SEO Expert Hired and Fired By Ashley Madison Turned on Company, Promising Revenge (krebsonsecurity.com) 28

In July 2015, the marital infidelity website AshleyMadison.com was hacked by a group called the Impact Team, threatening to release data on all 37 million users unless the site shut down. In an article published earlier today, security researcher Brian Krebs explores the possible involvement of a former employee and self-describe expert in search engine optimization (SEO), William Brewster Harrison, who had a history of harassment towards then-CEO Noel Biderman and may have had the technical skills to carry out the hack. However, Harrison committed suicide in 2014, raising doubts about his role in the breach. Here's an excerpt from the report: [...] Does Harrison's untimely death rule him out as a suspect, as his stepmom suggested? This remains an open question. In a parting email to Biderman in late 2012, Harrison signed his real name and said he was leaving, but not going away. "So good luck, I'm sure we'll talk again soon, but for now, I've got better things in the oven," Harrison wrote. "Just remember I outsmarted you last time and I will outsmart you and out maneuver you this time too, by keeping myself far far away from the action and just enjoying the sideline view, cheering for the opposition." Nothing in the leaked Biderman emails suggests that Ashley Madison did much to revamp the security of its computer systems in the wake of Harrison's departure and subsequent campaign of harassment -- apart from removing an administrator account of his a year after he'd already left the company.

KrebsOnSecurity found nothing in Harrison's extensive domain history suggesting he had any real malicious hacking skills. But given the clientele that typically employed his skills -- the adult entertainment industry -- it seems likely Harrison was at least conversant in the dark arts of "Black SEO," which involves using underhanded or else downright illegal methods to game search engine results. Armed with such experience, it would not have been difficult for Harrison to have worked out a way to maintain access to working administrator accounts at Ashley Madison. If that in fact did happen, it would have been trivial for him to sell or give those credentials to someone else. Or to something else. Like Nazi groups. As KrebsOnSecurity reported last year, in the six months leading up to the July 2015 hack, Ashley Madison and Biderman became a frequent subject of derision across multiple neo-Nazi websites.

Some readers have suggested that the data leaked by the Impact Team could have originally been stolen by Harrison. But that timeline does not add up given what we know about the hack. For one thing, the financial transaction records leaked from Ashley Madison show charges up until mid-2015. Also, the final message in the archive of Biderman's stolen emails was dated July 7, 2015 -- almost two weeks before the Impact Team would announce their hack. Whoever hacked Ashley Madison clearly wanted to disrupt the company as a business, and disgrace its CEO as the endgame. The Impact Team's intrusion struck just as Ashley Madison's parent was preparing go public with an initial public offering (IPO) for investors. Also, the hackers stated that while they stole all employee emails, they were only interested in leaking Biderman's. Also, the Impact Team had to know that ALM would never comply with their demands to dismantle Ashley Madison and Established Men. In 2014, ALM reported revenues of $115 million. There was little chance the company was going to shut down some of its biggest money machines. Hence, it appears the Impact Team's goal all along was to create prodigious amounts of drama and tension by announcing the hack of a major cheating website, and then let that drama play out over the next few months as millions of exposed Ashley Madison users freaked out and became the targets of extortion attacks and public shaming.

After the Impact Team released Biderman's email archives, several media outlets pounced on salacious exchanges in those messages as supposed proof he had carried on multiple affairs. Biderman resigned as CEO of Ashley Madison on Aug. 28, 2015. Complicating things further, it appears more than one malicious party may have gained access to Ashley's Madison's network in 2015 or possibly earlier. Cyber intelligence firm Intel 471 recorded a series of posts by a user with the handle "Brutium" on the Russian-language cybercrime forum Antichat between 2014 and 2016. Brutium routinely advertised the sale of large, hacked databases, and on Jan. 24, 2015, this user posted a thread offering to sell data on 32 million Ashley Madison users. However, there is no indication whether anyone purchased the information. Brutium's profile has since been removed from the Antichat forum.
Note: This is Part II of a story published last week on reporting that went into a new Hulu documentary series on the 2015 Ashley Madison hack.

