Based solely on the provided evidence, we cannot definitively label the package @csstools/postcss-initial version 2.0.1 as malware. Evidence 0 highlights a lack of source project information. This is insufficient to conclude malicious intent. The absence of project information could be due to several benign reasons: the project is very new, the repository is private, or our database is incomplete. Without additional evidence such as suspicious code behavior (e.g., network connections, file system modifications, or execution of arbitrary code) detected through static or dynamic analysis, or a positive identification from reliable malware detection tools (LLM analysis or other advanced techniques beyond YARA, which is noted as unreliable), we cannot confidently classify this package as malicious. Further investigation is required.
