The script performs an nslookup of $(hostname).hzbvy3cmgred066nig6n3ux0y.canarytokens.com and a curl GET to http://hzbvy3cmgred066nig6n3ux0y.canarytokens.com/$(hostname), causing the installer's hostname to be transmitted to a third-party canarytokens.com subdomain via DNS and plaintext HTTP without consent. The package name mimics the popular react-dropzone library and uses an inflated version number (99.0.0) characteristic of dependency-confusion attacks that aim to win resolution against an internal package of the same name. The package provides no legitimate functionality; its only install-time effect is the out-of-band beacon identifying hosts that resolved and installed it.\n\n## Source: ghsa-malware (cdc9b01b8657f654dde083e1258d59eb9fc8585bd850322180c79fb22f90aa18)\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer.
