Google and iFixit are expanding their partnership by offering several original parts for the Pixel tablet that Google had released in June. Google first partnered with iFixit in early 2022 to sell official replacement parts for its Pixel phones. Engadget reports: One of the most expensive components now available for sale is the tablet's rear case, which costs $200 and comes with three microphones, antennas, a power button with fingerprint unlock and volume controls. If your tablet's battery gets busted, you can now purchase an authentic replacement for $67, while a rear facing camera to replace one that's having issues will set you back $25. One replacement speaker will also cost you $25, as will a replacement for the device's USB-C port. But if it's the tablet's screen that needs replacing, you'll have to pay $200 or more. You can either get the part only -- consisting of a front glass digitizer screen, a 10.95-inch 2560 x 1600 pixel LCD and an 8-megapixel front-facing camera -- for that price or get a pack with tools you'll need to open up the tablet for $6 more.

iFixit, of course, doesn't just sell the parts: Its Pixel tablet portal also contains guides on how you can repair the model for each component it's selling. You can follow them if you want to be sure you're doing the right thing, even if you're pretty good at tinkering with electronics.

Google is working to push back the expiration date of Chromebooks, addressing concerns held by school administrators that the laptops are too short-lived to be cost effective. From a report: The Alphabet-owned company -- which develops the Chrome operating system running on computers made mostly by others -- said Thursday it plans to provide software updates for Chromebooks for up to a decade. The new policy, which starts next year, ensures that no existing Chromebook will expire within the next two years. The disclosure of this policy change comes after an August column in The Wall Street Journal detailing schools' struggles with expiring Chromebooks. Chromebooks are ubiquitous in classrooms around the country, but some education software doesn't work after what Google calls the Auto Update Expiration date. Unsupported Chromebooks can't be used for mandatory state testing, even if the hardware still appears functional.

When the laptops expire, school districts recycle them, sometimes at a cost, and spend millions of dollars on replacements. Google currently sets expiration dates based on the release date of specific models. Newer models have eight years of support, while older Chromebooks have five. Starting in 2024, Google will support a given laptop "platform" -- a certain combination of hardware components -- for 10 years after the first device in the platform hits store shelves. These so-called platforms aren't unique to specific brands or manufacturers and can be found in a variety of distinct models.

Huawei's launch last week of the Mate 60 Pro smartphone "shocked industry experts," reports CNN, who didn't understand how Huawei "would have the ability to manufacture such an advanced smartphone following sweeping efforts by the United States to restrict China's access to foreign chip technology."

And in a related note, CNN adds that South Korean chipmaker SK Hynix "is investigating how two of its memory chips mysteriously ended up inside the Mate 60 Pro, a controversial smartphone launched by Huawei last week." Shares in Hynix fell more than 4% on Friday after it emerged that two of its products, a 12 gigabyte (GB) LPDDR5 chip and 512 GB NAND flash memory chip, were found inside the Huawei handset by TechInsights, a research organization based in Canada specializing in semiconductors, which took the phone apart for analysis. "The significance of the development is that there are restrictions on what SK Hynix can ship to China," G Dan Hutcheson, vice chair of TechInsights, told CNN. "Where do these chips come from? The big question is whether any laws were violated."

A Hynix spokesperson told CNN Friday that it was aware of its chips being used in the Huawei phone and had started investigating the issue.

The company "no longer does business with Huawei since the introduction of the U.S. restrictions against the company," it said in a statement... Industry insiders said it was possible that Huawei had purchased the memory chips from the secondary market and not directly from the manufacturer. It's also possible Huawei may have had a stockpile of components accumulated before the U.S. export curbs kicked in fully.

According to Android specialist Mishaal Rahman, Android miscalculates the storage space taken up by system components, leading to inflated system storage utilization and potentially misleading users. Chandraveer Mathur writes via Android Police. From the report: We usually rely on Android's storage utilization utility to find apps and files eating up storage space, so we can uninstall or delete them if required. However, Android specialist Mishaal Rahman discovered that Google's calculation of the space consumed by Android system components is flawed. He executed shell commands to create a 3GB file in the /data/media/0 storage directory, which isn't a file path used for Android system files. However, the phone's storage breakdown showed a marked 3GB increase under the System heading, suggesting the OS suddenly became bigger.

