Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — The OAST endpoint can receive identifying information about the installing user and machine. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 1.2.3 - **Selected version is latest:** Yes - **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 activates the behavior during installation, and the source shows an automatic DNS disclosure of local identifiers to an unrelated OAST collector without a consent gate. This supports blocking as install-hook abuse. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-27T12:47:27.977Z - **Finished:** 2026-10-27T12:47:54.065Z - **Download time:** 768 ms - **Static scan time:** 1068 ms - **AI review time:** 24252 ms - **Total time:** 26088 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 preinstall hook automatically discloses the machine username and hostname through a DNS lookup to an OAST domain. - **Trigger:** Installing the package when npm runs its preinstall hook. - **Impact:** The OAST endpoint can receive identifying information about the installing user and machine. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-27T12:47:54.065Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** index.js builds a DNS name containing the sanitized username and hostname, then calls dns.lookup on it without a consent check. - **Attack narrative:** During package installation, the preinstall hook runs index.js. That script puts the local username and hostname into a DNS name and looks it up under an OAST domain, disclosing identifying information without installer consent. - **Rationale:** The manifest activates the behavior during installation, and the source shows an automatic DNS disclosure of local identifiers to an unrelated OAST collector without a consent gate. This supports blocking as install-hook abuse. - **Files touched:** package.json, index.js - **Network endpoints:** msrc-poc.\.\.dbg6vplohjpkmtolbi6g18ekofkxjzm4s.oast.fun ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json runs index.js automatically during preinstall., index.js collects the local username and hostname and places them in a DNS name under an OAST domain., index.js sends that name through a DNS lookup without a consent check. ## Affected versions and remediation This report applies to @azure-growth/signup-ux-components@1.2.3. - Avoid installing @azure-growth/signup-ux-components@1.2.3. 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.
