"Intel will have to defend itself against claims that the semiconductor goliath knew its microprocessors were defective and failed to tell customers," reports the Register: On Wednesday, Judge Michael Simon, of the US District Court of Oregon, partially denied the tech giant's motion to dismiss a class-action lawsuit arising from the 2018 public disclosure of Meltdown and Spectre, the family of data-leaking chip microarchitecture design blunders....

To defend against Meltdown and Spectre, Intel and other affected vendors have had to add software and hardware mitigations that for some workloads make patched processors mildly to significantly slower. The disclosure of related flaws has continued since that time, as researchers develop variations on the initial attacks and find other parts of chips that similarly expose privileged data. It is a problem that still is not entirely solved...

[L]awsuits have been consolidated into a multi-district proceeding known as "Intel Corp. CPU Marketing, Sales Practices and Products Liability Litigation" (3:18-md-02828-SI). And since 2018, Intel has been trying to get them to go away. Twice before the judge had dismissed the plaintiffs' complaint while allowing the plaintiffs to amend and refile their allegations. This third time, the judge only partially granted Intel's motion to toss the case. Judge Simon dismissed claims based on purchases up through August 2017 because Intel was unaware of the microarchitecture vulnerabilities up to that point. But he allowed seven claims, from September 2017 onward, to proceed, finding the plaintiffs' contention that Intel delayed disclosure of the flaws to maximize holiday season sales plausible enough to allow the case to move forward.

"Based on plaintiffs' allegations, it is not clear that Intel had a countervailing business interest other than profit for delaying disclosure for as long as it did (through the holiday season), for downplaying the negative effects of the mitigation, for suppressing the effects of the mitigation, and for continuing to embargo further security exploits that affect only Intel processors," the judge wrote in his order.

The Toronto Star just published a searing excerpt from the book Cobalt: Cradle of the Demon Metals, Birth of a Mining Superpower — written by a member of Canada's Parliament: It argues in part that "The social conflict that existed in the early days of Cobalt has been magnified a thousandfold in jurisdictions where the rule of law is compromised, and incursions into Indigenous territories heighten conflict." The world is searching for cobalt, the miracle ingredient of the digital age. The metal's capacity to store energy and stabilize conductors has made possible the proliferation of rechargeable batteries, smartphones and laptops. More crucially, in the face of catastrophic climate change, cobalt offers the hope of a clean-energy future. But cobalt has a much darker side. The relentless drive to feed the cobalt needs of Silicon Valley has led to appalling levels of degradation, child abuse and environmental damage in the Democratic Republic of Congo (DRC), the world's number one cobalt producer. The situation is so dire that human rights campaigners have denounced cobalt as the blood mineral of the 21st century.

In the 21st century, Canada's relationship to its resource extraction sector is coming under increasing scrutiny as we contemplate a world of melting ice and burning forests. So what can the story of Cobalt teach us in an age of pandemic, impending climate catastrophe, racial division and class strife? It may be that the shape-shifting metal will prove to be the miracle ingredient that leads us to a more sustainable way of life. Or it may be that we need to find a less rapacious balance between environment, social justice, human rights and the world's depleting resources.
The article points out that big tech companies "would love to cut their ties with the abuses in the Democratic Republic of Congo, but cobalt is an extremely elusive metal, and the struggle to secure cobalt supplies is taking place within the context of a much broader geopolitical struggle with China."

CBS News reports that foreign cyberattackers aren't the only potential threat to America's electrical power grid: Domestic violent extremists have been planning to try to disrupt the U.S. power grid and will probably keep doing so, according to a Department of Homeland Security intelligence bulletin shared with law enforcement agencies and utility operators Monday and obtained by CBS News. "Domestic violent extremists have developed credible, specific plans to attack electricity infrastructure since at least 2020, identifying the electric grid as a particularly attractive target given its interdependency with other infrastructure sectors," the bulletin reads. It warns that extremists "adhering to a range of ideologies will likely continue to plot and encourage physical attacks against electrical infrastructure."

Still, the bulletin notes that, "Absent significant technical knowledge or insider assistance, small scale attacks are unlikely to cause widespread, multi-state power loss but may result in physical damage that poses risks to operations or personnel."

