White Hat Hackers Earn $500,000 On First Day of Pwn2Own Ireland 2024 (securityweek.com)

(Thursday October 24, 2024 @11:21AM (BeauHD) from the not-too-shabby dept.)

An anonymous reader quotes a report from SecurityWeek.com:

> White hat hackers taking part in the Pwn2Own Ireland 2024 contest organized by Trend Micro's Zero Day Initiative (ZDI) have [1]earned half a million dollars on the first day of the event , for exploits targeting NAS devices, cameras, printers and smart speakers. The highest single reward, $100,000, was earned by Sina Kheirkhah of Summoning Team, who chained a total of nine vulnerabilities for an attack that went from a QNAP QHora-322 router to a TrueNAS Mini X storage device. Another exploit chain involving the QNAP QHora-322 and TrueNAS Mini X products was demonstrated by Viettel Cyber Security, but this team earned only $50,000.

>

> A significant reward was also earned by Jack Dates of RET2 Systems, who received $60,000 for hacking a Sonos Era 300 smart speaker. QNAP TS-464 and Synology DiskStation DS1823XS+ NAS device exploits earned $40,000 each for two different teams. Participants also successfully demonstrated exploits against the Lorex 2K WiFi, Ubiquity AI Bullet, and Synology TC500 cameras, and HP Color LaserJet Pro MFP 3301fdw and Canon imageCLASS MF656Cdw printers. These attempts earned the hackers between $11,000 and $30,000. According to ZDI, a total of $516,250 was paid out on the first day of Pwn2Own Ireland for over 50 unique vulnerabilities.

Linus Torvalds Comments On The Russian Linux Maintainers Being Delisted (phoronix.com)

(Thursday October 24, 2024 @11:21AM (BeauHD) from the compliance-requirements dept.)

Ancient Slashdot reader [1]szo shares a report from Phoronix:

> Quietly merged into this week's Linux 6.12-rc4 kernel was a patch that [2]removes a number of kernel maintainers from being noted in the official MAINTAINERS file that recognizes all of the driver and subsystem maintainers. [...] [Greg Kroah-Hartman who authored the patch] simply [3]commented in there: "Remove some entries due to various compliance requirements. They can come back in the future if sufficient documentation is provided." [...] The commonality of all these maintainers being dropped? They appear to all be Russian or associated with Russia. Most of them with .ru email addresses.

Linux creator Linus Torvalds has since [4]commented on the situation :

> Ok, lots of Russian trolls out and about. It's entirely clear why the change was done, it's not getting reverted, and using multiple random anonymous accounts to try to "grass root" it by Russian troll factories isn't going to change anything. And FYI for the actual innocent bystanders who aren't troll farm accounts - the "various compliance requirements" are not just a US thing.

>

> If you haven't heard of Russian sanctions yet, you should try to read the news some day. And by "news," I don't mean Russian state-sponsored spam. As to sending me a revert patch - please use whatever mush you call brains. I'm Finnish. Did you think I'd be *supporting* Russian aggression? Apparently it's not just lack of real news, it's lack of history knowledge too.

Adobe Made Its Painting App Completely Free To Take On Procreate

(Thursday October 24, 2024 @11:21AM (BeauHD) from the no-more-paywall dept.)

Adobe's [1]Fresco painting app is [2]now free for everyone , in an attempt to lure illustrators to join its creative software suite. The Verge reports:

> Fresco is essentially Adobe's answer to apps like Procreate and Clip Studio Paint, which all provide a variety of tools for both digital art and simulating real-world materials like sketching pencils and watercolor paints. Adobe Fresco is designed for touch and stylus-supported devices, and is available on iPad, iPhone, and Windows PCs. The app already had a free-to-use tier, but premium features like access to the full Adobe Fonts library, a much wider brush selection, and the ability to import custom brushes previously required a $9.99 annual subscription. That's pretty affordable for an Adobe subscription, but still couldn't compete with Procreate's $12.99 one-time purchase model.

>

> Starting today, all of Fresco's premium features are no longer locked behind a paywall. The app first launched in 2019 and isn't particularly well-known compared to more established Adobe apps like Photoshop and Illustrator that feature more complex, professional design tools. Fresco still has some interesting features of its own, like reflective and rotation symmetry (which mirror artwork as you draw) and the ability to quickly animate drawings with motion presets like "bounce" and "breathe."

