These levels help to assess the potential impact of each sample on the environment where they are executed. Below is a description of each severity level: **LOW** Files that are detected by signature-based security tools are considered to have low severity. Their behavior does not suggest any significant impact on the host where they were executed. **MIDDLE** Files that may or may not be detected by signature-based security tools are classified as medium severity. These files may be detected by heuristics, and their behavior suggests a non-serious impact on the host. They may also exhibit obfuscation. **HIGH** Files that are not detected by signature-based security tools but can be detected by heuristics are considered high severity. These files often have obfuscation, and their execution may be partial or complete, resulting in a visible and significant impact on the host where they were executed. **CRITICAL** Customized or modified artifacts that are not detected by signature-based security tools or heuristics are classified as critical severity. These files typically have obfuscation, are fully executed, and have a considerable impact on the host, including the potential for callbacks and evasion of enforced network security. **ZERO-DAY** Artifacts created by EVE/REVEALD that are modified and can be obfuscated are classified as zero-day severity. These files are not detected by signature-based security tools or heuristics, are fully executed, and have a significant impact on the host. They may also include callbacks and enforce network security evasion. {% hint style="danger" %} Zero-day samples are not part of any licening model. These samples are available only uppon customer request and are licensed separately. {% endhint %} --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.reveald.com/technical-documentation/admin-guides/epiphany-validation-engine-users-guide/chapter-3-eve-platform/navigation-tabs/emulation-control/threat-library/artifacts-severity.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
