      "value": "Hatching Triage Sandbox Windows 10 build 2004 (2025-08-14) and Windows 10 LTSC 2021(2025-08-14) contains a vulnerability in its Windows behavioral analysis engine that allows a submitted malware sample to evade detection and cause denial-of-analysis. The vulnerability is triggered when a sample recursively spawns a large number of child processes, generating high log volume and exhausting system resources. As a result, key malicious behavior, including PowerShell execution and reverse shell activity, may not be recorded or reported, misleading analysts and compromising the integrity and availability of sandboxed analysis results."

      "value": "Hatching Triage Sandbox Windows 10 build 2004 (2025-08-14) y Windows 10 LTSC 2021 (2025-08-14) contiene una vulnerabilidad en su motor de análisis de comportamiento de Windows que permite a una muestra de malware enviada evadir la detección y causar una denegación de análisis. La vulnerabilidad se activa cuando una muestra genera recursivamente un gran número de procesos hijo, generando un alto volumen de registros y agotando los recursos del sistema. Como resultado, el comportamiento malicioso clave, incluyendo la ejecución de PowerShell y la actividad de shell inverso, puede no ser registrado o reportado, engañando a los analistas y comprometiendo la integridad y disponibilidad de los resultados del análisis en sandbox."
