Musk can't convince judge public doesn't care about where AI training data comes from:

Elon Musk's xAI has lost its bid for a preliminary injunction that would have temporarily blocked California from enforcing a law that requires AI firms to publicly share information about their training data.

xAI had tried to argue that California's Assembly Bill 2013 (AB 2013) forced AI firms to disclose carefully guarded trade secrets.

The law requires AI developers whose models are accessible in the state to clearly explain which dataset sources were used to train models, when the data was collected, if the collection is ongoing, and whether the datasets include any data protected by copyrights, trademarks, or patents. Disclosures would also clarify whether companies licensed or purchased training data and whether the training data included any personal information. It would also help consumers assess how much synthetic data was used to train the model, which could serve as a measure of quality.

However, this information is precisely what makes xAI valuable, with its intensive data sourcing supposedly setting it apart from its biggest rivals, xAI argued. Allowing enforcement could be "economically devastating" to xAI, Musk's company argued, effectively reducing "the value of xAI's trade secrets to zero," xAI's complaint said. Further, xAI insisted, these disclosures "cannot possibly be helpful to consumers" while supposedly posing a real risk of gutting the entire AI industry.

Specifically, xAI argued that its dataset sources, dataset sizes, and cleaning methods were all trade secrets.

"If competitors could see the sources of all of xAI's datasets or even the size of its datasets, competitors could evaluate both what data xAI has and how much they lack," xAI argued. In one hypothetical, xAI speculated that "if OpenAI (another leading AI company) were to discover that xAI was using an important dataset to train its models that OpenAI was not, OpenAI would almost certainly acquire that dataset to train its own model, and vice versa."

However, in an order issued on Wednesday, US District Judge Jesus Bernal said that xAI failed to show that California's law, which took effect in January, required the company to reveal any trade secrets.

Chinese Loongson 3C6000 CPUs now have heat spreaders with words in Cyrillic?

The specifications of Tramplin's 16-core Irtysh C616 (2.20 GHz, 32MB L3, quad-channel DDR4-3200 memory, 844.8 GFLOPS, 100W – 120W TDP) and 32-core Irtysh C632 processors (2.10 GHz, 64MB L3, octa-channel DDR4-3200 memory, 1612.8 GFLOPS, 180W – 200W TDP) are identical to those of Loongson's 16-core LS3C6000/S and 32-core LS3C6000/D CPUs down to a single number, which isn't something that happens usually unless we are dealing with the very same silicon.

Indeed, Tramplin Electronics was first registered on April 4, 2025, so the company is less than a year old. It is impossible to develop a processor from scratch (even based on a known/licensed ISA), find a production partner, build its physical design, tape it out, and get samples in this short of a time frame. In fact, a year is barely enough to bring up a new CPU based on an existing platform (this may easily take a couple of years for a company of AMD's or Intel's size), not to mention developing one from scratch. That said, even though the processors were made in the third week of 2026, it looks like these are regular Loongson LS3C6000 CPUs that carry Cyrillic inscriptions.

Now that Russia-based entities cannot legally obtain high-performance CPUs from companies like AMD or Intel, the only way for the country to retain access to more or less contemporary processors is to buy them illegally in nearby countries, or get Chinese processors from the People's Republic. Apparently, we are dealing with the second option here, albeit with an attempt to disguise Chinese processors as those developed in Russia. Interestingly, the source of the river Irtysh — after which the CPUs are named — is in China.

GFiber and Astound to merge with Alphabet selling majority stake to Stonepeak:

Google Fiber, now officially called GFiber, is being sold to private equity firm Stonepeak and will be combined with cable-and-fiber firm Astound Broadband to create a larger Internet service provider.

Google owner Alphabet announced Wednesday that it will keep only a minority stake in the fiber ISP that launched with grand ambitions in 2012 but scaled back its expansion plans in 2016. Alphabet and Astound owner Stonepeak announced "an agreement to combine GFiber with Astound Broadband, creating a leading independent fiber provider," with the merged company to be "majority owned by Stonepeak, an investment firm specializing in infrastructure and real assets."

The deal is subject to regulatory approvals and other closing conditions, with an expected closing date in Q4 of this year. The sale price was not disclosed. The deal will help GFiber take "a major step toward its goal of operational and financial independence" and obtain the "external capital and strategic focus needed to accelerate its next phase of growth," the announcement said.

