Three years ago security researcher Eaton Zveare discovered a vulnerability in Jacuzzi's SmartTub interface allowing access to the personal data of every hot tub owner.

Now Zverae says flaws in an unnamed carmaker's dealership portal "exposed the private information and vehicle data of its customers," reports TechCrunch, "and could have allowed hackers to remotely break into any of its customers' vehicles." Zveare, who works as a security researcher at software delivery company Harness, told TechCrunch the flaw he discovered allowed the creation of a ["national"] admin account that granted "unfettered access" to the unnamed carmaker's centralized web portal. With this access, a malicious hacker could have viewed the personal and financial data of the carmaker's customers, tracked vehicles, and enrolled customers in features that allow owners — or the hackers — to control some of their cars' functions from anywhere.

Zveare said he doesn't plan on naming the vendor, but said it was a widely known automaker with several popular sub-brands.

In an interview with TechCrunch ahead of his talk at the Def Con security conference in Las Vegas on Sunday, Zveare said the bugs put a spotlight on the security of these dealership systems, which grant their employees and associates broad access to customer and vehicle information... The flaws were problematic because the buggy code loaded in the user's browser when opening the portal's login page, allowing the user — in this case, Zveare — to modify the code to bypass the login security checks. Zveare told TechCrunch that the carmaker found no evidence of past exploitation, suggesting he was the first to find it and report it to the carmaker.

When logged in, the account granted access to more than 1,000 of the carmakers' dealers across the United States, he told TechCrunch... With access to the portal, Zveare said it was also possible to pair any vehicle with a mobile account, which allows customers to remotely control some of their cars' functions from an app, such as unlocking their cars... "The takeaway is that only two simple API vulnerabilities blasted the doors open, and it's always related to authentication," said Zveare. "If you're going to get those wrong, then everything just falls down."
Zveare told TechCrunch the portals even included "telematics systems that allowed the real-time location tracking of rental or courtesy cars...

"Zveare said the bugs took about a week to fix in February 2025 soon after his disclosure to the carmaker."

"Several cybersecurity companies debuted advancements in AI agents at the Black Hat conference last week," reports Axios, "signaling that cyber defenders could soon have the tools to catch up to adversarial hackers." - Microsoft shared details about a prototype for a new agent that can automatically detect malware — although it's able to detect only 24% of malicious files as of now.

- Trend Micro released new AI-driven "digital twin" capabilities that let companies simulate real-world cyber threats in a safe environment walled off from their actual systems.

- Several companies and research teams also publicly released open-source tools that can automatically identify and patch vulnerabilities as part of the government-backed AI Cyber Challenge.

Yes, but: Threat actors are now using those AI-enabled tools to speed up reconnaissance and dream up brand-new attack vectors for targeting each company, John Watters, CEO of iCounter and a former Mandiant executive, told Axios.
The article notes "two competing narratives about how AI is transforming the threat landscape." One says defenders still have the upper hand. Cybercriminals lack the money and computing resources to build out AI-powered tools, and large language models have clear limitations in their ability to carry out offensive strikes. This leaves defenders with time to tap AI's potential for themselves. [In a DEF CON presentation a member of Anthropic's red team said its Claude AI model will "soon" be able to perform at the level of a senior security researcher, the article notes later]

Then there's the darker view. Cybercriminals are already leaning on open-source LLMs to build tools that can scan internet-connected devices to see if they have vulnerabilities, discover zero-day bugs, and write malware. They're only going to get better, and quickly...

Right now, models aren't the best at making human-like judgments, such as recognizing when legitimate tools are being abused for malicious purposes. And running a series of AI agents will require cybercriminals and nation-states to have enough resources to pay the cloud bills they rack up, Michael Sikorski, CTO of Palo Alto Networks' Unit 42 threat research team, told Axios. But LLMs are improving rapidly. Sikorski predicts that malicious hackers will use a victim organization's own AI agents to launch an attack after breaking into their infrastructure.

Croatia has extended its digital nomad visa from one year to up to three years, allowing non-EU residents and their close family members to live and work remotely in the country. CNBC reports: A digital nomad visa is a short-term permit that allows individuals to stay in a country for an extended period and work remotely. The length of time a nomad can stay varies from place to place but most countries allow for six months to a year -- unless you have your eye on Croatia. Recently, the Balkan country announced it an update its digital nomad visa, which will allow non-EU residents to stay for up to three years. The visa also permits close family members of a digital nomad to join them.

