a minimum unsubstantiated.
- cybergibbons 11y agoI'm the author. My device sends an email at boot to the email address, and it has also been triggered at other times - I am not sure why. It looks like there are a number of variants of the device out there. The repo mentioned in another comment has a MakeFile for another device, and has been forked 9 times. It could be used anywhere. The article will be updated, but I'll have to get a trace another time.
- cybergibbons 11y agoSomeone else who has looked at them has pointed out that theirs reboots randomly. I haven't actually been using the DVR functionality, so I suspect that the emails are only sent at boot and it boots more often than I expected.
