No network transmission was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 93.0% - **Started:** 2026-07-31T22:56:51.568Z - **Finished:** 2026-07-31T22:57:06.045Z - **Download time:** 511 ms - **Static scan time:** 9 ms - **AI review time:** 13957 ms - **Total time:** 14477 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package runs an inline postinstall command that collects local host metadata and drops it into a temporary file. No network transmission was found. - **Trigger:** npm installation invokes postinstall. - **Impact:** Unconsented installation-time local data collection and filesystem mutation. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-31T22:57:06.045Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time host metadata collection and temporary-file write - **Attack narrative:** The package's postinstall hook executes Node code automatically during installation. It reads host and environment-derived metadata, including username and working directory, then writes it to a temporary file. Although no exfiltration was found, this is an unconsented install-time collection and filesystem-write payload, explicitly framed as a dependency-confusion PoC. - **Rationale:** Source inspection confirms the lifecycle payload and its local metadata collection/write behavior. The benign runtime entrypoint does not mitigate the install-time action. - **Files touched:** package.json, index.js, %TEMP%/mexc-confirmation-dios.txt ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json postinstall runs automatically on installation., It collects hostname, username, current directory, platform, and timestamp., It writes the collected host data to the OS temporary directory., The manifest describes a dependency-confusion proof of concept. - **Evidence against:** index.js only prints a placeholder message., No network or exfiltration endpoint 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 "const o=require('os');const f=require('fs');const p=require('path');f.writeFileSync(p.join(o.tmpdir(),'mexc-confirmation-dios.txt'),'HOST='+o.hostname()+' USER='+(process.... ``` ### 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 o=require('os');const f=require('fs');const p=require('path');f.writeFileSync(p.join(o.tmpdir(),'mexc-confirmation-dios.txt'),'HOST='+o.hostname()+' USER='+(process.... ``` ### 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. 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:** mx-biz-hot - **Ecosystem:** npm - **Version:** 1.0.0 - **License:** UNLICENSED - **Version published:** 2026-07-31T16:01:43.386Z - **Package first seen:** 2026-07-31T22:57:06.045Z - **Package last seen:** 2026-07-31T22:57:06.045Z - **Known versions:** 1 - **Latest version:** 1.0.0 - **Appeal under review:** No - **Description:** Security placeholder to prevent dependency confusion on mx-biz-hot.