Croatia's digital nomad visa website states that close family members also include partners or non-married couples who have been together for longer than three years without children, or for less time if they do have children together. Madrid Sartoretto believes that Croatia's expansion of its digital nomad program is a sign that the country is trying to attract more talent and compete with neighboring countries and their offerings.

"I think they are competing with other countries that are in the same region, like Estonia and Romania, that also attract a lot of digital nomads. If you give more benefits to people to come to your country, then you attract more talent. It's all about competition now," she adds. For those looking to apply for Croatia's digital nomad visa, Dr. Madrid Sartoretto says the country offers a low cost of living but still needs to improve its infrastructure, like more reliable internet speeds. "If you compare internet speed and reliability to countries like Romania, which has one of the fastest speeds in the world, Croatia needs to improve its infrastructure," she adds.

To apply for Croatia's digital nomad visa online, applicants must provide proof that they work outside of Croatia. Additionally, they must provide a copy of a valid travel document, proof of health insurance, proof of address in Croatia, and a minimum monthly income of 3,295 euros or $3,855 USD. For proof of income, applicants can submit a bank statement showing the total amount required, a bank statement demonstrating regular income, or pay slips for at least six months. Applicants must also send evidence that they have not been convicted of criminal offences in their home country or the country in which they have resided for more than a year immediately before arriving in Croatia.

OpenAI CEO Sam Altman told reporters that AI investments have entered bubble territory. His remarks: "Are we in a phase where investors as a whole are overexcited about AI? My opinion is yes."

"When bubbles happen, smart people get overexcited about a kernel of truth. If you look at most of the bubbles in history, like the tech bubble, there was a real thing. Tech was really important. The internet was a really big deal. People got overexcited."

He added that he thinks it's "insane" that some AI startups with "three people and an idea" are receiving funding at such high valuations. "That's not rational behavior," Altman said. "Someone's gonna get burned there, I think. Someone is going to lose a phenomenal amount of money."

Russian authorities are "partially" restricting calls in messaging apps Telegram and WhatsApp, the latest step in an effort to tighten control over the internet. From a report: In a statement, government media and internet regulator Roskomnadzor justified the measure as necessary for fighting crime, saying that "according to law enforcement agencies and numerous appeals from citizens, foreign messengers Telegram and WhatsApp have become the main voice services used to deceive and extort money, and to involve Russian citizens in sabotage and terrorist activities."

After four weather-related delays, Amazon successfully launched 24 more Kuiper internet satellites aboard a SpaceX Falcon 9, bringing its total to 102. CNBC reports: SpaceX's Starlink is currently the dominant provider of low-earth orbit satellite internet, with a constellation of roughly 8,000 satellites and about 5 million customers worldwide. Amazon is racing to get more of its Kuiper satellites into space to meet a deadline set by the Federal Communications Commission. The FCC requires that Amazon have about 1,600 satellites in orbit by the end of July 2026, with the full 3,236-satellite constellation launched by July 2029.

Amazon has booked up to 83 launches, including three rides with SpaceX. While the company is still in the early stages of building out its constellation, Amazon has already inked deals with governments as it hopes to begin commercial service later this year.

Reddit says that it has caught AI companies scraping its data from the Internet Archive's Wayback Machine, so it's going to start blocking the Internet Archive from indexing the vast majority of Reddit. From a report: The Wayback Machine will no longer be able to crawl post detail pages, comments, or profiles; instead, it will only be able to index the Reddit.com homepage, which effectively means Internet Archive will only be able to archive insights into which news headlines and posts were most popular on a given day.

"Internet Archive provides a service to the open web, but we've been made aware of instances where AI companies violate platform policies, including ours, and scrape data from the Wayback Machine," spokesperson Tim Rathschmidt tells The Verge.

In 2020 a YouTube video used video footage of Steve Wozniak in a scam to steal bitcoin. "Some people said they lost their life savings," Wozniak tells CBS News, explaining why he sued YouTube in 2020 — and where his case stands now: Wozniak's lawsuit against YouTube has been tied up in court now for five years, stalled by federal legislation known as Section 230. Attorney Brian Danitz said, "Section 230 is a very broad statute that limits, if not totally, the ability to bring any kind of case against these social media platforms."

