EDRSilencer Exploited by Threat Actors to Evade Detection and Disable Security Alerts

 EDRSilencer, a tool traditionally used in red-team operations, is now being exploited by malicious actors to bypass security measures and evade detection. This open-source endpoint detection and response (EDR) tool identifies EDR processes on systems and uses the Windows Filtering Platform (WFP) to manipulate network traffic. Capable of blocking 16 common EDR tools, such as Microsoft Defender, SentinelOne, and Cortex XDR, EDRSilencer is being repurposed by attackers to disrupt communication between security systems and management servers. This tactic enables stealthier ransomware attacks and operational disruptions by muting alerts and avoiding detection, according to TrendMicro researchers.

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/

OWASP ASVS 5.0 Released - Key Updates and What You Need to Know

The OWASP Foundation has released version 5.0 of the Application Security Verification Standard (ASVS), a major update to their security framework for web applications. This new version features restructured security requirements for better clarity, expanded guidance for cloud and API security, improved DevSecOps integration for CI/CD pipelines, updated threat modeling support, and enhanced compliance mapping with standards like NIST and PCI DSS. ASVS serves as a critical benchmark for developers building secure applications, penetration testers conducting security assessments, and auditors performing compliance reviews.  The standard is available for download from the OWASP ASVS project page, with organizations encouraged to integrate it into their software development lifecycles through code reviews and security testing tools. As a vendor-neutral, community-driven project, OWASP continues to welcome contributions to further develop the standard. This release represents an importa...

Open-SPDD proposes an open framework for Spec-Driven Development workflows

Open-SPDD is an open-source project focused on Spec-Driven Product Development, aiming to formalize how software specifications, requirements, architecture, and implementation interact throughout the development lifecycle. The project promotes structured specification management, traceability, and AI-assisted engineering workflows, positioning itself as a foundation for “SpecOps”-style development practices. Its GitHub materials describe SPDD as a way to reduce ambiguity between planning and execution by treating specifications as first-class operational artifacts that can drive automation, validation, and collaboration across engineering teams  https://github.com/gszhangwei/open-spdd
