An anonymous reader quotes a report from TechCrunch: A group made up of dozens of cybersecurity experts, including several well-known veterans of the industry, published an open letter to the U.S. government asking it to lift the export control order on Anthropic's Fable and Mythos models. According to the open letter, "this action has taken the best models away from [cybersecurity] defenders" who now can't use the models to find vulnerabilities and make their software and products more secure. "To pull the best capabilities away from defenders without a good reason when our adversaries are rapidly advancing is dangerous," read the letter.

On Friday, the U.S. government ordered Anthropic to limit the export of Fable and Mythos, citing national security concerns, without explaining the specific reasons behind the order, according to Anthropic. In response, the company suspended access to the models to all users worldwide. As of this writing, the letter is signed by 76 cybersecurity experts, including Alex Stamos, former Facebook chief of security; Casey Ellis, the founder bug bounty platform Bugcrowd; Jon Callas, famed cryptographer and former Apple security design and architecture manager; Paul Vixie, computer scientist ; Dino Dai Zovi, the former head of applied security engineering at Block; Katie Moussouris, the founder of Luta Security; and Rachel Tobac, the CEO of the security awareness training firm SocialProof Security.

[...] Anthropic said that the White House export control order may have been based on a report that there was a method to bypass -- or jailbreak -- Fable to unlock its powerful Mythos-level capabilities. According to Katie Moussouris, one of the signatories of the open letter, the method was demonstrated by Amazon researchers in a paper that is not public but that she has reviewed. But Moussouris said in a blog post that the paper did not actually demonstrate a real jailbreak. Instead, she wrote, the researchers simply asked Fable to fix open source code with public and known vulnerabilities along with "deliberately planted vulnerabilities," after the model initially refused to "review the code for security issues."

"The behavior described in the paper cannot meaningfully be fixed, and any attempt would only weaken the model for defense," Moussouris wrote. "Defenders need to be able to ask AI to fix the bugs in a file, explain why the fix matters, and write tests that confirm the patch works. That is not a guardrail bypass. It is the most valuable thing an AI model can do for defensive security: executing the find, fix, and test loop defenders run every day." Moussouris' critique was echoed in the open letter, which also said that the group of experts believe the model capabilities in the Amazon paper "can be replicated" on OpenAI's GPT-5.5, on Anthropic's own publicly available Claude Opus 4.8 and Sonnet, "and even Chinese models like Kimi 2.7."

Moussouris told TechCrunch that "the bugs used to demonstrate the techniques in the paper can be found using the other models. The method in the paper is a guardrail bypass technique. Other models that lack the Fable guardrails often won't refuse the straightforward request to look for security bugs, so they don't need a bypass." The letter also asked for transparently and fairly enforced regulations created by "a democratic rule-making process" that are based on scientific research done by industry and academic experts, and "used only to the minimal extent necessary to ensure the safety of the American public."

• Fifa president sets gruelling itinerary across tournament

• World Cup to generate about 9m tons of carbon dioxide

Gianni Infantino is planning to attend two World Cup games each day where possible for the rest of the tournament despite the huge distances involved.

The Fifa president has access to a private jet provided by Qatar Airways as a value-in-kind element of its sponsorship deal with the world governing body, which will come in useful as Infantino journeys across the United States, Canada and Mexico.

I’ve met many hardcore, violent fans, but the hostage-negotiating, cocaine-smuggling, Marxist-Leninist Alessandro Casolari still stood out

I had heard the name Alessandro Casolari on and off for years. From 2016 onwards, when I was researching my book on Italy’s ultras – a cross between English football hooligans and Hells Angels – the nickname “Caso” kept coming up. In the late 80s and early 90s, he had led the ultras in Ferrara, whose football club is known as Spal.

A red-brick city in northern Italy between Bologna and Venice, Ferrara has always felt sidelined, languishing in a marshy land of fog and floods. I used to go there quite often, drawn by its festivals and famous writers and film directors. A few years ago, when I started writing another book, about the Po River, I hung out there again, but I never bumped into Caso.

Once a year, Dutch kids, parents and teachers take part in a walking festival, heading out for four nights in a single week to explore their neighbourhoods, exercise and make friends. It’s a tradition that seems to be genuinely transformative

I shouldn’t have been surprised that the rain didn’t stop the Dutch kids. All day it had been thunderstorming, and the forecast didn’t look so great for the evening. And yet at 5pm, hundreds of kids started arriving – many by bike – with their parents to Amsterdam’s Westerpark, a beloved city park that caters to a more residential area of the capital. Today, it functions as a starting point: volunteers coordinate registration, and groups of children gather, decked out in raincoats and eager to embark on either a 5km or a 10km excursion around the surrounding neighbourhoods.

