This paper introduces PaperGuard, a benchmark for evaluating and defending against adversarial attacks on multimodal AI peer review systems, covering both text and figure-based attacks across multiple scientific domains.

This paper introduces Zero-Shot Embedding Drift Detection (ZEDD), a lightweight framework that detects prompt injection attacks in LLMs by measuring semantic shifts in embedding space, achieving over 93% accuracy with less than 3% false positive rate across multiple architectures.

OpenAI launches Lockdown Mode, ChatGPT fully rolls out this mode to defend against prompt injection attacks and enhance security.

BYORn is a backdoor-robust fine-tuning framework for vision-language models that identifies and replaces poisoned responses with model-generated alternatives, improving robustness to backdoor attacks while maintaining clean-task performance.

Impulse Space, a company specializing in orbital maneuvering, raised $500 million in Series D funding to meet growing commercial and government demand, including from the US Space Force and NASA's Moon Base initiative.

Tenet Industries, backed by Y Combinator, is developing low-cost, mass-producible strike drones as an alternative to expensive defense systems built by traditional primes.

SpaceX has been awarded a $4 billion contract to build missile-tracking satellites as part of the 'Golden Dome' defense system, continuing its work on the Trump administration's defense initiative.

Introduces SCOUT, a framework that dynamically allocates prompt-injection detectors per request by predicting reliability and latency, improving safety and efficiency. Also presents SCOUT-450, a benchmark for complex agent-facing injections, showing a 46% reduction in attack-success rate and 40% latency reduction over a fixed GPT-4o judge.

This paper introduces multi-step trojan attacks against local LLM agents, where malicious prompts are embedded across multiple operations to bypass existing defenses. It proposes ClawTrojan benchmark and DASGuard defense to detect and mitigate such attacks.

YC is building a counter-drone ecosystem with startups like Perseus Defense, 9Mothers, surtrdefense, and Milliray, focusing on guided missiles, AI machine guns, sensor fusion, and drone detection.

Elon Musk claimed that US military suicide drones used the civilian Starlink service instead of the government-specific Starshield network, violating SpaceX's terms of service. The Pentagon denies any violation, and a dispute over pricing for Starshield access on kamikaze drones has emerged, with SpaceX requesting a higher fee.

The paper proposes Contextualized Defense Instructing (CDI), a new paradigm for privacy defense in LLM agents that uses a reinforcement learning-trained instructor model to generate step-specific, context-aware guidance, achieving a better balance between privacy preservation and helpfulness.

Niantic Spatial's Visual Positioning System (VPS) has been deemed 'Awardable' on the U.S. Department of War's Tradewinds Solutions Marketplace, enabling government agencies to procure the GPS-independent, deep learning-based localization technology for mission-critical environments.

This paper introduces open-book benign rewriting (OBBR) as a proactive defense against backdoor attacks on LLMs, showing it neutralizes harmful content by projecting to benign prompts, and improves safety by 51% over state-of-the-art defenses.

China has significantly increased production efficiency for J-20 stealth fighter components using a 'dark factory' that utilizes autonomous vehicles and AI-driven machinery with minimal human intervention.

Google disrupted a criminal group using AI to exploit a zero-day vulnerability in a company's digital defense, highlighting the growing threat of AI-driven cyberattacks.

OpenAI is launching Daybreak, an initiative designed to leverage AI for accelerating cyber defense and enabling continuous software security for partner companies.

Presents TurnGate, a turn-level monitor that detects hidden malicious intent in multi-turn dialogues by identifying the earliest turn where a response would enable harmful action, along with the Multi-Turn Intent Dataset (MTID) to support training and evaluation.

OpenAI has published a comprehensive Action Plan aimed at democratizing AI-powered cyber defense and coordinating with government and industry to address evolving cyber threats.

An opinion piece argues that the F-35 fighter jet is designed for a type of warfare that may no longer match modern military conflicts.
