EchoLeak (CVE-2025-32711): The First Zero-Click Production LLM Exfiltration
A single crafted email could exfiltrate data from Microsoft 365 Copilot without a user click. We walk the attack chain, the patch, and the lessons for agent operators.
What Is Prompt Engineering? A Security Guide for LLM Applications
Prompt engineering is how you steer an LLM, and it is also where a lot of application security now lives. Here is how to write prompts that resist injection and leakage.
AI SBOMs and Model Cards: Building Transparency Into the AI Supply Chain
As AI models become critical software components, the need for AI-specific SBOMs and model cards grows urgent. How the industry is extending supply chain transparency to machine learning pipelines.
PyTorch CVE-2025-32434: weights_only=True No Longer Safe
A critical PyTorch RCE bypassed the safety property of torch.load(weights_only=True). We analyze the bug and explain why safetensors should now be the default.
