Apple’s Sidecar just really *gets* me, you know? – TechCrunch

Published

on

With the rollout of Apple’s public beta software previews of macOS and the new iPadOS, I’ve finally been able to experience first-hand Sidecar, the feature that lets you use an iPad as an external display for your Mac. This is something I’ve been looking to make work since the day the iPad was released, and it’s finally here – and just about everything you could ask for.

These are beta software products, and I’ve definitely encountered a few bugs including my main Mac display blanking out and requiring a restart (that’s totally fine – betas by definition aren’t fully baked). But Sidecar is already a game-changer, and one that I will probably have a hard time living without in future – especially on the road.

Falling nicely into the ‘it just works’ Apple ethos, setting up Sidecar is incredibly simple. As long as your Mac is running macOS 10.15 Catalina, and your iPad is nearby, with Bluetooth and Wifi enabled, and running the iPadOS 13 beta, you just click on the AirPlay icon in your Mac’s Menu bar and it should show up as a display option.

Once you select your iPad, Sidecar just quickly displays an extended desktop from your Mac on the iOS device. It’s treated as a true external display in macOS System Preferences, so you can arrange it with other displays, mirror your Mac and more. The one thing you can’t do that you can do with traditional displays is change the resolution – Apple keeps things default here at 1366 x 1024, but it’s your iPad’s extremely useful native resolution (2732 x 2048, plus Retina pixel doubling for the first-generation 12.9-inch iPad Pro I’m using for testing), and it means there’s nothing weird going on with pixelated graphics or funky text.

Apple also turns on, by default, both a virtual Touchbar and a new feature called ‘Sidebar’ (yes, it’s a Sidebar for your Sidecar) that provides a number of useful commands including the ability to call up the dock, summon a virtual keyboard, quickly access the command key and more. This is particularly useful if you’re using the iPad on its own without the attached Mac, which can really come in handy when you’re deep in a drawing application and just looking to do quick things like undo, and Apple has a dedicated button in Sidebar for that, too.

The Touchbar is identical to Apple’s hardware Touchbar, which it includes on MacBook Pros, dating back to its introduction in 2016. The Touchbar has always been kind of a ‘meh’ feature, and some critics vocally prefer the entry-level 13-inch MacBook Pro model that does away with it altogether in favor of an actual hardware Escape key. And on the iPad using Sidecar, you also don’t get what might be its best feature – TouchID. But, if you’re using Sidecar specifically for photo or video editing, it’s amazing to be able to have it called up and sitting there ready to do, as an app-specific dedicated quick action toolbar.

Best of all, Apple made it possible to easily turn off both these features, and to do so quickly right from your Mac’s menu bar. That way, you get the full benefit of your big beautiful iPad display. Sidecar will remember this preference too for next time you connect.

Also new to macOS Catalina is a hover-over menu for the default window controls (those three ‘stoplight’ circular buttons that appear at the top left of any Mac app). Apple now provides options to either go fullscreen, tile your app left or right to take up 50% of your display, or, if you’re using Sidecar, to quickly move the app to Sidecar display or back.

This quick shuffle action works great, and also respects your existing windows settings, so you can move an app window that you’ve resized manually to take up a quarter of your Mac’s display, and then when you send it back from the Sidecar iPad, it’ll return to where you had it originally in the same size and position. It’s definitely a nice step up in terms of native support for managing windows across multiple displays.

I’ve been using Sidecar wirelessly, though it also works wired and Apple has said there shouldn’t really be any performance disparity regardless of which way you go. So far, the wireless mode has exceeded all expectations, and any third-party competitors in terms of reliability and quality. It also works with the iPad Pro keyboard case, which makes for a fantastic input alternative if you happen to be closer to that one instead of the keyboard you’re using with your Mac.

Sidecar also really shines for digital artists, because it supports input via Apple Pencil immediately in apps that have already built in support for stylus input on Macs, including Adobe Photoshop and Affinity Photo. I’ve previously used a Wacom Cintiq 13HD with my Mac for this kind of thing, and I found Apple’s Sidecar to be an amazing alternative, not least of which because it’s wireless and even the 12.9 iPad Pro is such more portable than the Wacom device. Input seems to have very little response lag (like, it’s not even really perceivable), there’s no calibration required to make sure the Pencil lines up with the cursor on the screen, and as I mentioned above, combined with the Sidebar and dedicated ‘Undo’ button, it’s an artistic productivity machine.