It’s the second night of Avondvierdaagse (which literally means “four-day evening walk”) , organised by a group of neighbourhood volunteers. It’s not a race, but if children complete every night, they get medals, a bouquet of flowers and, if they’re lucky, a lot of sweets. It’s not just Amsterdam; across villages, towns and cities in the Netherlands, hundreds of thousands of Dutch people are doing the same: every year, kids spend four evenings in early summer exploring their neighbourhoods with their school friends and parents as part of the Week van de Avond4daagse. Some places had celebrated earlier; others were walking the following week. A variation of the tradition has even made its way to Suriname, one of the Dutch former colonies. There are also four-day cycling and swimming events. According to the Royal Dutch Walking Association (KWbN), which helps coordinate the events, half a million people take part every year, in 700 locations across the country, powered by tens of thousands of volunteers.

Exclusive: Commons motion calls for code of practice to be blocked amid concerns over impact on transgender people

A number of Labour MPs are increasingly doubtful that the guidance on how organisations should implement the supreme court ruling on sex as it applies in the Equality Act is workable in the real world, with some predicting it will unleash a wave of competing legal claims.

A total of 135 MPs, 69 of them from Labour, have signed a Commons motion calling for the code of practice drafted by the Equality and Human Rights Commission, approved last month, to be blocked, primarily because of worries about its impact on transgender people.

Bobby Robson employed a head of human performance for the World Cup and, despite wariness, the players got on board

The eve of Italia 90. Gazza’s tears, England’s heartache, and the cascading emotions of a World Cup that sang and ultimately stung still lie ahead. For now, the sports scientist tasked with acclimatising Bobby Robson’s side to the Italian summer is using cutting-edge technology to assess each player’s fitness: a BBC microcomputer, a dot-matrix printer, and a few clunky Polar heart-rate monitors.

Some in the England setup initially regard Prof John Brewer, the Football Association’s first head of human performance, with suspicion. But after monitoring the squad with a bleep test at Lilleshall before they fly to Italy, again when they arrive, and for a third time after a fortnight’s training in the hottest part of the day, Brewer can prove to the players they have adapted to the heat, and can play their familiar high-tempo game.

He built modern Greece from the ground up, but Ioannis Kapodistrias remains a controversial figure. A new biopic throws light on this overlooked titan of European history

On a hilltop in central Corfu, a marble bust carved in the classical style gazes skyward, lean, fine-featured and composed to the point of austerity. There is no uniform, no decorations, nor symbols of office, just a name cut into the base in Greek capitals: Ι Α ΚΑΠΟΔΙΣΤΡΙΑΣ. The bust stands alone in the gardens of Koukouritsa, once the family home of Ioannis Kapodistrias, the first governor of Greece. The villa is now the only museum in the country dedicated to the man who gave up one of the most powerful diplomatic positions in Europe to return to a country that was barely a country and try to build one.

Without Kapodistrias, there may have been no modern Greek state, and the map of Europe might look very different today. He spent years supplying material and moral support to the Greek revolutionaries; once independence was won from the Ottoman Empire, he negotiated directly with Britain, France and Russia over the new country’s borders and future, then set about building the institutions, its currency, courts, schools and civil service that the modern state still stands on. “He who murdered Kapodistrias murdered his homeland,” Swiss philhellene Jean-Gabriel Eynard wrote on hearing of the statesman’s assassination in 1831 at the hands of rebel leader allies turned enemies.

So-called ‘good behaviour’ legislation fiercely criticised by opposition politicians and rights groups

Sweden’s parliament has voted to escalate the country’s crackdown on immigrant rights, backing laws that allow authorities to revoke residency permits based on a vague criteria of bad behaviour and obliging most public sector workers to report anyone suspected of being undocumented.

The new legislation comes ahead of parliamentary elections in September, pitting the centre-right government, which currently depends on the support of the far-right Sweden Democrats to govern, against a far right that has said its intent is to create one of Europe’s most hostile environments for non-Europeans.

Works of Ali Smith, Kathleen Jamie and more to feature in celebration of literature’s interplay with other art forms, says director

This year’s Edinburgh book festival is expanding its slate of genre-busting musical events, including staging Japanese Noh theatre at one of the city’s oldest religious sites, Greyfriars Kirk.

Jenny Niven, the Edinburgh international book festival’s director, said such events broke away from the traditional formula of authors sitting in tents, and aimed to attract new audiences and celebrate literature’s interplay with other art forms.
