This WeeΚ In Security: Hackerman, Twitter’s Best, And Signs To Watch Out For

April 1, 2022 by Jonathan Bennett 6 Comments

[Editor’s note: There is a second, fake iteration of this column out today. This is obviously the real column.]

First off, there’s an amazing video tutorial from [Hackerman], embedded below the break. It’s a beginners guide to temporal displacement through GPU accelerated, cellular-connected partition board. The central flaw that makes this possible is a segmentation violation, accessible through a mode 6 cursor address reset. Watch out, though, because many mainframes actually have a core terminal capable of shutting such an attempt out of the grid altogether.

It’s a great guide, and definitely worth a watch if temporal security tickles your fancy. Watch out, though, because everyday objects can apparently act as bridges, infecting even users with temporal effects.

Watching A Spacewalk In Real Time

March 31, 2022 by Al Williams 6 Comments

If you go to, say, a football game, you probably don’t get to see as much of the game as close as you do when you stay home and watch on TV. But there’s something about being there that counts. That’s probably how [Sebastian Voltmer] feels. While we’ve all seen video of astronauts and cosmonauts spacewalking, [Sebastian] managed to take a snapshot of a pair of spacewalkers from his telescope.

Of course, this wasn’t your ordinary department store Christmas gift telescope. The instrument was a Celestron 11 inch EdgeHD Schmidt-Cassegrain telescope on a very expensive GM2000 HPS mount. An ASI290 planetary camera took the shot. You can see the gear and more about the photos in the video below.

Desktop Performance In A Custom Mac Laptop

March 24, 2022 by Bryan Cockfield 17 Comments

Most of us either own or have used a laptop at some point. For traveling, as a student, or even for browsing Hackaday on the couch in front of the TV, they are pretty much indispensable. They do tend to have a sharp performance reduction compared to a desktop though thanks to the thermal and battery limitations of a portable form factor. [Scott Yu-Jan] wanted to solve that in his own life by building a custom Mac laptop with none of these downsides.

Noticing that a modern iPad Mini has exactly the same width of his Mac Mini, [Scott] set about combining the two devices into a single unit that he could assemble when traveling. A 3D printed case with a traditional laptop clamshell design takes care of physically combining these two devices, and a USB-C cable between the two takes care of combining them in software thanks to Apple’s Duet program. While this has better performance than a Macbook Pro it might actually have some perks, since Apple continues to refuse to make a laptop with a touchscreen.

There are some downsides, of course. The price is higher than a comparable Macbook Pro for the iPad and Mac together, plus it doesn’t include a keyboard or mouse. It also has no battery, so it needs to be plugged in. In the follow-up video linked below, though, [Scott] notes that for him this still made sense as he uses the Mac and iPad individually already, and only works remotely at places that have power outlets readily available. For the average person, though, we might recommend something different if you really need an esoteric laptop-like machine.

Thanks to [Varun] for originally sending in this tip!

NVIDIA Unveils Jetson AGX Orin Developer Kit

March 22, 2022 by Tom Nardi 14 Comments

When you think of high-performance computing powered by NVIDIA hardware, you probably think of applications leveraging the capabilities of the company’s graphics cards. In many cases, you’d be right. But naturally there are situations where the traditional combination of x86 computer and bolt-on GPU simply isn’t going to cut it; try packing a modern gaming computer onto a quadcopter and let us know how it goes.

For these so-called “edge computing” situations, NVIDIA offers the Jetson line of ARM single-board computers which include a scaled-down GPU that gives them vastly improved performance for machine learning applications than something like the Raspberry Pi. Today during their annual GPU Technology Conference (GTC), NVIDIA announced the immediate availability of the Jetson AGX Orin Developer Kit, which the company promises can deliver “server-class AI performance” in a package small enough for use in IoT or robotics.

As with the earlier Jetsons, the palm-sized development kit acts as a sort of breakout board for the far smaller module slotted into it. This gives developers access to the full suite of the connectivity and I/O options offered by the Jetson module in a desktop-friendly form that makes prototyping the software side of things much easier. Once the code is working as intended, you can simply pop the Jetson module out of the development kit and install it in your final hardware.

NVIDIA is offering the Orin module in a range of configurations, depending on your computational needs and budget. At the high end is the AGX Orin 64 GB at $1599 USD; which offers a 12-core ARM Cortex-A78AE processor, 32 GB of DDR5 RAM, 64 GB of onboard flash, and a Ampere GPU with 2048 CUDA cores and 64 Tensor cores, which all told enables it to perform an incredible 275 trillion operations per second (TOPS).