Apple and Goldman Sachs Fined Millions For Misleading Apple Card Holders

(Thursday October 24, 2024 @11:21AM (msmash) from the reputational-damage dept.)

Goldman Sachs and Apple will [1]pay $89 million in penalties and customer refunds over widespread service failures and deceptive practices in their joint Apple Card venture, U.S. consumer watchdog CFPB said on Wednesday.

The agency found Goldman mishandled credit card disputes while Apple failed to forward thousands of customer complaints. Both companies deceived users about interest-free payment plans for Apple devices, affecting hundreds of thousands of cardholders since the card's 2019 launch. Goldman must pay $64.8 million in fines and refunds, while Apple faces a $25 million penalty. The bank is now barred from issuing new credit cards without regulatory approval.

Internet Users Ask FCC To Ban Data Caps (arstechnica.com)

(Thursday October 24, 2024 @11:21AM (BeauHD) from the free-refills dept.)

An anonymous reader quotes a report from Ars Technica:

> It's been just a week since US telecom regulators [1]announced a formal inquiry into broadband data caps, and the [2]docket is filling up with comments from users who say they shouldn't have to pay overage charges for using their Internet service. The docket has about 190 comments so far, nearly all from individual broadband customers.

>

> Federal Communications Commission dockets are usually populated with filings from telecom companies, advocacy groups, and other organizations, but some attract comments from individual users of telecom services. The data cap docket probably won't break any records given that the FCC has fielded many millions of comments on net neutrality, but it currently tops the agency's [3]list of most active proceedings based on the number of filings in the past 30 days.

"Data caps, especially by providers in markets with no competition, are nothing more than an arbitrary money grab by greedy corporations. They limit and stifle innovation, cause undue stress, and are unnecessary," [4]wrote Lucas Landreth.

"Data caps are as outmoded as long distance telephone fees," [5]wrote Joseph Wilkicki. "At every turn, telecommunications companies seek to extract more revenue from customers for a service that has rapidly become essential to modern life." Pointing to taxpayer subsidies provided to ISPs, Wilkicki wrote that large telecoms "have sought every opportunity to take those funds and not provide the expected broadband rollout that we paid for."

In response to Trump-appointed FCC Commissioner Nathan Simington's [6]coffee refill analogy , internet users "Jonathan Mnemonic" and James Carter [7]wrote , "Coffee is not, in fact, internet service." They added: "Cafes are not able to abuse monopolistic practices based on infrastructural strangleholds. To briefly set aside the niceties: the analogy is absurd, and it is borderline offensive to the discerning layperson."

White-Collar Jobs Freeze Triggers MBA Applications Boom (msn.com)

(Wednesday October 23, 2024 @11:30PM (msmash) from the direction-of-wind dept.)

Applications to MBA programs jumped 12% in 2024, with full-time programs surging 32% to decade-high levels, WSJ [1]is reporting , citing the Graduate Management Admission Council's latest survey. Top-tier U.S. schools reported significant gains, with Columbia Business School seeing a 27% rise and Harvard Business School applications climbing 21%. So what's behind the surge? The story adds:

> Today, the U.S. job market is strong, and unemployment remains low. But lower wage positions in retail and dining, as well as healthcare and government, have fueled much of the labor market's growth over the past two years.

>

> A white-collar job market downturn that began with tech workers in 2022 has spread to other sectors. Major employers including Goldman Sachs, Lyft, Microsoft and PricewaterhouseCoopers have laid off a combined tens of thousands of workers this year. Hiring for roles that usually require a bachelor's degree dropped below 2019 levels in recent months, according to payroll provider ADP. That slump has been steeper for 20-somethings, who are running into a bottleneck on the lower rungs of the corporate ladder as more established professionals stay put.

Teen Dies After Intense Bond with Character.AI Chatbot

(Wednesday October 23, 2024 @05:22PM (msmash) from the breaking-news dept.)

A Florida teenager who formed a deep emotional bond with an AI chatbot [1]took his own life after months of intense daily interactions on Character.AI, a leading AI companion platform. Sewell Setzer III, 14, exchanged his final messages with "Dany," an AI character based on a Game of Thrones figure, before dying by suicide on February 28. His mother, The New York Times reports, plans to file a lawsuit against Character.AI, alleging the platform's "dangerous and untested" technology led to his death.