"It says that anything gets posted, they have no liability at all," said Wozniak. "It's totally absolute."

Google responded to our inquiry about Wozniak's lawsuit with a statement from José Castañeda, of Google Policy Communications: "We take abuse of our platform seriously and take action quickly when we detect violations ... we have tools for users to report channels that are impersonating their likeness or business." [Steve's wife] Janet Wozniak, however, says YouTube did nothing, even though she reported the scam video multiple times: "You know, 'Please take this down. This is an obvious mistake. This is fraud. You're YouTube, you're helping dupe people out of their money,'" she said.

"They wouldn't," said Steve...
Today is Steve Wozniak's 75th birthday. (You can watch the interview here.) And the article includes this interesting detail about Woz's life today: Wozniak sold most of his Apple stock in the mid-1980s when he left the company. Today, though, he still gets a small paycheck from Apple for making speeches and representing the company. He says he's proud to see Apple become a trillion-dollar company. "Apple is still the best," he said. "And when Apple does things I don't like, and some of the closeness I wish it were more open, I'll speak out about it. Nobody buys my voice!"

I asked, "Apple listen to you when you speak out?"

"No," Wozniak smiled. "Oh, no. Oh, no."
Wozniak answered questions from Slashdot readers in 2000 and again in 2012.

And he dropped by Slashdot on his birthday to leave this comment for Slashdot's readers...

AOL (now a Yahoo subsidiary) just announced its dial-up internet service will be discontinued at the end of September.

"The change also means the retirement of the AOL Dialer software and the AOL Shield browser, both designed for older operating systems and slow connections that relied on the familiar screech of a modem handshake," remembers Slashdot reader BrianFagioli (noting that dial-up Internet "was once the gateway to the web for millions of households, back when speeds were measured in kilobits and waiting for a picture to load could feel like an eternity.")

AOL's dial-up service "has been publicly available for 34 years," writes Tom's Hardware. But AppleInsider notes the move comes more than 40 years after AOL started "as a very early Apple service." AOL itself started back in 1983 under the name Control Video Corporation, offering online services for the Atari 2600 console. After failing, it became Quantum Computer Services in 1985, eventually launching AppleLink in 1988 to connect Macintosh computers together... With the launch of PC Link for IBM-compatible PCs in 1988 and parting from Apple in October 1989, the company rebranded itself as America Online, or AOL... Even at its height, dial-up connections could get up to 56 kilobits per second under ideal conditions, while modern connections are measured in megabits and gigabits. Most of the service was also what's considered a "walled garden," with features that were only available through AOL itself and that it wasn't the actual, untamed Internet.
In the 1990s AOL "was how millions of people were introduced to the Internet," the article remembers, adding that "Even after the AOL Time Warner acquisition and the 2015 acquisition by Verizon, AOL was still a popular service. Astoundingly, it counted about two million dial-up subscribers at the time." In the 2021 acquisition of assets from Verizon by Apollo Global Management, AOL was said to have 1.5 million people paying for services. However, this was more for technical support and software, rather than for actual Internet access. A CNBC report at the time reports that the dial-up user count was "in the low thousands".... While it dies off, not with a bang but a whimper, AOL's dial-up is still remembered as one of the most transformative services in the Internet age.
"This change does not impact the numerous other valued products and services that these subscribers are able to access and enjoy as part of their plans," a Yahoo spokesperson told PC Magazine this week. "There is also no impact to our users' free AOL email accounts." AOL's disastrous 2001 merger with Time Warner and ongoing inability to deliver broadband to its customers... left it on a path to decline that acquiring such widely read sites as Engadget [2005] and TechCrunch [2010] did not stem. By 2014, the number of dial-up AOL customers had collapsed to 2.34 million. A year later, Verizon bought the company for $4.4 billion in an internet-content play that turned out to be as doomed as the Time Warner transaction. In 2021, Verizon unloaded both AOL and Yahoo, which it had separately purchased in 2017, to the private-equity firm Apollo Global Management....

The demise of AOL's dial-up service does not mean the extinction of the oldest form of consumer online access. Estimates from the Census Bureau's 2023 American Community Survey show 163,401 Americans connected to the internet via dial-up that year.

