An anonymous reader quotes a report from Fast Company: Forget your classic listening device: Researchers at the University of Washington have demonstrated that phones, smart TVs, Amazon Echo-like assistants, and other devices equipped with speakers and microphones could be used by hackers as clandestine sonar "bugs" capable of tracking your location in a room. Their system, called CovertBand, emits high-pitched sonar signals hidden within popular songs -- their examples include songs by Michael Jackson and Justin Timberlake -- then records them with the machine's microphone to detect people's activities. Jumping, walking, and "supine pelvic tilts" all produce distinguishable patterns, they say in a paper. (Of course, someone who hacked the microphone on a smart TV or computer could likely listen to its users, as well.)

On Thursday, Hyundai Motor said it will launch a long-range electric vehicle with a driving range of 500 km (311 miles) per charge after 2021. The company is reportedly planning 31 eco-friendly models by 2020, up from a previously flagged 28. Reuters reports: The South Korean automaker is planning to launch an electric sedan under its high-end Genesis brand in 2021 with a range of 500 km (310 miles) per charge. It will also introduce an electric version of its Kona small sport utility vehicle (SUV) with a range of 390 km in the first half of next year. The automaker and affiliate Kia Motors Corp, which together rank fifth in global vehicle sales, also said they were adding three plug-in vehicles to their plans for eco-friendly cars, bringing the total to 31 models by 2020. Underscoring Hyundai's electric shift, those plans include eight battery-powered and two fuel-cell vehicles -- a contrast to its 2014 announcement for 22 models, of which only two were slated to be battery-powered. Hyundai also confirmed a Reuters report that it is developing its first dedicated electric vehicle platform, which will allow the company to produce multiple models with longer driving ranges.

An anonymous reader shares Dieter Bohn's review of the Essential Phone: Even though it was announced less than three months ago at the Code Conference, there's already enough mythology surrounding the Essential Phone to fill a book. It comes from a brand-new billion-dollar startup led by the person who helped create Android itself, Andy Rubin. That origin binds it up with the history of all smartphones in a way that doesn't usually apply to your run-of-the-mill device. The phone was also delayed a bit, a sign that this tiny company hasn't yet quite figured out how to punch above its weight class -- which it's certainly trying to do. Although it runs standard Android, it's meant to act as a vanguard for Essential's new ecosystem of smart home devices and services connected by the mysterious Ambient OS. Even if we trust that Rubin's futuristic vision for a connected home will come to pass, it's not going to happen overnight. Instead, all we really have right now is that future's harbinger, a well-designed Android phone that I've been testing for the past week. Available unlocked or at Sprint, the $699 Essential Phone is an ambitious device. It has a unique way to connect modular accessories, starting with a 360-degree camera. It has a bold take on how to make a big, edge-to-edge screen paired with top-flight materials such as ceramic and titanium. And it has a dual camera system that is meant to compete with other flagship devices without adding any thickness to the phone. That would be a lot for even a massive company like Samsung or Apple to try to do with a single phone. For a tiny company like Essential, the question is simply this: is it trying to do too much? In conclusion, Bohn writes: "The Essential Phone is doing so much right: elegant design, big screen, long battery life, and clean software. And on top of all that, it has ambitions to do even more with those modules. If you asked Android users what they wanted in the abstract, I suspect a great many of them would describe this exact device. But while the camera is pretty good, it doesn't live up to the high bar the rest of the phone market has set. Sometimes artifacts are better to behold than they are to use."

Dan Goodin, writing for ArsTechnica: People with cracked touch screens or similar smartphone maladies have a new headache to consider: the possibility the replacement parts installed by repair shops contain secret hardware that completely hijacks the security of the device. The concern arises from research that shows how replacement screens -- one put into a Huawei Nexus 6P and the other into an LG G Pad 7.0 -- can be used to surreptitiously log keyboard input and patterns, install malicious apps, and take pictures and e-mail them to the attacker. The booby-trapped screens also exploited operating system vulnerabilities that bypassed key security protections built into the phones. The malicious parts cost less than $10 and could easily be mass-produced. Most chilling of all, to most people, the booby-trapped parts could be indistinguishable from legitimate ones, a trait that could leave many service technicians unaware of the maliciousness. There would be no sign of tampering unless someone with a background in hardware disassembled the repaired phone and inspected it. The research, in a paper presented this week (PDF) at the 2017 Usenix Workshop on Offensive Technologies, highlights an often overlooked disparity in smartphone security. The software drivers included in both the iOS and Android operating systems are closely guarded by the device manufacturers, and therefore exist within a "trust boundary."

A new feature baked into iOS 11 lets you quickly disable Touch ID, which could come in handy if you're ever in a situation where someone (a cop) might force you to unlock your device. Cult of Mac reports: To temporarily disable Touch ID, you simply press the power button quickly five times. This presents you with the "Emergency SOS" option, which you can swipe to call the emergency services. It also prevents your iPhone from being unlocked without the passcode. Until now, there were other ways to temporarily disable Touch ID, but they weren't quick and simply. You either had to restart your iPhone, let it sit idle for a few days until Touch ID was temporarily disabled by itself, or scan the wrong finger several times. The police, or any government agency, cannot force you to hand over your iPhone's passcode. However, they can force you to unlock your device with your fingerprint. That doesn't work if your fingerprint scanner has been disabled.
