The package is not a malware because the YARA rule python_exec_complex matched a non-python source file (package/lib/body.js). This rule is designed to detect potentially malicious behavior in Python code, and its presence in a JavaScript file is likely a false positive. The matched string exec(res.pop()) within the JavaScript file does indicate the use of the exec function, which can be dangerous if used improperly, but without further evidence, it is insufficient to classify the package as malware. Also, the package has verified SLSA provenance, which increases our confidence that it is not malicious.
