Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Remote code execution and likely credential exfiltration during installation. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 7.1.2 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The preinstall hook deliberately bootstraps and executes an unrelated obfuscated payload, including remote code evaluation and credential-related logic. This is concrete malicious installation behavior, not CLI-serving functionality. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-04T10:57:09.977Z - **Finished:** 2026-08-04T10:57:47.871Z - **Download time:** 1274 ms - **Static scan time:** 3404 ms - **AI review time:** 33214 ms - **Total time:** 37894 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:** npm installation triggers a downloader that executes an obfuscated secondary payload. That payload includes remote-response evaluation and credential-token handling. - **Trigger:** npm preinstall - **Impact:** Remote code execution and likely credential exfiltration during installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T10:57:47.871Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloaded Bun executes obfuscated payload with remote eval - **Attack narrative:** Installing the package runs setup.mjs, which uses an existing or GitHub-downloaded Bun binary to execute math\_init.js. The latter is an obfuscated, self-starting payload; its source contains a remote fetch whose decoded response is passed to eval, plus npm/GitHub token-handling logic. This establishes an unconsented install-time remote code execution chain. - **Rationale:** The preinstall hook deliberately bootstraps and executes an unrelated obfuscated payload, including remote code evaluation and credential-related logic. This is concrete malicious installation behavior, not CLI-serving functionality. - **Files touched:** package.json, setup.mjs, math\_init.js - **Network endpoints:** https://github.com/oven-sh/bun/releases/download/bun-v1.3.13/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json runs \`node setup.mjs\` at preinstall., setup.mjs downloads a Bun binary from GitHub and executes \`math\_init.js\`., math\_init.js is heavily obfuscated and self-invokes at load., math\_init.js fetches remote content and evaluates its decoded body., math\_init.js contains token-handling paths for npm and GitHub credentials., The install path has no package-serving justification for this payload runner. - **Evidence against:** lib/serve.js is a conventional local development server., The only plainly identified setup download host is github.com/oven-sh/bun. ## Affected versions and remediation This report applies to @nebula.js/cli-serve@7.1.2. - Avoid installing @nebula.js/cli-serve@7.1.2. 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.
