Anthropic's Claude Cracks Two Hardened Cryptographic Schemes

Claude Mythos Preview broke a post-quantum signature scheme and sped up an AES attack 200-800x, working largely autonomously.

Anthropic said its Claude Mythos Preview model, working with researchers and largely autonomously under occasional human guidance, found new weaknesses in two cryptographic systems: HAWK, a digital signature scheme designed to resist attacks from quantum computers, and a reduced version of AES (Advanced Encryption Standard), the widely used symmetric cipher. In 60 hours, Mythos Preview found a previously unknown attack that cut HAWK's key strength in half, despite the scheme surviving two years of expert review. On the AES variant, it sped up an existing attack by 200 to 800 times.

Anthropic worked with academics at ETH Zurich, Tel Aviv University and the University of Haifa to build a companion benchmark, CryptanalysisBench, for studying LLMs' cryptanalysis abilities, and disclosed the findings in advance to the algorithms' authors and to US government and industry partners. The company cautioned the results don't threaten current systems - HAWK isn't deployed anywhere yet, and the AES attack targeted a weakened version, not the full cipher - but said they show frontier models can now do "expert-level cryptography research," with defensive applications for testing the algorithms that secure everyday online activity. Each result cost roughly $100,000 in API usage.

xAI Reveals Grok 4.6 and 4.7 Release Timeline, Expands to Copilot

Grok 4.6 (1.5T params) arrives around Aug. 7, with a bigger Grok 4.7 to follow, as Grok also debuts inside Microsoft Copilot.

Elon Musk said xAI's Grok 4.6, a 1.5-trillion-parameter model with "significantly improved" supervised fine-tuning and reinforcement learning, is on track to release around August 7. A larger 2.1-trillion-parameter Grok 4.7 will follow a few weeks later; Musk said it will be "better than 4.6 in every way," except slightly slower to serve.

Musk also confirmed Grok is now available inside Microsoft Copilot, giving xAI's models a new distribution channel beyond X's consumer apps. Separately, Grok 4.5 reportedly took the top spot on the new HighWalk benchmark, which measures how well AI agents update technical specifications - a category increasingly relevant to agentic coding tools.


Apple Hits $5 Trillion Market Cap as Tim Cook Hands Reins to Ternus

Hardware engineering chief John Ternus takes over as CEO September 1, ending Cook's 15-year run atop the company.

Apple's market capitalization reached $5 trillion this week, according to reports, as Tim Cook and his designated successor John Ternus appeared together publicly for the first time since the succession was announced - at the Season 4 premiere of Apple TV+'s "Ted Lasso" in Los Angeles on July 27. Ternus, who has led Apple's hardware engineering for 25 years, becomes CEO on September 1.

At the event, Ternus praised the streaming service's momentum, while Cook emphasized quality over quantity and openness to partnerships like Apple TV+'s custom F1 movie coverage. The low-key handover caps a long-planned transition as Apple's stock has been outperforming the Nasdaq by its widest margin in 20 years, with shares near an all-time high.


Grocery Prices See Biggest Jump in a Half-Century

Food-at-home costs are up 33% since 2019, per federal data, even as wage gains lag behind at checkout.

US grocery prices have climbed 33% since 2019 through June 2026, the largest increase in decades, according to Bureau of Labor Statistics data cited by the Associated Press and X News. Median weekly earnings rose 38% over the same period, but middle-income households now spend a larger share of after-tax income on food than before the pandemic, and shoppers are increasingly couponing, comparison shopping and cutting back on favorite items.

Monthly price increases have slowed to 2.7%, but the lasting effect of pandemic-era supply disruptions and elevated demand means prices aren't reverting. The trend has become a political flashpoint, with views split along party lines over the causes.


New: Japan Earthquake Toll Rises as Buildings Collapse on Kyushu

Deaths and collapses at a shopping center and factory chimney go beyond the tsunami advisory reported a day earlier.

