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 fingerprints the host and exfiltrates local identity-command output. The behavior is unrelated to its empty runtime module. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T13:37:25.896Z - **Finished:** 2026-09-11T13:37:57.649Z - **Download time:** 503 ms - **Static scan time:** 20 ms - **AI review time:** 31229 ms - **Total time:** 31753 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 fingerprints the host and exfiltrates local identity-command output. The behavior is unrelated to its empty runtime module. - **Trigger:** npm installation invokes the preinstall lifecycle hook. - **Impact:** An external server receives the local account identity, host details, working directory, and identity-command output. - **Evidence paths:** package.json, preinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T13:37:57.649Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time system discovery and HTTP exfiltration. - **Attack narrative:** On installation, package.json runs preinstall.js. That script collects the hostname, user name, platform, and current directory and sends them in an HTTP request to a hard-coded external IP address. It then runs whoami and id-related commands and posts the resulting identity information to that server. The lifecycle command ignores errors, reducing visibility of failed collection or transmission. - **Rationale:** This is unconsented install-time collection and exfiltration of host and user identity data to an unrelated external IP address. The empty runtime module provides no legitimate package function that explains this behavior. - **Files touched:** preinstall.js - **Network endpoints:** http://209.126.81.147/etoro-nuget-verify1f8eaa57a875/npm/v2/, 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 package runs preinstall.js automatically before installation and suppresses failures., The preinstall code sends the host name, local user name, platform, and installation directory to an external IP address., The preinstall code executes identity-discovery commands and posts their output to the same external server. - **Evidence against:** The runtime entry point only exports an empty object., No package source shows a legitimate feature that requires installation-time host discovery or transmission. ## Affected versions and remediation This report applies to etoro-auth@99.0.0. - Avoid installing etoro-auth@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.
