Reuters reports: Liquid Network, a Bitcoin-based payments and settlement network, said on Sunday that about $320 million was withdrawn from its federation wallet in a hack. "Purported white-hat hackers" withdrew around 4,000 of the 4,200 bitcoin held in its Liquid Federation wallet, Liquid Network said in a post on X. "Liquid wallets will be impacted," their post concluded, adding "and we're sorry for any inconvenience."

A new streaming TV channel shows films made with genAI, reports Engadget. "Fairground AI Creator TV" is free — and supported with ads — describing its material as "AI Cinema": "AI-generated" can make it sound as though someone typed a sentence into a machine and came back five minutes later to find a finished movie. Fairground's catalog shows why that description can be too simple. Take Lost Garden: The Awakening of the Lantern Knight. According to its Fairground page, creator Frank Houbre wrote the world, characters, mythology, emotional arc and screenplay himself. AI tools were used mainly for animation and visual production, with other tools helping create voices and music before the episode was assembled in conventional video-editing software. There's still one question, the article notes: "whether viewers actually want an AI-focused TV channel." More than 100 AI creators have contributed to the 24-hour slate of programming, although Variety points out several of them were discovered on social media. The channel was recently profiled in an article by the Guardian. Its headline? "'Nightmare fodder': Roku's AI slop channel is even worse than expected." (And its subheading calls it "a 24/7 channel devoted to low-quality AI content for viewers sick of watching real people move...") What about people who hate plot and vision and the sight of people speaking convincing dialogue that synchronises perfectly with the movement of their lips? What about the people who just want to watch an unyielding torrent of eerily weightless nightmare fodder? Well, good news. Roku has finally caught up... Early reactions were, to put it mildly, not great. The Verge compared it to eating from a trough, while Futurism called it "bottom-of-the-barrel slop"... On the plus side, the channel is evidence that artificial intelligence has come on in leaps and bounds over the last couple of years... However, it is still awful. Categorically, catastrophically awful. The channel doesn't so much offer shows as a drifting dreamscape of bad ideas rendered as horribly as possible with no thought paid to scheduling. At one point on Wednesday, a shrill high-frequency anime gave way to a long and staid German-language short about Nazi bureaucracy. After that came a sort of Gladiator ripoff that had all the dynamism of an exhibit you'd see at the fourth-best museum on a poorly planned family holiday.

Slashdot reader DeanonymizedCoward writes: Reuters reports that the US Military is disabling ad tracking on devices, to prevent adversaries from buying publicly-available tracking data to assist in targeting troops. Military officials say that they have disabled trackers on a variety of computers and mobile devices, according to letters released on Friday by Sen. Ron Wyden, and following reports that commercially-available tracking data has been used to target troops in the Middle East.... Wyden said in a statement that it was clear that the military's efforts "have not been effective at neutralizing this threat." U.S. Representative Pat Harrigan, a North Carolina Republican, said that U.S. enemies "should not be able to pull out a credit card and buy information that helps them track American troops." Rep. Harrigan remains silent as to the larger question of whether the general public should be able to pull out a credit card and buy information that helps them track anyone they please. "The Pentagon said in an email it would respond to the lawmakers directly," Reuters reports: The Army said in a statement that advertising IDs had been blocked on Windows computers "since before 2021" but that Android and Apple mobile devices had only had it disabled by default "since at least February 2026...." The effort to reduce the location data generated by smartphones comes as military officials weigh increasingly strict restrictions on phone use overall. In July, Reuters reported that some deployed personnel in the Middle East could be ordered to surrender their phones amid concerns that mobile videos they were posting to the internet were helping Iran target American bases in the region.

A new study published Friday in AGU Advances "depicts the most advanced picture yet of how a rare but massive solar storm could affect some US industries and electric systems more than others," reports CNN. "During a 250-year solar storm, the East Coast would have widespread potential for grid failure." Researchers modeled what a Carrington Event — a 1-in-150-year geomagnetic storm or even rarer — could mean for the modern day. They estimate the US economy would lose about $1.5 billion to $2 billion per day from direct and indirect costs, as millions of people face power outages. The findings show the most vulnerable areas are the Northeast and the Northern Plains, especially locations at higher latitudes. No one knows when the next big storm will hit. While the most severe geomagnetic storms are labeled as once-in-a-century or rarer, these events don't follow a fixed schedule. "That timing only averages out on very long timescales," said Anna Kelbert, a geophysicist at the Harvard-Smithsonian Center for Astrophysics, who was not involved in the study but previously studied solar storm effects on power grids. "The event can occur at any time, as soon as a week from now, or centuries later...." [Shawn Dahl, service coordinator at the Space Weather Prediction Center operated by the National Oceanic and Atmospheric Administration in Boulder, Colorado], said the sun is now coming down from a period of heightened activity, which is also when some of the biggest storms to hit Earth have occurred in the past. "We still need a lot of work to be ready...." "We haven't really seen events like this size in the modern era, where we've had all of this high technology and we've had the power grid of this size," said Ed Oughton, researcher at George Mason University and lead author of the new study... Because the US grid's actual structure is proprietary for security reasons, the team used engineering models to create various network and transformer setups including the 10,464 substations and 16,256 transmission lines found across the country... The grid structure also contributes to higher risk in some areas. For instance, the eastern US is linked together in a single grid interconnection. A voltage issue in Maine, if not isolated early, could cascade through the grid to Washington, DC. The West works similarly, whereas the Texas interconnection operates mostly within the state... Power is restored over time depending on any alternative electrical paths that could bypass the substation or availabilities of spare transformers, for instance. "This nationwide analysis shows that we are currently ill-prepared to face a major magnetic storm, and that the societal impacts would be catastrophic," Kelbert said. "The study estimates power disruptions for 5.1 million people and 135,000 businesses," according to the article, and "The outages could last from hours to days to weeks depending on the damage and resources available to get back online, said Oughton."