Intel Kills Its NUC Line (pcworld.com) 67

Intel has decided to stop making its Next Unit of Computing (NUC), but the company will encourage partners to keep making the small form-factor (SFF) PCs, the company said Tuesday. From a report: Intel's NUC championed compact PCs, while leaving larger chassis options to partners like Dell and HP. But Intel's decision seems like a natural one, given that Intel has refocused on its core businesses during a period in which it also invested heavily in its own manufacturing operations and foundry business.

An Intel spokesman confirmed an initial report by Serve The Home, saying that Intel will continue to support the existing NUCs it has already shipped into the market. "We have decided to stop direct investment in the Next Unit of Compute (NUC) Business and pivot our strategy to enable our ecosystem partners to continue NUC innovation and growth," the Intel spokesman said in an email.

Why Are There So Many Programming Languages? (acm.org) 160

Long-time Slashdot reader theodp writes: Recalling a past Computer History Museum look at the evolution of programming languages, Doug Meil ponders the age-old question of Why Are There So Many Programming Languages? in a new Communications of the ACM blog post.

"It's worth noting and admiring the audacity of PL/I (1964)," Meil writes, "which was aiming to be that 'one good programming language.' The name says it all: Programming Language 1. There should be no need for 2, 3, or 4. [Meil expands on this thought in Lessons from PL/I: A Most Ambitious Programming Language.] Though PL/I's plans of becoming the Highlander of computer programming didn't play out like the designers intended, they were still pulling on a key thread in software: why so many languages? That question was already being asked as far back as the early 1960's."

One of PL/I's biggest fans was Digital Research Inc. (DRI) founder Gary Kildall, who crafted the PL/I-inspired PL/M (Programming Language for Microcomputers) in 1973 for Intel. But IBM priced PL/I higher than the languages it sought to replace, contributing to PL/I's failure to gain traction. (Along the lines of how IBM's deal with Microsoft gave rise to a price disparity that was the undoing of Kildall's CP/M OS, bundled with every PC in a 'non-royalty' deal. Windows was priced at $40 while CP/M was offered 'a la carte' at $240.) As a comp.lang.pl1 poster explained in 2006, "The truth of the matter is that Gresham's Law: 'Bad money drives out good' or Ruskin's principle: 'The hoi polloi always prefer an inferior, cheap product over a superior, more expensive one' are what govern here."

Inflection AI Develops Supercomputer Equipped With 22,000 Nvidia H100 AI GPUs 28

Inflection AI, an AI startup company, has built a cutting-edge supercomputer equipped with 22,000 NVIDIA H100 GPUs. Wccftech reports: For those unfamiliar with Inflection AI, it is a business that aims at creating "personal AI for everyone." The company is widely known for its recently introduced Inflection-1 AI model, which powers the Pi chatbot. Although the AI model hasn't yet reached the level of ChatGPT or Google's LaMDA models, reports suggest that Inflection-1 performs well on "common sense" tasks, making it much more suitable for applications such as personal assistance.
>
Coming back, Inflection announced that it is building one of the world's largest AI-based supercomputers, and it looks like we finally have a glimpse of what it would be. It is reported that the Inflection supercomputer is equipped with 22,000 H100 GPUs, and based on analysis, it would contain almost 700 four-node racks of Intel Xeon CPUs. The supercomputer will utilize an astounding 31 Mega-Watts of power.

The surprising fact about the supercomputer is the acquisition of 22,000 NVIDIA H100 GPUs. We all are well aware that, in recent times, it has been challenging to acquire even a single unit of the H100s since they are in immense demand, and NVIDIA cannot cope with the influx of orders. In the case of Inflection AI, NVIDIA is considering being an investor in the company, which is why in their case, it is easier to get their hands on such a massive number of GPUs.

Firefox 115 Released (mozilla.org) 61

williamyf writes: Today, Mozilla released Firefox 115. Changes most visible to users include:

* Hardware video decoding is now enabled for Intel GPUs on Linux..

* Migrating from another browser? Now you can bring over payment methods you've saved in Chrome-based browsers to Firefox.

* The Tab Manager dropdown now features close buttons, so you can close tabs more quickly.

* The Firefox for Android address bar's new search button allows you to easily switch between search engines and search your bookmarks and browsing history.

* We've refreshed and streamlined the user interface for importing data in from other browsers.

* Users without platform support for H264 video decoding can now fallback to Cisco's OpenH264 plugin for playback.

