  • Russia's VPN Crackdown Caused Bank Outages, Telegram Founder Says
    by EditorDavid on 06/04/2026 at 7:34 am

    Russia's "great crackdown" on VPNs — and a clampdown on Telegram's messaging platform — had an unintended side effect, reports Bloomberg. It "triggered the widespread banking outage seen across the country this week, Telegram's billionaire founder Pavel Durov said." "Telegram was banned in Russia, yet 65 million Russians still use it daily via VPNs," Durov said Saturday in a post on Telegram. "The government has spent years trying to ban VPNs too. Their blocking attempts just triggered a massive banking failure; cash briefly became the only payment method nationwide yesterday." Attempts on Friday to limit VPN use could have sparked the disruption affecting banking apps, The Bell and other Russian media reported, citing industry sources who weren't identified. The outage may have been caused by an overload in the filtering systems run by Russia's communications watchdog, according to the reports, with experts warning that major restrictions risk undermining network stability... Separately, payments for Apple Inc.'s app store and other services became unavailable in Russia from April 1, the US company said on its website, without saying why. Earlier, RBC newswire reported that the Digital Development Ministry had asked mobile operators to disable top-ups, which could help limit VPN use.... Durov, who's being investigated in Russia for allegedly aiding terrorist activity, compared the situation in his home country to Iran, where similar restrictions prompted widespread adoption of VPNs instead of the intended shift to state-backed messaging apps. "Welcome back to the Digital Resistance, my Russian brothers and sisters," said Durov, who has lived in Dubai and France in recent years. "The entire nation is now mobilized to bypass these absurd restrictions," he wrote, adding that Telegram would continue adapting to make its traffic harder to detect and block.

  • Artemis Astronauts Enter Moon's Gravitational Pull, Catch First Glimpses of Far Side
    by EditorDavid on 06/04/2026 at 4:41 am

    NASA's Artemis astronauts are now entering "the lunar sphere of influence," reports NBC News, "meaning the pull of the moon's gravity will become stronger than Earth's." Now as they begin their swing around the moon, the Artemis astronauts "are chasing after Apollo 13's maximum range from Earth," reports the Associated Press, hoping to beat its distance from Earth by more than 4,100 miles (6,600 kilometers). They'll begin their six-hour lunar flyby 14 hours from now (at 2:45 p.m. ET Monday). But in a space-to-earth interview Saturday with NBC News, the astronauts were already describing their first glimpses of the edge of the far side: [NASA astronaut Christina Koch realized] it looked different from what she was accustomed to on Earth. "The darker parts just aren't quite in the right place," she said. "And something about you senses that is not the moon that I'm used to seeing...." [Astronaut Reid] Wiseman called the flight a "magnificent accomplishment" and said the astronauts' ability to gaze at both Earth and the moon from their spacecraft has been "truly awe-inspiring." "The Earth is almost in full eclipse. The moon is almost in full daylight, and the only way you could get that view is to be halfway between the two entities," he said... And while the early photos of Earth and the moon that [Canadian astronaut Jeremy] Hansen and his colleagues have beamed back have been spectacular, the Canadian astronaut said they pale in comparison to the real deal outside their capsule's windows. "I know those photos are amazing," he said, "but let me assure you, it is another level of amazing up here." And their upcoming six-hour lunar flyby "promises views of the moon's far side that were too dark or too difficult to see by the 24 Apollo astronauts who preceded them," notes the Associated Press: A total solar eclipse also awaits them as the moon blocks the sun, exposing snippets of shimmering corona.... At closest approach, they will come within 4,070 miles (6,550 kilometers) of the moon. Because they launched on April 1, the rendezvous won't have as much of the far lunar side illuminated as other dates would have. But the crew still will be able make out "definite chunks of the far side that have never been seen" by humans, said NASA geologist Kelsey Young, including a good portion of Orientale Basin. They'll call down their observations as they photograph the gray, pockmarked scenes. There's a suite of professional-quality cameras on board, and each astronaut also has an iPhone for more informal, spur-of-the-minute picture-taking... Orion will be out of contact with Mission Control for nearly an hour when it's behind the moon. The same thing happened during the Apollo moonshots. NASA is relying on its Deep Space Network to communicate with the crew, but the giant antennas in California, Spain and Australia won't have a direct line of sight when Orion disappears behind the moon for approximately 40 minutes... Once Artemis II departs the lunar neighborhood, it will take four days to return home. The capsule will aim for a splashdown in the Pacific near San Diego on April 10, nine days after its Florida launch. During the flight back, the astronauts will link up via radio with the crew of the orbiting International Space Station. This is the first time that a moon crew has colleagues in space at the same time and NASA can't pass up the opportunity for a cosmic chitchat. Read more of this story at Slashdot.

