Its postinstall hook runs on npm install using `node postinstall.js || true` and sends encoded hostname, working-directory, platform, runtime-version, and username data as DNS labels to `oob.s4yhii.com`, making it a dependency-confusion probe that collects environment data. The npm account s4yhii_ published it on 2026-10-08.\n\n---\n_-= Per source details. Do not edit below this line.=-_\n\n## Source: amazon-inspector (64345fa1c5c24196376e1a0cc8c14b6dcf3898e972b0b6fc23ae8f19d67b6f11)\nOn `npm install`, this package's `postinstall` script (node postinstall.js) hex-encodes the installer's hostname, current working directory, platform/arch/Node version, and USER/USERNAME/LOGNAME values, and emits DNS queries whose subdomains encode that data under the hardcoded author-controlled zone `oob.s4yhii.com`, using an authoritative resolver as an out-of-band exfiltration channel. The package name and the version number `999.0.3` are consistent with a dependency-confusion payload shape designed to win resolution against an internal `@galicia-toolkit/error-master` package. The DNS-tunnel beacon fires automatically at install time with no installer action beyond `npm install`, leaking host and user identifiers to the attacker's authoritative nameserver.\n\n## Source: ghsa-malware (26405e431ce3fc8ada12515c167aa0fcc8205369a5b43e6097db28fe579f3784)\nAny computer that has this package installed or running should be considered fully compromised.