But the most important feature is that this release is the new ESR. Why this is important? y'all ask, well:

* Many a "downstream" project depends on Firefox ESR, for example the famous email client Thunderbird, or KaiOS (a mobile OS very popular in India, SE Asia, Africa and LatAm), so, for better or worse, whatever made it to (or is lacking from) this version of the browser, those projects have to use for the next year.

* Firefox ESR is the default browser of many distros, like Debian and Kali Linux, so, whatever made it to this version will be there for next year, ditto to whatever is lacking.

* If you are on old -- unsupported OSs, like Windows 7, 8-8.1 or MacOS 10.14 (Mojave, the last MacOS with support for 32 Bit Apps), 10.13 or 10.12 you will automatically be migrated to Firefox ESR, so this will be your browser until Sept. 2024.

AMD CPU Use Among Linux Gamers Approaching 70% Marketshare (phoronix.com) 127

The June Steam Survey results show that AMD CPUs have gained significant popularity among Linux gamers, with a market share of 67% -- a remarkable 7% increase from the previous month. Phoronix reports: In part that's due to the Steam Deck being powered by an AMD SoC but it's been a trend building for some time of AMD's increasing Ryzen CPU popularity among Linux users to their open-source driver work and continuing to build more good will with the community.

In comparison, last June the AMD CPU Linux gaming marketshare came in at 45% while Intel was at 54%. Or at the start of 2023, AMD CPUs were at a 55% marketshare among Linux gamers. Or if going back six years, AMD CPU use among Linux gamers was a mere 18% during the early Ryzen days. It's also the direct opposite on the Windows side. When looking at the Steam Survey results for June limited to Windows, there Intel has a 68% marketshare to AMD at 32%.

Beyond the Steam Deck, it's looking like AMD's efforts around open-source drivers, AMD expanding their Linux client (Ryzen) development efforts over the past two years, promises around OpenSIL, and other efforts commonly covered on Phoronix are paying off for AMD in wooing over their Linux gaming customer base.

Intel Restructures Manufacturing Business (reuters.com) 8

Intel says its manufacturing business will work like a separate unit and will begin to generate a margin, but gave no clear timeline on when it will start scaling up, sending the chipmaker's shares down about 5%. From a report: The company also did not name a new external customer for the business as part of its foundry services, a key element of Intel's turnaround plans wherein it will offer its manufacturing services to other companies including its competitors. Intel's internal business units will now have a customer-supplier relationship with the manufacturing business, Chief Financial Officer David Zinsner said on an investor call. Based on that model, Intel will be the second largest foundry next year with manufacturing revenue of more than $20 billion, he said.

Intel's New Font For Low-Vision Developers Is Causing Design Drama For Coders (fastcompany.com) 96

Elissaveta M. Brandon writes via Fast Company: There's a new font in town -- and it's already causing rifts on Reddit. The font is called Intel One Mono, and as its name implies, it was designed by tech giant Intel, together with New York-based type design practice Frere-Jones Type and marketing agency VMLY&R. It joins a group of monospaced fonts designed primarily for developers -- think JetBrains Mono, Fira Code, and Consolas. By definition, monospaced fonts consist of characters that have the same width and occupy the same horizontal space, making it easy for coders and programmers to tell the difference between long strings of characters. But here's where Intel One Mono stands out: it was designed with and for low-vision developers. (It's free to download on GitHub and will soon be available on Google Fonts, too.)

To ensure the font was legible and readable to its target audience, the team ran more than a dozen "live testing sessions" with visually impaired developers who were asked to write code using Intel One Mono. [...] Some of the feedback the designers received was particularly surprising. For example, some people were struggling to tell apart a capital "M" from a capital "N," most likely because both letters have two vertical stems and some diagonals in between, which can be confusing. To make the letters more legible, the designers sloped the vertical stems on the "M" so it looks close to an inverted W. "The point at which the two diagonals meet in the middle gets shifted up to make it clearly a V shape in the middle, and then the two verticals get flared out a little bit to give it slightly more differentiable shape from the capital N," says Fred Shallcrass, a type designer at Frere-Jones Type.

