rC3: Stress test leads to many iPhone crashes

Communication chips that Apple uses in iPhones only withstand endurance tests to a limited extent. This was demonstrated by Jiska Classen from the research group for mobile radio security at the TU Darmstadt at the remote Chaos Communication Congress (rC3). Again and again you could see on their recordings how the devices “said goodbye” in an uncontrollable state – sometimes with unusual sound effects. They lost their “orientation” and some had to be reset to their original state.

Classen used the fuzzing method for her experiments. In this case, large amounts of random data are continuously sent to the system to be tested via one or more input interfaces in order to automatically check its robustness. The scientist focused on the baseband chip, which is responsible for network functions such as telephony, SMS transmission and internet access. By smuggling in manipulated data packets, according to their thesis, security gaps in the higher-level, actually shielded iOS operating system could then possibly be exploited in order to execute their own commands.

New approaches for mobile radio research This strategy is already very interesting from the perspective of reverse engineering, i.e. the replication of critical proprietary functions, stated Classen. In the resulting profiles you can see a lot of messages for baseband management. With iPhones, on which usage restrictions have been removed by jailbreak, you can smuggle in data packets and change the behavior of the modem without any problems. This paves the way for new approaches in mobile communications research.

Specifically, the expert initially felt the chips and devices via Wireless Protocol Fuzzing on the tooth, so subjected the protocol implementations for wireless communication to a stress test. To do this, she sent images to the image parser responsible for processing to see what was being executed and how. She combined the relevant files into a corpus and supplemented this with standard-compliant JPEGs and artificially generated images. So she could see which files caused a crash and what exactly was the cause.

Ddd-di-di-dd-di-d-di-d -di-d-dimm! Classen also succeeded in replacing bits and bytes with his own data and smuggling them in during ongoing calls or incoming short messages. After observing the effects that the manipulated data induced, she was able to refine the method and send large amounts of short messages to the baseband chip. The iPhone then received so many text messages in a short time that it no longer had time to play the typical dimming tone for each one. Instead, only an unspecific “Ddd-di-di-dd-di-d-di-d-di-d-dimm” could be heard.

Classen was also able to force calls to hotlines to be dropped, whereby the tested iPhone repeated the last syllables of an announcement in a staccato manner. In another case, the user should re-enter his PIN; at other times, the test device constantly reported a busy line by mistake. In another demo, an SMS could no longer be deleted, so a reset was necessary. According to the researcher, the process can still be expanded, as many functions could not be carried out even with a good starting body.

Frankenstein module for Bluetooth Classen also showed in her lecture which fuzzers she used and how she adapted and combined these tools for the iPhone chips with her own code. So far, the research group has mainly examined Bluetooth chips. Team colleague Jan Ruge built a module called “Frankenstein” to emulate the Bluetooth firmware at the same speed as with conventional hardware and thus to be able to carry out realistic tests for complete protocol stacks.

As The scientist named ToothPicker, Frida as well as DTrace and American Fuzzy Lop (AFL) as other helpful tools. In some cases, she let this fuzzer run for several weeks and thus repeatedly generated crashes, for example on the iPhone models 7 and 8, and discovered weak points. Some problems would also have extended to the macOS desktop and laptop operating system. One hurdle was that the channels were closed after receiving some invalid packets when establishing a wireless connection. This behavior could be turned off with Frida.

Undocumented remote interface With the Analyzes revealed Classen differences between iPhone 8 models for the US and Europe. While the USA variant contains a Qualcomm chip with the documented MSM interface (QMI), the European variant contains an Intel chip with a previously largely unknown interface called Apple Remote Invocation (ARI). Data packets sent over the air could in principle control these two interfaces, even if an intermediate layer was built in. The two different libraries could be fuzzed with Frida. In some cases, the CommCenter was taken out of service, calls were lost and Internet connections had to be re-established. Sometimes the virtual communication center continued to run and also processed packets with incorrect values.

