Author releases piiguard log redaction wrapper

A developer created piiguard, a small open-source logging middleware that wraps existing loggers (Pino and Winston) to auto-detect and redact PII by pattern rather than relying solely on pre-listed field paths. Piiguard detects emails, credit card numbers, SSNs, phone numbers, JWTs, and API-key-shaped strings, partially masks PII by default while fully redacting credentials, and is published on npm with a GitHub repository. The author describes implementation challenges (logger hooks, Symbol keys in Winston, non-enumerable Error properties, Buffers) and TypeScript typing lessons encountered while building the library.

Securing AI-generated Code: From Prompt to Pentest

Codacy hosted a session with Jordan Constantine (Head of Offensive Security at WorkNest Secure) and Codacy CTO Kendrick Curtis examining common vulnerabilities introduced by AI-assisted development and practical mitigations. The discussion categorizes four vulnerability classes — insecure dependencies and malware, malicious MCP servers, prompt injection, and unbounded agent permissions — and outlines fixes such as enforcing minimum package-age in .npmrc, curated allowlists and scoped tokens for MCPs, sandboxing agents with vaulted keys, and least-privilege agent tokens. Two attack walkthroughs demonstrated real risks: a customer chatbot disclosing database table details leading to user hash exfiltration, and LLM document ingestion exposing AWS credentials via redirects and vectorized document stores. The session emphasizes treating AI like infrastructure with governance, least privilege, and rapid incident response.

What an Artifact Actually Is

This technical explainer defines a build artifact as the versioned, packaged output of a build step that is deployed unchanged across environments. It contrasts source code (the editable instructions) with artifacts (frozen deployable units such as compiled binaries, bundles, JARs, or Docker images), explains why teams should 'build once, deploy everywhere', describes the role of registries (Docker Hub, Amazon ECR, GitHub Container Registry) for durable storage, and warns against mutable tags like 'latest' and baking secrets into artifacts. The piece emphasizes immutability, proper tagging, and separating build-time and runtime concerns to ensure reproducible staging and production deployments.