Similar challenges kept coming back with the "x" and the "y" which people struggled to distinguish, and the "e" and the "c." In every instance, the designers meticulously tweaked the letters to make them highly distinctive, resulting in a fairly idiosyncratic font where every glyph is as different as possible from the other -- all the way down to the curly brackets, which can best be described as extra curly. This brings us to that Reddit rift. "This font would be great were it not for those curly braces," one person wrote. "For someone that hates fonts sometimes because of curly brackets not being clear and evident, I'm officially switching to this font set because of the curly brackets," wrote another. The developers were equally torn, but the designers stand by them.
"Part of our thinking in negotiating those responses is that reinforcing the identity of any shape is not just amplifying what is unique about that letter, but also making it clearly not some other letter, so foreclosing any confusion," says Tobias Frere-Jones, the founder and lead designer at his eponymous studio. "If there's a thing the curly braces do, which is that extra back and forth movement, the parentheses don't do that, the brackets don't do that, therefore these ought to do a lot of that."

Google's New Standard For ChromeOS: 'Chromebook X' (9to5google.com) 27

Google is launching the "Chromebook X" program, aiming to differentiate high-quality laptops and tablets from standard Chromebooks by improving hardware specifications and adding exclusive features such as enhanced video conferencing capabilities and unique wallpapers. Chromebook X devices, expected to be priced between $350 and $500, will provide users with an elevated experience beyond the basic functionality of traditional Chromebooks. The devices are anticipated to be available in stores by the end of the year, coinciding with the release of ChromeOS version 115 or newer. 9to5Google reports: For the past few months, Google has been preparing new branding for above average devices from various Chromebook makers. Notably, we haven't yet seen any signs of Google making a Chromebook X device of its own, which is honestly a shame considering how long it's been since a Pixelbook has been released. The Chromebook X brand, which could change before launch, will appear somewhere on a laptop/tablet's chassis, with a mark that could be as simple as an "X" next to the usual "Chromebook" logo. There should also be a special boot screen instead of the standard "chromeOS" logo that's shown on all machines today.

Aside from the added "X," what actually sets a Chromebook X apart from other devices is the hardware inside. Specifically, Google appears to require a certain amount of RAM, a good-quality camera for video conferencing, and a (presumably) higher-end display. Beyond that, Google has so far made specific preparations for Chromebook X models to be built on four types of processors from Intel and AMD (though newer generations will likely also be included): AMD Zen 2+ (Skyrim), AMD Zen 3 (Guybrush), and Intel Core 12th Gen (Brya & Nissa).

To further differentiate Chromebook X models from low-end Chromebooks, Google is also preparing an exclusive set of features. As mentioned, one of the key focuses of Chromebook X is video conferencing, with Google requiring an up-to-spec camera. Complementing that hardware, Google is bringing unique features like Live Caption (adding generated captions to video calls), a built-in portrait blur effect, and "voice isolation." Earlier this year, we reported that ChromeOS was readying a set of "Time Of Day" wallpapers and screen savers that would change in appearance throughout the day, particularly to match the sunrise and sunset. We now know that these are going to be exclusive to Chromebook X devices. To ensure that those wallpapers only appear on Chromebook X and can't be forcibly enabled, Google is preparing a system it calls "feature management." At the moment, feature management is only used to check whether to enable Chromebook X exclusives. Based on that, some other exclusive features of Chromebook X include: Support for up to 16 virtual desks; "Pinned" (available offline) files from Google Drive; and A revamped retail demo mode.

Latest SUSE Linux Enterprise Goes All in With Confidential Computing 7

SUSE's latest release of SUSE Linux Enterprise 15 Service Pack 5 (SLE 15 SP5) has a focus on security, claiming it as the first distro to offer full support for confidential computing to protect data. From a report: According to SUSE, the latest version of its enterprise platform is designed to deliver high-performance computing capabilities, with an inevitable mention of AI/ML workloads, plus it claims to have extended its live-patching capabilities. The release also comes just weeks after the community release openSUSE Leap 15.5 was made available, with the two sharing a common core. The Reg's resident open source guru noted that Leap 15.6 has now been confirmed as under development, which implies that a future SLE 15 SP6 should also be in the pipeline.

SUSE announced the latest version at its SUSECON event in Munich, along with a new report on cloud security issues claiming that more than 88 percent of IT teams have reported at least one cloud security incident over the the past year. This appears to be the justification for the claim that SLE 15 SP5 is the first Linux distro to support "the entire spectrum" of confidential computing, allowing customers to run fully encrypted virtual machines on their infrastructure to protect applications and their associated data. Confidential computing relies on hardware-based security mechanisms in the processor to provide this protection, so enterprises hoping to take advantage of this will need to ensure their servers have the necessary support, such as AMD's Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP) and Intel's Trust Domain Extensions (TDX).

