The package is not a malware. While there are multiple YARA rule matches, including http_url_with_msi and POST_command_executer, these are low confidence. The presence of embedded executables (fastlist-0.3.0-x64.exe and fastlist-0.3.0-x86.exe) is suspicious, but there are legitimate use cases for embedding executables. The python_exec_complex matches are on javascript files, which is a known false positive. Furthermore, the project has a high number of stars and forks, and a verified SLSA provenance, suggesting it is a legitimate and well-maintained package.
