"Around 570 cables (plus a further 80 planned) carry between 95% and 99% of the world's intercontinental telecommunications data," reports CNN (since fiber cables offer speeds of terabits per second, carry much more data than satellite links). And "networks of green energy cables carrying electricity are also starting to sprawl across the world's seabeds." Now to protect them, the U.S., Australia and the U.K. "are planning to develop new unmanned undersea vehicles" as part of their trilateral security partnership. Western governments see a growing risk of Russian and Chinese sabotage of undersea cables and are also concerned that Iran may seek to exploit the many data networks running through the shallow waters of the Persian Gulf. The "seabed is a battlefield" said Australia's Defence Minister, Richard Marles, in Singapore, calling for tougher action against so-called shadow-fleet vessels... The programme will improve the three nations' reconnaissance and strike capabilities, "and bolster superiority in anti-submarine and anti-surface warfare," as well as mine countermeasures, [according to a statement from their trilateral AUKUS partnership]... The new AUKUS project will sharpen all three countries' ability to respond to threats, including those targeting underwater cables and pipelines, through a range of "cutting edge sensors and weapons systems for undersea drones," UK Defence Secretary John Healey said. Marles said undersea internet cables — "the arteries of modern civilization" — were being cut at an unprecedented rate, with island nations like Australia acutely vulnerable. "Over the past 18 months, we have witnessed a series of attacks against subsea critical infrastructure at a scale and frequency that is historically unprecedented," he said. The UK government has also highlighted the vulnerability of the world's digital highways. "Every international payment, every cross-border trade executed in milliseconds, every flow of data between businesses here in the UK and markets overseas — all travel along the seabed," Telecoms Minister Liz Lloyd said Friday... Last month, the UK said it had tracked three Russian submarines covertly surveying undersea cables in the north Atlantic... A UK parliamentary inquiry warned last year that UK infrastructure might be targeted in a crisis, adding it was "not confident that the UK could prevent such attacks or recover within an acceptable time period." The UK Navy is already exploring the creation of a hybrid force that incorporates the widespread use of underwater drones to combat Russian threats in the Atlantic.

An anonymous reader quotes a report from the BBC: Internet access has started to be restored in Iran after being cut off almost three months ago, the country's first vice-president has said. "The first step toward free and regulated access to cyberspace has been taken," Mohammad Reza Aref wrote on X on Tuesday. Internet monitoring groups Netblocks and Kentik reported "partial" restoration around 13:00 GMT, though the latter warned most networks were still down. The Iranian government cut internet access following the launch of US and Israeli attacks on February 28. Officials suggested the aim was to prevent surveillance, espionage and cyber-attacks. It is one of the longest-running national internet shutdowns ever recorded worldwide. A content creator from Tehran told the BBC that he had been able to connect to the internet using his home WiFi on Tuesday. "The main point is, some of my income will come back," he said. Netblocks said it was unclear whether the internet return would be sustained, and told the BBC it was consistent with what it had seen when previous blackouts were lifted -- where restoration could take hours. "Access is not universally back to its original state, with some regional variation," said the global internet tracker's research director Isik Mater on Tuesday. She added that there were signs of "more extensive filtering" than prior to January -- when a similar blackout was imposed during the regime's deadly crackdown on anti-government protests -- "including additional restrictions to messaging apps like WhatsApp."

Slashdot reader wiredmikey writes: Threat actors are exploiting a vulnerability in shared content delivery network (CDN) infrastructure to hide connections to malicious domains. Researchers say the vulnerability could impact roughly 88 million domains and can bypass DNS filtering and protective DNS controls, potentially enabling stealthy command-and-control communications and other evasive attacks. Dubbed "Underminr," the exploit "presents the SNI and HTTP Host of a domain," writes SecurityWeek, "while forcing a request to the IP address of another tenant on the same shared edge." The mismatch, ADAMnetworks reports, has been exploited in attacks targeting large-scale hosting providers, including those that have implemented mitigations against domain fronting... Threat actors' increased reliance on AI is expected to lead to a surge in attacks. "Once Underminr becomes parametric information for AI-generated malware, we could expect to see it in every attack that needs to evade protective DNS as part of the attack chain," ADAMnetworks CEO David Redekop says.

Vivaldi 8.0 is being pitched as the browser's "most significant design overhaul" yet, featuring a new unified, edge-to-edge interface, six preset layouts, and deeper customization across tabs, toolbars, panels, and themes. The company is also taking a swipe at rivals chasing questionable AI features. Neowin reports: After updating to version 8.0, Vivaldi will present you with the ability to select one of the six pre-built styles. You can select a minimal edge-to-edge theme, one with the UI fully hidden for focused work, or a power user variant with everything on the screen. The update comes with a built-in collection theme, and users are free to select one of over 7,000 community themes available on the official website. Vivaldi says that while other browsers were busy adding questionable AI features, it focused on "a foundation that no other browser can match" with flexible tab management, built-in productivity tools, and advanced customization. At the same time, Vivaldi does not force the new design onto its users, so those who prefer the previous user interface can go back to it at any moment in settings. "With 8.0, we have done something we have been working toward for a long time: we have given the browser itself a visual system worthy of everything it can do," says Vivaldi's CEO and co-founder, Jon Stephenson von Tetzchner. "With this update Vivaldi feels like one considered, coherent tool." You can download Vivaldi 8.0 and view the changelog at their respective links.