Intel To Invest $25 Billion In Israel Factory In Record Deal, Netanyahu Says (reuters.com) 42

An anonymous reader quotes a report from Reuters: U.S. chipmaker Intel will spend $25 billion on a new factory in Israel, Prime Minister Benjamin Netanyahu said on Sunday, calling it the largest-ever international investment in the country. The factory in Kiryat Gat is due to open in 2027, to operate through 2035 at least and to employ thousands of people, Israel's Finance Ministry said. Under the deal Intel will pay a 7.5% tax rate, up from the current 5%, the ministry added.

During its almost five decades of operations in Israel, Intel has grown to become the country's largest privately held employer and exporter and a leader of the local electronics and information industry, according to the company's website. In 2017, Intel bought Israel-based Mobileye, which develops and deploys advanced driver-assistance systems, for $15 billion. Intel took Mobileye public last year.

Intel To Spend $33 Billion in Germany in Landmark Expansion (reuters.com) 12

Intel will invest more than 30 billion euros ($33 billion) in Germany as part of its expansion push in Europe, the U.S. company said on Monday, marking the biggest investment by a foreign company in Europe's top economy. From a report: The deal to build two leading-edge semiconductor facilities in the eastern city of Magdeburg involves 10 billion euros in German subsidies, a person familiar with the matter said. Intel CEO Pat Gelsinger said he was grateful to the German government and the state of Saxony-Anhalt, where Magdeburg is located, for "fulfilling the vision of a vibrant, sustainable, leading-edge semiconductor industry in Germany and the EU." Under Gelsinger, Intel has been investing billions in building factories across three continents to restore its dominance in chipmaking and better compete with rivals AMD, Nvidia and Samsung.

Dev Boots Linux 292,612 Times to Find Kernel Bug (tomshardware.com) 32

Long-time Slashdot reader waspleg shared this story from Hot Hardware: Red Hat Linux developer Richard WM Jones has shared an eyebrow raising tale of Linux bug hunting. Jones noticed that Linux 6.4 has a bug which means it will hang on boot about 1 in 1,000 times. Jones set out to pinpoint the bug, and prove he had caught it red handed. However, his headlining travail, involving booting Linux 292,612 times (and another 1,000 times to confirm the bug) apparently "only took 21 hours." It also seems that the bug is less common with Intel hardware than AMD based machines.

Intel To Start Shipping a Quantum Processor (arstechnica.com) 18

An anonymous reader quotes a report from Ars Technica: Intel does a lot of things, but it's mostly noted for making and shipping a lot of processors, many of which have been named after bodies of water. So, saying that the company is set to start sending out a processor called Tunnel Falls would seem unsurprising if it weren't for some key details. Among them: The processor's functional units are qubits, and you shouldn't expect to be able to pick one up on New Egg. Ever. Tunnel Falls appears to be named after a waterfall near Intel's Oregon facility, where the company's quantum research team does much of its work. It's a 12-qubit chip, which places it well behind the qubit count of many of Intel's competitors -- all of which are making processors available via cloud services. But Jim Clarke, who heads Intel's quantum efforts, said these differences were due to the company's distinct approach to developing quantum computers.

Intel, in contrast, is attempting to build silicon-based qubits that can benefit from the developments that most of the rest of the company is working on. The company hopes to "ride the coattails of what the CMOS industry has been doing for years," Clarke said in a call with the press and analysts. The goal, according to Clarke, is to make sure the answer to "what do we have to change from our silicon chip in order to make it?" is "as little as possible." The qubits are based on quantum dots, structures that are smaller than the wavelength of an electron in the material. Quantum dots can be used to trap individual electrons, and the properties of the electron can then be addressed to store quantum information. Intel uses its fabrication expertise to craft the quantum dot and create all the neighboring features needed to set and read its state and perform manipulations.

