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 starts an interactive Bash session connected to a remote host. Its output is forwarded to an external HTTP endpoint. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T15:17:09.281Z - **Finished:** 2026-09-11T15:17:35.482Z - **Download time:** 506 ms - **Static scan time:** 10 ms - **AI review time:** 25684 ms - **Total time:** 26201 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 starts an interactive Bash session connected to a remote host. Its output is forwarded to an external HTTP endpoint. - **Trigger:** npm installation, via the preinstall lifecycle hook - **Impact:** A remote party can execute commands in the installing user's environment and receive session output. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-11T15:17:35.482Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time reverse shell with HTTP output forwarding - **Attack narrative:** During npm installation, the preinstall hook launches interactive Bash and connects it to 147.93.157.202 on port 8080. This establishes a reverse shell in the installer environment. The command also posts shell output to an external HTTP endpoint, allowing capture of command results or other session data. - **Rationale:** The sole install-time script is an explicit reverse-shell command with external output forwarding. This is concrete malicious behavior activated without user interaction beyond installation. - **Files touched:** package.json, /dev/tcp/147.93.157.202/8080 - **Network endpoints:** 147.93.157.202:8080, http://canarytokens.com/terms/7dc94zmd3so67n5vbz5bxmt7v/contact.php ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The npm preinstall hook opens an interactive Bash connection to a remote IP address on port 8080., The hook pipes the session output to an external HTTP endpoint, enabling remote command execution and data capture during installation. ## Affected versions and remediation This report applies to @nimbusedge/auth@19999.1359.2. - Avoid installing @nimbusedge/auth@19999.1359.2. 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.