During the tests, Classen made an iPhone 8 almost unusable. The start-up procedure only ran until pongoOS before the actual boot process of the iOS. Normal starting was only possible after a few hours. The Intel variant noted log files totaling 500 megabytes, so that the internal memory quickly filled up. Then the deletion of photos no longer worked and SSH logins failed.

In general, fuzzing would “confuse iPhones very much”, explained the researcher. They requested reactivation, lost their location function and displayed flash messages highlighted in gray. There is still a lot of leeway for hackers to try out. But it is better not to use your private smartphone for this. Classen sent crash reports and information about possible security holes to Apple. The group has identified the major weaknesses with the iOS updates 14. 2 and 14. 3 closed.

11 great apps ready for your new 2020 M1 Mac

This year marked the introduction of the first Macs to be powered by Apple’s own silicon instead of Intel chips. As is evidenced by our reviews of the M1 MacBook Air, 13-inch MacBook Pro, and Mac mini, these machines are incredibly powerful and offer wicked fast performance. This is especially true for apps that are designed to run natively on them and take full advantage of Apple’s latest technologies.

So in that vein, this year’s Mac apps list is going to focus on some of the software that has already been optimized for this new era of Apple hardware. Last year’s picks remain just as relevant and useful today if you’re on an Intel machine. But if you’ve been gifted (or are gifting yourself) one of these new speed-demon Macs, these are a few great ways of sampling what they can do.

We’ve rounded up our favorite and most-used games, apps, and entertainment. Check out our app picks for iPhones, Android phones, Windows PCs, and M1-equipped Macs; our favorite mobile games from Apple Arcade and Google Play Pass; and our top choices for gaming PCs, the PS5, Xbox One and Series X / S, Nintendo Switch, and VR. We’ve also listed our favorite streaming shows on Disney Plus, Hulu, ESPN Plus, and Netflix; some great sci-fi books; and exciting new podcasts. (Note: pricing was accurate at the time of publishing but may change.)

Pixelmator Pro

Pixelmator Pro

Pixelmator Pro is one of the very best image editing apps for the Mac. It has the usual set of RAW editing tools, presets, sophisticated layer editing, and photo filters, and makes it easy to control every detail of your images. What sets Pixelmator Pro apart are the automatic adjustments it can make through a machine learning algorithm that has been trained with over 20 million photos. The latest update also allows greater customizability over the interface, letting you put everything where it makes the most sense for your workflow. And in a world where many creative apps demand a subscription, I really appreciate the one-time $19.99 price for everything this app gives you.

Pixelmator Pro’s iPad app ($4.99) is also wonderful — especially if you like retouching things with your Apple Pencil, which is how I edit many of my review photos.

Lightroom

Lightroom

Lightroom is the first of Adobe’s hugely popular apps to be optimized for Apple’s M1 silicon. And for many people, it’s the default choice for editing and organizing their photo collection. Now the app has been updated to leverage the power of Apple’s M1 chip to make that editing go even quicker.

Keep in mind this is the regular version of Lightroom; Lightroom Classic doesn’t run natively on M1, but Adobe says there are no known issues running it through Rosetta 2 translation. In my experience, Lightroom Classic feels very similar to its performance on Intel Macs.

A native M1 version of Photoshop is set to follow sometime next year, but Adobe hasn’t given release time frames for other apps such as Premiere Pro.

Google Chrome and Firefox

Google Chrome

Two major browsers, Chrome and Firefox, have already been updated to run natively on M1 Macs, so you shouldn’t encounter any issues or irregular performance drops when using either. In the case of Chrome, just be sure that you select “Mac with Apple chip” when downloading — otherwise you’ll end up installing the Intel version, which will still run, but not as efficiently.

Microsoft Edge currently has M1 support in its beta channel, so that shouldn’t be too far off either.