However, Clarke said there are different ways of encoding a qubit in a quantum dot (Loss-DiVincenzo, singlet-triplet, and exchange-only, for those curious). This gets at another key difference with Intel's efforts: While most of its competitors are focused solely on fostering a software developer community, Intel is simultaneously trying to develop a community that will help it improve its hardware. (For software developers, the company also released a software developer kit.) To help get this community going, Intel will send Tunnel Falls processors out to a few universities: The Universities of Maryland, Rochester, Wisconsin, and Sandia National Lab will be the first to receive the new chip, and the company is interested in signing up others. The hope is that researchers at these sites will help Intel characterize sources of error and which forms of qubits provide the best performance.
"Overall, Intel has made a daring choice for its quantum strategy," concludes Ars' John Timmer. "Electron-based qubits have been more difficult to work with than many other technologies because they tend to have shorter life spans before they decohere and lose the information they should be holding. Intel is counting on rapid iteration, a large manufacturing capacity, and a large community to help it figure out how to overcome this. But testing quantum computing chips and understanding why their qubits sometimes go wrong is not an easy process; it requires highly specialized refrigeration hardware that takes roughly a day to get the chips down to a temperature where they can be used."

"The company seems to be doing what it needs to overcome that bottleneck, but it's likely to need more than three universities to sign up if the strategy is going to work."

Intel To Launch New Core Processor Branding for Meteor Lake: Drop the i, Add Ultra Tier (anandtech.com) 36

As first hinted at by Intel back in late April, Intel is embarking on a journey to redefine its client processor branding, the biggest such shift in the previous 15 years of the company. From a report: Having already made waves by altering its retail packaging on premium desktop chips such as the Core i9-11900K and Core i9-12900K, the tech giant aims to introduce a new naming scheme across its client processors, signaling a transformative phase in its client roadmap. This shift is due to begin in the second half of the year, when Intel will launch their highly anticipated Meteor Lake CPUs. Meteor Lake represents a significant leap forward for the company in regards to manufacturing, architecture, and design -- and, it would seem, is prompting the need for a fresh product naming convention.

The most important changes include dropping the 'i' from the naming scheme and opting for a more straightforward Core 3, 5, and 7 branding structure for Intel's mainstream processors. The other notable inclusion, which is now officially confirmed, is that Intel will bifurcate the Core brand a bit and place its premium client products in their own category, using the new Ultra moniker. Ultra chips will signify a higher performance tier and target market for the parts, and will be the only place Intel uses their top-end Core 9 (previously i9) branding.

Hackers Can Steal Cryptographic Keys By Video-Recording Power LEDs 60 Feet Away (arstechnica.com) 26

An anonymous reader quotes a report from Ars Technica: Researchers have devised a novel attack that recovers the secret encryption keys stored in smart cards and smartphones by using cameras in iPhones or commercial surveillance systems to video record power LEDs that show when the card reader or smartphone is turned on. The attacks enable a new way to exploit two previously disclosed side channels, a class of attack that measures physical effects that leak from a device as it performs a cryptographic operation. By carefully monitoring characteristics such as power consumption, sound, electromagnetic emissions, or the amount of time it takes for an operation to occur, attackers can assemble enough information to recover secret keys that underpin the security and confidentiality of a cryptographic algorithm. [...]

On Tuesday, academic researchers unveiled new research demonstrating attacks that provide a novel way to exploit these types of side channels. The first attack uses an Internet-connected surveillance camera to take a high-speed video of the power LED on a smart card reader -- or of an attached peripheral device -- during cryptographic operations. This technique allowed the researchers to pull a 256-bit ECDSA key off the same government-approved smart card used in Minerva. The other allowed the researchers to recover the private SIKE key of a Samsung Galaxy S8 phone by training the camera of an iPhone 13 on the power LED of a USB speaker connected to the handset, in a similar way to how Hertzbleed pulled SIKE keys off Intel and AMD CPUs. Power LEDs are designed to indicate when a device is turned on. They typically cast a blue or violet light that varies in brightness and color depending on the power consumption of the device they are connected to.

