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.

The Hidden Cost of DevSecOps: Time and Financial Burden of Security on Developers

 A survey by JFrog, "The Hidden Cost of DevSecOps: A Developer’s Time Assessment," reveals that developers spend a significant amount of time on security-related tasks, costing companies around $28,000 per developer annually. Half of senior developers and team leaders report a notable increase in weekly hours dedicated to security tasks like manual application scans, context switching, and secrets detection. This time detracts from innovation and delivering new applications. JFrog’s CTO, Asaf Karas, emphasized the inefficiency caused by juggling multiple tools and environments, advocating for streamlined security processes to boost efficiency and reduce risks. Many developers spend 19% of their weekly hours on security tasks, often outside regular work hours, resulting in a reactive approach to security. https://informationsecuritybuzz.com/the-hidden-price-of-devsecops/

OWASP Releases Enhanced Dependency-Check Tool with Advanced Tagging and Policy Management Features

 OWASP has released an updated version of its dependency-check tool, version 4.12.0, which identifies vulnerabilities in third-party software components, enforces policy compliance, and generates a CycloneDX-based Software Bill of Materials (SBOM). Key updates include enhanced tag features for improved control over security alerts and SBOM validation, a new tag management view, a global policy violation audit view, and authorization for security status badges. These changes offer more granular control over managing third-party dependencies, though experts note that managing software risk remains an ongoing challenge despite these improvements. https://securityboulevard.com/2024/10/owasps-dependency-check-tool-update-key-changes-and-limitations/ ps.  I think Security Boulevard (https://securityboulevard.com/) is a little bit confused here. https://securityboulevard.com/2024/10/owasps-dependency-check-tool-update-key-changes-and-limitations/ The original news links to Dependency Track in