Fantastical

Fantastical

If Apple’s built-in Calendar app isn’t doing it for you, then Fantastical might be the more advanced alternative you’re looking for. Its natural language parser can turn normal sentences about your plans into a perfectly formatted appointment entry. You can set your calendar view in exactly the way you want, and Fantastical also has widgets that you can pop into your Mac’s “Today” sidebar. There is a basic free version; the Premium version, which starts at $4.99 a month, offers additional features such as the ability to add tasks, full screen views, and calendar syncing.

Microsoft 365

Microsoft 365

Microsoft has quickly updated its entire Mac suite to fully optimize Word, PowerPoint, Excel, Outlook, and OneNote for M1. So you should notice very speedy performance when doing work with any of them. I’m sure many people will prefer these over Apple’s own productivity apps like Pages and Numbers.

Twitter

Twitter

Hear me out: the Twitter app for macOS has actually gotten very good. It took some polishing and bug fixes to reach this point, but Twitter for Mac is now full-featured, responsive, and not nearly as crash-prone as before. If you haven’t given Twitter’s native app a chance yet, now’s a great time.

If you still prefer a third-party app, Tweetbot remains the go-to, and it’s also universal and M1-ready.

iMazing

iMazing

iMazing is a great device manager for digging into everything residing on your iPhone or iPad. You can create backups (different from the regular Apple ones) and grab your messages, photos, music, and more right off the device.

But it was also discovered soon after the launch of M1 Macs that this software can be used to “side load” and install iPhone apps — even those that have not yet opted in — to macOS. If you’re experimenting with this, just expect that not everything will work flawlessly.

iMazing also recently added the option to clearly see which apps on your system are universal or developed for Intel.

Bartender

Bartender

If you’ve got a cluttered mess of a menu bar at the top of your Mac’s screen, Bartender can help you bring order to things. A longtime favorite macOS utility of ours, this app lets you neatly hide everything under one menu bar icon to ease up on the chaos. You can also set triggers so that certain icons only show at those times when it makes the most sense.

Neural Mix Pro

Neural Mix Pro

Neural Mix Pro is an app that lets you separate the various parts of a song — vocals, instrumentation, and beats — and listen to them individually. You can also change up the tempo of a song without ruining the pitch. A handy tool for DJs and musicians, it also just appeals to my inner music nerd. The end result can still sometimes sound a bit phase-y (like most vocal remover software) and have some artifacts, but it does a better job than other apps I’ve tried for this purpose. Just know that it’s pricey compared to other recommendations here; you’ll have to pay $50 to unlock the app.

BetterTouchTool

BetterTouchTool

If you’ve got the new 13-inch MacBook Pro with Apple’s M1 chip, well, that means you’ve also got the love-it-or-hate-it Touch Bar above your keyboard. There are ways of customizing it to your liking in macOS settings, but BetterTouchTool is a utility that gives you even greater flexibility over what goes where when using the Touch Bar, allowing you to quickly tap useful shortcuts for your most important apps.

Thermaltake Toughfan 12 Turbo fans add more static pressure for RL radiators

by Antonio Delgado Ago 10 minutes

Based on the recently launched Thoughfan liquid cooling fans 10, the new Turbo variant further increases its static pressure to achieve higher performance in cooling radiators for high performance liquid cooling systems.

The Thoughfan 12 turbo offers a static pressure of 3. 78 mm-H2O

Specifically, the Thermaltake Toughfan 12 Turbo increase their static pressure to a maximum of 3.78 mm-H2O, a considerable increase from 2. 41 mm-H 2 Or the older version “no turbo”. For this, the maximum rotation speed has been increased to 2. 500 RPM, operating in a range that goes from that maximum to a minimum of 500 RPM managed by PWM.

The maximum airflow increases up to 69, 69 CFM and naturally all this has a direct influence on their sound levels which increase to a maximum of 24, 1 dBA to 2. 434 RPM.

The Thermaltake ToughFan 12 Turbo are already available from today in Spain through the company’s online store for a price of 24, 434 euros.
