Treasury’s Scott Bessent says no liability exemptions for AI labs

Treasury Secretary Scott Bessent urged Congress to reject AI labs' requested liability exemptions, arguing creator liability is the best safety guarantee.

Testifying before the House Financial Services Committee, Treasury Secretary Scott Bessent said the government should not grant frontier labs liability waivers, responding to Anthropic CEO Dario Amodei's slowdown essay. He cited Treasury's AI safety work since the release of Anthropic's Mythos model, whose cybersecurity risks prompted an April meeting, and coordination with banks and labs after the July Hugging Face cyberattack. Bessent also highlighted the Gold Eagle clearinghouse run with CISA and called for more US-built open-source models to counter China.

HYDRA: Quantifying Botnet Resource Thresholds for Efficient Link-Flooding Attacks on LEO Satellite Networks

HYDRA models link-flooding attacks on LEO satellite constellations as botnet minimization, matching prior disruption with 34% fewer bots and 23% less traffic.

HYDRA formulates link-flooding attack variants against LEO constellations such as Starlink and Kuiper as botnet minimization problems, quantifying the smallest bot subset and traffic allocation needed to disrupt communications between targeted geographic areas. Under matched stealth constraints it matches the ICARUS attack's disruption using 34% fewer bots and 23% less aggregate traffic, sustaining over 97% attack success as topology evolves. The framework also evaluates five mitigations, including routing diversification, ingress policing, distance-based constraints, source throttling, and botnet attrition.

Besxar is building an orbital semiconductor factory, one SpaceX rocket at a time

Besxar, founded by a former OpenAI staffer, raised ~$14M to prototype semiconductor manufacturing in orbit using SpaceX Falcon 9 booster flights.

Besxar, founded by former OpenAI staffer Ashley Pilipiszyn, raised almost $14 million, including a $9 million seed led by Dauntless Ventures and Overture VC, to build orbital semiconductor fabrication. Its first two "fabship" canisters flew on a July Starlink mission and returned wafer samples cleaner than comparable terrestrial wafers. The company plans to iterate over two years with a dozen Falcon 9 booster flights before flying larger fabs on Starship, targeting wafers for power-regulation chips used in data centers, robots, and electric vehicles.