"Former heads of nuclear regulatory bodies across Europe and the US put out a statement this week voicing their opposition to nuclear energy as a climate solution," reports The Verge's Justine Calma. The publication spoke with Gregory Jaczko, former chairman of the US Nuclear Regulatory Commission, to learn more about why some nuclear experts oppose the energy source as a climate fix. Slashdot reader Ol Olsoc shares an excerpt of the interview: Former NRC Chair Gregory Jaczko in an interview with the Verge notes: "I think there's been a lot of misinformation about the role that nuclear power can play in any climate strategy. A lot of attention has been put on nuclear as somehow the technology that's going to solve a lot of problems when it comes to dealing with climate change. I just think that's not true. And it's taking the debate and discussion away from the areas that can have a role and that do need focus and attention." He added: "I think it's money that's not well spent. Nuclear has shown time and time again that it cannot deliver on promises about deployment and costs. And that's really the most important factor when it comes to climate." Jaczko goes on to note how many of the nuclear plants when he was chairman were supposed to come online but have experienced delays and exceptional cost overruns. Two of the four new design reactors that were licensed when he was chairman, which were supposed to be starting production in 2016 and 2017, were canceled, "and that involved federal indictments for fraud among the heads of the company running that reactor development." The other two, he says, "continue to be pushed back and now are scheduled to start in 2022 or 2023" with a price tag that's over $30 billion.

If you're using either Dropbox or Microsoft OneDrive to sync files on a Mac, you'll want to pay attention to the release notes for today's macOS 12.3 beta: the update is deprecating a kernel extension used by both apps to download files on demand. Ars Technica reports: The extension means that files are available when you need them but don't take up space on your disk when you don't. Apple says that "both service providers have replacements for this functionality currently in beta." Both Microsoft and Dropbox started alerting users to this change before the macOS beta even dropped. Dropbox's page is relatively sparse. The page notifies users that Dropbox's online-only file functionality will break in macOS 12.3 and that a beta version of the Dropbox client with a fix will be released in March.

Microsoft's documentation for OneDrive's Files On-Demand feature is more detailed. It explains that Microsoft will be using Apple's File Provider extensions for future OneDrive versions, that the new Files On-Demand feature will be on by default, and that Files On-Demand will be supported in macOS 12.1 and later.

In addition to integrating better with the Finder (also explained by Microsoft here), using modern Apple extensions should reduce the number of obnoxious permission requests each app generates. The extensions should also reduce the likelihood that a buggy or compromised kernel extension can expose your data or damage your system. But the move will also make those apps a bit less flexible -- Microsoft says that the new version of Files On-Demand can't be disabled. That might be confusing if you expect to have a full copy of your data saved to your disk even when you're offline.

MattSparkes shares a report from New Scientist: Quantum computers would need to become around one million times larger than they are today in order to break the SHA-256 algorithm that secures bitcoin, which would put the cryptocurrency at risk from hackers. Breaking this impenetrable code is essentially impossible for ordinary computers, but quantum computers, which can exploit the properties of quantum physics to speed up some calculations, could theoretically crack it open.

[Mark Webber at the University of Sussex, UK, and his colleagues] calculated that breaking bitcoin's encryption in this 10 minute window would require a quantum computer with 1.9 billion qubits, while cracking it in an hour would require a machine with 317 million qubits. Even allowing for a whole day, this figure only drops to 13 million qubits. This is reassuring news for bitcoin owners because current machines have only a tiny fraction of this -- IBM's record-breaking superconducting quantum computer has only 127 qubits, so devices would need to become a million times larger to threaten the cryptocurrency, something Webber says is unlikely to happen for a decade. The study has been published in the journal AVS Quantum Science.

Manufacturers and other buyers of computer chips had less than five days' supply of some chips on hand late last year, leaving them vulnerable to any disruptions in deliveries, the Commerce Department reported Tuesday as it pushed Congress to endorse federal aid for chip makers. The Washington Post reports: Manufacturers' median chip inventory levels have plummeted from about 40 days' supply in 2019 to less than five days, according to a survey of 150 companies worldwide that the Commerce Department conducted in September. "This means a disruption overseas, which might shut down a semiconductor plant for 2-3 weeks, has the potential to disable a manufacturing facility and furlough workers in the United States if that facility only has 3-5 days of inventory," the Commerce Department concluded in a six-page summary of its findings.

The lack of chip inventory leaves auto manufacturers and other chip users with "no room for error," Commerce Secretary Gina Raimondo said Tuesday as she presented the findings. "A covid outbreak, a storm, a natural disaster, political instability, problem with equipment -- really anything that disrupts a [chip-making] facility anywhere in the world, we will feel the ramifications here in the United States of America," she said. "A covid outbreak in Malaysia has the potential to shut down a manufacturing facility in America."