Iran's government "wants to charge the world's largest tech companies for using the subsea internet cables laid under the Strait of Hormuz," reports CNN. Their article also notes that Iran's state-linked media outlets "have vaguely threatened that traffic could be disrupted if firms don't pay." Lawmakers in Tehran discussed a plan last week which could target submarine cables linking Arab countries to Europe and Asia. "We will impose fees on internet cables," Iranian military spokesperson Ebrahim Zolfaghari declared on X last week. Iran's Revolutionary Guards-linked media said Tehran's plan to extract revenue from the strait would require companies like Google, Microsoft, Meta, and Amazon to comply with Iranian law while submarine cable companies would be required to pay licensing fees for cable passage, with repair and maintenance rights given exclusively to Iranian firms. Some of these companies have invested in the cables running through the Strait of Hormuz and the Persian Gulf, but it's unclear if those cables traverse Iranian waters. It's also unclear how the regime could force tech giants to comply, as they are barred from making payments to Iran due to strict US sanctions; as a result, the companies themselves may view Iran's statements as posturing rather than serious policy. Still, state-affiliated media outlets have issued veiled threats warning of damage to cables that could impact some of the trillions of dollars in global data transmission and affect worldwide internet connectivity... Iran's threats are part of a strategy to demonstrate its leverage over the Strait of Hormuz and ensure the survival of the regime, a core objective for the Islamic Republic in this war, said Dina Esfandiary, Middle East lead at Bloomberg Economics. "It aims to impose such a hefty cost on the global economy that no-one will dare attack Iran again," she said. The article notes that subsea cables "carry vast internet and financial traffic between Europe, Asia and the Persian Gulf," and that targetting them "would affect far more than internet speeds, threatening everything from banking systems, military communications and AI cloud infrastructure to remote work, online gaming and streaming services." CNN spoke to Mostafa Ahmed, "a senior researcher at the United Arab Emirates-based Habtoor Research Center, who published a paper on the effects of a large-scale attack on submarine communications infrastructure in the Gulf." Armed with combat divers, small submarines, and underwater drones, the Islamic Revolutionary Guard Corps (IRGC) poses a risk to underwater cables, Ahmed said, adding that any attack could trigger a cascading "digital catastrophe" across several continents. Iran's neighbors across the Persian Gulf could face severe disruptions to internet connection, potentially impacting critical oil and gas exports as well as banking. Beyond the region, India could see a large proportion of its internet traffic affected, threatening its huge outsourcing industry with losses amounting to billions, according to Ahmed... Any disruption could also slow financial trading and cross-border transactions between Europe and Asia, while parts of East Africa could face internet blackouts. And if Iran's proxies decide to employ similar tactics in the Red Sea, the damage could be far worse.

A new Internet Matters survey suggests the UK's Online Safety Act age checks are easy for many children to bypass. Reported workarounds include fake birthdays, borrowed IDs, video game characters, and even drawing on a fake mustache. The Register reports: The group surveyed over 1,000 UK children and their parents, and while it did report some positive effects from changes made under the OSA, many children saw age verification as an easy-to-bypass hurdle rather than something that kept them genuinely safe. A full 46 percent of children even said that age checks were easy to bypass, while just 17 percent said that they were difficult to fool. The methods kids use to fool age gates vary, but most are pretty simple: There's the classic use of a video game character to fool video selfie systems, while in other instances, children reported just entering a fake birthday or using someone else's ID card when that was required. The report even cites cases of children drawing a mustache on their faces to fool age detection filters. Seriously. While nearly half of UK kids say it's easy to bypass online age checks (and another 17 percent say it's neither hard nor easy), only 32 percent say they've actually bypassed them, according to Internet Matters. Like scoring some booze from "cool" parents, keeping age-gated content out of the hands of kids under the OSA is only as effective as parents let it be, and a quarter of them enable their kids' online delinquency. More specifically, Internet Matters found that a full 17 percent of parents admitted to actively helping their kids evade age checks, while an additional 9 percent simply turned a blind eye to it.

An anonymous reader shared this report from the BBC: "If even one extra person is able to access the internet, I think it's successful and it's worth it," says Sahand. The Iranian man is visibly anxious, speaking to the BBC outside Iran, as he carefully explains how he is part of a clandestine network smuggling satellite internet technology — which is illegal in Iran — into the country. Sahand, whose name we have changed, fears for family members and other contacts inside the country. "If I was identified by the Iranian regime, they might make those I'm in touch with in Iran pay the price," he says. For more than two months, Iran has been in digital darkness as the government maintains one of the longest-running national internet shutdowns ever recorded worldwide... Sahand says he has sent a dozen [Starlink terminals] to Iran since January and "we are actively looking for other ways to smuggle in more". The human rights organisation Witness estimated in January that there are at least 50,000 Starlink terminals in Iran. Activists say the number is likely to have risen... Last year, the Iranian government passed legislation that made using, buying or selling Starlink devices punishable by up to two years in prison. The jail term for distributing or importing more than 10 devices can be up to 10 years. State-affiliated media has reported multiple cases of people being arrested for selling and buying Starlink terminals, including four people — two of them foreign nationals — arrested last month for "importing satellite internet equipment". "The BBC contacted SpaceX for more details about the use of Starlink in the country but did not receive a response."

