A package installation can introduce unreviewed instructions/extensions into detected Codex, Claude Code, and Cursor environments. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.6.5 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm postinstall, the package downloads a native archive, installs its binary, and attempts to globally install a downloaded agent skill. This mutates multiple foreign AI-agent control surfaces without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 94.0% - **Started:** 2026-08-11T10:28:12.573Z - **Finished:** 2026-08-11T10:28:52.155Z - **Download time:** 762 ms - **Static scan time:** 74 ms - **AI review time:** 38745 ms - **Total time:** 39582 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm postinstall, the package downloads a native archive, installs its binary, and attempts to globally install a downloaded agent skill. This mutates multiple foreign AI-agent control surfaces without an explicit user command. - **Trigger:** npm install / postinstall - **Impact:** A package installation can introduce unreviewed instructions/extensions into detected Codex, Claude Code, and Cursor environments. - **Evidence paths:** package.json, lib/install.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-11T10:28:52.155Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary installation plus global agent-skill registration - **Attack narrative:** The postinstall hook fetches a platform-native release archive from GitHub, verifies it using a checksum fetched from the same release location, extracts it, and executes the binary for version verification. It then copies a downloaded skill and invokes a global skills installer. The README confirms this targets detected Codex, Claude Code, and Cursor agents, so ordinary dependency installation can alter broad external agent control surfaces. - **Rationale:** This is unconsented postinstall mutation of foreign/broad AI-agent environments, coupled with remote native payload installation. The source establishes the behavior directly. - **Files touched:** package.json, lib/install.js, README.md, ~/.tier0/bin/tier0, ~/.tier0/bin/.version, ~/.tier0/skills/ - **Network endpoints:** https://github.com/FREEZONEX/Tier0-cli/releases/download/ ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs lib/install.js automatically in postinstall., lib/install.js downloads and executes a release binary during postinstall., lib/install.js extracts a downloaded SKILL.md into ~/.tier0/skills., lib/install.js automatically runs global \`skills add\` for detected agents., README.md states it copies skills to Codex, Claude Code, and Cursor. - **Evidence against:** Release version is pinned to the npm package version., Downloaded archive is SHA-256 checked, though the checksum is fetched from the same release host., No source evidence of credential harvesting or arbitrary data exfiltration. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node lib/install.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node lib/install.js ``` ### 3. Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 4. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 5. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 6.

Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 8. High: Unverified Remote Native Payload Install - **Category:** Source - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() Install-time source downloads a native archive from a fixed external host without transport verification, extracts it, and installs an executable payload. Public source snippet (untrusted): ```json scripts.postinstall = node lib/install.js Install-time code downloads an unverified remote native executable, stages it locally, activates an executable path, and exposes it to process execution. L4: const path = require('path'); L5: const https = require('https'); L6: const crypto = require('crypto'); L7: const { execFileSync, execSync, spawn } = require('child_process'); L8: ... L62: } else { L63: fs.copyFileSync(srcPath, dstPath); L64: } ... L70: return new Promise((resolve, reject) => { L71: const file = fs.createWriteStream(dest); L72: https.get(url, { timeout: 300000 }, (res) => { L73: if (res.statusCode === 302 || res.statusCode === 301) { ``` ### 9. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 10.
