AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package automatically queries the cloud metadata service for instance data and a concealed security-credentials path, then saves the responses locally. This collection occurs on startup without an explicit user request. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-31T17:26:40.466Z - **Finished:** 2026-10-31T17:27:06.062Z - **Download time:** 520 ms - **Static scan time:** 28 ms - **AI review time:** 25047 ms - **Total time:** 25596 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:** Automatically collects cloud instance metadata, including a security-credentials path, and saves the responses locally. - **Trigger:** index.js import or startup. - **Impact:** May collect cloud instance identifiers and credentials into a file in the working directory without an explicit request. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-31T17:27:06.062Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Requests a metadata token and queries http://100.100.100.200/latest/meta-data/ paths, then writes returned response text to output/meta\_field\_dump.txt. - **Attack narrative:** When index.js loads, it automatically queries the Alibaba ECS metadata service, including a path decoded from base64 that targets security credentials. It records successful response bodies in output/meta\_field\_dump.txt. The inspected code does not show the collected contents being sent elsewhere, but automatic collection of cloud metadata credentials is itself malicious under the review criteria. - **Rationale:** The package automatically queries the cloud metadata service for instance data and a concealed security-credentials path, then saves the responses locally. This collection occurs on startup without an explicit user request. - **Files touched:** output/meta\_field\_dump.txt - **Network endpoints:** http://100.100.100.200/latest/api/token, http://100.100.100.200/latest/meta-data/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The code decodes a hidden metadata path and adds it to the list of fields to collect., At startup, it requests Alibaba ECS metadata, including the security-credentials path., It writes successful metadata response bodies to output/meta\_field\_dump.txt., The metadata collection starts automatically when index.js loads. - **Evidence against:** The manifest has no install, preinstall, or postinstall script., The inspected source stores the metadata dump locally; no transmission of the collected response bodies to another host was identified. ## Affected versions and remediation This report applies to @ifasn/mdd-doc-mcp@2.0.6. - Avoid installing @ifasn/mdd-doc-mcp@2.0.6. 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.
