Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — If installed in an AWS container, credentials and task metadata may be disclosed to the fixed recipient. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 3.0.7 - **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. The manifest enables npm's implicit native build behavior, and the build action retrieves AWS container credentials and metadata before POSTing them to a fixed external endpoint. This is concrete installation-triggered credential disclosure, so the package should be blocked. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-28T21:20:57.344Z - **Finished:** 2026-10-28T21:21:26.415Z - **Download time:** 261 ms - **Static scan time:** 32 ms - **AI review time:** 28778 ms - **Total time:** 29071 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's native build setup reads AWS container credentials and ECS metadata, then sends the responses to a fixed webhook.site endpoint. - **Trigger:** Installing the package through npm invokes the implicit node-gyp rebuild for its binding.gyp file. - **Impact:** If installed in an AWS container, credentials and task metadata may be disclosed to the fixed recipient. - **Evidence paths:** package.json, binding.gyp - **Review source:** ai\_review - **Reviewed:** 2026-10-28T21:21:26.415Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A binding.gyp action runs Node code that requests container credentials and metadata, then POSTs the responses to webhook.site without a consent check. - **Attack narrative:** During npm installation, the package's native build action can run automatically. It reads the AWS container credential endpoint and ECS metadata when available, then sends the responses to a fixed webhook.site URL. The source shows no consent guard for this transfer. - **Rationale:** The manifest enables npm's implicit native build behavior, and the build action retrieves AWS container credentials and metadata before POSTing them to a fixed external endpoint. This is concrete installation-triggered credential disclosure, so the package should be blocked. - **Files touched:** binding.gyp - **Network endpoints:** https://webhook.site/d6092bdc-05c0-45da-a280-c343ea6d6156, http://169.254.170.2 (AWS container credentials) ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest sets \`gypfile\` to true, enabling npm's implicit node-gyp install behavior., \`binding.gyp\` defines a Node action that runs during the build., The action sends POST requests to a fixed webhook.site URL., It reads the AWS container credential endpoint and posts its response as \`CREDS\`., It also reads ECS task metadata and posts those responses. ## Affected versions and remediation This report applies to spectral-core@3.0.7. - Avoid installing spectral-core@3.0.7. 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.