  • Internet Bug Bounty Pauses Payouts, Citing 'Expanding Discovery' From AI-Assisted Research
    by EditorDavid on 06/04/2026 at 1:34 am

    The Internet Bug Bounty program "has been paused for new submissions," they announced last week. Running since 2012, the program is funded by "a number of leading software companies," reports InfoWorld, "and has awarded more than $1.5m to researchers who have reported bugs " Up to now, 80% of its payouts have been for discoveries of new flaws, and 20% to support remediation efforts. But as artificial intelligence makes it easier to find bugs, that balance needs to change, HackerOne said in a statement. "AI-assisted research is expanding vulnerability discovery across the ecosystem, increasing both coverage and speed. The balance between findings and remediation capacity in open source has substantively shifted," said HackerOne. Among the first programs to be affected is the Node.js project, a server-side JavaScript platform for web applications known for its extensive ecosystem. While the project team will continue to accept and triage bug reports through HackerOne, without funding from the Internet Bug Bounty program it will no longer pay out rewards, according to an announcement on its website... [J]ust last month, Google also put a halt to AI-generated submissions provided to its Open Source Software Vulnerability Reward Program. The Internet Bug Bounty stressed that "We have a responsibility to the community to ensure this program effectively accomplishes its ambitious dual purpose: discovery and remediation. Accordingly, we are pausing submissions while we consider the structure and incentives needed to further these goals..." "We remain committed to strengthening open source security. Working with project maintainers and researchers, we're actively evaluating solutions to better align incentives with open source ecosystem realities and ensure vulnerability discoveries translate into durable remediation outcomes."

  • Claude Code Leak Reveals a 'Stealth' Mode for GenAI Code Contributions - and a 'Frustration Words' Regex
    by EditorDavid on 05/04/2026 at 11:41 pm

    That leak of Claude Code's source code "revealed "all kinds of juicy details," writes PC World. The more than 500,000 lines of code included: - An 'undercover mode' for Claude that allows it to make 'stealth' contributions to public code bases - An 'always-on' agent for Claude Code - A Tamagotchi-style 'Buddy' for Claude "But one of the stranger bits discovered in the leak is that Claude Code is actively watching our chat messages for words and phrases — including f-bombs and other curses — that serve as signs of user frustration." Specifically, Claude Code includes a file called "userPromptKeywords.ts" with a simple pattern-matching tool called regex, which sweeps each and every message submitted to Claude for certain text matches. In this particular case, the regex pattern is watching for "wtf," "wth," "omfg," "dumbass," "horrible," "awful," "piece of — -" (insert your favorite four-letter word for that one), "f — you," "screw this," "this sucks," and several other colorful metaphors... While the Claude Code leak revealed the existence of the "frustration words" regex, it doesn't give any indication of why Claude Code is scouring messages for these words or what it's doing with them.

  • Hundreds of Theatres Show Apocalyptic-Yet-Optimistic New Movie, 'The AI Doc'
    by EditorDavid on 05/04/2026 at 10:39 pm

    Hundreds of theatres are now showing a new documentary called The AI Doc: Or How I Became An Apocaloptimist. Variety calls it "playful and heady,"edited "with a spirit of ADHD alertness." The New York Times suggests it "tries to cover so much that it ends up being more confusing than clarifying, but parts are fascinating." But the Los Angeles Times calls it an "aggravating soup of information and opinion that wants to move at the speed of machine thought." So while co-director Daniel Roher asks whether he should bring a child into a world with AI, "Perhaps more urgently, should Roher have made an AI doc that treats us like children?" First, he parades all the safety doomers, seeming to believe their warnings that an unfeeling superintelligence is upon us and we can't trust it. Then, sufficiently disturbed, he hauls in the AI cheerleaders, a suspiciously positive gang who can envision only medical miracles and grindless lives in which we're all full-time artists. Only then, after this simplistic setup where platitudes reign, do we get the section in which the subject is treated like the brave (and grave) new world it is: geopolitically fraught, economically tenuous and a playground for billionaires. Why couldn't the complexity have been the dialogue from the beginning, instead of the play-dumb cartoon "The AI Doc" feels like for so long? Maybe Roher believes this is what our increasingly gullible, truth-challenged citizenry needs from an explanatory doc: a flashy, kindhearted reminder that we're the change we need to be. Read more reactions here and here. Mashable warns the documentary's director "will ultimately craft a journey that feels like a panic attack in real time. In the end, you may not feel better about mankind's chances against the rise of AI. But you'll likely feel less helpless in the future before us all." They also point out that the film "shares some ways its audience can more actively be apart of the conversation, and provides a link to the film's website for engagement," where 6,948 people have now signed up for its newsletter. ("Demand a seat at the table," urges its signup button, under a warning that "Government and AI companies are designing our future without us. We need to reclaim our voice in shaping the future of AI...") Read more of this story at Slashdot.