At the other end of the spectrum is the Orin NX 8 GB, a SO-DIMM module that delivers 70 TOPS for $399. It’s worth noting that even this low-end flavor of the Orin is capable of more than double the operations per second as 2018’s Jetson AGX Xavier, which until now was the most powerful entry in the product line.

The Jetson AGX Orin Developer Kit is available for $1,999 USD, and includes the AGX Orin 64 GB module. Interestingly, NVIDIA says the onboard software is able to emulate any of of the lower tier modules, so you won’t necessarily have to swap out the internal modules if your final hardware will end up using one of the cheaper modules. Of course the inverse of that is even folks who only planned on using the more budget-friendly units either have to shell out for an expensive dev kit, or try to spin their own breakout board.

While the $50 USD Jetson Nano is far more likely to be on the workbench of the average Hackaday reader, we have to admit that the specs of these new Orin modules are very exciting. Then again, we’ve covered several projects that used the previously top-of-the-line Jetson Xavier, so we don’t doubt one of you is already reaching for their wallet to pick up this latest entry into NVIDIA’s line of diminutive powerhouses.

One Giant Leap (Backwards) For Humankind: What The Russia-Ukraine War Means For The ISS

March 21, 2022 by Adam Zeloof 89 Comments

The International Space Station was built not only in the name of science and exploration, but as a symbol of unity. Five space agencies, some representing countries who had been bitter Cold War rivals hardly a decade before the ISS was launched, came together to build something out of a sci-fi novel: a home among the stars (well, in Low Earth Orbit) for humans from around the globe to work with one another for the sake of scientific advancement, high above the terrestrial politics that governed rock below. That was the idea, at least.

So far, while there has been considerable sound and fury in social media channels, international cooperation in space seems to continue unhindered. What are we to make of all this bluster, and what effects could it have on the actual ISS?

Clockwork DevTerm R-01 Takes RISC-V Out For A Spin

March 19, 2022 by Tom Nardi 23 Comments

If you’re anything like us you’ve been keeping a close eye on the development of RISC-V: an open standard instruction set architecture (ISA) that’s been threatening to change the computing status quo for what seems like forever. From its humble beginnings as a teaching tool in Berkeley’s Parallel Computing Lab in 2010, it’s popped up in various development boards and gadgets from time to time. It even showed up in the 2019 Hackaday Supercon badge, albeit in FPGA form. But getting your hands on an actual RISC-V computer has been another story entirely. Until now, that is.

Clockwork has recently announced the availability of the DevTerm R-01, a variant of their existing portable computer that’s powered by a RISC-V module rather than the ARM chips featured in the earlier A04 and A06 models. Interestingly the newest member of the family is actually the cheapest at $239 USD, though it’s worth mentioning that not only does this new model only include 1 GB of RAM, but the product page makes it clear that the RISC-V version is intended for experienced penguin wranglers who aren’t afraid of the occasional bug.

Newbies are persona non grata for the R-01.

Beyond the RISC-V CPU and slimmed down main memory, this is the same DevTerm that our very own [Donald Papp] reviewed earlier this month. Thanks to the modular nature of the portable machine, this sort of component swapping is a breeze, though frankly we’re impressed that the Clockwork team is willing to go out on such a limb this early in the product’s life. In our first look at the device we figured at best they would release an updated CPU board to accommodate the Raspberry Pi 4 Compute Module, but supporting a whole new architecture is a considerably bolder move. One wonders that other plans they may have for the retro-futuristic machine. Perhaps a low-power x86 chip isn’t out of the question?

This Week In Security: More Protestware, Another Linux Vuln, And TLStorm

March 18, 2022 by Jonathan Bennett 13 Comments

It seems I have made my tiny, indelible mark on internet security history, with the term “protestware“. As far as I can tell, I first coined this particular flavor of malware while covering the Faker.js/Colors.js vandalism in January.

Yet another developer, [RIAEvangelist] has inserted some malicious code (Mirror, since the complaint has been deleted) in an existing project, in protest of something, in this case the war in Ukraine. The behavior here is to write a nice note on the desktop, preaching “peace not war”. However, a few versions of this sample have a nasty surprise — it does a GeoIP lookup, and attempts to wipe the entire drive if it detects a Russian location. Yes, node-ipc versions 10.1.1 and 10.1.2 contain straight-up malware. It’s not clear how many users ran the potentially malicious code, as it was quickly reverted and released 10.1.3. Up-to-date versions of node-ipc still create the desktop file, and Unity Hub has already confirmed they shipped the library in this state, and have since issued a hotfix.
