The query string includes `os.hostname()` (truncated to 200 chars) plus the package name, version, a nonce, and a phase identifier. This fires automatically on every install with no opt-out. The package self-describes as a 'dependency-confusion canary,' but it is published on the public npm registry under the `@demica/*` scope: any installer that resolves `@demica/resources` — including via accidental dependency confusion, typo, or curiosity install — will leak their hostname to the operator of that bare IP over unencrypted HTTP. The destination is an anonymous bare IP with no associated domain, publisher, or disclosure; hostname is an installer-side host identifier transmitted off-host to an attacker-shaped endpoint.\n\n## Source: ghsa-malware (d2b5202f5f3ce17b513e7c5cd30af6dbe5db49b09ee62082b2f51bba7f7ea6b3)\nAny computer that has this package installed or running should be considered fully compromised.