That was by far the smallest segment of the internet-using population, dwarfed by 100,166,949 subscribing to such forms of broadband as "cable, fiber optic, or DSL"; 8,628,648 using satellite; 3,318,901 using "Internet access without a subscription" (which suggests Wi-Fi from coffee shops or public libraries); and 1,445,135 via "other service."

The remaining AOL dial-up subscribers will need to find some sort of replacement, which in rural areas may be limited to fixed wireless or SpaceX's considerably more expensive Starlink. Or they may wind up joining the ranks of Americans with no internet access: 6,866,059, in those 2023 estimates.

Advocacy groups have decided not to appeal a federal court ruling striking down Biden-era net neutrality rules, citing the FCC's current Republican majority and a Supreme Court they view as hostile to the issue. Instead, they plan to push for open internet protections through Congress, state laws, and future court cases, while noting California's net neutrality law remains in effect. Ars Technica reports: "Trump's election flipped the FCC majority back to ideologues who've always taken the broadband industry's side on this crucial issue. And the justices making up the current Supreme Court majority have shown hostility toward sound legal reasoning on this precise question and a host of other topics too," said Matt Wood, VP of policy and general counsel at Free Press. [...] "The 6th Circuit's decision earlier this year was spectacularly wrong, and the protections it struck down are extremely important. But rather than attempting to overcome an agency that changed hands -- and a Supreme Court majority that cares very little about the rule of law -- we'll keep fighting for Internet affordability and openness in Congress, state legislatures and other court proceedings nationwide," Wood said.

Besides Free Press, groups announcing that they won't appeal are the Benton Institute for Broadband & Society, New America's Open Technology Institute, and Public Knowledge. "Though the 6th Circuit erred egregiously in its decision to overturn the FCC's 2024 Open Internet order, there are other ways we can advance our fight for consumer protections and ISP accountability than petitioning the Supreme Court to review this case -- and, given the current legal landscape, we believe our efforts will be more effective if focused on those alternatives," said Raza Panjwani, senior policy counsel at the Open Technology Institute. Net neutrality could still reach the Supreme Court in another case. Andrew Jay Schwartzman, senior counselor of the Benton Institute for Broadband & Society, said that "the 6th Circuit decision makes bad policy as well as bad law. Because it is at odds with the holdings of two other circuits, we expect to take the issue to the Supreme Court in a future case."

An anonymous reader quotes a report from 404 Media: Some of the first reviews ever written for the original Legend of Zelda and Super Mario Bros. have been digitized and published by the Video Game History Foundation. The reviews appeared in Computer Entertainer, an early video game magazine that ran from 1982 to 1990. The archivists at the Foundation tracked down the magazine's entire run and have published it all online under a Creative Commons license.

An anonymous reader quotes a report from Ars Technica: The Library of Congress today said a coding error resulted in the deletion of parts of the US Constitution from Congress' website and promised a fix after many Internet users pointed out the missing sections this morning. The missing portions of the Constitution were restored to one part of the website a few hours after the Library of Congress statement and reappeared on a different part of the website another hour or so later. The Constitution Annotated website carried a notice saying it "is currently experiencing data issues. We are working to resolve this issue and regret the inconvenience."

"Upkeep of Constitution Annotated and other digital resources is a critical part of the Library's mission, and we appreciate the feedback that alerted us to the error and allowed us to fix it," the Library of Congress said. We asked the Library of Congress for specific details on the coding error, but we received only a statement that did not include specifics. "Due to a technical error, some sections of Article 1 were temporarily missing on the Constitution Annotated website. This problem has been corrected, and the missing sections have been restored," the statement said.

The deletion happened sometime in the past few weeks, as an Internet Archive capture shows that the text was still on the site until at least July 21. The deletions were being discussed this morning on Reddit and in news articles, with people expressing suspicions based on which parts of the Constitution were missing.