"The reality is Congress must act," Raimondo added, urging lawmakers to pass a proposal for $52 billion in federal subsidies to incentivize construction of chip factories. "Every day we wait, we fall further behind." The Senate passed the measure last year. The legislation has been tied up for months in the House, though House Democrats are expected to introduce their version of the legislation as soon as this week. Industry executives say federal funding is likely to create more long-term supply of chips but not to alleviate the short-term shortages because chip factories take years to build.

MojoKid writes: Intel lifted its performance embargo today on its new line of Alder Lake 12th Gen Core mobile processors for laptops. Reviews are hitting the web specifically with Intel's higher-end Alder Lake-H processor SKU. Alder Lake is intended to be a single, scalable CPU architecture, designed to address PC client platforms from ultra-mobile solutions down to 9 watts, up to high-performance 125 Watt+ desktop solutions. Alder Lake-H, the foundation of the Core i9-12900HK 14-core/20-thread chip in this review at HotHardware has a 45W power envelope, but it will boost to much higher levels when power and thermal headroom is available. Coupled with NVIDIA's new GeForce RTX 3080 Ti mobile GPU, the machine put up some of the best gaming and content creation benchmark numbers ever recorded on a laptop.

Alder Lake-H CPU derivatives will scale back to 8-core chips with a mix of Performance cores and Efficiency cores consistent with Intel's new hybrid architecture. Additional benchmarks and performance recorded on the new Alienware x17 R2 with an identical hardware config were equally as impressive. Intel 12th Gen-powered laptops are starting to become available in market now, with lower power Alder Lake-U SKUs for thin and light machines arriving later this year.

Wired reports on 22-year-old Sam Zeloof, who builds semiconductors in his family's New Jersey garage, "about 30 miles from where the first transistor was made at Bell Labs in 1947." With a collection of salvaged and homemade equipment, Zeloof produced a chip with 1,200 transistors. He had sliced up wafers of silicon, patterned them with microscopic designs using ultraviolet light, and dunked them in acid by hand, documenting the process on YouTube and his blog. "Maybe it's overconfidence, but I have a mentality that another human figured it out, so I can too, even if maybe it takes me longer," he says... His chips lag Intel's by technological eons, but Zeloof argues only half-jokingly that he's making faster progress than the semiconductor industry did in its early days. His second chip has 200 times as many transistors as his first, a growth rate outpacing Moore's law, the rule of thumb coined by an Intel cofounder that says the number of transistors on a chip doubles roughly every two years.

Zeloof now hopes to match the scale of Intel's breakthrough 4004 chip from 1971, the first commercial microprocessor, which had 2,300 transistors and was used in calculators and other business machines. In December, he started work on an interim circuit design that can perform simple addition....

Garage-built chips aren't about to power your PlayStation, but Zeloof says his unusual hobby has convinced him that society would benefit from chipmaking being more accessible to inventors without multimillion-dollar budgets. "That really high barrier to entry will make you super risk-averse, and that's bad for innovation," Zeloof says.

nickwinlund77 shares a report from SciTechDaily: UNSW Sydney-led research paves the way for large silicon-based quantum processors for real-world manufacturing and application. Australian researchers have proven that near error-free quantum computing is possible, paving the way to build silicon-based quantum devices compatible with current semiconductor manufacturing technology. [...] [The researcher's] paper is one of three published today in Nature that independently confirm that robust, reliable quantum computing in silicon is now a reality. This breakthrough is featured on the front cover of the journal.

[Professor Andrea Morello of UNSW, who led the work] et al achieved 1-qubit operation fidelities up to 99.95 percent, and 2-qubit fidelity of 99.37 percent with a three-qubit system comprising an electron and two phosphorous atoms, introduced in silicon via ion implantation. A Delft team in the Netherlands led by Lieven Vandersypen achieved 99.87 percent 1-qubit and 99.65 percent 2-qubit fidelities using electron spins in quantum dots formed in a stack of silicon and silicon-germanium alloy (Si/SiGe). A RIKEN team in Japan led by Seigo Tarucha similarly achieved 99.84 percent 1-qubit and 99.51 percent 2-qubit fidelities in a two-electron system using Si/SiGe quantum dots.