The Pencil is the only means of touch input available with Sidecar, and that’s potentially going to be weird for users of other third-party display extender apps, most of which support full touch input for the extended Mac display they provide. Apple has intentionally left out finger-based touch input, because Mac just wasn’t designed for it, and in use that actually tracks with what my brain expects, so it probably won’t be too disorienting for most users.

When Apple introduced the 5K iMac, it left out one thing that had long been a mainstay of that all-in-on desktop – Target Display Mode. It was a sad day for people who like to maximize the life of their older devices. But they’ve more than made up for it with the introduction of Sidecar, which genuinely doubles the utility value of any modern iPad, provided you’re someone for whom additional screen real estate, with or without pressure-sensitive pen input, is something valuable. As someone who often works on the road and out of the office, Sidecar seems like something I personally designed in the room with Apple’s engineering team.

Hard-coded key vulnerability in Logix PLCs has severity score of 10 out of 10

Published

on

Rockwell Automation

Hardware that is widely used to control equipment in factories and other industrial settings can be remotely commandeered by exploiting a newly disclosed vulnerability that has a severity score of 10 out of 10.

The vulnerability is found in programmable logic controllers from Rockwell Automation that are marketed under the Logix brand. These devices, which range from the size of a small toaster to a large bread box or even bigger, help control equipment and processes on assembly lines and in other manufacturing environments. Engineers program the PLCs using Rockwell software called Studio 5000 Logix Designer.

On Thursday, the US Cybersecurity & Infrastructure Security Administration warned of a critical vulnerability that could allow hackers to remotely connect to Logix controllers and from there alter their configuration or application code. The vulnerability requires a low skill level to be exploited, CISA said.

The vulnerability, which is tracked as CVE-2021-22681, is the result of the Studio 5000 Logix Designer software making it possible for hackers to extract a secret encryption key. This key is hard-coded into both Logix controllers and engineering stations and verifies communication between the two devices. A hacker who obtained the key could then mimic an engineering workstation and manipulate PLC code or configurations that directly impact a manufacturing process.

“Any affected Rockwell Logix controller that is exposed on the Internet is potentially vulnerable and exploitable,” said Sharon Brizinov, principal vulnerability researcher at Claroty, one of three organizations Rockwell credited with independently discovering the flaw. “To successfully exploit this vulnerability, an attacker must first obtain the secret key and have the knowledge of the cryptographic algorithm being used in the authentication process.”

Brizinov said that Claroty notified Rockwell of the vulnerability in 2019. Rockwell didn’t disclose it until Thursday. Rockwell also credited Kaspersky Lab and Soonchunhyang University researchers Eunseon Jeong, Youngho An, Junyoung Park, Insu Oh, and Kangbin Yim.

The vulnerability affects just about every Logix PLC Rockwell sells, including:

  • CompactLogix 1768
  • CompactLogix 1769
  • CompactLogix 5370
  • CompactLogix 5380
  • CompactLogix 5480
  • ControlLogix 5550
  • ControlLogix 5560
  • ControlLogix 5570
  • ControlLogix 5580
  • DriveLogix 5560
  • DriveLogix 5730
  • DriveLogix 1794-L34
  • Compact GuardLogix 5370
  • Compact GuardLogix 5380
  • GuardLogix 5570
  • GuardLogix 5580
  • SoftLogix 5800

Rockwell isn’t issuing a patch that directly addresses the problems stemming from the hard-coded key. Instead, the company is recommending that PLC users follow specific risk mitigation steps. The steps involve putting the controller mode switch into run, and if that’s not possible, following other recommendations that are specific to each PLC model.

Those steps are laid out in an advisory Rockwell is making available to customers, as well as in the above-linked CISA advisory. Rockwell and CISA also recommend PLC users follow standard security-in-depth security advice. Chief among the recommendations is ensuring that control system devices aren’t accessible from the Internet.

Security professionals universally admonish engineers to place critical industrial systems behind a firewall so they aren’t exposed to the Internet. Unfortunately, engineers struggling with high workloads and limited budgets often don’t heed the advice. The latest reminder of this came earlier this month when a municipal water treatment plant in Florida said that an intruder accessed a remote system and tried to lace drinking water with lye. Plant employees used the same TeamViewer password and didn’t put the system behind a firewall.

If Logix PLC users are segmenting industrial control networks and following other best practices, it’s unlikely that the risk posed by CVE-2021-22681 is minimal. And if people haven’t implemented these practices, hackers probably have easier ways to hijack the devices. That said, this vulnerability is serious enough that all Logix PLC users should pay attention to the CISA and Rockwell advisories.

Claroty has issued its own writeup here.