Jim Acosta, the former CNN chief White House correspondent who now hosts an independent show on YouTube, has interviewed an AI-generated avatar of Parkland shooting victim Joaquin Oliver. The late teen's parents created the avatar to preserve his voice and advocate for gun reform. Oliver's parents "granted Acosta the first 'interview' with the recreated version of their son on what would have been his 25th birthday," notes Variety. "Oliver was one of 17 people killed in the mass shooting at Marjory Stoneman Douglas High School." From the report: Acosta asked AI Oliver about his solution for gun violence, to which the avatar responded: "I believe in a mix of stronger gun control laws, mental health support and community engagement. We need to create safe spaces for conversations and connections, making sure everyone feels seen and heard. It's about building a culture of kindness and understanding." The avatar added, "Though my life was cut short, I want to keep inspiring others to connect and advocate for change." Acosta then asked AI Oliver about his personal life, such as his favorite sport and favorite basketball team. The two discussed the movie "Remember the Titans" and their favorite "Star Wars" moments.

After a five-minute chat with the AI, Acosta then connected with Oliver's father, Manuel Oliver. "I'm kind of speechless as to the technology there," Acosta said. "It was so insightful. I really felt like I was speaking with Joaquin. It's just a beautiful thing." Manuel, who has been an outspoken voice in the push for gun control, said he believed bringing "AI Joaquin to life" would "create more impact." According to Manuel, the avatar is trained on information on the internet as well as things Oliver wrote, said and posted online. He said he wanted to make it clear to viewers that he is under no illusions about reviving his son. "I understand that this is AI. I don't want anyone to think that I am, in some way, trying to bring my son back," he said. "Sadly, I can't, right? I wish I could. However, the technology is out there." [...]

Manuel said he is excited about the future of the project and what it means for his son's legacy. "What's amazing about this is that we've heard from the parents, we've heard from the politicians. Now we're hearing from one of the kids," Acosta said. "That's important. That hasn't happened." Manuel said he plans to have AI Oliver "on stage in the middle of a debate," and that "his knowledge is unlimited." You can watch the full interview on YouTube.

In a report published Monday, Cloudflare accused Perplexity of deploying undeclared web crawlers that masquerade as regular Chrome browsers to access content from websites that have explicitly blocked its official bots. Since then, Perplexity has publicly and loudly announced that Cloudflare's claims are baseless and technically flawed. "This controversy reveals that Cloudflare's systems are fundamentally inadequate for distinguishing between legitimate AI assistants and actual threats," says Perplexity in a blog post. "If you can't tell a helpful digital assistant from a malicious scraper, then you probably shouldn't be making decisions about what constitutes legitimate web traffic."

Perplexity continues: "Technical errors in Cloudflare's analysis aren't just embarrassing -- they're disqualifying. When you misattribute millions of requests, publish completely inaccurate technical diagrams, and demonstrate a fundamental misunderstanding of how modern AI assistants work, you've forfeited any claim to expertise in this space."

Longtime Slashdot reader SonicSpike shares a report from TechCrunch: Sarah Murray recalls the first time she saw an artificial model in fashion: It was 2023, and a beautiful young woman of color donned a Levi's denim overall dress. Murray, a commercial model herself, said it made her feel sad and exhausted. The iconic denim company had teamed up with the AI studio Lalaland.ai to create "diverse" digital fashion models for more inclusive ads. For an industry that has failed for years to employ diverse human models, the backlash was swift, with New York Magazine calling the decision "artificial diversity."

"Modeling as a profession is already challenging enough without having to compete with now new digital standards of perfection that can be achieved with AI," Murray told TechCrunch. Two years later, her worries have compounded. Brands continue to experiment with AI-generated models, to the consternation of many fashion lovers. The latest uproar came after Vogue's July print edition featured a Guess ad with a typical model for the brand: thin yet voluptuous, glossy blond tresses, pouty rose lips. She exemplified North American beauty standards, but there was one problem -- she was AI generated.

The internet buzzed for days, in large part because the AI-generated beauty showed up in Vogue, the fashion bible that dictates what is and is not acceptable in the industry. The AI-generated model was featured in an advertisement, not a Vogue editorial spread. And Vogue told TechCrunch the ad met its advertising standards. To many, an ad versus an editorial is a distinction without a difference. TechCrunch spoke to fashion models, experts, and technologists to get a sense of where the industry is headed now that Vogue seems to have put a stamp of approval on technology that's poised to dramatically change the fashion industry. Amy Odell, a fashion writer and author of a recently published biography on Gwyneth Paltrow, put it simply: "It's just so much cheaper for [brands] to use AI models now. Brands need a lot of content, and it just adds up. So if they can save money on their print ad or their TikTok feed, they will."

