The package contains an embedded executable (package/bin/esbuild) which is unusual for a typical NPM package. The file extension mismatch and the high entropy trailer detected by the YARA rule further raise suspicion. While embedded executables can have legitimate uses, the combination of these three factors suggests a higher risk of malicious intent. The high entropy trailer, in particular, hints at potential code injection or obfuscation, which is commonly seen in malware.
