AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection confirms concrete install-time collection and exfiltration of host identity data to an external endpoint. This is malicious behavior, not merely suspicious network capability. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-07-09T16:18:51.813Z - **Finished:** 2026-07-09T16:20:40.690Z - **Download time:** 255 ms - **Static scan time:** 9 ms - **AI review time:** 108612 ms - **Total time:** 108877 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 exfiltrates host fingerprint data during npm installation. The behavior is triggered by a postinstall lifecycle hook and sends data to an external OAST endpoint. - **Trigger:** npm install runs package.json postinstall: node index.js - **Impact:** Leaks installer hostname, username, current working directory, local IPv4 address, and package name to an attacker-controlled endpoint. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-09T16:20:40.690Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time host fingerprint collection and HTTP POST exfiltration - **Attack narrative:** On installation, npm runs the postinstall script \`node index.js\`. That script reads local host and user identifiers, serializes them as JSON, and sends them via HTTP POST to an external oast.fun endpoint. This is unconsented install-time reconnaissance and data exfiltration with no legitimate package functionality present. - **Rationale:** Source inspection confirms concrete install-time collection and exfiltration of host identity data to an external endpoint. This is malicious behavior, not merely suspicious network capability. - **Files touched:** package.json, index.js - **Network endpoints:** http://lpzlajzjfkpfeefuzxbv6n5nob7bpuh6e.oast.fun:80/receive-data ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json defines postinstall: node index.js, causing install-time execution., index.js collects hostname, cwd, username, and non-internal IPv4 address., index.js POSTs collected host data to lpzlajzjfkpfeefuzxbv6n5nob7bpuh6e.oast.fun/receive-data over HTTP., No package-aligned functionality or user consent explains host fingerprint exfiltration. - **Evidence against:** No child\_process, eval, dynamic require, native binary loading, persistence, or destructive file writes observed., Package contains only package.json and index.js. ## Affected versions and remediation This report applies to testing-d3do@99.9.9. - Avoid installing testing-d3do@99.9.9. 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.
