AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. This is concrete unconsented install-time telemetry exfiltration, not merely a dormant capability. The inert runtime module does not mitigate the preinstall beacon. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-07-12T11:29:05.328Z - **Finished:** 2026-07-12T11:29:27.907Z - **Download time:** 508 ms - **Static scan time:** 9 ms - **AI review time:** 22061 ms - **Total time:** 22579 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:** An npm preinstall hook exfiltrates install-host identity and the current working directory before package use. It uses HTTP, HTTPS, and DNS fallback channels. - **Trigger:** Installing \`@iana-rzms/bff-sdk@1.0.0\`. - **Impact:** Discloses CI/developer hostname, username, project path, and package resolution to a researcher-controlled host. - **Evidence paths:** package.json, preinstall.js, index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-12T11:29:27.907Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time host metadata beacon - **Attack narrative:** On installation, \`preinstall.js\` gathers \`os.hostname()\`, \`os.userInfo().username\` (or \`USER\`), and \`process.cwd()\`. It base64-encodes those values and sends them to an OAST host via HTTPS, HTTP fallback, and DNS lookup. The hook suppresses failures and terminates quietly, so installations can complete despite the outbound callback. - **Rationale:** This is concrete unconsented install-time telemetry exfiltration, not merely a dormant capability. The inert runtime module does not mitigate the preinstall beacon. - **Files touched:** package.json, preinstall.js, index.js, index.d.ts, README.md - **Network endpoints:** k4pzh6vg78iub3vxqhmml2q8wz2qqge5.oastify.com, poc.k4pzh6vg78iub3vxqhmml2q8wz2qqge5.oastify.com ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** \`package.json\` runs \`node preinstall.js\` during installation., \`preinstall.js\` collects hostname, OS username, and working directory., \`preinstall.js\` encodes and sends that data by HTTPS and HTTP GET., \`preinstall.js\` also performs DNS lookup to \`poc.k4pzh6vg78iub3vxqhmml2q8wz2qqge5.oastify.com\`., Install errors are swallowed, making the beacon non-blocking. - **Evidence against:** \`index.js\` is an inert \`mergeHeaders\` no-op., No file writes, shell execution, secret-file reads, or remote code loading were found. ## Affected versions and remediation This report applies to @iana-rzms/bff-sdk@1.0.0. - Avoid installing @iana-rzms/bff-sdk@1.0.0. 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.
