Maven-Hijack Exposes Hidden Risks in Java Dependency Resolution

The study introduces Maven-Hijack, a supply-chain attack that exploits how Apache Maven and the Java Virtual Machine resolve dependencies. By inserting a malicious class with the same fully qualified name as a trusted one earlier in the dependency chain, attackers can override legitimate functionality without altering project code or library names. Researchers demonstrated the attack by hijacking the Corona-Warn-App’s database logic. They assessed countermeasures such as sealed JARs, Java Modules, and Maven’s Enforcer plugin, concluding that Java Modules offer the strongest defense while the Enforcer plugin provides the most practical mitigation.

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/

NIST Updates Guidelines: Focus on Strong Passwords and MFA Over Frequent Rotation

 NIST has updated its guidelines, advising against mandatory password changes every 30-90 days unless a breach occurs. Frequent changes often lead to weak passwords, as users may make minimal adjustments. The focus has shifted to strong passwords and Multi-Factor Authentication (MFA) as more effective security measures. Despite this, automated password rotation remains crucial for securing sensitive accounts, especially for privileged users. It helps prevent unauthorized access, reduces exposure time, and ensures strong, unique passwords without burdening users. https://www.techradar.com/pro/navigating-nists-updated-password-rotation-guidelines