The UNSW and Delft teams certified the performance of their quantum processors using a sophisticated method called gate set tomography, developed at Sandia National Laboratories in the U.S. and made openly available to the research community. Morello had previously demonstrated that he could preserve quantum information in silicon for 35 seconds, due to the extreme isolation of nuclear spins from their environment. But the trade-off was that isolating the qubits made it seemingly impossible for them to interact with each other, as necessary to perform actual computations. Today's paper describes how his team overcame this problem by using an electron encompassing two nuclei of phosphorus atoms. The three papers from the UNSW team, Delft team and RIKEN group in Tokyo can be found at their respective links.

AMD's GPU technology is returning to mobile handsets with Samsung's Exynos 2200 system-on-chip, which was announced on Tuesday. The Register reports: The Exynos 2200 processor, fabricated using a 4nm process, has Armv9 CPU cores and the oddly named Xclipse GPU, which is an adaptation of AMD's RDNA 2 mainstream GPU architecture. AMD was in the handheld GPU market until 2009, when it sold the Imageon GPU and handheld business for $65m to Qualcomm, which turned the tech into the Adreno GPU for its Snapdragon family. AMD's Imageon processors were used in devices from Motorola, Panasonic, Palm and others making Windows Mobile handsets. AMD's now returning to a more competitive mobile graphics market with Apple, Arm and Imagination also possessing homegrown smartphone GPUs.

Samsung and AMD announced the companies were working together on graphics in June last year. With Exynos 2200, Samsung has moved on from Arm's Mali GPU family, which was in the predecessor Exynos 2100 used in the current flagship Galaxy smartphones. Samsung says the power-optimized GPU has hardware-accelerated ray tracing, which simulates lighting effects and other features to make gaming a better experience. [...] The Exynos 2200 has an image signal processor that can apparently handle 200-megapixel pictures and record 8K video. Other features include HDR10+ support, and 4K video decoding at up to 240fps or 8K decoding at up to 60fps. It supports display refresh rates of up to 144Hz.

The eight-core CPU cluster features a balance of high-performing and power-efficient cores. It has one Arm Cortex-X2 flagship core, three Cortex-A710 big cores and four Cortex-A510s, which is in the same ballpark as Qualcomm's Snapdragon 8 Gen 1 and Mediatek's Dimensity 9000, which are the only other chips using Arm's Armv9 cores and are made using a 4nm process. An integrated 5G modem supports both sub-6GHz and millimeter wave bands, and a feature to mix LTE and 5G signals speeds up data transfers to 10Gbps. The chip also has a security processor and an AI engine that is said to be two times faster than its predecessor in the Exynos 2100.

An anonymous reader quotes a report from New Atlas: For the first time, a team of scientists has now demonstrated the quantum mechanical principle of superabsorption that underpins quantum batteries in a proof-of-concept device. "Superabsorption is a quantum collective effect where transitions between the states of the molecules interfere constructively," James Quach, corresponding author of the study, told New Atlas. "Constructive interference occurs in all kinds of waves (light, sound, waves on water), and occurs when different waves add up to give a larger effect than either wave on its own. Crucially this allows the combined molecules to absorb light more efficiently than if each molecule were acting individually." In a quantum battery, this phenomenon would have a very clear benefit. The more energy-storing molecules you have, the more efficiently they'll be able to absorb that energy -- in other words, the bigger you make the battery, the faster it will charge. At least, that's how it should work in theory. Superabsorption had yet to be demonstrated on a scale large enough to build quantum batteries, but the new study has now managed just that.

To build their test device, the researchers placed an active layer of light-absorbing molecules -- a dye known as Lumogen-F Orange -- in a microcavity between two mirrors. "The mirrors in this microcavity were made using a standard method to make high quality mirrors," explained Quach. "This is to use alternating layers of dielectric materials -- silicon dioxide and niobium pentoxide -- to create what is known as a 'distributed Bragg reflector.' This produces mirrors which reflect much more of the light than a typical metal/glass mirror. This is important as we want light to stay inside the cavity as long as possible." The team then used ultrafast transient-absorption spectroscopy to measure how the dye molecules were storing the energy and how fast the whole device was charging. And sure enough, as the size of the microcavity and the number of molecules increased, the charging time decreased, demonstrating superabsorption at work. "The idea here is a proof-of-principle that enhanced absorption of light is possible in such a device," Quach told New Atlas. "The key challenge though is to bridge the gap between the proof-of-principle here for a small device, and exploiting the same ideas in larger usable devices. The next steps are to explore how this can be combined with other ways of storing and transferring energy, to provide a device that could be practically useful."

