The package @esbuild/linux-x64 contains an embedded executable package/bin/esbuild. While this raises a potential security concern, it's a common practice for legitimate packages to include pre-compiled binaries. Without further evidence of malicious behavior, it's not possible to classify this package as malware. The esbuild project is also a popular project with a large number of stars and forks, which increases the likelihood that this is a legitimate use case.
