How a Seemingly Harmless Image Can Jailbreak Vision-Language AI Models

✇Slashdot

Slashdot reader BrianFagioli writes: Florida International University researchers have developed a technique called JaiLIP (Jailbreaking with Loss-guided Image Perturbation) that uses subtle image modifications to bypass AI safety guardrails. Unlike traditional jailbreaks that rely on carefully crafted prompts, the attack works through images that appear normal to human viewers. The researchers tested the technique against BLIP-2, a multimodal AI model, and found that manipulated images significantly increased the likelihood of harmful responses. According to the study, the approach outperformed previous image-based jailbreak methods and nearly doubled the number of unsafe outputs generated during testing. The findings highlight a potential security risk for businesses deploying AI systems that process both images and text. While most discussions about AI safety focus on prompts, the research suggests that seemingly harmless images may also serve as an attack vector.

France's Heat This Week Was Worse Than a Dire Scenario Imagined For 2050

There's a deadly, record-breaking heat wave spreading east across Europe, reports the Washington Post — and it's even worse than a dire earlier forecast: The forecast was recorded in 2014 as part of a campaign coordinated by the World Meteorological Organization (WMO) that invited about 60 presenters worldwide to imagine a weather report from the year 2050. In one clip, Ãvelyne Dhéliat from French television network TF1 presented a hypothetical scenario of high temperatures 36 years into the future — during a heat wave in a warmer climate in 2050... One of the maps that Dhéliat shared was lit up in shades of orange, filled with temperature predictions of 40 degrees Celsius (104 degrees Fahrenheit), reaching as high as 43 degrees Celsius (109.4 degrees Fahrenheit). But it turns out, it didn't take 36 years for those imagined temperatures to be reached — and even exceeded. The heat on Wednesday alone, when the temperature soared as high as 112.3 degrees Fahrenheit (44.3 degrees Celsius), exceeded the 2050 projections in 19 out of 34 locations across mainland France — far sooner than some may have expected. Some places surpassed those hypothetical future temperatures by more than 20 degrees Fahrenheit. It's part of a dramatic shift in heat wave frequency across the country. Half of the heat waves observed since 1947 have occurred since 2010. "By 2100, heat waves could last up to two months continuously," the country's weather agency, Météo-France, said this week. It was hotter in France on Wednesday than in Las Vegas and Phoenix and just two degrees Fahrenheit shy of what was observed in Death Valley, California. An estimated less than one percent of the planet was hotter than France's hottest place... [T]he heat dome, which will linger into early next week, is only part of the story. This type of extreme heat is becoming more common as the planet warms, especially in Europe. Climate scientist Robert Rohde said in a post explaining the heat wave's causes that France and Western Europe should expect many more heat waves like this over the coming decades. "This isn't a fluke, but simply part of the new normal," he said. Thanks to Slashdot reader fjo3 for sharing the news.

Max Planck Slapped With Two Paper Retractions By Suspected Rogue Algorithm

Max Planck won 1918's Nobel Prize for physics. Yet two of his papers were retracted — a move now being criticized by Yves Gingras, a historian of physics at the University of Quebec and Mahdi Khelfaoui, a fellow historian of science at UQ Trois-Rivières. Science reports: The papers, both quietly retracted in 2011, originally appeared in the early 1940s in Naturwissenschaften, a German journal now owned by publishing giant Springer Nature. After some sleuthing, Khelfaoui determined one of the Planck pieces, a philosophical essay from 1942 titled "Sinn und Grenzen der exakten Wissenschaft" ("Meaning and Limits of Exact Science"), about how to achieve certainty in scientific knowledge, had also appeared in two other journals and been reprinted twice in books. Repackaging the same work multiple times is considered "self-plagiarism" and frowned upon today — the practice produces copyright conflicts and inflates scholars' publication records. The Naturwissenschaften site gives "copyright violation" as the reason for the retraction. Yet publishing identical material in multiple journals was widespread before the internet. "Science was more fragmented" then, Khelfaoui says. "You wanted different audiences ... to have access to your work." The practice was especially common for luminaries like Planck. Albert Einstein did the same (but escaped retractions). Springer Nature's "anachronistic" application of modern standards to a 1942 paper "distort[s] the historical record," Gingras and Khelfaoui argue in a preprint posted last month on arXiv. Any concerns about copyright violations are largely moot anyway: Because Planck died in 1947, his works are in the public domain in most countries. Gingras was especially incensed that Springer Nature deviated from the normal practice of merely slapping the word RETRACTED across the digital version of the paper while still allowing scholars to read the text. Instead, the publisher posted a blank white page with the cryptic phrase, "This article has been withdrawn due to article violation." Springer Nature is nevertheless still selling the empty PDF for $39.95. Suzanne Scarlata, a chemist and biochemist at the Worcester Polytechnic Institute and editor-in-chief of The Science of Nature, as Naturwissenschaften is now known, had not heard about the retractions before being contacted for this story... Scarlata suspects Springer Nature's internal policing software removed the paper and posted the retraction notice unilaterally, without human supervision: "I think it just happened with their algorithm," she says. "It's a mistake they should probably rectify." A second Planck paper was apparently removed because its response to a 1940 paper had used an identical title. Thanks to our long-time Slashdot reader He Who Has No Name for sharing the article.

