This paper introduces Aligned RAG Evaluation, a matched-query protocol showing that attack success rate (ASR) hides defense-induced failures in RAG knowledge-poisoning defenses, distinguishing prevented attacks from newly introduced target-positive answers on HotpotQA and Natural Questions.
Analysts warn the looming rocket launch capacity crisis is more severe than expected, as surging satellite and military launch demand outpaces supply, with Blue Origin's New Glenn ramp-up and US military launch needs as key wild cards.
The Pentagon's DIA released a full-resolution image of China's top-secret winged spaceplane, closely resembling the US X-37B, photographed in orbit by a Maxar/Vantor commercial satellite. The report details China's four spaceplane missions since 2020, including recent on-orbit satellite capture and release demonstrations.
文章强调 AI agent 的安全防护不能只依赖告警日志，必须验证检测结果是否真正转化为阻止执行的裁决。以 StackOne 开源的 Defender 为例，说明其 blockHighRisk 默认关闭、文本清理仅为尽力而为，建议开发者对已知恶意输入做端到端验证，确认应用层确实拦截了被标记的内容。
DIA's assessment reveals China's advancing counterspace capabilities, including ground-based lasers, robotic arms, and inspector satellites that make its secretive spaceplane unable to hide in low-Earth orbit, amid growing orbital weapon deployments by the US and Russia.
Dallas-based investment firm Disruptive announced a $10 billion flagship fund to back at least 10 late-stage companies with checks of up to $1 billion, targeting capital-intensive fields like AI and defense. The fund is the largest ever raised in Texas history and represents the firm's first blind-pool fund.
US Space Force leaders want a third heavy-lift spaceport operational by 2030 to ease pressure on Florida and California launch sites, but the Pentagon has yet to decide on a location or land acquisition plan.
OpenAI 的团队与 OpenCode 合作，帮助受攻击影响的 OpenAI API 用户恢复正常使用，并退还未消耗的额度；同时开放 Daybreak Blue 网络安全环境供防御使用。
该论文研究了医疗多智能体系统中的提示注入攻击，发现单个注入片段可使攻击成功率高达61%，并提出一种免训练的防御方法，通过将患者临床发现与临床判断分离验证，将MedQA上的攻击成功率降至4–7%且不损失正常准确率。
CSIS 分析探讨美国国防部如何重建并重塑弹药工业基础，指出 FY2027 预算中 PAC-3、THAAD 和战斧导弹采购量大幅增长，但仍需国会拨款、企业资本支出与实际合同才能实现目标。
论文提出 TRACER，一种通道感知的对抗训练方法，通过采样不同呈现通道并结合答案锚定、证据门控奖励来防御间接提示注入，在 GSM8K 上将 RAG 框架下的攻击成功率从 65.5% 降至 6.1%，同时保持较高的干净准确率。
Hooman Renzhad announced raising $80M to advance rare earth metal production in the U.S., noting the company is the only active American producer of materials like samarium, vital to defense, and is hiring across engineering and operations roles.
SpaceX has reportedly introduced speed restrictions on StarShield terminals used in Ukraine, disrupting drone command links and highlighting Kyiv's dependence on private satellite infrastructure for battlefield communications.
Block (Square, Cash App, Afterpay) is using OpenAI's Defense Factory and Daybreak model to automate security operations, cutting investigation times from weeks to hours and boosting triage throughput by 50%.
MIT Lincoln Laboratory hosted the National Security Commission on Emerging Biotechnology (NSCEB) for a national roadshow stop, convening stakeholders to discuss how Massachusetts' biotech ecosystem can strengthen U.S. biodefense capabilities amid Chinese competition.
The US military has officially ended the Defense Support Program, the long-running constellation of infrared satellites first launched in 1970 to detect Soviet ICBM launches and later used to monitor Iraqi Scud missiles, with the last operational satellites flying until 2007.
NASA is reaching out to former SR-71 Blackbird staffers to help restart the program and return to flight, as reported by Aviation Week.
SEAD 提出将工具使用智能体的攻击与防御统一为部分可观测状态控制问题，其中 DART 通过分解有害目标并利用工具执行反馈指导轨迹搜索来提升攻击成功率，SAGE 则通过只读查询在执行前检查状态来拦截有害操作，在在线攻防评估中将 DART 的可执行攻击成功率从 48.0% 降至 4.0%。
The article explains how the US lost its dominance in rare earth processing to China, leading to dependence and providing China with significant geopolitical leverage in technology and defense sectors.
A NATO-backed startup, Scaleout Systems, is using small AI models and federated learning to enable drones to autonomously identify and attack targets in battlefield settings, leveraging edge computing for real-time updates.