This happens because Android calculates system storage as the space used up by anything other than what's covered by other categories in the storage breakdown, including audios, videos, images, documents, trash, and games. This means the System heading in the break doesn't just include Android system files. Android 14 also uses this dangerously flawed logic for calculating storage usage. Moreover, the Files app by Google also shows similar storage utilization by Android system components, perhaps because it uses the same incredulous attribution logic. By association, all other Android skins use flawed calculation of used storage space, but Samsung reportedly fixed this issue with the One UI 6 update. After running similar ADB commands as in the previous experiment, Rahman could confirm the increased utilization showed up under the Other files heading in the storage breakdown, instead of the System heading.

Siddharth Vikram Philip, Sabah Meddings, and Supriya Singh, reporting for Bloomberg News: As chief commercial officer of aircraft-parts supplier AOG Technics, Ray Kwong can look back on a well-rounded career at A-list companies including All Nippon Airways, Mitsubishi Heavy Industries and Nissan Motor. That, at least, is Kwong's two-decade corporate journey on what appears to be his LinkedIn profile, from which the self-proclaimed executive beams with a broad smile and striped tie in blue hues. Trouble is that -- much like the company for which Kwong now claims to work -- not all is as it seems. Kwong, if he even exists, was never employed at Nissan, or at ANA for that matter. Neither company has records of him as a former worker, they said in response to queries by Bloomberg News. His employment history could also not be verified at Mitsubishi. What is used as his profile picture turns out to be a stock photo that's also washed up elsewhere on the Internet, from promotional material for a German textile startup to a clinic in Northbrook, Illinois.

After Bloomberg reported on the case of bogus jet-engine repair parts being investigated by regulators, a deeper dive into AOG revealed that the fabrication not only concerned components, but extended to major aspects of the company behind the scandal. The proliferation of undocumented parts has sent shock waves through an industry where every component requires verification to ensure aircraft safety, leaving manufacturers, operators and authorities scrambling to determine the fallout. The parts supplied by AOG went into engines that power many older-generation Airbus SE A320 and Boeing 737 planes, by far the most widely flown category of commercial aircraft. These single-aisle jets are used by millions of passengers each day and by most airlines, mainly on short-haul flights. Airbus said it's aware of media reports surrounding AOG, while Boeing said it will defer to regulators on the topic.

Microsoft will finally stop forcing Windows 11 users in Europe into Edge if they click a link from the Windows Widgets panel or from search results. From a report: The software giant has started testing the changes to Windows 11 in recent test builds of the operating system, but the changes are restricted to countries within the European Economic Area (EEA). "In the European Economic Area (EEA), Windows system components use the default browser to open links," reads a change note from a Windows 11 test build released to Dev Channel testers last month. Microsoft has been ignoring default browser choices in its search experience in Windows 10 and the taskbar widget that forces users into Edge if they click a link instead of their default browser. Windows 11 continued this trend, with search still forcing users into Edge and a new dedicated widgets area that also ignores the default browser setting.

Apple is developing a low-cost MacBook series to compete with Chromebook models in the education sector that could be launched as early as the second half of 2024, claims a new report out of Taiwan. From a report: According to DigiTimes' industry sources, Apple will likely launch the new product line to differentiate it from the company's existing MacBook Air and Pro lines. The outer appearance will still use a metal casing but will be made of "different materials" and the cost of the mechanical components will be lower, claims the report. The launch timeframe for the alleged new MacBook series appears to be based on a lack of related activity at major Apple suppliers like Quanta Computer and Foxconn, making a launch in the first half of next year unlikely.

Vanity Fair revisits the many warning signs about OceanGate's Titan submersible prior to an implosion on June 18th that killed all five passengers onboard.

A professional expedition leader tells their reporter that "This tragedy was predicted. It was avoidable. It was inevitable." As the world now knows, Stockton Rush touted himself as a maverick, a disrupter, a breaker of rules. So far out on the visionary curve that, for him, safety regulations were mere suggestions. "If you're not breaking things, you're not innovating," he declared at the 2022 GeekWire Summit. "If you're operating within a known environment, as most submersible manufacturers do, they don't break things. To me, the more stuff you've broken, the more innovative you've been." In a culture that has adopted the ridiculous mantra "move fast and break things," that type of arrogance can get a person far. But in the deep ocean, the price of admission is humility — and it's nonnegotiable...