[...] Astound is already the product of industry consolidation via a series of private equity deals that combined Wave Broadband, RCN, and Grande Communications. A research note from the New Street analyst firm said GFiber offers service at 2.8 million locations in 15 states, while Astound's service area has 4.45 million locations in 12 states and the District of Columbia. Most of Astound's network is cable broadband, but it has 892,014 fiber locations and 44,548 copper locations.

[...] The combined GFiber/Astound company will face competition in most of its territory from at least one cable or fiber/copper provider. That includes AT&T at 53 percent of locations, Comcast at 46 percent of locations, Charter at 43 percent of locations, Verizon at 22 percent of locations, and Lumen (CenturyLink) at 11 percent.

The reliable internet connections provided by Starlink offer a huge advantage on the battlefield. But as access is dependent on the whims of controversial billionaire Elon Musk, militaries are looking to build their own version:

Starlink’s satellite constellation provides a reliable internet connection to almost anywhere on Earth, conferring an advantage on the modern battlefield. But it is also run by controversial billionaire Elon Musk, presenting a risk to militaries that could easily find themselves cut off. So, now countries are racing to build their own version.

The Starlink network consists of almost 10,000 satellites that offer internet connections across most of the planet via small dishes on the ground. The company says it has more than 10 million paying civilian customers, but the service is also used militarily. Modern warfare is a data-intensive business, with intelligence, video feeds and drone control instructions being beamed back and forth 24 hours a day.

Unlike radios, which can be easily jammed by adversaries, Starlink’s signals point straight up from ground stations to space and are relatively robust. And because receivers are cheap, they can be issued to small military units and even used on remotely operated ground and aerial drones.

But in a world where global tensions are ratcheting up and states are seeking sovereignty in everything from computer chip manufacture to nuclear deterrence, relying on a foreign service like Starlink to coordinate troops is considered increasingly risky. Especially when it is controlled by a mercurial figure like Musk.

Both Ukraine and Russia have used Starlink since the 2022 invasion, with reports suggesting that Russia has guided attack drones with it. But in February, the company restricted access to registered users and effectively shut Russian troops out of the service. The move is reported to have had serious repercussions for Russia’s ability to coordinate its military and provided Ukraine an advantage, at least in the short term. No other nation wants to find itself in the same boat.

The Iran war is going to be costly for the tech sector:

While Meta announced the completion of the core of the project, it’s still working on the Pearls section of the network, which was intended to connect Persian Gulf states, including Iraq, Kuwait, Saudi Arabia, Bahrain, Qatar, United Arab Emirates, and Oman, as well as Pakistan and India, to the rest of Africa and several European countries. The publication says that the bulk of the undersea cable has already been laid but is yet to be connected to the onshore landing stations.

Aside from the trouble in the Middle East, undersea cables in Europe and East Asia are constantly under threat from being cut by ships that are part of “shadow fleets” — vessels with murky ownerships but often indirectly controlled by states like Russia and China conducting hybrid warfare. Because of this, Meta has been planning to build a 50,000-km (30,000-mile) long undersea cable that will bypass current geopolitical hotspots called Project Waterworth. But despite being announced for 2025, it’s expected that it will take several more years before it is completed and goes online.

https://arstechnica.com/ai/2026/03/nvidia-is-reportedly-planning-its-own-open-source-openclaw-competitor/

Chipmaker Nvidia is preparing to launch its own open source AI agent platform to compete with the likes of OpenClaw, according to a recent Wired report.

The magazine cites "people familiar with the company's plans" in reporting that Nvidia has been pitching the platform, which it is calling NemoClaw, to various corporate partners ahead of its annual developer conference next week. Salesforce, Cisco, Google, Adobe, and CrowdStrike are among the companies said to be in talks for those partnerships, though it's unclear what specific benefits those companies would receive for their association with the open source tool.

NemoClaw, as the somewhat awkward name suggests, would be a direct competitor of OpenClaw (previously known as Moltbot and Clawdbot), the system that attracted widespread attention in January for letting users direct "always-on" AI agents from their personal machines, using any number of underlying models. Last month, OpenAI hired OpenClaw creator Peter Steinberger "to drive the next generation of personal agents," as founder Sam Altman put it, though the OpenClaw project will be run by an independent foundation with OpenAI's support.

And that is not nearly enough:

Teenagers across the country are getting less sleep, a researcher from the University of Connecticut reports on March 2 in JAMA. And the problem appears to be societal.

Teens not getting enough sleep has been reported as a problem in the medical literature since at least the turn of the 20th century: a 1905 study in The Lancet of the sleep hours of boys in British boarding schools worried that they were not getting enough sleep due to nighttime lighting, and suggested that "late to bed and early to rise is neither physiological nor wise."