Google’s Smart TV software will have a “dumb TV” mode

Published

on

The new Google TV is a fine smart TV interface, but when it gets integrated into some TV sets later this year, its best feature might be that you can turn it off. A report from 9to5Google details an upcoming “Basic TV” mode that will be built into Google TV, which turns off just about all the smart TV features. Right now, Google TV is only available in the new Chromecast, but Google TV will be built into upcoming TVs from Sony and TCL. Basic mode means we’ll get smart TVs with a “dumb TV” mode.

The rise of smart TVs has led to the extinction of dumb TVs—today, basically every TV has some kind of computer and operating system built into it. If you’re actually expecting to live with a TV for several years, the problem with smart TVs is that the dirt-cheap computers inside these TVs don’t last as long as the display does. When your smart TV is a few years old, you might still have a perfectly good display panel, but you’ll be forced to interact with it through a slow, old, possibly abandoned integrated computer. Companies should sell dumb TVs without any of this crap permanently integrated into them, but if they refuse, letting consumers turn off the software is the next best thing.

When the new feature rolls out, you’ll be asked to choose between “Basic TV” or “Google TV” at setup. 9to5Google says that with basic mode, “almost everything is stripped, leaving users with just HDMI inputs and Live TV if they have an antenna plugged directly into the TV. Casting support, too, is dropped.” The UI notes that you’ll be turning off all apps, the Google Assistant, and personalized recommendations.

9to5 found this feature via the ADT-3 development set-top box and the Android 12 developer preview, so it’s not entirely clear how it will work when it’s running on a real TV. It seems like basic mode will only show a minimal set of icons for things like input-switching and settings. There’s also a big banner advertising Google TV mode, which you’ll presumably just have to learn to ignore. A Google spokesperson told the site that this feature is destined to hit TVs sold with integrated Google TV in the future.

If you’re wondering what the difference is between “Android TV” and “Google TV,” Google TV is kind of like the next version of Android TV. Google TV is just the Android TV codebase with a new interface, which offers things like a unified search. The upgrade path for existing Android TV devices is Google TV, assuming your device manufacturer is actually shipping updates. By 2022, Google says TV manufacturers won’t be allowed to ship Android TV and will instead ship Google TV. There are some product lines that Google just loves to rebrand every few years, and Android TV/Google TV is one of them.

Google TV will be in Sony’s entire Bravia XR 2021 lineup and select TCL TVs later this year.

Paramount+ will carry new Star Trek series Strange New Worlds and Prodigy

ViacomCBS

In an online event for investors, ViacomCBS revealed several new details about CBS All Access replacement Paramount+, including pricing as well as two new Star Trek series that will premiere on the network. Also, the company announced that a much-anticipated Showtime show will end up on Paramount+ instead.

Paramount+, which was announced several months ago, will launch on March 4 in the United States, Canada, and 18 Latin American countries. As with CBS All Access, both an ad-supported and ad-free plan will be offered. In the US, the ad-supported one will cost $4.99 per month, while the ad-free plan will cost $9.99.

That $4.99 per month is $1 cheaper than the ad-supported version of CBS All Access. However, this cheaper plan will not include local CBS stations. The service is also expected to launch in Nordic countries within a few weeks and in Australia sometime later this year.

When it launches, Paramount+ will have 2,500 films and 30,000 TV episodes, according to ViacomCBS executives. That will include some original series, many of which will be available in 4K and Dolby Vision HDR.

Original series will include those we’ve already seen on CBS All Access, including the large slate of Star Trek shows such as Discovery, Picard, and Lower Decks.

Two new Star Trek series have recently been announced: a CG animated kids’ show called Star Trek: Prodigy, and a spinoff about Captain Pike and Mr. Spock called Star Trek: Strange New Worlds. Prodigy was planned for airing on Nickelodeon (which is owned by the Viacom part of ViacomCBS), and it will still air there— but only after appearing on Paramount+ first.

Additionally, it has been confirmed that the long-anticipated and much delayed series based on the video game franchise Halo will be delivered via Paramount+; it was originally planned as a Showtime series. Steven Spielberg is an executive producer on the show, which is planned to premiere in the first quarter of 2022. According to Deadline, shooting was well underway when the pandemic forced a shutdown. During the break, it was decided to move the show to the broad-audience Paramount+ service rather than “adult” and “sophisticated” Showtime. (Those descriptors were used by Showtime exec David Nevins to describe the network.)

Other content includes a Frasier reboot, as well as some 2021 theatrical film releases like Mission Impossible 7.
