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 opens an interactive Bash connection to a remote host and performs an HTTP POST. This is a concrete install-time remote shell and outbound network action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T09:59:54.099Z - **Finished:** 2026-09-11T10:00:37.292Z - **Download time:** 503 ms - **Static scan time:** 9 ms - **AI review time:** 42680 ms - **Total time:** 43193 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 opens an interactive Bash connection to a remote host and performs an HTTP POST. This is a concrete install-time remote shell and outbound network action. - **Trigger:** npm package installation - **Impact:** A remote party can interact with the installer shell under the installing user's privileges. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-11T10:00:37.292Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** preinstall reverse shell over Bash TCP redirection - **Attack narrative:** During npm installation, preinstall starts interactive Bash and redirects its input and output through a TCP connection to 147.93.157.202 on port 8080. The command also attempts to POST data to a Canarytokens endpoint. The hook is automatic and grants a remote endpoint shell interaction with the privileges of the installer. - **Rationale:** The manifest contains an automatic preinstall reverse-shell command to an external IP, plus an outbound POST. The claimed canary purpose does not provide consent or make this install-time behavior safe. - **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 automatic preinstall hook launches interactive Bash with standard input and output redirected to a remote TCP socket., The same install hook makes an outbound POST to a Canarytokens URL., The lifecycle behavior runs on package installation without an explicit user command. - **Evidence against:** test.js runs id only if someone manually executes that unreferenced file., The package description calls it a canary, but that does not establish consent for the install-time reverse shell. ## Affected versions and remediation This report applies to @nimbusedge/auth@19999.0.4. - Avoid installing @nimbusedge/auth@19999.0.4. 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.
