Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package brings in a remote dependency with an automatic preinstall hook that sends machine and user identifiers to an OAST endpoint. This is concrete installation-time data 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:** 2026-10-19T05:45:55.014Z - **Finished:** 2026-10-19T05:46:24.862Z - **Download time:** 1557 ms - **Static scan time:** 5 ms - **AI review time:** 28286 ms - **Total time:** 29848 ms The recorded confidence comes from the underlying analysis.

Its preinstall hook runs a helper that encodes the machine hostname, home directory, and username, then sends requests to a subdomain of an OAST collector. This is automatic installation-time disclosure; no recipient-specific consent guard appears in the inspected path. - **Rationale:** The package brings in a remote dependency with an automatic preinstall hook that sends machine and user identifiers to an OAST endpoint. This is concrete installation-time data disclosure, so the package should be blocked. - **Network endpoints:** postex-common.ltim5ksu8k9f46ogui6th52kcbi96zuo.oastify.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package manifest installs a dependency from a remote tarball., That dependency runs a helper automatically during preinstall., The helper reads the machine hostname, home directory, and username, then sends each value to a subdomain of an OAST collector., The network speed helper makes an HTTP request to the supplied URL, carrying those values in the subdomain. ## Affected versions and remediation This report applies to @postex/common@99.9.1. - Avoid installing @postex/common@99.9.1. 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.