In December 2015, two years before the Titan was built, Rush had lowered a one third scale model of his 4,000-meter-sub-to-be into a pressure chamber and watched it implode at 4,000 psi, a pressure equivalent to only 2,740 meters. The test's stated goal was to "validate that the pressure vessel design is capable of withstanding an external pressure of 6,000 psi — corresponding to...a depth of about 4,200 meters." He might have changed course then, stood back for a moment and reconsidered. But he didn't. Instead, OceanGate issued a press release stating that the test had been a resounding success because it "demonstrates that the benefits of carbon fiber are real."
OceanGate's director of marine operations later issued a Quality Control Inspection Report filled with warnings: These included missing bolts and improperly secured batteries, components zip-tied to the outside of the sub. O-ring grooves were machined incorrectly (which could allow water ingress), seals were loose, a highly flammable, petroleum-based material lined the Titan's interior... Yet even those deficiencies paled in comparison to what Lochridge observed on the hull. The carbon fiber filament was visibly coming apart, riddled with air gaps, delaminations, and Swiss cheese holes — and there was no way to fix that short of tossing the hull in a dumpster...

Rush's response was to fire Lochridge immediately, serve him and his wife with a lawsuit (although Carole Lochridge didn't work at OceanGate or even in the submersible industry) for breach of contract, fraud, unjust enrichment, and misappropriation of trade secrets; threaten their immigration status; and seek to have them pay OceanGate's legal fees.
The article also tells a story about OceanGate's 240-foot dive to the wreck of the Andrea Doria in 2016. The article claims that Rush disregarded safety instructions, then "landed too close, got tangled in the current, managed to wedge the sub beneath the Andrea Doria's crumbling bow, and descended into a full-blown panic..."

The article's author marvels that five years ago, "I didn't yet know how reckless, how heedless, how insane the Titan was." They'd once even considered booking a trip on the OceanGate's submersible — until receiving this advice from the chief pilot of the University of Hawaii's two deep-sea submarines. "Do not get into that sub. He is going to have a major accident."

An anonymous reader quotes a report from Ars Technica: Russia's military intelligence unit has been targeting Ukrainian Android devices with "Infamous Chisel," the tracking name for new malware that's designed to backdoor devices and steal critical information, Western intelligence agencies said on Thursday. "Infamous Chisel is a collection of components which enable persistent access to an infected Android device over the Tor network, and which periodically collates and exfiltrates victim information from compromised devices," intelligence officials from the UK, US, Canada, Australia, and New Zealand wrote (PDF). "The information exfiltrated is a combination of system device information, commercial application information and applications specific to the Ukrainian military."

Infamous Chisel gains persistence by replacing the legitimate system component known as netd with a malicious version. Besides allowing Infamous Chisel to run each time a device is restarted, the malicious netd is also the main engine for the malware. It uses shell scripts and commands to collate and collect device information and also searches directories for files that have a predefined set of extensions. Depending on where on the infected device a collected file is located, netd sends it to Russian servers either immediately or once a day. When exfiltrating files of interest, Infamous Chisel uses the TLS protocol and a hard-coded IP and port. Use of the local IP address is likely a mechanism to relay the network traffic over a VPN or other secure channel configured on the infected device. This would allow the exfiltration traffic to blend in with expected encrypted network traffic. In the event a connection to the local IP and port fails, the malware falls back to a hard-coded domain that's resolved using a request to dns.google.

Infamous Chisel also installs a version of the Dropbear SSH client that can be used to remotely access a device. The version installed has authentication mechanisms that have been modified from the original version to change the way users log in to an SSH session. [...] The report didn't say how the malware gets installed. In the advisory Ukraine's security service issued earlier this month (PDF), officials said that Russian personnel had "captured Ukrainian tablets on the battlefield, pursuing the aim to spread malware and abuse available access to penetrate the system." It's unclear if this was the vector.

According to Bloombeg's Mark Gurman (paywalled), Apple is experimenting with a new 3D-printing manufacturing process for some device production, starting with the upcoming Apple Watch Series 9 models. MacRumors reports: The new manufacturing process that Apple is testing would use less material than the large slabs of metal that are needed for traditional CNC manufacturing, plus it would cut down on the time that it takes to make new devices. With a technique called "binder jetting," Apple is able to print a device's outline at close to its actual shape using a powdered substance. A second process uses heat and pressure to squeeze the material into a substance that feels like steel, and it is then refined with milling.

Gurman's information echoes what we've already heard from Apple analyst Ming-Chi Kuo. Back in July, Kuo said that the upcoming second-generation Apple Watch Ultra will include 3D printed mechanical parts. Specifically, he claimed that Apple is "actively adopting 3D printing technology," and that some of the titanium components in the new Apple Watch Ultra would be 3D printed. Gurman claims that Apple plans to use this new 3D printing method for the chassis of the stainless steel Apple Watch Series 9 models rather than components for the Ultra but either way, it sounds like Apple is more actively testing this manufacturing method as of 2023. Gurman says that Apple plans to 3D print titanium devices in 2024. The report notes that the shift to 3D printing would also "allow Apple to improve manufacturing times and potentially cut down on costs."

