Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Installation exposes identifying machine and user data to the collector. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 99.9.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 inspected source confirms automatic installation-time disclosure of identifying host and user data to a fixed collector. This is concrete data exfiltration, so the package is malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-20T05:17:45.268Z - **Finished:** 2026-10-20T05:18:06.642Z - **Download time:** 512 ms - **Static scan time:** 5 ms - **AI review time:** 20856 ms - **Total time:** 21374 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 automatically installed dependency discloses host and user identifiers to a fixed OAST collector. - **Trigger:** Installing paychex-pdftron installs its remote ltidisafe dependency, whose preinstall hook runs test.js. - **Impact:** Installation exposes identifying machine and user data to the collector. - **Evidence paths:** package.json, .lpm-dependency-evidence-1e4d3302-fde6-436b-8545-2586f5b6af9c/0/npm-linux/package.json, .lpm-dependency-evidence-1e4d3302-fde6-436b-8545-2586f5b6af9c/0/npm-linux/test.js, .lpm-dependency-evidence-1e4d3302-fde6-436b-8545-2586f5b6af9c/0/npm-linux/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-20T05:18:06.642Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook hex-encodes the hostname, home directory, and username and embeds each value in an HTTP request to the collector. - **Attack narrative:** Installing the package installs a remote dependency with a preinstall hook. That hook collects the machine hostname, home directory, and username, encodes them, and sends them in requests to a fixed OAST collector. - **Rationale:** The inspected source confirms automatic installation-time disclosure of identifying host and user data to a fixed collector. This is concrete data exfiltration, so the package is malicious. - **Files touched:** package.json, .lpm-dependency-evidence-1e4d3302-fde6-436b-8545-2586f5b6af9c/0/npm-linux/package.json, .lpm-dependency-evidence-1e4d3302-fde6-436b-8545-2586f5b6af9c/0/npm-linux/test.js, .lpm-dependency-evidence-1e4d3302-fde6-436b-8545-2586f5b6af9c/0/npm-linux/index.js - **Network endpoints:** http://\.paychex-pdftron.jqdk2ips5i6d14lerg3re3zi99f06oxcm.oastify.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json declares the remote ltidisafe tarball dependency., ltidisafe runs test.js automatically from its preinstall hook., test.js collects and hex-encodes the hostname, home directory, and username., test.js sends those values to a fixed paychex-pdftron OAST subdomain., The dependency's HTTP client makes a request to the supplied URL. ## Affected versions and remediation This report applies to paychex-pdftron@99.9.1. - Avoid installing paychex-pdftron@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.