Later, in the 1950s, public concern focused on evening entertainment such as radio and television keeping teens awake too late. More recently, research has connected too little sleep with overstimulation, mental health problems, accidents, and academic challenges.

But teens are getting even less sleep than they used to, report UConn School of Medicine psychiatric epidemiologist T. Greg Rhee and colleagues in their latest look at the Youth Risk Behavior Survey done by the Centers for Disease Control and Prevention (CDC). The Youth Risk Behavior Survey provides nationally-representative data to examine long-term trends of risk behaviors in teens.

Rhee and his colleagues' analysis of the survey data from 2007 to 2023 shows more than 50% of teens are reporting less than 5 hours of sleep a night in the most recent survey, more sleep deprived teens than in any previous survey. Less than five hours of sleep a night is considered very short sleep, and is associated with emotional regulation issues such as anxiety and depression, poor academic performance or neurocognitive development, and increased risks for obesity and diabetes.

Teens getting less than 5 hours of sleep a night increased across all subgroups in the most recent survey, whether they had risk factors such as depressive thoughts, using controlled substances, or had large amounts of screen time, or no risk factors at all.

The number of teens getting sufficient sleep, defined as eight or more hours a night, dropped from more than 30% in 2007 to less than 25% in 2023.

"These trends highlight the need for population-level interventions among teens. For example, later school start times can help with longer sleep, which may lead to better mental health outcomes and greater academic engagement," said Rhee and his colleagues. More research is needed into which interventions might be effective on the population level. For example, Rhee suggests researchers examine whether reforming academic or extracurricular schedules to reduce evening demands could improve sleep health among teens.

Amazon Expands Health AI Access For Virtual Health Care

https://www.cnet.com/tech/amazon-expands-health-ai-access-for-amazon-users-looking-to-receive-virtual-healthcare/

Health AI will be available to more US Amazon users this year.

Other functions Health AI can help out with include filling prescription refills through Amazon Pharmacy and connecting you with One Medical doctors via video, in-person appointments or messages. 

Health AI isn't the first chatbot to offer health guidance. In January, OpenAI introduced ChatGPT Health, which similarly answers health questions, deciphers lab results and connects to your Apple Health app and medical records with your permission. Anthropic likewise introduced Claude for Healthcare, which connects to Apple Health and can help you understand and sort through health care tasks such as medical bills. Apple is also rumored to be working on its own AI health coach or assistant. 

There have been concerns about chatbots and their use for sensitive topics such as health advice, because misguidance can cause harm. We would always caution against inputting private, sensitive information into AI bots and to take their advice with a grain of salt, since AI is known to hallucinate. Double-check with your provider about any health care advice an AI chatbot gives you.

Amazon's virtual assistant is said to be HIPAA-compliant and intended only for medical support, not to replace a health care provider. Health AI will be able to answer questions such as: "Can you explain my recent cholesterol results and what they mean for me?" or "What allergy medications are safe with my current prescriptions?"

An Amazon representative didn't immediately respond to a request for further comment.

AI Chatbots Miss More Than Half Of Medical Diagnoses, Study Finds

https://www.cnet.com/health/medical/chatbots-miss-medical-diagnoses/

ChatGPT was one of the chatbots used in Nature Medicine's study.

The study acknowledged that LLMs now achieve scores on medical knowledge benchmarks comparable to passing the US Medical Licensing Exam, and that clinical documents from LLMs "are rated as equivalent to or better than those written by doctors."

However, a problem was revealed when the study's participants tried to get the same results by asking the LLM questions but were not successful. This is because users often didn't provide enough information, the study found. It reports that in 16 of 30 sampled interactions, initial messages contained only partial information.

"In two cases, LLMs provided initially correct responses but added new and incorrect responses after the users added additional details," the study said, suggesting that conversing more with the chatbots did not improve the probability of receiving a correct medical diagnosis. 

After the initial diagnosis, the LLMs provided the correct follow-up steps to the person just 44.2% of the time. 

Meta's Llama 3 was one of the large language models used in the study.

According to a survey by OpenAI, which owns ChatGPT, 3 in 5 US adults report using AI for health. "They are using AI to get information when they first feel unwell, consulting it to prepare for their visits with their clinicians, and using it to better comprehend patient instructions and recommendations," OpenAI stated.  

