Anthropic's Mythos Helped Build a Working macOS Exploit in Five Days

1 month 4 weeks ago
"The vulnerability is simple in practice," writes Tom's Hardware: "run a command as a standard user and gain root (administrator) access to the machine." And it was Mythos Preview that helped the security researchers at Palo Alto-based Calif bypass a five-year Apple security effort in just five days. The blog 9to5Mac reports: Last year, Apple introduced Memory Integrity Enforcement (MIE), a hardware-assisted memory safety system designed to make memory corruption exploits much harder to execute... [The researchers note it's built into Apple all models of the iPhone 17 and iPhone Air, and some MacBooks] They explain they have a 55-page technical report on the hack, but they won't release it until Apple ships a fix for the exploit. But they do note in broad terms that Anthropic's Mythos Preview model helped them identify the bugs and assisted them throughout the entire collaborative exploit development process. "Mythos Preview is powerful: once it has learned how to attack a class of problems, it generalizes to nearly any problem in that class. Mythos discovered the bugs quickly because they belong to known bug classes. But MIE is a new best-in-class mitigation, so autonomously bypassing it can be tricky. This is where human expertise comes in. Part of our motivation was to test what's possible when the best models are paired with experts. Landing a kernel memory corruption exploit against the best protections in a week is noteworthy, and says something strong about this pairing...." [I]n a time when even small teams, with the help of AI, can make discoveries such as this one, "we're about to learn how the best mitigation technology on Earth holds up during the first AI bugmageddon."

The Search for the Next 'James Bond' Actor Has Begun

1 month 4 weeks ago
Variety reports: Amazon MGM Studios started auditioning actors for the part of 007 in the past few weeks, Variety has learned... The next James Bond film will be directed by Denis Villeneuve, the filmmaker behind the "Dune" franchise, "Arrival" and "Sicario." Amy Pascal of the "Spider-Man" films and David Heyman of the "Harry Potter" series will produce the picture, which will feature a script from "Peaky Blinders" creator Steven Knight. Tanya Lapointe ("Dune") is executive producing the film. The BBC notes it's been five full years since the release of the last Bond film No Time To Die, and 15 months "since Amazon MGM Studios took control of the Bond franchise." But they also offer this list of "the current bookmakers' favourites" for who will become the seventh actor to play the gadget-loving super spy in the franchise's 64-year history: Callum Turner — the 36-year-old actor is the current bookies' frontrunner. He has been in the Fantastic Beasts franchise, was nominated for a Bafta for TV drama The Capture, and starred in Apple TV's Masters of the Air... Jacob Elordi — the Australian actor, 28, made his name in TV's Euphoria and cult hit film Saltburn, and was nominated for an Oscar this year for playing the monster in Frankenstein. The Rest Is Entertainment host Marina Hyde recently said she'd heard from a number of well-placed sources that he's now "in pole position" to be Bond. Harris Dickinson — the 29-year-old is playing John Lennon in the forthcoming major Beatles biopics, and has previously appeared in Maleficent, The King's Man, Where the Crawdads Sing and Babygirl, and received a Bafta TV Award nomination for A Murder at the End of the World. Henry Cavill — the Superman, The Witcher and Mission: Impossible actor is a fan favourite and was widely regarded to have been the runner-up when Craig landed the part. But at 43, is he now too old to start a lengthy stint as 007? Aaron Taylor-Johnson — the Bafta-nominated 35-year-old, known for films like Kick-Ass, Kraven the Hunter and 28 Years Later, is a perennial contender, and would fit the bill. Theo James — the suitably suave star, 41, made his name in the Divergent films and has since built his reputation in The Time Traveler's Wife, The White Lotus and The Gentlemen. ...Or producers could well go for one of the many other names who have been touted for the role, or an unexpected choice.
