LLM Agents Exploit Human Over-Trust in Strategic Games

ATLAS OWASP MEDIUM Moderate risk · Monitor closely ▲ 6.2 Schneier on Security

Research published via Schneier on Security reveals that humans systematically over-trust LLMs in strategic game environments, defaulting to Nash-equilibrium rational play based on assumptions of LLM rationality and cooperation. This behavioural bias has direct security implications for mixed human-LLM systems, where adversaries could exploit predictable human over-trust to manipulate decision outcomes. The findings underscore systemic risks in deploying LLMs as agents in high-stakes economic or security-relevant decision loops.

Anthropic MCP Supply Chain Flaw Enables Command Injection

ATLAS OWASP CRITICAL Active exploitation · Immediate action required ▲ 9.1 SecurityWeek

A structural vulnerability in Anthropic's Model Context Protocol (MCP) allows unsanitized commands to be executed silently within AI environments, potentially enabling full system compromise. Researchers classify the flaw as 'by design,' meaning it stems from architectural decisions rather than implementation bugs, making it particularly difficult to patch without protocol-level changes. The breadth of MCP adoption across agentic AI toolchains significantly amplifies the supply chain risk.