Once tooth decay has set in, all a dentist can do is fill the gap with an artificial plug -- a filling. But in a paper published in Cell, Hannele Ruohola-Baker, a stem-cell biologist at the University of Washington, and her colleagues offer a possible alternative. Economist: Stem cells are those that have the capacity to turn themselves into any other type of cell in the body. It may soon be possible, the researchers argue, to use those protean cells to regrow a tooth's enamel naturally. The first step was to work out exactly how enamel is produced. That is tricky, because enamel-making cells, known as ameloblasts, disappear soon after a person's adult teeth have finished growing. To get round that problem, the researchers turned to samples of tissue from human foetuses that had been aborted, either medically or naturally. Such tissues contain plenty of functioning ameloblasts. The researchers then checked to see which genes were especially active in the enamel-producing cells. Tooth enamel is made mostly of calcium phosphate, and genes that code for proteins designed to bind to calcium were particularly busy. They also assessed another type of cell called odontoblasts. These express genes that produce dentine, another type of hard tissue that lies beneath the outer enamel. Armed with that information, Dr Ruohola-Baker and her colleagues next checked to see whether the stem cells could be persuaded to transform into ameloblasts.

The team devised a cocktail of drugs designed to activate the genes that they knew were expressed in functioning ameloblasts. That did the trick, with the engineered ameloblasts turning out the same proteins as the natural sort. A different cocktail pushed the stem cells to become odontoblasts instead. Culturing the cells together produced what researchers call an organoid -- a glob of tissue in a petri dish which mimics a biological organ. The organoids happily churned out the chemical components of enamel. Having both cell types seemed to be crucial: when odontoblasts were present alongside ameloblasts, genes coding for enamel proteins were more strongly expressed than with ameloblasts alone. For now, the work is more a proof of concept than a prototype of an imminent medical treatment. The next step, says Dr Ruohola-Baker, is to try to boost enamel production even further, with a view to eventually beginning clinical trials. The hope is that, one day, medical versions of the team's organoids could be used as biological implants, to regenerate a patient's decayed teeth.

The UK government will spend $127m to try to win a toe-hold for the nation in the global race to produce computer chips used to power artificial intelligence. From a report: Taxpayer money will be used as part of a drive to build a national AI resource in Britain, similar to those under development in the US and elsewhere. It is understood that the funds will be used to order key components from major chipmakers Nvidia, AMD and Intel. But an official briefed on the plans told the Guardian that the $127m offered by the government is far too low relative to investment by peers in the EU, US and China. The official confirmed, in a move first reported by the Telegraph, which also revealed the investment, that the government is in advanced stages of an order of up to 5,000 graphics processing units (GPUs) from Nvidia. The company, which started out building processing capacity for computer games, has seen a sharp increase in its value as the AI race has heated up. Its chips can run language learning models such as ChatGPT.

Apple has joined a coalition of U.S. businesses in protest at India's sudden introduction of tech import restrictions last month, claiming the move will damage New Delhi's ambitions to become a global manufacturing hub and harm consumers. From a report: n a letter sent to U.S. officials this week, eight American trade groups asked the government to urge India to reconsider the policy, which will see the country impose a new license requirement for technology imports from November 1, covering everything from laptops and tablets to servers and datacenter components. India didn't give a reason for the change in rules, but the move is thought to be an effort to boost local manufacturing, forming another prong in Prime Minister Narendra Modi's "Made in India" campaign to encourage domestic manufacturing in the tech sector.

Bambu's X1C and P1P 3D printers started printing unattended, overnight, and without any additional user input, according to user reports from r/BambuLab and X. The Verge reports: Some woke up to failed prints. Some found a second copy of a previous print. And at least a few found their Bambu X1C or P1P had started smacking itself apart -- damaging components -- while trying to print a second copy atop the object they'd actually asked for. What happened? In an official blog post, Bambu says it's still investigating but suspects that a cloud outage is to blame. The company says its servers had two brief outages on Tuesday morning where the servers couldn't confirm that the printers had actually printed -- but instead of failing gracefully, they wound up sending the same print job again and again until it went through, Bambu's staff believes. "Simply explained, the print job sent to the printer before was trapped on the cloud and had a delayed start," writes Bambu.

