How About Privacy and Hackability?

3 Agosto 2024 at 14:00

Many smart electric meters in the US use the 900 MHz band to broadcast their usage out to meter readers as they walk the neighborhood. [Jeff Sandberg] used an RTL-SDR dongle and some software to integrate this data into his own home automation system, which lets him keep track of his home’s power usage.

Half of the comment section was appalled that the meters broadcast this data in the clear, and these readers thought this data should be encrypted even if the reach is limited to the home-owner’s front yard. But that would have stopped [Jeff] from accessing his own data as well, and that would be a shame. So there’s clearly a tradeoff in play here.

We see this tradeoff in a lot of hardware devices as well – we want to be able to run our firmware on them, but we don’t want criminals to do the same. We want the smart device to work with the cloud service, but to also work with our own home automation system if we have one. And we want to be able to listen in to our smart meters, but don’t necessarily want others to do so.

The solution here is as easy as it is implausible that it will get implemented. If the smart meters transmitted encrypted, each with their own individual password, then everyone would win. The meter reader would have a database of passwords linked to meter serial numbers or addresses, and the home owner could just read it off of a sticker, optimally placed on each unit. Privacy and usability would be preserved.

This issue isn’t just limited to electric meters. Indeed, think of all of the data that is being sent out from or about you, and what percentage of it is not encrypted and should be, but also about what data is sent out encrypted that you could use access to. The solution is to put you in control of the encryption, by selecting a password or having access to one that’s set for you. Because after all, if it’s your data, it should be your data: private and usable.

Ask Hackaday: Has Firefox Finally Gone Too Far?

In a world where so much of our lives depend on the use of online services, the web browser used to access those services becomes of crucial importance. It becomes a question of whether we trust the huge corporate interests which control this software with such access to our daily lives, and it is vital that the browser world remains a playing field with many players in the game.

The mantle has traditionally fallen upon Mozilla’s Firefox browser to represent freedom from corporate ownership, but over the last couple of years even they have edged away from their open source ethos and morphed into an advertising company that happens to have a browser. We’re asking you: can we still trust Mozilla’s Firefox, when the latest version turns on ad measurement by default?

Such has been the dominance of Google’s Chromium in the browser world, that it becomes difficult to find alternatives which aren’t based on it. We can see the attraction for developers, instead of pursuing the extremely hard task of developing a new browser engine, just use one off-the-shelf upon which someone else has already done the work. As a result, once you have discounted browsers such as the venerable Netsurf or Dillo which are cool as heck but relatively useless for modern websites, the choices quickly descend into the esoteric. There are Ladybird and Servo which are both promising but still too rough around the edges for everyday use, so what’s left? Probably LibreWolf represents the best option, a version of Firefox with a focus on privacy and security.

We’re interested in your views on this topic, because we know you’ll have a lot to say about it. Meanwhile if you’re a Firefox user who’s upgraded to version 128 and you’re not sure what to do, don’t panic. Find the settings page, go to “Privacy and Security”, and un-check the “Website Advertising Preferences” checkbox.
