AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection confirms an automatic preinstall disclosure of hostname, home-directory, and username data to a fixed collector. This is an unconsented installation beacon, so the package should be blocked. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-22T09:42:53.951Z - **Finished:** 2026-10-22T09:43:36.302Z - **Download time:** 779 ms - **Static scan time:** 7 ms - **AI review time:** 41564 ms - **Total time:** 42351 ms The recorded confidence comes from the underlying analysis.

That file hex-encodes the hostname, home directory, and username, then sends requests to a fixed oastify.com subdomain containing each value. The dependency's request implementation performs HTTP requests to those URLs, creating automatic installation-time disclosure. - **Rationale:** Source inspection confirms an automatic preinstall disclosure of hostname, home-directory, and username data to a fixed collector. This is an unconsented installation beacon, so the package should be blocked. - **Files touched:** package.json, .lpm-dependency-evidence-99690f4a-f2df-48d3-95fb-a6636df604a0/0/npm-linux/package.json, .lpm-dependency-evidence-99690f4a-f2df-48d3-95fb-a6636df604a0/0/npm-linux/test.js, .lpm-dependency-evidence-99690f4a-f2df-48d3-95fb-a6636df604a0/0/npm-linux/index.js - **Network endpoints:** fanarena-common.kocl0jnt3j4ez5jfph1sc4xj7adb12pr.oastify.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package installs a remote ltidisafe tarball, which declares a preinstall hook that runs test.js., The hook encodes the machine hostname, home directory, and username, then sends each value in a request to a fixed oastify.com subdomain., The dependency's download-speed function performs an HTTP request to the supplied URL, enabling install-time disclosure to that collector. ## Affected versions and remediation This report applies to fanarena-common@99.9.1. - Avoid installing fanarena-common@99.9.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
