Lutha Mahtin posted:do you really think it is likely that all those devices will use different chips and totally unique custom software stacks? even across different manufacturers i would (again) bet money that we are going to see the exact same poo poo we've been seeing for years now in consumer routers and iot crap: they will all use cheapo misconfigured software stacks full of old non-updated FOSS stuff written in unsafe languages like C. "oh but the protocol is pretty limited"! sure that's great but even if it's very locked down, it will mean jack if these devices have any alternate communication modes, or if other devices (like laptops or iot crap) have the ability to talk to the appliances via that protocol, because then all it will take is someone to discover a flaw in the 7-year-old version of linux that all these things are running, or a misconfiguration that exists across the software stacks of the 3 most popular smart-grid middleware providers. and on that point, i have a hard time believing that appliance makers can resist the temptation to add in features like "manage your kenmore appliances from ANYWHERE IN THE WORLD with the kenmore app!" and bolting on some kind of wi-fi interface which is of course then managed by the same main CPU/SoC that also does the locked-down smart-grid protocol stuff zigbee devices and wifi internet of things devices are in very different worlds. a "powerful" edge device is running on something like a cortex m4, a m0 or an 8bit micro will be more typical. these edge devices will communicate with the power company's routers which hopefully has a backhaul over an air gapped network. those routers would certainly be vulnerable, but the edge devices don't seem like they'd be a very good target.

Also, from the article:quote:Rawls was thrown in the slammer on September 30, 2015 "until such time that he fully complies" (PDF) with a court order to unlock his hard drives. A child-porn investigation focused on Rawls when prosecutors were monitoring the online network, Freenet. They executed a search warrant in 2015 at Rawls' home. The authorities say it's a "foregone conclusion" that illicit porn is on those drives. But they cannot know for sure unless Rawls hands them the alleged evidence that is encrypted with Apple's standard FileVault software. then do you loving job and put it in front of a jury

the only problem is...quote:mbed TLS (formerly known as PolarSSL) makes it trivially easy for developers to include cryptographic and SSL/TLS capabilities in their (embedded) products, facilitating this functionality with a minimal coding footprint. sounds like a challenge. someone is going to push keys of straight 0s into production

Even if you install apps from alternate stores (f-droid, etc), drat near everything expects the play framework to be present and will just crash when the api calls fail.
