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. Installation automatically executes a script that fingerprints the host and exfiltrates identity-command output over HTTP. Errors are hidden so the package install can continue. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T13:40:19.502Z - **Finished:** 2026-09-11T13:40:50.744Z - **Download time:** 251 ms - **Static scan time:** 15 ms - **AI review time:** 30975 ms - **Total time:** 31242 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:** Installation automatically executes a script that fingerprints the host and exfiltrates identity-command output over HTTP. Errors are hidden so the package install can continue. - **Trigger:** npm installation, before package installation completes. - **Impact:** A remote server receives the installing account name, host details, working directory, and whoami/id output. - **Evidence paths:** package.json, preinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T13:40:50.744Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Preinstall host fingerprinting and identity-output exfiltration. - **Attack narrative:** On installation, npm invokes preinstall.js. The script gathers the host name, local account name, platform, and current directory and transmits them in an HTTP request to a hard-coded external IP. It then executes whoami and identity commands and posts the resulting output to that same host. The lifecycle command ignores errors, reducing visible installation failure signals. - **Rationale:** This is an automatic install-time host and identity-data exfiltration path with no package functionality that requires it. The empty runtime module does not justify the lifecycle behavior. - **Files touched:** package.json, preinstall.js - **Network endpoints:** http://209.126.81.147/etoro-nuget-verify1f8eaa57a875/npm/v2/${h}/${u}/${p}/${c}, 209.126.81.147:80 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The preinstall hook runs automatically during npm installation and suppresses failures., The lifecycle script collects hostname, username, platform, and current directory, then sends them to an external IP address., It executes system identity commands and posts their output to the same external server. - **Evidence against:** The runtime entry point only exports an empty object., No source writes files, installs dependencies, or loads a second-stage payload. ## Affected versions and remediation This report applies to etoro-cashout@99.0.0. - Avoid installing etoro-cashout@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.
