GuardDog 3.0: Smarter Detection for Malicious Open-Source Packages

GuardDog 3.0 is a major update to Datadog's open-source supply chain security scanner for npm, PyPI, and other package ecosystems. The release replaces Semgrep with a YARA-based scanning engine for faster, more scalable static analysis, introduces a new risk scoring system that correlates multiple indicators into an overall maliciousness score, and adds built-in sandboxing using nono-py to safely analyze untrusted packages. The new architecture aims to improve detection accuracy while reducing false positives, making GuardDog more effective at identifying modern software supply chain threats without relying on LLMs or dynamic code execution.

Prompt Engineering Demands Rigorous Evaluation

In the blog post “Prompt Engineering Requires Evaluation” on the Shostack + Associates website, the author argues that treating prompts for large language models (LLMs) merely as creative artefacts is insufficient. Engineering prompts properly demands structured evaluation frameworks — what the AI community calls “evals” — to test which prompt versions work better, with which models, and under which conditions. The post highlights that simply assuming a prompt is “good enough” creates risks when LLMs are integrated into production systems (e.g., for threat modeling). It advocates for measuring prompt performance, variation effects, and tool-chain dependencies (model, context, ancillary materials).  Ultimately the message is: prompt engineering should borrow disciplined practices from software engineering (versioning, testing, benchmarking) rather than relying on informal experimentation.  https://shostack.org/blog/prompt-enignieering-requires-evaluation/