And although there's a small disclaimer on ChatGPT's website that reads, "ChatGPT can make mistakes. Check important info," many people do take the chatbot's word for fact.  

The study serves as a reminder that ChatGPT and similar chatbots should not be relied upon for medical guidance, particularly in serious situations.

New study challenges notion that aging means decline, finds many older adults improve over time:

Aging in later life is often portrayed as a steady slide toward physical and cognitive decline. But a new study by scientists at Yale University suggests an alternate narrative — that older individuals can and do improve over time, and their mindset toward aging plays a major part in their success.

Analyzing more than a decade of data from a large, nationally representative study of older Americans, lead author Dr. Becca R. Levy, PhD, a professor of social and behavioral sciences at the Yale School of Public Health (YSPH), found that nearly half of adults aged 65 and older showed measurable improvement in cognitive function, physical function, or both, over time.

The improvements were not limited to a small group of exceptional individuals and, notably, were linked to a powerful but often overlooked factor: how people think about aging itself.

"Many people equate aging with an inevitable and continuous loss of physical and cognitive abilities," said Dr. Levy, an international expert on psychosocial determinants of aging health. "What we found is that improvement in later life is not rare, it's common, and it should be included in our understanding of the aging process."

For the study, the researchers followed more than 11,000 participants in the Health and Retirement Study, a federally supported longitudinal survey of older Americans. The research team tracked changes in cognition using a global performance assessment, and physical function using walking speed — often described by geriatricians as a "vital sign" because of its strong links to disability, hospitalization, and mortality.

Over a follow-up period of up to 12 years, 45% of participants improved in at least one of the two domains, according to the study. About 32% improved cognitively, 28% improved physically, and many experienced gains that exceeded thresholds considered clinically meaningful. When participants whose cognitive scores remained stable over that period (rather than declining) were included, more than half defied the stereotype of inevitable deterioration in cognition.

"What's striking is that these gains disappear when you only look at averages," said Dr. Levy, author of the book "Breaking the Age Code: How Your Beliefs About Aging Determine How Long & How Well You Live."

"If you average everyone together, you see decline," Dr. Levy continued. "But when you look at individual trajectories, you uncover a very different story. A meaningful percentage of the older participants that we studied got better."

Every month most people receive a bill for water, gas, electricity, internet, or insurance, and in the future, if the CEO of OpenAI has anything to say about it, a monthly bill for AI use.

OpenAI CEO Sam Altman has sparked debate after suggesting artificial intelligence could soon be sold like electricity or water – with users paying for "intelligence" on a meter.

The ChatGPT creator made the bold prediction during an appearance at the BlackRock US Infrastructure summit in Washington this week

"We see a future where intelligence is a utility, like electricity or water, and people will buy it from us on a meter"

"Fundamentally, our business and I think the business of every other model provider is going to look like selling tokens.

"They may come from bigger or smaller models, it makes them more or less expensive. They may use more or less reasoning, which also makes them more or less expensive.

"They may be running all the time in the background trying to help you out. They may run only when you need them if you want to pay less. They may work super hard and spend hundreds of millions of dollars on a single problem and that's really valuable."

The idea provoked backlash from commentators with one person posting on Twitter to say "I don't need AI to live, dude. I've literally never seen a more delusional tech founder in my life".

Where do you stand on this? Would you sign up for a monthly billing for AI use, or can you live without it?

A new, general theory argues it is not about costly or exaggerated show-offs but about the inherent trade-offs between investments and benefits animals (and humans) face when they signal:

For decades, scientists have tried to answer a simple question: why be honest when deception is possible? Whether it is a peacock's tail, a stag's roar, or a human's résumé, signals are means to influence others by transmitting information and advantages can be gained by cheating, for example by exaggeration. But if lying pays, why does communication not collapse?

The dominant theory for honest signals has long been the handicap principle, which claims that signals are honest because they are costly to produce. It argues that a peacock's tail, for example, is an honest signal of a male's condition or quality to potential mates because it is so costly to produce. Only a high-quality birds could afford such a handicap, wasting resources growing it, demonstrating their superb quality to females, whereas poor quality males cannot afford such ornaments.

A new synthesis by Szabolcs Számadó, Dustin J. Penn and István Zachar (from the Budapest University of Technology and Economics, University of Veterinary Medicine Vienna and HUN-REN Centre for Ecological Research, respectively) challenges that logic. They argue that honesty does not depend on how costly or wasteful a signal is, but rather on the trade-offs between investments and benefits, faced by signalers.

