Mitigating Taint-Style Vulnerabilities in MCP Servers Via Security-Aware Tool Descriptions

Large language models LLMs are increasingly deployed as autonomous agents that interact with external tools and services via the Model Context Protocol MCP, a standardized interface for dynamic tool invocation. While MCP simplifies integration, it also expands the attack surface and enables gener...

Mitigating Cyber Risk in the Age of Open-Weight LLMs: Policy Gaps and Technical Realities

Open-weight general-purpose AI GPAI models offer significant benefits but also introduce substantial cybersecurity risks, as demonstrated by the offensive capabilities of models like DeepSeek-R1 in evaluations such as MITRE's OCCULT. These publicly available models empower a wider range of actors...