Scroll Burned in 79 AD Volcanic Eruption Finally Deciphered Using AI

When Mt. Vesuvius erupted in 79 A.D., it buried hundreds of papyrus scrolls. They were rediscovered in the mid-1700s, remembers Smithsonian magazine, "the only surviving collection of its kind from the Greco-Roman world..." "But when scholars tried to unroll them, the carbonized manuscripts crumbled to dust." Every generation that followed faced the same dilemma: They could wait for technology to advance, abandoning hope of reading the ancient texts in their own lifetime. Or they could try to open the scrolls themselves — and risk destroying them. In recent years, researchers have settled on a third option. Using advanced imaging and artificial intelligence, they're deciphering the scrolls without needing to unroll them at all. The Vesuvius Challenge has accelerated the process by turning it into a public competition, complete with cash prizes. In 2023, a student won $40,000 for deciphering a single word — "purple" — from an unopened scroll. Later, contestants would identify 2,000 Greek characters from one scroll ($700,000) and the title of another ($60,000). Now, for the very first time, researchers have recovered all surviving text from a single scroll. The nearly five-foot-long segment includes roughly 20 columns of ancient Greek philosophy, accessible for the first time in nearly 2,000 years. "The tech actually does look like magic, but it's not," Brent Seales, a computer scientist at the University of Kentucky, said at a press conference. (The article points out that Seales partnered with two Silicon Valley investors in 2023 to launch the Vesuvius Challenge, and is now hailing "the restoration of lost voices from the ancient world." Seales has been working on virtually unwrapping the scrolls since the early 2000s. The process involved imaging the bundles of papyrus using technology similar to CT scanners, isolating thin layers and then stitching them together.... "We've developed a systematic and a repeatable approach," Seales told the audience. "Now it's only a matter of time until we read all of the scrolls."

California Sheriff Says Their Drone Disarmed a Suspect, Shares Video on Instagram

The Los Angeles Police Department says about 1,500 police agencies across America have drone programs, reports SFGate, and 58 of those drone-using police agencies are in California. The Sacramento County sheriff's office recently posted drone footage on Instagram set to theme from "Mission: Impossible," claiming "a nationwide first" where their drone successfully disarmed a felon "seen earlier with a firearm" (though now not moving, but holding a knife while lying face down in a garage). In the video the "not responding" suspect continues not moving as the drone dangles a magnet which catches on the knife. The drone then pulls multiple times until it comes out of the unmoving suspect's hand. The sheriff's office says their footage shows their drone "disarm an armed suspect, helping bring the incident to a safe resolution," in their post on Instagram, "rather than rush into a potentially deadly encounter..." Was he pretending to be dead or simply lying in wait for deputies to approach...? It's also worth noting that our drones are labeled as "military equipment" (even though anyone can purchase them at their local Walmart), but are really just another piece of technology helping deputies resolve dangerous situations safely. Their use protects both law enforcement personnel and suspects. SFGate offers more reports from around California: In Yucaipa, officials launched a Drone as First Responder (DFR) pilot program on May 28, the San Bernardino County Sheriff's Department announced this month. According to the release, drones have already been used to respond to over 100 calls for service, arriving before deputies for 71% of them. "The drones also contributed to 12 arrests, assisted in locating persons of interest on 37 occasions, and provided aerial overwatch during 44 incidents," it continues, though details on how they assisted the police are unclear. The drones, manufactured by Skydio, were also used to locate a young person experiencing a mental health crisis and another person launching illegal fireworks.

