leo-logger @1.0.8

Summary

The package's binding.gyp contains GYP command-expansion syntax ( <!(...) / <!@(...) ) at line 6 inside a sources/targets field. npm implicitly runs node-gyp rebuild whenever a binding.gyp is present — even with no declared install/postinstall script — and GYP evaluates these expressions as shell commands during the configure step. This causes the embedded command to execute on every npm install of this package, functionally equivalent to a malicious lifecycle hook. The package presents itself as a 'logger' but ships no native C/C++ source that would justify a node-gyp build configuration, so the binding.gyp's only effective purpose is to trigger command execution at install time.
