A newly disclosed flaw in the way OpenAI, Anthropic, and Google carried hidden AI reasoning between API calls let researchers recover internal reasoning and secrets from session logs, including API keys and passwords. The weakness affected encrypted reasoning objects used by the providers’ reasoning APIs, where a block created in one session could be replayed into another and, during testing, even handed to a weaker model in the same provider family to make it reveal the hidden content. The team behind the paper Stealing Reasoning Traces from Proprietary LLM APIs demonstrated four abuse paths: stealing proprietary reasoning for model distillation,…

The Office of the Comptroller of the Currency says it will keep pushing to revive de novo bank chartering, a campaign that has already opened a federal on-ramp for some of the largest companies in crypto. In a statement Tuesday, the regulator said reinvigorating new bank formation remains a priority and commended the Federal Deposit Insurance Corporation for its own recent efforts on the issue. “De novo chartering is a sign of a healthy banking system,” said Comptroller of the Currency Jonathan V. Gould, adding that the FDIC’s new process for reviewing deposit insurance applications aligns with the OCC’s work…

Imagine stepping into a machine that can make you feel like you’re flying a spacecraft, piloting a next generation air taxi, or landing on the Moon, all without leaving the ground. NASA’s Vertical Motion Simulator, the largest of its kind in the world, does exactly that. And now, with new upgrades, it’s more powerful and realistic than before. The Vertical Motion Simulator, located at NASA’s Ames Research Center in California’s Silicon Valley, has shaped the future of aviation and spaceflight since 1979. It allows pilots and researchers to experience realistic aircraft motion due to its ability to travel 60 feet…

Reservoirs have rebounded, but the fight over water isn’t over in Corpus Christi. The City Council has ordered a public referendum on a citizen-led petition that would sharply increase the price of water for industrial facilities during drought.  The proposal is expected to face a litany of legal challenges before November’s election.It would add millions of dollars in fees to the region’s largest water users, including ExxonMobil, Occidental Chemical and Valero, the next time reservoir levels are below 30 percent full, like they were for 29 months until early August. Community and environmental groups gathered nearly 13,000 signatures of registered…

Operations Development, which covers the development of methods and tools for installation and maintenance, will be…

Japan’s yen has slid back towards 160 to the dollar, despite last month’s extraordinary US-Japanese intervention. Traders are betting that its role as a cheap funding pipeline for global finance will continue. Earlier this month the Trump administration stepped in to help Tokyo stabilise its currency. “Japan’s been very good to us, with the exception, of course, of Pearl Harbor,” Donald Trump explained. More help is likely to be on its way.But this is less a rescue of the yen than an attempt by Scott Bessent, the US treasury secretary, to preserve a cash spigot that benefits the US. Japan’s ultra-cheap money has…

The day before the first total solar eclipse on the Spanish mainland in more than a century, Mar Carretero-Castrillo, a 28-year-old astrophysicist, climbed the hill in the tiny and remote northern Spanish village where she spent her childhood summers staring up at the starry night sky.Ms. Carretero-Castrillo had returned home from her job overseas for the big celestial event, she said, with the “beautiful idea” of gathering a small watch party on the same hill to quietly experience the eclipse with snacks, scientific discussions and educational games played with kitchen colanders. “But we have this fiesta,” she said, looking down…

In fact, one of the last true 32-bit-only CPUs was the Pentium 4 Northwood chip, which was available for purchase between 2000 and 2008. I can’t remember the last time I actually saw a 32-bit-only machine.Couple that with Microsoft ending support for Office 365 on 32-bit architecture this December, and it’s pretty simple…

Reco is tracking a sophisticated and innovative campaign targeting both Salesforce and ServiceNow via what appears to be a custom made multi-platform toolset. Researchers believe the primary targets include telecoms, banks and financial-services firms, enterprise-software vendors (including security and data-privacy companies), and public-sector portals. The campaign has been named ‘City-Forum’. It is directed at both Salesforce Aura and the newer LWR implementations, where it is the first observed in‑the‑wild exploitation of Salesforce’s UI‑API guest surface. Furthermore, attacks on Aura (necessarily included in a Salesforce campaign since Aura users still outnumber LWR users) are integrated with the LWR attacks in a…