FSF 'LibreLocal' Organized From Prison by Iranian Man Jailed for 'Cyber-Crimes' After Promoting Free Software

✇Slashdot
Par : EditorDavid
27 juin 2026 à 16:34
Thursday the Free Software Foundation blogged about this year's 47 'LibreLocal 2026' meetups, highlighting 10 that took place in Australia, Mexico, the United States, New Zealand, Cameroon, Switzerland, Spain, Argentina, China, and Iran. "Far from each other in many parts of the world, they came together around one unifying belief: free software." We envisioned LibreLocal as a collage of in-person community meetups that would bring people together to swap ideas, learn from each other, and celebrate free software. When we asked the free software community to organize LibreLocals last year, the response was very inspirational: 29 different meetups were hosted. After we made the global call this year, we were greeted with an even more enthusiastic response... Organizers hosted LibreLocals in cafes, bars, restaurants, libraries, universities, a computer repair shop, and even as part of a field trip to the System Source Museum, a museum dedicated to the history of computing in Hunt Valley, Maryland, USA. We also learned that a LibreLocal was organized inside Vakil Abad Prison in Mashhad, Iran by a free software supporter. Originally planned to be held in Shiraz, we were informed of this change in location on the LibreLocal wiki page set up for listing all LibreLocals. The updated entry, by another free software supporter in Iran, reads: "This year, one of our dedicated activists organized a LibrePlanet event from within prison in Iran. Currently serving a sentence for "cyber-crimes" related to his promotion of free software, he continues to introduce the principles of software freedom to his fellow inmates. We have placed this banner to honor his resilience and the community of individuals in prison who continue to stand for technological freedom. His identity will be revealed when it is safe to do so." Advocating for user freedom should never result in a prison sentence. We especially admire and respect the bravery and strength of those who fight for software freedom in the most dangerous and oppressive of environments. 50 people attended the LibreLocal meetup in Switzerland, according to one of the organizers, "forging connections between several local free software stakeholders and strengthening their cohesion." But the FSF's blog post stresses these are "ten stories among many more of free software supporters from across the globe... We also thank you our donors and associate members for the support that makes such meetups possible." The GNU Press Shop is now open through July 19 for their biannual fundraiser, offering a variety of freedom-respecting novelties including an FSF-branded antisurveillance webcam guard and both technical and philosophical books, like Richard Stallman's Free as in Freedom (which allegedly has turned up in Anthropic's training data). Other items include a slick new FSF logo sticker, a brass and zinc GNU "emblem" pin with real gold plating, and a cheeky sticker reminding everyone that "There is no cloud." And there's even a plush GNU toy.

Bitcoin Drops Again. Skeptical Investment Strategist Calls It 'Useless'

Friday Bitcoin closed at just $59,948 — dropping 19% just for June and more than 50% lower than its record high in October of $124,310. To commemorate the occasion CNBC interviewed long-time bitcoin skeptic Jeremy Grantham, reporting that the 87-year-old cofounder/chief investment strategist of the massive asset-management firm GMO is "predicting it will gradually fade into irrelevance over decades." [The] longtime market commentator known for his calls on asset bubbles said bitcoin is a "useless, speculative" asset without intrinsic value, speaking on CNBC's "Squawk Box" Friday. He also said bitcoin hasn't outperformed during a bull market and questioned its practical use. "[Over] years and years, decades and decades, it will dwindle away, I suspect — not with a bang, but a whimper," he said. "It's not a stable form of value — it just halved ... for no particular reason in a strong economy, so you can't depend on it in that way." He added that gold has still delivered solid gains over the same period, even after pulling back from its highs. Bitcoin not only hasn't proved itself as a useful asset to speculate on, it doesn't provide any real world utility either, Grantham argued. "People don't use it to make serious trades, they don't use it to buy their dinner and pay at the supermarket. ... What it does is allows crooks to move money around," he said. Bitcoin has become notorious over the years for its dramatic bear market crashes, which has taken it down at least 70% from its peak in every cycle. The article adds that "many investors believe the current price slump could drag on for several more months."

US Government Allows Anthropic Limited Release of 'Mythos' AI Model, Saying 'Appropriate Safeguards are in Place"

"The US government has allowed Anthropic to release its powerful Mythos AI model to select companies and organizations," reports CNN, "revising license requirements after ordering an export block earlier this month in the wake of national security fears." Since the export ban earlier in June, "Anthropic has worked with the US government to address risks associated with the Covered Models," Commerce Secretary Howard Lutnick wrote to the company in a letter dated Friday. In light of progress in that work, Lutnick wrote, "I have determined that appropriate safeguards are in place to permit certain trusted partners to access the Claude Mythos 5 Model." The letter does not include permission for Anthropic to release Fable, a less powerful version of Mythos. "We received notice from the US government that Mythos 5, our strongest cybersecurity model, can be redeployed to a small group of cyber defenders and infrastructure providers," Anthropic said in a statement... Conversations between Anthropic and the government are expected to continue into the weekend, with an eye to restoring access to Fable, as well, a source familiar with the discussions told CNN.