Character.AI, valued at $1 billion and claiming 20 million users, [2]in response said it would implement new safety features for minors, including time limits and expanded trigger warnings for self-harm discussions. The company's head of trust and safety Jerry Ruoti said they "take user safety very seriously."

New Commission May Ban English Water Companies From Making a Profit

(Thursday October 24, 2024 @03:00AM (msmash) from the how-about-that dept.)

Water companies in England could be [1]banned from making a profit under plans for a complete overhaul of the system. The Guardian:

> The idea is one of the options being considered by a new commission set up by the Department for Environment, Food and Rural Affairs (Defra) amid public fury over the way firms have prioritised profit over the environment. Sources at the department said they would consider forcing the sale of water companies in England to firms that would run them as not-for-profits. Unlike under nationalisation, the company would not be run by the government but by a private company, run for public benefit. The nonprofit model, which is widely used in other European countries, allows staff to be paid substantial salaries and bonuses but any profits on top of that are returned to the company.

Disney and Apple Are Splitting Over App Store Fees (msn.com)

(Thursday October 24, 2024 @03:00AM (msmash) from the tough-luck dept.)

If you want to sign up for a subscription to Hulu or Disney+, don't bother taking out your iPhone. Disney is now telling would-be customers to [1]pay for subscriptions on Disney's own site , instead of on Apple's App Store -- though people who've already started paying for either service via Apple can keep doing that. From a report:

> The two companies are still working together on some projects. But the App Store split does represent a rift between two longtime partners, so it's definitely worth noting.

>

> Disney's rationale is clear here: When customers sign up for Disney subscription services via Apple, Apple takes up to 15% of the monthly fees those services generate. And Disney CEO Bob Iger has made it clear that he doesn't want to pay that anymore. "We have to look at the way we're distributing," Iger said at an investor conference in May. "Unlike Netflix, we distribute largely through third-party app stores. There's obviously an advantage to that to some extent, but there's a cost to that, too. And we're looking at that."

Users Say T-Mobile Must Pay For Killing 'Lifetime' Price Lock (arstechnica.com)

(Thursday October 24, 2024 @03:00AM (msmash) from the I-am-alive dept.)

An anonymous reader shares a report:

> T-Mobile promised users who bought certain mobile plans that it would never raise their prices for as long as they lived -- but then raised their prices this year. So it's no surprise that 2,000 T-Mobile customers [1]complained to the government about a price hike on plans that were advertised as having a lifetime price lock. "I am still alive and T-Mobile is increasing the price for service by $5 per line. How is this a lifetime price lock?" one customer in Connecticut asked the Federal Communications Commission in a complaint that we obtained through a public records request.

>

> "I am not dead yet," a customer in New York wrote bluntly, saying they had bought a plan with a "guarantee for life." Both of those customers said they purchased T-Mobile's senior plan marketed to people aged 55 and up. While the price hikes apply to customers on various plans regardless of their age, many of the complaints to the FCC came from people in the 55+ age group. Some pointed out that if T-Mobile simply waits long enough, the carrier won't have to serve 55-and-up customers forever.

Pollution-Free Environment a 'Fundamental Right', India's Top Court Says (msn.com)

(Thursday October 24, 2024 @03:00AM (msmash) from the tussle-continues dept.)

Living in a pollution-free environment is [1]a fundamental right , India's Supreme Court said on Wednesday as it urged authorities to address deteriorating air quality in the north of the country. From a report:

> India's capital Delhi recorded a "very poor" air quality index of 364 on Wednesday, according to the Central Pollution Control Board, which considers readings below 50 to be good. Swiss group IQAir rated Delhi the world's most polluted city in its live rankings. The city battles toxic air every winter and authorities say much of the smoke comes from farmers illegally burning paddy stubble to clear their fields in the neighbouring breadbasket states of Punjab and Haryana. The Supreme Court pulled up the governments of both states for taking "selective action" against stubble burning, saying penal provisions were not being properly implemented.

Arm To Cancel Qualcomm's Chip Design License As Tech Feud Deepens (yahoo.com)

(Wednesday October 23, 2024 @05:22PM (msmash) from the bad-blood dept.)