The research was published in the journal Science Advances.

1.77 million people live in South Australia, speading across 984,321 square kilometres (or 380,048 square miles), according to Wikipedia. Today the Sydney Morning Herald announced that South Australia "sourced an average of just over 100 per cent of the electricity it needed from renewable power for 6 and a half days leading up to December 29 last year."

They're calling it "a record for the state and perhaps for comparable energy grids around the world." The state's previous record was just over three days, says Geoff Eldridge, an energy analyst who runs the website NEMlog.com.au, which tracks the operations of the National Energy Market covering Australia's east-coast states and South Australia.

His analysis shows that for the six days identified, the state produced on average 101 per cent of the energy it needed from wind, rooftop solar and solar farms, with just a fraction of the energy the state used being drawn from gas, in order to keep the grid stable. At times during the period, slightly less renewable energy was available and at other times renewable capacity was higher than needed, he says.

Bruce Mountain, director of the Victoria Energy Policy Centre, said he believed that aside from some small island grids such as those in Hawaii and Tasmania, it was likely that South Australia's six-day run on renewables was a record for a grid supporting an advanced economy.

During the unprecedented 156-hour renewable run, the share of wind in total energy supplied averaged 64.4 per cent, while rooftop solar averaged 29.5 per cent and utility-scale solar averaged 6.2 per cent, clean energy website RenewEconomy.com.au reported, using Mr Eldridge's data.

"The PineNote is a tablet with a 10.1 inch grayscale E Ink display and pen support," reports Liliputing.

"It's designed to be a hackable, Linux-friendly device and it's one of the latest products from the makers of the PinePhone and PineBook line of devices." First introduced last summer, the PineNote began shipping to developers in limited quantities in December. Now it's available for anyone to purchase for $399 — no invitation required. But it's probably only a good idea to buy one if you're a developer or very early adopter because there's very little software available for the PineNote so far. At this point, Pine64 is shipping the PineNote without an operating system installed. It will have only a bootloader, allowing developers and enthusiasts to load their own software... [D]evelopers have already made some progress in getting builds Alpine and Debian Linux to run on the E Ink slate, and according to Pine64, there are ports for NixOS and other operating systems on the way.

There's already a partially working display driver, but it's still a work in progress. The goal is to allow developers to port mainline Linux operating systems and applications to play well with a monochrome display with a slow refresh rate. Developers have also figured out how to enable support PineNote's touchscreen, audio playback, and USB port, making it possible to use USB keyboards, storage devices, and other peripherals.

The new German government is proposing a bold new initiative to dramatically increase onshore wind power in the country by 2030. "If successful, the plan would add up to 10 gigawatts of new onshore wind capacity every year for the rest of the decade," reports CleanTechnica. "In total, 2% of Germany's land area will be set aside for wind energy generation. [T]he German government also plans to increase its offshore wind target to 30 GW by 2030." From the report: During a press conference, [the nation's new Green Minister for Economics and Climate, Robert Habeck] made it clear that wind energy, particularly onshore wind, will remain the most important source of electricity in Germany and is the key to further emission reductions, according to WindEurope. "The Energiewende is roaring again. Germany wants a huge expansion of onshore wind. And the Government fully understands that that requires faster permitting of new wind farms -- and they intend to deliver this ASAP with a dedicated new 'Onshore Wind Law.' Today's announcements mark the comeback of German leadership on renewables -- fantastisch!" says WindEurope CEO Giles Dickson.

Habeck intends to remove restraints on onshore wind development caused by concerns about radar installations for civilian and military aviation. He estimates the government plan could free up 4 to 5 GW of new wind projects currently blocked by aviation radar, and an additional 4 GW currently blocked by the military. Support for renewable energies will be paid from the state budget, reducing the burden on low income households and small businesses. The package is also said to define the energy transition as a 'matter of public interest' in order to prioritize wind energy projects over other forms of land use -- an important precondition to streamlining the permit process and finding new sites for wind energy projects.

An anonymous reader quotes a report from Electrek: New satellite images show that Tesla significantly expanded its rooftop solar array at Gigafactory Nevada as it aims for it to become the world's biggest. In 2017, Tesla announced plans for a giant 70 MW rooftop array at Gigafactory Nevada, which would be the largest in the world by a wide margin. The project has been lagging for a long time. Tesla finally started construction of the solar array in 2018 and expanded on it throughout the next few years, but it has never grown near the size Tesla has been talking about. Last summer, the automaker said that it had deployed 3.2 MW at the site. At the time, Tesla also changed its goal to deploy 24 MW instead of 70 MW on the rooftop of the factory, which itself is now smaller than originally planned. The company said that it believes this would still be enough to be the largest rooftop deployment of solar power. To be fair, there are much bigger solar farms than 24 MW out there, but Tesla is specifically talking about rooftop solar arrays and not ground-mounted installations.

