Copilot Word documents weaponized as self-replicating prompt injection vectors

Researcher Håkon Måløy has demonstrated a critical escalation in LLM attack surface: prompt injection vulnerabilities in Microsoft Word's Copilot integration can now self-replicate across documents. By embedding hidden instructions in source material, an attacker can trick Copilot into propagating malicious payloads into newly generated documents, creating a worm-like infection vector. This transforms prompt injection from a single-request exploit into a persistent, document-mediated attack that spreads through normal collaboration workflows. The finding exposes a fundamental tension in agentic AI systems: as models gain document manipulation capabilities, they become both more useful and more dangerous as infection vehicles.

World models gain mental state tracking for human behavior prediction

Researchers propose Mental World Modeling, a framework that extends traditional world models by treating agent beliefs, intentions, and social reasoning as first-class components rather than post-hoc interpretations. Current predictive systems track physical state evolution but miss the hidden mental variables that actually drive human behavior, leading to action predictions that fail despite accurate scene understanding. MWM couples physical and mental state tracking, enabling systems to simulate how actions reshape both what agents do and what they know or believe. This addresses a fundamental gap in embodied AI and multi-agent reasoning, with implications for robotics, dialogue systems, and human-AI interaction.

Separating specification from synthesis improves LLM code generation

A new research framework challenges how LLM agents approach program synthesis from scratch, where current methods fail on over 99% of tasks. The work separates behavioral specification elicitation as a distinct phase before code generation, drawing from classical software engineering practice. This addresses a critical gap in agent reasoning: existing end-to-end approaches conflate documentation parsing, behavioral exploration, and implementation, causing agents to misinterpret requirements early and propagate errors downstream. The insight matters for anyone building autonomous coding systems, as it suggests frontier models need structured exploration phases to ground their synthesis in actual system behavior rather than documentation alone.

Conformal prediction fails on minority classes, benchmark reveals fixes

Researchers expose a critical failure mode in standard conformal prediction methods when applied to imbalanced, high-stakes domains: minority-class coverage collapses to near-zero on real datasets, rendering uncertainty quantification unreliable precisely where it matters most. A large-scale benchmark across 15 imbalanced datasets and multiple calibration strategies reveals that class-conditional and cost-aware abstention mechanisms substantially recover coverage guarantees for rare but costly outcomes. This work directly addresses a production bottleneck in credit, fraud, and clinical AI systems where asymmetric error costs and severe class imbalance are endemic, offering practitioners a validated toolkit to deploy conformal methods safely in regulated environments.