Arm has moved to [1]cancel Qualcomm's architectural license agreement , escalating a legal battle that threatens to upend the global smartphone and PC chip markets. The British chip designer issued Qualcomm a 60-day termination notice for the license that allows the U.S. chipmaker to design custom processors using Arm's intellectual property. The cancellation could force Qualcomm to halt sales of products that generate much of its $39 billion annual revenue, Bloomberg reports.

The dispute stems from Qualcomm's $1.4 billion acquisition of chip startup Nuvia in 2021. Arm claims Qualcomm breached contract terms by using Nuvia's designs without permission, while Qualcomm maintains its existing agreement covers the acquired technology. The companies are set for a December trial to resolve Arm's 2022 breach-of-contract lawsuit and Qualcomm's countersuit. Arm is demanding Qualcomm destroy Nuvia designs created before the acquisition.

Why is Apple So Bad at Marketing Its TV Shows? (fastcompany.com)

(Wednesday October 23, 2024 @05:22PM (msmash) from the stranger-things dept.)

Speaking of [1]streaming services , an anonymous reader shares a story that [2]looks into Apple's entertainment offering :

> Ever [3]since its launch in 2019, Apple TV+ has been carving out an identity as the new home for prestige shows from some of Hollywood's biggest names -- the kind of shows that sound natural coming out of Jimmy Kimmel's mouth in monologue jokes at the Emmys. While the company never provides spending details, Apple is estimated to have spent at least $20 billion recruiting the likes of Reese Witherspoon, M. Night Shayamalan, and Harrison Ford to help cultivate its award-worthy sheen. For all the effort Apple has expended, and for all the cultural excitement around Ted Lasso during its three-season run, the streaming service has won nearly 500 Emmys ... while attracting just 0.2% of total TV viewing in the U.S.

>

> No wonder the company reportedly began reining in its spending spree recently. (Apple did not reply to a request for comment.) "It seems like Apple TV wants to be seen as a platform that's numbers-agnostic," says Ashley Ray, comedian, TV writer, and host of the erstwhile podcast TV I Say. "They wanna be known for being about the creativity and the love of making TV shows, even if nobody's watching them."

>

> The experience of enjoying a new Apple TV+ series can often be a lonely one. Adventurous subscribers might see an in-network ad about something like last summer's Sunny, the timely, genre-bending Rashida Jones series about murderous AI, and give it a shot -- only to find that nobody else is talking about it in their social media feeds or around the company Keurig machine. Sure, the same could be said for hundreds of other streaming series in the post-monoculture era, but most streaming companies aren't consistently landing as much marquee talent for such a limited library. (Apple currently has 259 TV shows and films compared to Netflix's nearly 16,000.)

>

> How is it possible for a streaming service to have as much high-pedigree programming as Apple TV+ does and so relatively few viewers, despite an estimated 25 million paid subscribers? How can shows starring Natalie Portman, Idris Elba, and Colin Farrell launch and even get renewed without ever quite grazing the zeitgeist? How does a show set in the same Monsterverse as Godzilla vs. Kong, and starring Kurt Russell and his roguishly charming son, not become a monster-size hit?

>

> For many perplexed observers, the blame falls squarely on Apple's marketing efforts, or seeming lack thereof.

Streaming Subscription Fees Have Been Rising While Content Quality is Dropping (arstechnica.com)

(Wednesday October 23, 2024 @05:22PM (msmash) from the double-whammy dept.)

An anonymous reader shares a report:

> Subscription fees for video streaming services have been on a steady incline. But despite subscribers paying more, surveys suggest they're becoming [1]less satisfied with what's available to watch .

>

> At the start of 2024, the industry began declaring the end of Peak TV, a term coined by FX Networks Chairman John Landgraf that refers to an era of rampant content spending that gave us shows like The Wire, Breaking Bad, and Game of Thrones. For streaming services, the Peak TV era meant trying to lure subscribers with original content that was often buoyed by critical acclaim and/or top-tier actors, writers, and/or directors. However, as streaming services struggle to reach or maintain profitability, 2024 saw a drop in the number of new scripted shows for the first time in at least 10 years, FX Research found.

