The package @img/sharp-libvips-linuxmusl-x64 version 1.2.3 is likely not malware. While it contains an embedded executable (libvips-cpp.so.8.17.2) and exhibits an extension mismatch, the project sharp-libvips has a reasonable number of stars (200) and forks (113) on GitHub, suggesting it's a legitimate project. The SLSA provenance is also verified. The embedded executable is likely a pre-compiled binary, which is a valid use case. The extension mismatch is unusual but not necessarily indicative of malicious intent.