They explain that signals are not honest because they are costly, instead, honesty evolves when it is beneficial and deception is costly. Previous studies inspired by the handicap principle (refuted by the authors in the paper) misleadingly focused on only the costs of signalling. Yet biological functions, like signalling, cannot be understood in the evolutionary context without their benefits, often realized in the long run.

The new theory, called Signalling Trade-Off Theory, shifts the focus from absolute cost to choice in what to invest. In biology, every organism faces competing demands: investing more in one thing means having less for another. Time spent courting cannot be spent feeding; energy put into bright feathers cannot be used for immune defence. These are trade-offs. And these are also present in economic choices for humans. Crucially, they differ between individuals. A healthy, well-fed animal can afford different choices than a weak or starving one. According to several theoretical studies, signalling trade-offs and not absolute costs define whether deception or honesty evolves.

"Signals, in theory, can be absolutely cost free in terms of immediate energy investment." – István Zachar, one of the authors explains – "Honesty does not come from how much a signal harms you but from what kind of cost-benefit ratio you can realize with it." And this trade-off between investments and benefits is defined by the condition of the individual.

According to theory, honest signals arise when these trade-offs respect the true quality of the individual, i.e. are condition-dependent. High-quality individuals get more return from the same investment than low-quality ones. As a result, the best strategy for a strong individual is to signal more, while the best strategy for a weak individual is to signal less. "Both are behaving optimally," the author says, "but because their trade-offs are different, their signals end up revealing who they are." This is how honesty is defined.

[...] Why does this matter beyond biology? Because the same logic applies to human communication, from advertising to cooperation based on reputation. We all operate under trade-offs (inherited or learnt) between short-term gains and long-term consequences. Signals are reliable when those trade-offs differ across people in ways that make bluffing unprofitable.

"The real question is not 'how costly is this signal?'" – Zachar says – "It is 'what would it cost this person, in terms of what else they could have done, to fake it?'"

By reframing honesty in terms of trade-offs rather than waste, the new theory brings signalling back in line with a broader understanding of evolution: organisms are not rewarded for squandering resources, but for allocating them efficiently under constraints. In that light, honest communication is not a miracle. It is a natural outcome of living in a non-quantum biological world where every choice closes off another.

After 14 years in orbit, NASA's Van Allen Probe A dropped back into the atmosphere over the Pacific Ocean:

The Van Allen Probe A satellite spent seven years measuring radiation and nearly 14 years total in space. 

Once the mission ended, NASA originally calculated that the probes would fall back to Earth sometime in 2032. The agency acknowledges, though, that it didn't account for the current solar maximum, a period of increased instability on the sun, which leads to more intense space weather events. NASA says the extra solar wind caused drag on the probe, causing a descent faster than initial calculations predicted. 

Data from these probes is still used today to measure and predict the impact of solar winds and radiation on communications systems, navigation satellites, power grids and even astronauts in space. The radiation that the Van Allen Probes studied is also the same radiation responsible for all of those gorgeous auroras Earth has been getting lately.

NASA said most of the spacecraft likely burned up as it sped downward through the atmosphere, although some components may have survived.

The agency originally predicted the return for around 7:45 p.m. ET Tuesday, noting that it could take up to 24 hours for the event to occur. It was off by 11 hours.   

Before the splashdown, NASA predicted a 1 in 4,200 chance of any wreckage landing somewhere that could cause human harm. The coordinates that the space agency gave Wednesday for the reentry point -- approximately 2 degrees south latitude and 255.3 degrees east longitude -- are just south of the Equator and west of South America, meaning well out over the ocean. 

The probe's partner, Van Allen Probe B, is also scheduled to crash back to Earth, but it isn't expected to arrive until 2030 or later.

https://www.slashgear.com/2119616/americans-diy-solar-panels-avoid-high-electric-bill/

Homeowners and renters alike have seen utility costs increase in the mid-2020s, directly impacting their monthly budgets. This is due to a range of factors, from some providers having virtual monopolies in specific areas to attempts to offset the costs of power-hungry AI data centers. Even common mistakes can run up utility costs. To that end, some have turned to homemade solar setups to generate their own energy and save money — all without letting their utility providers know, avoiding potentially costly connection fees on their already rising bills.

These small, relatively simple setups are known as balcony or plug-in solar: two to four panels that can be placed in an outdoor area, like a balcony, and powered via a wall outlet to harvest solar energy. These setups are easy to hook up, much simpler than a full-on solar roof installation, and save money on utility bills — alongside the usual environmental benefits of solar panels.