>

> Meanwhile, overall satisfaction with the quality of content available on streaming services seems to have declined for the past couple of years. Most surveys suggest a generally small decline in perceived quality, but that's still perturbing considering how frequently streaming services increase subscription fees. There was a time when a streaming subscription represented an exclusive ticket to viewing some of the best new TV shows and movies. But we've reached a point where the most streamed TV show last year was Suits -- an original from the USA Network cable channel that ended in 2019.

Hong Kong officials discovered the [1]city's first dinosaur fossils on an uninhabited island in a local geopark, they said Wednesday. Initial examinations indicate the remains belong to a large Cretaceous-era dinosaur from 66-145 million years ago, with species identification pending further study. Associated Press adds:

> Experts speculate that the dinosaur was likely buried by sand and gravel after its death before it was later washed to the surface by a large flood, and subsequently buried again at the discovery site, it said.

Foursquare, one of the App Store's earliest success stories, will shut down its flagship city guide app on December 15 to focus on its check-in service Swarm, the company [1]said . The move reverses Foursquare's controversial 2014 decision to [2]split its platform into two apps : Swarm for check-ins and Foursquare for local recommendations and reviews. The strategy shift comes months after Foursquare laid off over 100 employees. Engadget [3]adds :

> Foursquare founder Dennis Crowley, who is currently co-chair of the company's board of directors, said in a post on Threads that the company is "doing fine," though he expressed disappointment with the news. "I would be lying if I didn't admit that I have been in a real funk these last few days over this news," he wrote.

Physicist Reveals Why You Should Run in The Rain (sciencealert.com)

(Wednesday October 23, 2024 @05:22PM (BeauHD) from the common-dilemmas dept.)

Theoretical Physicist Jacques Treiner, from the University of Paris Cite, explains [1]why you should run in the rain :

> ... Let p represent the number of drops per unit volume, and let a denote their vertical velocity. We'll denote Sh as the horizontal surface area of the individual (e.g., the head and shoulders) and Sv as the vertical surface area (e.g., the body). When you're standing still, the rain only falls on the horizontal surface, Sh. This is the amount of water you'll receive on these areas. Even if the rain falls vertically, from the perspective of a walker moving at speed v, it appears to fall obliquely, with the angle of the drops' trajectory depending on your speed. During a time period T, a raindrop travels a distance of aT. Therefore, all raindrops within a shorter distance will reach the surface: these are the drops inside a cylinder with a base of Sh and a height of aT, which gives:

> p.Sh.a.T.

>

> As we have seen, as we move forward, the drops appear to be animated by an oblique velocity that results from the composition of velocity a and velocity v. The number of drops reaching Sh remains unchanged, since velocity v is horizontal and therefore parallel to Sh. However, the number of drops reaching surface Sv -- which was previously zero when the walker was stationary -- has now increased. This is equal to the number of drops contained within a horizontal cylinder with a base area of Sv and a length of v.T. This length represents the horizontal distance the drops travel during this time interval. In total, the walker receives a number of drops given by the expression:

> p.(Sh.a + Sv.v). T

>

> Now we need to take into account the time interval during which the walker is exposed to the rain. If you're covering a distance d at constant speed v, the time you spend walking is d/v. Plugging this into the equation, the total amount of water you encounter is:

> p.(Sh.a + Sv.v). d/v = p.(Sh.a/v + Sv). d

This equation proves that the faster you move, the less water hits your head and shoulders, but the amount of water hitting the vertical part of your body remains constant. To stay drier, it's best to move quickly and lean forward. However, you'll have to increase your speed to offset the exposed surface area caused by leaning.

NASA Reveals Prototype Telescope For Gravitational Wave Observatory (phys.org)

(Wednesday October 23, 2024 @05:22PM (BeauHD) from the what-to-expect dept.)

NASA has revealed a full-scale prototype for [1]six telescopes designed to detect gravitational waves . Phys.Org reports:

> The LISA (Laser Interferometer Space Antenna) mission is led by ESA (European Space Agency) in partnership with NASA to detect gravitational waves by using lasers to measure precise distances -- down to picometers, or trillionths of a meter -- between a trio of spacecraft distributed in a vast configuration larger than the sun. Each side of the triangular array will measure nearly 1.6 million miles, or 2.5 million kilometers.

