ASTRA: API Security Threat & Risk Atlas

ASTRA is a structured, community-driven threat matrix for API security, modeled after MITRE ATT&CK but built specifically for APIs. It provides a protocol-native knowledge base covering REST, GraphQL, gRPC, WebSocket, and SOAP across five tactic categories: Reconnaissance, Authentication Abuse, Authorization Failure, Exfiltration, and Impact. Version 1.0 includes 14 techniques such as BOLA, BFLA, JWT none algorithm bypass, GraphQL introspection leaks, excessive data exposure, and API DoS. Each technique includes a description, attack scenario, protocol applicability, composite severity score, a ready-to-use Sigma detection rule, a real-world breach mapping (e.g., Twitter 2022, Optus 2022, Peloton 2021), and remediation guidance. The project is open source under CC BY 4.0, accepts community contributions, and is designed for threat modeling, penetration testing, and SIEM integration.

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/

KEVIntel: Real-Time Intelligence on Exploited Vulnerabilities

KEVIntel is a dynamic platform providing up-to-date information on known exploited vulnerabilities (KEVs). It aggregates data from over 50 public sources, including CISA, and enriches each entry with metadata such as EPSS scores, online mentions, scanner inclusion, and exploitation status. The platform aims to serve as an early warning system, offering insights even before official publications. KEVIntel supports various formats like JSON, CSV, and RSS, facilitating integration into security operations. These entries include CVSS scores, exploit status, and links to proof-of-concept code, aiding organizations in prioritizing remediation efforts.   https://kevintel.com/