  • Will 'AI-Assisted' Journalists Bring Errors and Retractions?
    by EditorDavid on 05/04/2026 at 9:22 pm

    Meet the "journalist" who "uploads press releases or analyst notes into AI tools and prompts them to spit out articles that he can edit and publish quickly," according to the Wall Street Journal. "AI-assisted stories accounted for nearly 20% of Fortune's web traffic in the second half of 2025." And most were written by 42-year-old Nick Lichtenberg, who has now written over 600 AI-assisted stories, producing "more stories in six months than any of his colleagues at Fortune delivered in a year." One Wednesday in February, he cranked out seven. "I'm a bit of a freak," Lichtenberg said... A story by Lichtenberg sometimes starts with a prompt entered into Perplexity or Google's NotebookLM, asking it to write something based on a headline he comes up with. He moves the AI tools' initial drafts into a content-management system and edits the stories before publishing them for Fortune's readers... A piece from earlier that morning about Josh D'Amaro being named Disney CEO took 10 minutes to get online, he said... Like other journalists, Lichtenberg vets his stories. He refers back to the original documents to confirm the information he's reporting is correct. He reaches out to companies for comment. But he admits his process isn't as thorough as that of magazine fact-checkers. While Lichtenberg started out saying his stories were co-authored with "Fortune Intelligence", he now typically signs his own name, according to the article, "because he feels the work is mostly his own." (Though his stories "sometimes" disclose generative AI was used as a research tool...) The article asks with he could be "a bellwether for where much of the media business is headed..." "Much of the content people now consume online is generated by artificial intelligence, with some 9% of newly published newspaper articles either partially or fully AI-generated, according to a 2025 study led by the University of Maryland. The number of AI-generated articles on the web surpassed human-written ones in late 2024, according to research and marketing agency Graphite." Some executives have made full-throated declarations about the threat posed by AI. New York Times publisher A.G. Sulzberger said AI "is almost certainly going to usher in an unprecedented torrent of crap," referencing deepfakes as an example. The NewsGuild of New York, the union representing Fortune employees and journalists at other media outlets, said the people are what makes journalism so powerful. "You simply can't replicate lived experiences, human judgment and expertise," said president Susan DeCarava. For Chris Quinn, the editor of local publications Cleveland.com and the Plain Dealer, AI tools have helped tame other torrents facing the industry. AI has allowed the outlets to cover counties in Ohio that otherwise might go ignored by scraping information from local websites and sending "tips" to reporters, he said. It has also edited stories and written first drafts so the newsrooms' journalists can focus on the calls, research and reporting needed for their stories.... Newsrooms from the New York Times to The Wall Street Journal are deploying AI in various ways to help reporters and editors work more efficiently.... Not all newsrooms disclose their use of AI, and in some cases have rolled out new tools that resulted in errors or PR gaffes. An October study from the European Broadcasting Union and the BBC, which relied on professional journalists to evaluate the news integrity of more than 3,000 AI responses, found that almost half of all AI responses had at least one significant issue. Last week the New York Times even issued a correction when a freelance book reviewer using an AI tool unknowingly included "language and details similar to those in a review of the same book published in The Guardian." But it was actually "the second time in a few days that the Times was called out for potential AI plagiarism," according to the American journalist writing The Handbasket newsletter. We must stem the idea being pushed by tech companies and their billionaire funders who've sunk too much into their products to admit defeat that the infiltration of AI into journalism is inevitable; because from my perch as an independent journalist, it simply is not... Some AI-loving journalists appear to believe that if they're clear enough with the AI program they're using, it will truly understand what they're seeking and not just do what it's made to do: steal shit... If you want to work with machines, get a job that requires it. There are a whole lot more of those than there are writing jobs, so free up space for people who actually want to do the work. You're not doing the world a favor by gifting it your human/AI hybrid. Journalism will not miss you if you leave... But meanwhile, USA Today recently tried hiring for a new position: AI-Assisted reporter. (The lucky reporter will "support the launch and scaling of AI-assisted local journalism in a major U.S. metro," working with tools including Copilot and Perplexity, pioneering possible future expansions and "AI-enabled newsroom operations that support and augment human-led journalism.") And Google is already sponsoring a "publishing innovation award"... Read more of this story at Slashdot.
