Common OAuth Vulnerabilities and Best Practices

The article covers common vulnerabilities in OAuth2, emphasizing how misconfigurations and insufficient understanding of the protocol's complexities can lead to security flaws. It highlights different OAuth flows, including Implicit, Authorization Code, and Client Credentials Flows, along with attacks like token interception. The piece provides recommendations for secure implementations, including OAuth 2.1's updated practices and a comprehensive checklist for developers and testers.

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/
