What can be more concerning for today’s generations than global warming? Yes, the security of IoT devices! Fortunately, you can use one problem to mitigate the other: if you complain at CHAL-TEC about backdoor accounts in their products, apparently they’ll send you a ceiling fan (firmware update not included): “I bought an Auna Connect 100 iot radio device in august 2018 on Electronic Star’s Amazon market (Auna and Electronic Star are both entities of CHAL-TEC GmbH). 30 days ago I asked them if there is a fix to their nearly one year old undocumented telnet backdoor problem (CVE-2019-13473 and CVE-2019-13474) and/or to reimburse me.This is what I received yesterday: “Je vous conseille de vous renseigner auprès de vos proches, voisins et/ou concierge. En effet, quelqu’un aurait pu réceptionner le colis pour vous en votre absence.” It means: I advise you to inquire with your relatives, neighbors and / or concierge. Indeed, someone could have received the package for you in your absence.