ICANN has opened applications for new generic top-level domains for the first time since 2012. The Register reports: ICANN hasn't offered new gTLDs since 2012, but on Thursday opened applications for new domains in 27 scripts. A 439-page Applicant Guidebook explains the process. The Register suggests paying attention to the string evaluation FAQ, which explains which gTLDs are valid, and those ICANN will likely frown upon. An FAQ describes this round of applications as giving "businesses, communities, and others the opportunity to apply for new top-level domains tailored to their community, culture, language, business, and customers." "A TLD can be a branding opportunity for a business, but the commercial opportunities are endless, allowing businesses in countries, entire sectors, or niche markets to develop a unique label on the Internet." ICANN also sees this round as a chance to "create a more multilingual Internet for the billions of people who speak and write in different languages and scripts and are yet to come online." If you fancy a gTLD, you'll need to pay a $227,000 application fee by August 12th ... and then wait, possibly until 2030 when this process ends.

alternative_right shares a report from 404 Media: Researchers working with data from the Internet Archive have discovered that a third of websites created since 2022 are AI-generated. The team of researchers -- which includes people from Stanford, the Imperial College London, and the Internet Archive -- published their findings online in a paper titled "The Impact of AI-Generated Text on the Internet." The research also found that all this AI-generated text is making the web more cheery and less verbose."The proliferation of AI-generated and AI-assisted text on the internet is feared to contribute to a degradation in semantic and stylistic diversity, factual accuracy, and other negative developments," the researchers write in the paper. "We find that by mid-2025, roughly 35% of newly published websites were classified as AI-generated or AI-assisted, up from zero before ChatGPT's launch in late 2022." "I find the sheer speed of the AI takeover of the web quite staggering," Jonas Dolezal, an AI researcher at Stanford and co-author of the paper, told 404 Media. "After decades of humans shaping it, a significant portion of the internet has become defined by AI in just three years. We're witnessing, in my opinion, a major transformation of the digital landscape in a fraction of the time it took to build in the first place." Maty Bohacek, a student researcher at Stanford and one of the co-authors of the paper, added: "As AI-generated content spreads, the challenge is finding a role for these models that doesn't just result in a sanitized, repetitive web," he said. "Rather than forcing models to be perfectly compliant and agreeable, allowing them to have a more distinct personality or 'friction' might help them act as a creative partner rather than a replacement for human voice."

Longtime Slashdot reader mmarlett writes: The Atlantic has a long article on the story of missing scientists recently featured here on Slashdot. In short, it is an incoherent conspiracy theory that spreads wide and far, not paying any attention to boundaries of time, space, or area of expertise. "Which is all to say that another piece of flagrant nonsense has ascended to the highest levels of U.S. politics and media," writes the Atlantic's Daniel Engber. "To call it a conspiracy theory would be far too kind, because no comprehensive theory has been floated to explain the pattern of events. But then, even the phrase pattern of events is imprecise, because there is no pattern here at all. Given all the people who could have been roped into this narrative but weren't, any hope of finding meaning falls away. Barring any dramatic new disclosures, the mystery of the missing scientists has the dubious honor of being a sham in every way at once."

IPv6 usage briefly reached 50% across Google services for the first time, marking a major milestone for a protocol created in 1998 to solve IPv4's address shortage. Tom's Hardware reports: [...] IPv6 was dismissed early on as a headache-inducing, hard-to-implement complication that would hardly ever gain any traction -- despite offering 2^128 possible numbers, solving all network number assignments in one fell swoop. That changed over time by force of necessity, and Google's tracking graph shows that for a brief moment in time on March 28, 50% of worldwide users accessed the service over an IPv6 connection, marking a historic first. APNIC's stats show that the protocol is in use by 43% of the world, with Asia and the Americas inching ever close to those 50%. Cloudflare, meanwhile, shows that 40% of traffic is done in IPv6, an actually impressive figure if you consider it's measuring actual transferred packets rather than just counting addresses. The tried-and-true IPv4 and its well-known 123.456.789.123 format from 1980 offers ~4.3 billion addresses in theory, and around 3.7 billion in practice. That always sounded like a lot, but nobody could have predicted just how rapid the explosion of the Internet would be. IANA, the entity controlling the North-American IPv4 space, ran out of IPv4 addresses around 2011, while its European equivalent RIPE NCC could spare no more four-octet addresses nearly seven years ago in 2019. Asian, African, and Latin-American IP registries equally ran out during that timeframe.