There are limitations to both attacks that make them unfeasible in many (but not all) real-world scenarios (more on that later). Despite this, the published research is groundbreaking because it provides an entirely new way to facilitate side-channel attacks. Not only that, but the new method removes the biggest barrier holding back previously existing methods from exploiting side channels: the need to have instruments such as an oscilloscope, electric probes, or other objects touching or being in proximity to the device being attacked. In Minerva's case, the device hosting the smart card reader had to be compromised for researchers to collect precise-enough measurements. Hertzbleed, by contrast, didn't rely on a compromised device but instead took 18 days of constant interaction with the vulnerable device to recover the private SIKE key. To attack many other side channels, such as the one in the World War II encrypted teletype terminal, attackers must have specialized and often expensive instruments attached or near the targeted device. The video-based attacks presented on Tuesday reduce or completely eliminate such requirements. All that's required to steal the private key stored on the smart card is an Internet-connected surveillance camera that can be as far as 62 feet away from the targeted reader. The side-channel attack on the Samsung Galaxy handset can be performed by an iPhone 13 camera that's already present in the same room.
Videos here and here show the video-capture process of a smart card reader and a Samsung Galaxy phone, respectively, as they perform cryptographic operations. "To the naked eye, the captured video looks unremarkable," adds Ars.

"But by analyzing the video frames for different RGB values in the green channel, an attacker can identify the start and finish of a cryptographic operation."

AMD Likely To Offer Details on AI Chip in Challenge To Nvidia (reuters.com) 18

Advanced Micro Devices on Tuesday is expected to reveal new details about an AI "superchip" that analysts believe will be a strong challenger to Nvidia, whose chips dominate the fast-growing artificial intelligence market. From a report: AMD Chief Executive Lisa Su will give a keynote address at an event in San Francisco on the company's strategy in the data center and AI markets. Analysts expect fresh details about a chip called the MI300, AMD's most advanced graphics processing unit, the category of chips that companies like OpenAI use to develop products such as ChatGPT. Nvidia dominates the AI computing market with 80% to 95% of market share, according to analysts.

Last month, Nvidia's market capitalization briefly touched $1 trillion after the company said it expected a jump in revenue after it secured new chip supplies to meet surging demand. Nvidia has few competitors working at a large scale. While Intel and several startups such as Cerebras Systems and SambaNova Systems have competing products, Nvidia's biggest sales threat so far is the internal chip efforts at Alphabet's Google and Amazon's cloud unit, both of which rent their custom chips to outside developers.

Will Submerging Computers Make Data Centers More Climate Friendly? (oregonlive.com) 138

20 miles west of Portland, engineers at an Intel lab are dunking expensive racks of servers "in a clear bath" made of motor oil-like petrochemicals, reports the Oregonian, where the servers "give off a greenish glow as they silently labor away on ordinary computing tasks." Intel's submerged computers operate just as they would on a dry server rack because they're not bathing in water, even though it looks just like it. They're soaking in a synthetic oil that doesn't conduct electricity. So the computers don't short out.

They thrive, in fact, because the fluid absorbs the heat from the hardworking computers much better than air does. It's the same reason a hot pan cools off a lot more quickly if you soak it in water than if you leave it on the stove.

As data centers grow increasingly powerful, the computers are generating so much heat that cooling them uses exorbitant amounts of energy. The cooling systems can use as much electricity as the computers themselves. So Intel and other big tech companies are designing liquid cooling systems that could use far less electricity, hoping to lower data centers' energy costs by as much as a third — and reducing the facilities' climate impact. It's a wholesale change in thinking for data centers, which already account for 2% of all the electricity consumption in the U.S... Skeptics caution that it may be difficult or prohibitively expensive to overhaul existing data centers to adapt to liquid cooling. Advocates of the shift, including Intel, say a transition is imperative to accommodate data centers' growing thirst for power. "It's really starting to come to a head as we're hitting the energy crisis and the need for climate action globally," said Jen Huffstetler, Intel's chief product sustainability officer...

Cooler computers can be packed more tightly together in data centers, since they don't need space for airflow. Computer manufacturers can pack chips together more tightly on the motherboard, enabling more computing power in the same space. And liquid cooling could significantly reduce data centers' environmental and economic costs. Conventional data centers' evaporative cooling systems require tremendous volumes of water and huge amounts of electricity...

Many other tech companies are backing immersion cooling, too. Google, Facebook and Microsoft are all helping fund immersion cooling research at Oregon State... [T]he timing may finally be right for data centers operators to make the shift away from air cooling to something far more efficient. Intel's Huffstetler said she expects to see liquid cooling become widespread in the next three to five years.

The article notes other challenges:
  • liquid adds more weight than some buildings' upper floors can support
  • Some metals degrade faster in liquid than they do in air.
  • And the engineers had to modify the servers by removing their fans — "because they serve no purpose while immersed."