New: A 7.1-magnitude earthquake that struck Japan's southern island of Kyushu on Tuesday has left several people dead and dozens more injured or missing, officials said, after part of a shopping center and a large chimney at a paper factory collapsed. The scale of damage marks an escalation from initial reports, which had focused on a tsunami advisory issued for the Kumamoto region.

Japan's Meteorological Agency had issued the advisory as the quake hit; authorities have not yet detailed the full scope of casualties or infrastructure damage beyond the two collapses reported so far.

Anthropic and OpenAI Both Back Calls to Pace Frontier AI Development

Anthropic's CEO and co-founders signed a petition as OpenAI says the world may eventually need to slow AI acceleration.

Anthropic said its CEO, several co-founders and senior staff signed a petition calling for tools to "deliberately pace the frontier of AI development," pointing to its own research on risks from recursive self-improvement. OpenAI separately posted that "at some point in the future, AI acceleration for frontier model development may be so high that the world will need to pace the rate of AI advancement" - a notable point of alignment between the two rival labs. It follows Anthropic CEO Dario Amodei's comments this week distancing the company from calls for an open-weight AI ban while still pushing for chip controls and safety audits.


OpenAI Quietly Open-Sources Codex Security CLI

The tool scans repositories, tracks findings across runs, and can be wired into CI/CD pipelines.

OpenAI released an open-source Codex Security CLI without an initial announcement - Hacker News surfaced it before the company could publicize it. The early-release tool lets developers scan repositories for vulnerabilities, verify fixes, track findings across multiple runs, and add automated security checks to CI/CD pipelines.

Apple Preps Smart-Home Hub and Refreshed Siri Hardware

New Apple TV and HomePod mini land this fall, with a screen-equipped smart home hub expected by early 2027.

Apple plans to refresh its Apple TV 4K and HomePod mini with faster chips this fall to support enhanced Siri features, alongside a possible new Siri Remote, according to reports. A bigger move follows: a smart home hub with a 7-inch screen, a HomePod speaker, and a custom operating system for FaceTime, HomeKit control and security monitoring, expected between October 2026 and early 2027. The devices tie into Siri's overhaul arriving with iOS 27 this September, as Apple pushes for tighter AI-hardware integration after trailing Amazon and Google in the category for years.

New: Starship Survives Splashdown Intact, Still Floating in Indian Ocean

SpaceX dispatched a recovery ship after Flight 13's landing was precise enough to have been caught by the tower arms.

New: Two days after Starship's Flight 13, the vehicle remains afloat in the Indian Ocean, and SpaceX has dispatched a recovery ship to retrieve it, Elon Musk said. Musk noted that the ship's landing burn and splashdown were precise enough that it would have been caught by the launch tower's chopstick arms had it attempted a tower landing. SpaceX's recovery team has been gathering imagery of the still-floating vehicle in the meantime.


Falcon 9 Set for Playful-Patch Spy Satellite Launch Thursday

The NROL-95 mission for the NRO and Space Force features a ferret mascot patch reading 'We Are the Champions.'

SpaceX stacked a Falcon 9 vertically at Cape Canaveral's Space Launch Complex 40 ahead of the NROL-95 mission for the National Reconnaissance Office and US Space Force, set to launch at 3:09 a.m. ET on July 30. The mission's patch features a ferret mascot circled by "NROL-95" and "We Are the Champions," continuing the NRO's tradition of quirky mission patches. It's the fourth NRO launch of 2026, with the booster aiming for its seventh landing at Landing Zone 2.

Townhome Project Breaks Ground This Fall on Long-Vacant Covil Avenue Site

Frying Pan Ventures' 65-unit Covil Village replaces a shuttered assisted-living facility that sat empty for over a decade.

Construction on Covil Village, a 65-unit townhome community, is set to begin in early September on a 5.4-acre site at 202, 310 and 314 Covil Ave., according to the Greater Wilmington Business Journal. The property once housed Port South Village, an assisted-living facility that closed in 2013. Developers Andy Mitwol and Clayton Williams of Frying Pan Ventures LLC spent about two years tracking down the property's owners - the land had passed through multiple estates and a family trust - before getting it under contract within six months.
