Analysis
The preinstall hook runs a bundled script that issues an HTTP GET to hxxp://209[.]126[.]81[.]147/etoro-depconf-poce346552f776f/npm/{hostname}/{username}/{cwd}, exfiltrating the install machine's hostname, username, and working directory to a remote IP. The package is a 562-byte stub published at version 999.0.0 under a name impersonating eToro's internal package, with no repository or documentation.
