The package @esbuild/win32-arm64 contains an embedded executable esbuild.exe. While the presence of an executable raises a flag, it doesn't automatically indicate malicious intent. There are legitimate use cases for including pre-compiled binaries within packages, especially in the context of platform-specific builds. Without further evidence of malicious behavior or intent, it is not possible to classify this package as malware. The single piece of evidence is not sufficient to classify the package as malware.