When contacted by The Verge, Bambu would not go quite so far as to promise free repairs and replacements for all affected customers but says anyone who's suffered any damage should reach out to Bambu support ASAP. "For damage caused by this incident, we will offer the necessary solutions to our customers impacted by the Cloud Outage, in the form of part replacements or a printer replacement if the situation demands it," spokesperson Taylor Liu tells me.

An anonymous reader quotes a report from The Register: Microsoft prohibits users from reverse engineering or harvesting data from its AI software to train or improve other models, and will store inputs passed into its products as well as any output generated. The details emerged as companies face fresh challenges with the rise of generative AI. People want to know what corporations are doing with information provided by users. And users are likewise curious about what they can do with the content generated by AI. Microsoft addresses these issues in a new clause titled 'AI Services' in its terms of service.

The five new policies, which were introduced on 30 July and will come into effect on September 30, state that:

Reverse Engineering. You may not use the AI services to discover any underlying components of the models, algorithms, and systems. For example, you may not try to determine and remove the weights of models.
Extracting Data. Unless explicitly permitted, you may not use web scraping, web harvesting, or web data extraction methods to extract data from the AI services.
Limits on use of data from the AI Services. You may not use the AI services, or data from the AI services, to create, train, or improve (directly or indirectly) any other AI service.
Use of Your Content. As part of providing the AI services, Microsoft will process and store your inputs to the service as well as output from the service, for purposes of monitoring for and preventing abusive or harmful uses or outputs of the service.
Third party claims. You are solely responsible for responding to any third-party claims regarding Your use of the AI services in compliance with applicable laws (including, but not limited to, copyright infringement or other claims relating to content output during Your use of the AI services). A spokesperson from Microsoft declined to comment on how long the company plans to store user inputs into its software. "We regularly update our terms of service to better reflect our products and services. Our most recent update to the Microsoft Services Agreement includes the addition of language to reflect artificial intelligence in our services and its appropriate use by customers," the representative told us in a statement.

Microsoft has previously said, however, that it doesn't save conversations or use that data to train its AI models for its Bing Enterprise Chat mode. The policies are a little murkier for its Microsoft 365 Copilot, although it doesn't appear to use customer data or prompts for training, it does store information. "[Copilot] can generate responses anchored in the customer's business content, such as user documents, emails, calendar, chats, meetings, contacts, and other business data. Copilot combines this content with the user's working context, such as the meeting a user is in now, the email exchanges the user has had on a topic, or the chat conversations the user had last week. Copilot uses this combination of content and context to help deliver accurate, relevant, contextual responses," it said.

An anonymous reader quotes a report from ZDNet: First shown off at 2022 CES, the Masonite M-PWR comes with a built-in Ring video doorbell and Yale smart lock, plus motion-activated LED lights and a door sensor -- all powered by your home's electrical system so there are no batteries to replace. An onboard battery backup keeps the door operational for 24 hours in the event of a power loss. Both doorbell and lock components can be upgraded over time as technology advances. If you were hoping for an all-in-one app, however, you'll be disappointed. To use all the door's features, you need the Yale app, the Ring app, and the M-PWR app.

What's all this technology going to cost you? The fiberglass Masonite M-PWR starts at $4,000 -- and that's for the basic model. Several finishes/designs/glass options are available, with pricing on the higher-end versions reaching $7,000. If you consider that a decent front door, Ring doorbell, and Yale smart lock from the same retailer can be had for under $1,000, this is clearly a door for people who want the finer things. And that price doesn't include installation, something most homeowners can't do on their own as the door needs to be hard-wired. The door has been available in new construction homes since 2022, but this marks the first time you can buy it separately.

While Apple's next line of smartwatches is expected to be a minor upgrade, the company is working on a revamped "Watch X" update for the device's 10th anniversary. Bloombeg's Mark Gurman reports: Apple is planning a splashy upgrade for its smartwatch, but you won't see it this year. The 2023 models, due next month, will be a minor refresh -- the kind of incremental update that has characterized the product in recent years. Inside Apple, executives have pondered the idea of switching away from this slow-but-steady annual upgrade cycle. The deliberations haven't gotten far (Apple has dutifully released a new watch every year since the category debuted in 2015), but recent updates to the device underscore why this is even a discussion. [...] Fact is, Apple isn't giving consumers many reasons to buy a new watch with each generation. The company did launch an impressive new Apple Watch Ultra last year that spurred upgrades at the high end, but 2023 will (once again) be another low-key year. [...]

