elastic/cicd-abuse-detector: CI/CD Abuse Detection

This GitHub repository hosts a **prototype CI/CD abuse detector** from Elastic Security Labs. It provides drop-in CI templates that use an LLM (Claude) to detect suspicious changes to pipelines, workflows, and automation configurations – specifically targeting attacks where stolen credentials are used to modify workflows and harvest CI secrets. The detector works by filtering changed CI/CD files, generating per-file diffs, enriching them with regex-based prescreen labels, having an LLM analyze the diff for credential-harvesting threats, then alerting (Slack, issues, Elasticsearch) and optionally failing the PR based on severity thresholds. It includes reference templates for GitHub Actions, GitLab CI, and Azure DevOps. The repository is **not an officially supported Elastic product** – users are expected to fork and customize the templates, prompts, and schemas for their own environment. Documentation covers architecture, threat model, setup per platform, alerting, and testing.

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/