Now a few months later, it looks like Tesla has made a lot of progress with several more MW of solar power deployed at Gigafactory Nevada based on new satellite images. The image on the left is from September 2021 and the one on the right is from yesterday, January 12 (via Building Tesla). It's hard to determine exactly how much capacity Tesla deployed, but it looks like a significant increase over the last few months. As for the factory itself, it has been expanding in size for a long time. The factory has been producing a lot of battery cells, packs, and drivetrains for Tesla, but the giant structure has been stuck at ~30% completion for the past four years.

The PC market experienced its first big growth in a decade during 2020, when the pandemic began to force people to work and learn from home. Market research firms Gartner and IDC are now reporting that the worldwide PC market has grown again throughout 2021, as demand for traditional PCs continued during a global chip shortage. From a report: Nearly 340 million PCs were shipped in 2021, according to Gartner. That's a nearly 10 percent increase over the already unprecedented numbers seen in 2020. IDC puts the figure at 348.8 million, up nearly 15 percent. "2021 has truly been a return to form for the PC," said Jitesh Ubrani, a research manager at IDC. "Consumer need for PCs in emerging markets and global commercial demand remained strong during the quarter with supply being a gating factor." Ongoing supply issues relating to a global chip shortage mean the PC market "could have been even larger than it was in 2021," according to Tom Mainelli, an executive at IDC. Gartner reports that 2021 saw the highest shipment volume of PCs since 2013, after a 2017 milestone of five years of PC decline.

The US government announced Wednesday it will auction more than 480,000 acres off the coasts of New York and New Jersey to build wind farms as part of its campaign to supply renewable energy to more than 10 million homes by 2030. Tech Xplore reports: Offshore wind developers will bid February 23 on six areas in the New York Bight -- the most lots ever offered in a single auction -- which could generate between 5.6 to seven gigawatts of energy, enough to power two million homes, the Interior Department said. The auction will be the first under President Joe Biden, whose administration aims to build as many as to seven major offshore wind farms and review plans for at least 16 others along the US coasts. The effort is part of Washington's fight against climate change, and the Biden administration says the wind investment would cut 78 million tons of carbon dioxide emissions and create tens of thousands of jobs.

According to Electrek, the number of Gogoro electric scooter battery swap stations in Taiwan will soon eclipse the country's total number of gas stations. From the report: Gogoro's battery swap stations look something like a bright green and white vending machine. Users of Gogoro's batteries (which include scooters of many different brands thanks to its partnerships), simply roll up to a station and swap out their depleted battery for a freshly charged unit. A subscription service makes it a quick and easy process that takes just a few seconds. At the end of 2021, Gogoro counted a total of 2,215 GoStations nationwide, according to the Taipei Times. The number of gas stations stood barely higher at 2,487. At Gogoro's current rate of expansion, 2022 very well may be the year that the number of GoStations surpasses the number of gas stations.

An anonymous reader quotes a report from Gizmodo: A team of researchers at France's Research Institute of Computer Science and Random Systems created an anti-malware system centered around a Raspberry Pi that scans devices for electromagnetic waves. As reported by Tom's Hardware, the security device uses an oscilloscope (Picoscope 6407) and H-Field probe connected to a Raspberry Pi 2B to pick up abnormalities in specific electromagnetic waves emitted by computers that are under attack, a technique the researchers say is used to "obtain precise knowledge about malware type and identity."

The detection system then relies on Convolution Neural Networks (CNN) to determine whether the data gathered indicates the presence of a threat. Using this technique, researchers claims they could record 100,000 measurement traces from IoT devices infected by genuine malware samples, and predicted three generic and one benign malware class with an accuracy as high as 99.82%. Best of all, no software is needed and the device you're scanning doesn't need to be manipulated in any way. As such, bad actors won't be successful with their attempts to conceal malicious code from malware detection software using obfuscation techniques. "Our method does not require any modification on the target device. Thus, it can be deployed independently from the resources available without any overhead. Moreover, our approach has the advantage that it can hardly be detected and evaded by the malware authors," researchers wrote in the paper.