>

> The Engineering Development Unit Telescope, which was manufactured and assembled by L3Harris Technologies in Rochester, New York, arrived at Goddard in May. The primary mirror is coated in gold to better reflect the infrared lasers and to reduce heat loss from a surface exposed to cold space, since the telescope will operate best when close to room temperature.

>

> The prototype is made entirely from an amber-colored glass-ceramic called Zerodur, manufactured by Schott in Mainz, Germany. The material is widely used for telescope mirrors and other applications requiring high precision because its shape changes very little over a wide range of temperatures. The LISA mission is slated to launch in the mid-2030s.

'Electric Plastic' Could Unleash Next-Gen Implants and Wearable Tech (science.org)

(Wednesday October 23, 2024 @05:22PM (BeauHD) from the integrated-tech dept.)

An anonymous reader quotes a report from Science Magazine:

> Imagine a thin wristband that monitors your steps and heartbeat like an Apple Watch. Or clothing that keeps you cool with built-in air conditioning. Or even a flexible implant that could help your heart better than a bulky pacemaker. That's the promise of a [1]new, electrically active material researchers have created by combining short chains of amino acids called peptides with snippets of a polymer plastic. This "electric plastic," [2]reported this month in Nature , can store energy or record information, opening the door to self-powered wearables, real-time neural interfaces, and medical implants that merge with bodies better than current tech. [...]

>

> Samuel Stupp, a materials scientist at Northwestern University, and his colleagues thought they could improve on polyvinylidene fluoride's (PVDF) properties. The team connected peptides with small PVDF segments, which naturally assembled into long, flexible ribbons. The molecules then coalesced into bundles and aligned to form an electro-active material. "Remarkably," Stupp says, "the self-assembly process is triggered by adding water." The new material overcomes PVDF's limitations. It requires 100 times less voltage to switch polarization compared with other ferroelectric materials, making it ideal for low-power applications. And it retains its ferroelectric properties at temperatures of 110C -- about 40C higher than other PVDF materials.

>

> Stupp's new material can store energy or information by electrically switching the polarity of each ribbon. And because the peptide on the end of each ribbon can be connected to proteins on neurons or other cells, the molecules can record the signals from the brain, heart, or other organs -- or electrically stimulate them. By using low-power techniques like ultrasound to "charge" the molecules, the material could be used to stimulate neurons as a treatment for chronic paralysis, Stupp says. Study co-author Yang Yang, an electrical power engineer at Northwestern, notes that PVDF is biocompatible, making the material a promising candidate for soft implants that could be wirelessly controlled from outside the body.

Stupp's team has conducted small-scale evaluations of molecules, but scaling up will require placing water-suspended structures onto devices without altering them -- a challenge noted by chemist Frank Leibfarth. Even with this hurdle, "This advance has enabled a number of attractive properties compared to other organic polymers," he says.

Stupp added: "This paper has a much broader concept than just vinylidene fluoride. There probably are other possibilities ... that don't have fluorine."

UK-Based Dissident Can Sue Saudi Arabia For Alleged Spyware, Court Rules (reuters.com)

(Wednesday October 23, 2024 @11:23AM (BeauHD) from the would-you-look-at-that dept.)

A judge has [1]allowed Saudi dissident Yahya Assiri to sue the kingdom for allegedly targeting his devices with Pegasus spyware and other Israeli-made surveillance tools. Reuters reports:

> Yahya Assiri, a founder of the opposition National Assembly Party (NAAS) who lives in exile in Britain, alleges his electronic devices were targeted with surveillance software between 2018 and 2020. He is suing Saudi Arabia at London's High Court, saying the country used Pegasus - made by Israeli company NSO Group and sold only to nation states - and other spyware made by lesser-known Israeli firm QuaDream because of his work with dissidents.

>

> Earlier this month, Roger Eastman, a judge in the High Court, gave Assiri permission to serve his lawsuit on the Saudi government, a step that required the court to find Assiri has an arguable case. The decision announced on Monday to allow the case to be served on Saudi Arabia in Riyadh was made on Oct. 11. Assiri said in a statement: "I am fully aware that the authorities will want to target me. However, it is outrageous for them also to target individuals such as the victims of rights abuses and their families in Saudi Arabia simply because these people have been in contact with me."