Reports by outlets such as Canary Media, The Washington Post, and CNN indicate that savings can range from around $100 per year to $35 to $50 per month. Exact numbers depend on elements like location, existing utility rates, and the size and strength of the solar setup. While DIY solar does seem like a good idea, there's also the legal side of it to be aware of. Unfortunately, laws across the United States are a bit hazy on the matter, but that could change soon.

[...] At the time of publication, the only state with solid DIY solar laws on the books is Utah. In 2025, the state passed House Bill 340, or the Solar Power Amendments bill, which approves and encourages the use of small solar setups in residential settings. These devices and their owners are exempt from needing approval and from utility provider fees. While many states haven't even introduced potential legislation on this front, others, such as New York and California, have taken steps to make balcony solar legal and offer protections to those hoping to equip their homes with it.

Depending on size, plug-in solar setups can cost between a few hundred and over $1,000, offering between 200 and 800 watts of power. This means that users should have no problem running lights, device chargers, radios, and fans, amongst others, from their balcony solar setups. Some may even be able to run appliances like refrigerators.

[...] While customer complaints indicate that some solar companies are worth avoiding, there are many more vying for the business of homeowners and renters. Given advancing legislation supporting balcony solar and increasing energy costs spurring its adoption, it stands to reason that some of these companies' offerings will soon become more popular with Americans.

Troubled SaaS icon Adobe tumbled after hours, sending its stock to 7 year lows after the company announced that CEO Shantanu Narayen will resign from the creative software giant amid deep skepticism about the company's ability to survive and thrive in the AI era:

The CEO change "adds questions around strategic continuity, capital allocation priorities, and pace of innovation," Grace Harmon, an analyst at Emarketer, said in an email. "Investors will likely focus on whether incoming leadership maintains a balance between disciplined execution and aggressive AI investment, especially as competition in creative and enterprise AI intensifies."

The company also gave a sales forecast for the current quarter that just topped estimates, but failed to ease investor fears that the software maker is being left behind by new competitors.

In the fiscal first quarter, revenue increased 12% to $6.4 billion, compared with analysts' average estimate of $6.28 billion. Adjusted earnings were $6.06 a share in the period, which ended Feb. 27. The average projection was $5.88 a share.

Annual recurring revenue for the company's AI-first products such as Firefly more than tripled compared to the same period last year, Narayen said in a script prepared for a conference call scheduled after the results. In September, Adobe said sales from these products exceeded $250 million.

[...] The shares fell about 6% in extended trading after closing at $269.78 in New York. The stock has declined about 23% this year, and is about to drop the lowest level since 2019.

Most of the devices are made by Asus and are located in the US:

Researchers say they have uncovered a takedown-resistant botnet of 14,000 routers and other network devices—primarily made by Asus—that have been conscripted into a proxy network that anonymously carries traffic used for cybercrime.

The malware—dubbed KadNap—takes hold by exploiting vulnerabilities that have gone unpatched by their owners, Chris Formosa, a researcher at security firm Lumen's Black Lotus Labs, told Ars. The high concentration of Asus routers is likely due to botnet operators acquiring a reliable exploit for vulnerabilities affecting those models. He said it's unlikely that the attackers are using any zero-days in the operation.

The number of infected routers averages about 14,000 per day, up from 10,000 last August, when Black Lotus discovered the botnet. Compromised devices are overwhelmingly located in the US, with smaller populations in Taiwan, Hong Kong, and Russia. One of the most salient features of KadNap is a sophisticated peer-to-peer design based on Kademlia, a network structure that uses distributed hash tables to conceal the IP addresses of command-and-control servers. The design makes the botnet resistant to detection and takedowns through traditional methods.

"The KadNap botnet stands out among others that support anonymous proxies in its use of a peer-to-peer network for decentralized control," Formosa and fellow Black Lotus researcher Steve Rudd wrote Wednesday. "Their intention is clear: avoid detection and make it difficult for defenders to protect against."

[...] Kademlia uses a 160-bit space to designate (1) keys—which are unique bitstrings derived by hashing a chunk of data—and (2) node IDs, both of which are assigned to each node. Nodes then store the keys of other nodes. The stored keys are organized by their similarity to the ID of the node storing them. Proximity is measured by XOR distance, a mathematical means of mapping a network. When a node polls another node, it uses this metric to locate other nodes with the closest distance to the key it's looking for until it finally finds a match. KadNap, a variant of Kademlia, obtains the key to be searched through a BitTorrent node.
