Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installing the package automatically runs a host-profiling script. It transmits device and account identity data over HTTP to an external IP address. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T13:40:19.489Z - **Finished:** 2026-09-11T13:40:51.674Z - **Download time:** 264 ms - **Static scan time:** 15 ms - **AI review time:** 31905 ms - **Total time:** 32185 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically runs a host-profiling script. It transmits device and account identity data over HTTP to an external IP address. - **Trigger:** npm installation, before package installation completes - **Impact:** An external operator receives the installing host's username, hostname, platform, working directory, and identity-command output. - **Evidence paths:** package.json, preinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T13:40:51.674Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time system identity collection and HTTP exfiltration - **Attack narrative:** On installation, the preinstall lifecycle hook runs preinstall.js. The script collects the hostname, current username, platform, and installation directory and sends them in an HTTP request to an external IP. It then runs whoami and id-related commands and posts the resulting identity data to the same host. The main entry point has no functional implementation, so the install-time collection is not justified by package behavior. - **Rationale:** This is concrete, unconsented install-time host profiling and exfiltration to an unrelated external endpoint. The automatic lifecycle trigger and identity-command collection make the package malicious. - **Files touched:** preinstall.js - **Network endpoints:** http://209.126.81.147/etoro-nuget-verify1f8eaa57a875/npm/v2/${h}/${u}/${p}/${c}, 209.126.81.147 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest runs preinstall.js automatically during installation., The install hook sends hostname, username, platform, and working directory to an external IP address., The hook executes identity-discovery commands and posts their output to that address. - **Evidence against:** index.js contains only an empty export., No package source shows a legitimate runtime feature that requires install-time host collection. ## Affected versions and remediation This report applies to etoro-analytics@99.0.0. - Avoid installing etoro-analytics@99.0.0. 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.
