No network endpoint or payload execution is present. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 94.0% - **Started:** 2026-07-31T22:59:09.098Z - **Finished:** 2026-07-31T22:59:26.144Z - **Download time:** 769 ms - **Static scan time:** 9 ms - **AI review time:** 16268 ms - **Total time:** 17046 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation runs a Node one-liner that collects basic host metadata and drops a local confirmation file. No network endpoint or payload execution is present. - **Trigger:** npm installation, via postinstall - **Impact:** Creates a local proof artifact containing basic host context without user consent. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-31T22:59:26.144Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time host metadata collection and temp-file write - **Rationale:** Source inspection confirms an install-time local metadata collection and write, but no concrete exfiltration, remote code execution, persistence, or destructive action. This warrants a warning rather than a block. - **Files touched:** package.json, index.js, OS temp directory/mexc-confirmation-dios.txt ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json defines an unconsented postinstall hook., The hook collects hostname, username, cwd, platform, and time., The hook writes mexc-confirmation-dios.txt into the OS temp directory., package.json describes a dependency-confusion proof of concept. - **Evidence against:** index.js only logs a placeholder message., No network, credential exfiltration, remote execution, persistence, or destructive behavior found., The postinstall payload is deterministic and writes only a local proof file. ## 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{execSync}=require('child_process');const o=require('os');const f=require('fs');const p=require('path');const pf=p.join(o.tmpdir(),'mexc-confirmation-dios.txt');const... ``` ### 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{execSync}=require('child_process');const o=require('os');const f=require('fs');const p=require('path');const pf=p.join(o.tmpdir(),'mexc-confirmation-dios.txt');const... ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 5. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 70.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 6. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ## 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:** @mexc/ws - **Ecosystem:** npm - **Version:** 1.0.0 - **License:** UNLICENSED - **Version published:** 2026-07-31T15:22:21.623Z - **Package first seen:** 2026-07-31T22:59:26.144Z - **Package last seen:** 2026-07-31T22:59:29.851Z - **Known versions:** 2 - **Latest version:** 1.0.1 - **Appeal under review:** No - **Description:** Security placeholder — prevents dependency confusion on @mexc/ws.