Because of the Apple Watch's slow evolution over the years, the design has remained largely the same since the Series 4 launched in 2018 -- aside from the Ultra model. But that's poised to change. Apple is planning a "Watch X" model to mark the device's 10-year anniversary, and it promises to be the biggest overhaul yet. (The category was unveiled in 2014 and released the following year, so Apple is planning to launch Watch X either in 2024 or 2025.) With the X model, Apple designers are working on a thinner watch case and have explored changing the way bands are attached to the device.

Starting with the original Apple Watch, bands have slid into the sides of the chassis and attached with a locking mechanism. Keeping that design the same let the bands stay compatible with old and new models, but it has downsides. People involved in the development of new Apple Watches say the system takes up a considerable amount of space that could be better filled with a bigger battery or other components. To that end, the company has explored a new magnetic band attachment system, though it's unclear if it will be ready or used in the Watch X revamp. Even bigger changes are coming as well: a microLED display that tops the color and clarity of the current OLED screens, as well as a technology for monitoring blood pressure.

A retired Technical Fellow from Rockwell Collins "released a 65-page paper that details an easy-to-understand, relatively inexpensive, and feasible plan to turn an asteroid into a space habitat," reports Universe Today (in an article republished at Science Alert): Dr. David W. Jensen breaks the discussion into three main categories — asteroid selection, habitat style selection, and mission strategy to get there (i.e., what robots to use)... He eventually settled on a torus as the ideal habitat type and then dives into calculations about the overall station mass, how to support the inner wall with massive columns, and how to allocate floor space.

All important, but how exactly would we build such a massive behemoth? Self-replicating robots are Dr. Jensen's answer. The report's third section details a plan to utilize spider robots and a base station that can replicate themselves. He stresses the importance of only sending the most advanced technical components from Earth and using materials on the asteroid itself to build everything else, from rock grinders to solar panels...

With admittedly "back-of-the-envelope" calculations, Dr. Jensen estimates that the program would cost only $4.1 billion. That is far less than the $93 billion NASA plans to spend on the Apollo program. And the result would be a space habitat that provides 1 billion square meters of land that didn't exist before. That's a total cost of $4.10 per square meter to build land — in space. Possibly even more impressive is the timeline — Dr. Jensen estimates that the entire construction project could be done in as little as 12 years. However, it will still take longer to fill the habitat with air and water and start regulating its temperature.

"Teams across Google are working hard to prepare the web for the migration to quantum-resistant cryptography," writes Chrome's technical program manager for security, Devon O'Brien.

"Continuing with our strategy for handling this major transition, we are updating technical standards, testing and deploying new quantum-resistant algorithms, and working with the broader ecosystem to help ensure this effort is a success." As a step down this path, Chrome will begin supporting X25519Kyber768 for establishing symmetric secrets in TLS, starting in Chrome 116, and available behind a flag in Chrome 115. This hybrid mechanism combines the output of two cryptographic algorithms to create the session key used to encrypt the bulk of the TLS connection:

X25519 — an elliptic curve algorithm widely used for key agreement in TLS today
Kyber-768 — a quantum-resistant Key Encapsulation Method, and NIST's PQC winner for general encryption

In order to identify ecosystem incompatibilities with this change, we are rolling this out to Chrome and to Google servers, over both TCP and QUIC and monitoring for possible compatibility issues. Chrome may also use this updated key agreement when connecting to third-party server operators, such as Cloudflare, as they add support. If you are a developer or administrator experiencing an issue that you believe is caused by this change, please file a bug.
The Register delves into Chrome's reasons for implementing this now: "It's believed that quantum computers that can break modern classical cryptography won't arrive for 5, 10, possibly even 50 years from now, so why is it important to start protecting traffic today?" said O'Brien. "The answer is that certain uses of cryptography are vulnerable to a type of attack called Harvest Now, Decrypt Later, in which data is collected and stored today and later decrypted once cryptanalysis improves." O'Brien says that while symmetric encryption algorithms used to defend data traveling on networks are considered safe from quantum cryptanalysis, the way the keys get negotiated is not. By adding support for a hybrid KEM, Chrome should provide a stronger defense against future quantum attacks...

Rebecca Krauthamer, co-founder and chief product officer at QuSecure, told The Register in an email that while this technology sounds futuristic, it's useful and necessary today... [T]he arrival of capable quantum computers should not be thought of as a specific, looming date, but as something that will arrive without warning. "There was no press release when the team at Bletchley Park cracked the Enigma code, either," she said.