An anonymous reader quotes a report from NPR: Patrick Schlott often finds himself in a cellular dead zone during his drive to work. "You go down the road, you turn the corner and you're behind a mountain and you'll lose cell coverage pretty fast," he says. The 31-year-old electrical engineer says poor reception is a common frustration for residents of Vermont's Orange County. To address this issue, he's providing his community with a new way to stay connected.

Schlott has taken old pay phones, modified them to make free calls, and set them up in three different towns across the county. He buys the phones secondhand from sites like eBay and Craigslist and restores them in his home workshop. With just an internet connection, these phones can make calls anywhere in the U.S. or Canada -- no coins required. And Schlott covers all the operating costs himself. "It's cheap enough where I'm happy just footing the bill," he says. "You know, if I'm spending $20 a month on, say, Netflix, I could do that and provide phone service for the community. And to me, that's way more fun." Hundreds of calls have been made since the first phone was installed back in March last year. "I knew there would be some fringe cases where it would be really helpful," says Schlott. "But I never expected it to get daily use and for people to be this excited about it."

"One of the cornerstones that I want to stick to is, no matter what happens on the backend, the calls will always be free," he says. "And I will figure out a way to make that happen."

AI startup Perplexity is deploying undeclared web crawlers that masquerade as regular Chrome browsers to access content from websites that have explicitly blocked its official bots, according to a Cloudflare report published Monday. When Perplexity's declared crawlers encounter robots.txt restrictions or network blocks, the company switches to a generic Mozilla user agent that impersonates "Chrome/124.0.0.0 Safari/537.36" running on macOS, the web infrastructure firm reported.

Cloudflare engineers tested the behavior by creating new domains with robots.txt files prohibiting all automated access. Despite the restrictions, Perplexity provided detailed information about the protected content when queried, while the stealth crawler generated 3-6 million daily requests across tens of thousands of domains. The undeclared crawler rotated through multiple IP addresses and network providers to evade detection.

Started in 1984, it's been described as the internet's longest-running contest. And yesterday 2025's International Obfuscated C Code Contest concluded — with 23 new winners announced in a special four-and-a-half-hour livestreamed ceremony!

Programmers submitted their funniest programs showcasing C's unusual/obscure subtleties while having some fun. (And demonstrating the importance of clarity and style by setting some very bad examples...) Among this year's winners were an OpenRISC 32-bit CPU emulator, a virtual machine capable of running Doom, and some kind of salmon recipe that makes clever use of C's U"string" literal prefix...

But yes, every entry's source code is ridiculously obfuscated. ("Before you set off on your adventure to decode this program's logic, make sure you have enough food, ammo, clothes, oxen, and programming supplies," read the judge's remarks on the winner of this year's "diabolical logistics" prize. "You'll be driving for 2170 miles through a wild wilderness inspired by Oregon Trail...") And one entrant also struggled mightily in adapting a rough port of their program's old Atari 2600 version, but was never gonna give it up...

Thanks to long-time Slashdot reader achowe for bringing the news (who has submitted winning entries in four different decades, starting in 1991 and continuing through 2024)...

Including a 2004 award for the best abuse of the contest's guidelines. ("We are not exactly sure how many organisations will be upset with this entry, but we are considering starting an IOCCC standards body just to reign in the likes of Mr Howe....")

A Brussels court has issued an unusually broad site-blocking order targeting Internet Archive's Open Library alongside shadow libraries including Anna's Archive, Libgen, and Z-Library. The order, requested by publishing and author organizations, directs an unprecedented range of intermediaries to take action beyond traditional ISP blocks.

Search engines, DNS resolvers, advertisers, domain name services, CDNs, hosting companies, and payment processors -- including Google, Microsoft, Cloudflare, Amazon Web Services, PayPal, and Starlink -- must restrict access to the targeted sites. The court found "clear and significant infringement" in the ex parte proceeding.

BrianFagioli writes: Google is changing its mind about killing off all goo.gl short links. The company had originally planned to shut them down entirely by August 25, 2025. That decision sparked concern among developers, educators, journalists, and everyday users who rely on these links across the web.

Now, just weeks before the deadline, Google is taking a softer approach. It turns out the company is only going to disable goo.gl links that haven't seen any activity since late 2024. If your link is still being used or clicked, it should keep working. This adjustment comes after what Google describes as community feedback.
