Based solely on the provided evidence, there is insufficient information to classify @excalidraw/excalidraw version 0.18.0 as malware. Evidence 0 highlights a lack of source project information, which is a low-confidence indicator. This could be due to several benign reasons: the package is newly published, the project information is not yet indexed in our database, or the source project is private. The absence of additional evidence, such as suspicious file contents (LLM analysis or YARA results), or unusual behavior during execution, prevents a definitive malware classification. More investigation is needed, including examining the package's code for malicious functionality and verifying its provenance through alternative means.
