⚠️ SECURITY ALERT: Fake OpenClaw App Has Been Stealing Your OpenAI Tokens

If you’ve installed anything called “OpenClaw Codex Claude AI Agent” from an unofficial source — or if you’ve used an npm package named codexui-android in the last month — your OpenAI authentication tokens may be in the hands of attackers. Act now.

Researchers at Aikido Security discovered that the codexui-android npm package, which had amassed approximately 27,000 weekly downloads, was silently exfiltrating OpenAI OAuth refresh tokens to an attacker-controlled server. The package presented itself as a legitimate, polished remote web UI for OpenAI Codex — real GitHub repository, active development, functional enough that developers genuinely wanted to use it. That’s what made it so dangerous.

A linked Android app — explicitly named “OpenClaw Codex Claude AI Agent” — used the same exfiltration infrastructure, targeting users on mobile devices running in a Termux/PRoot Linux environment. Ox Security also flagged related OpenClaw phishing campaigns during this period. The goal: steal OAuth refresh tokens and ship them to a fake Sentry endpoint, giving attackers persistent access to your OpenAI account even if you later change your password.

This was a supply chain attack dressed up as a community contribution. It is directly targeting OpenClaw users by name.

Step 1: Check if You Have the Malicious npm Package

Open your terminal and run the following commands to check for the malicious package:

# Check for global installation
npm list -g codexui-android

# Check for local installation in your current project
npm list codexui-android

# Broader search across all local node_modules (run from a parent directory)
find . -name "node_modules" -prune -o -name "package.json" -print | xargs grep -l "codexui-android" 2>/dev/null

If any of these return a result, the package is installed. Proceed to removal immediately.

Step 2: Remove the Malicious Package

# Uninstall from global scope
npm uninstall -g codexui-android

# Uninstall from a local project
npm uninstall codexui-android

# Verify it's gone
npm list -g codexui-android

After removal, do not trust any node_modules directory in a project that included this package. Consider running npm audit to check for other suspicious dependencies.

Step 3: Check Your Android Device

The fake Android app circulated under the name “OpenClaw Codex Claude AI Agent”. This app was NOT published through official channels — it was distributed via sideloading and unofficial APK sites.

To check:

  1. Go to Settings → Apps (or Application Manager) on your Android device
  2. Search for any app containing the words “OpenClaw,” “Codex,” or “Claude AI Agent” that you don’t recognize as an official app
  3. Check your downloads folder for any .apk files you may have installed from unofficial sources

If you find the app, uninstall it immediately, then revoke your tokens (see Step 4).

Step 4: Revoke Your OpenAI API Keys and Refresh Tokens

This is the most critical step regardless of whether you found the malicious software. If you’ve used codexui-android or the fake app at any point in the last 30 days, assume your tokens are compromised.

Revoke API Keys

  1. Go to https://platform.openai.com/api-keys
  2. Delete every key that could have been exposed — don’t just rotate them, delete and recreate
  3. Generate new keys with minimum required permissions for each use case
  4. Update your applications and environment variables with the new keys

Invalidate OAuth Sessions

  1. Go to https://platform.openai.com/settings/organization/security (or your account security settings)
  2. Review connected applications and revoke any unfamiliar third-party authorizations
  3. Consider signing out of all sessions and signing back in

Note: OAuth refresh token revocation flows may vary. Check OpenAI’s official security documentation for the most current revocation procedure. If you have billing configured, also review your usage dashboard for any anomalous API calls made with your credentials.

Step 5: Monitor for Unauthorized Usage

Even after revoking tokens, check your OpenAI usage dashboard:

  1. Visit https://platform.openai.com/usage
  2. Look for spikes in usage that don’t match your own workload — especially in the past 30 days
  3. If you see unauthorized charges, contact OpenAI Support immediately and report the incident

How This Attack Worked

According to Aikido Security’s analysis, the codexui-android package established a functional remote UI layer — making it genuinely useful — while inserting a lightweight credential-harvesting routine that activated on every invocation. The stolen tokens were transmitted to an infrastructure disguised as a legitimate error-monitoring endpoint (a spoofed Sentry instance), making outbound traffic look benign to network filters.

The Android variant used a Termux/PRoot Linux environment to run the same underlying npm package locally on Android devices, giving the attack the same reach on mobile as on desktop.

This is a textbook dual-use supply chain attack: build something developers actually want, gain trust and download velocity, then harvest credentials from the entire install base.

How to Stay Safe Going Forward

  • Install OpenClaw only from official sources: https://github.com/openclaw/openclaw or the official website
  • Verify npm package provenance: Check the publisher, repository link, and download history before installing AI-adjacent tooling
  • Use separate API keys per tool: This limits blast radius if any one tool is compromised
  • Regularly audit your OpenAI API key usage: Set usage alerts in the OpenAI dashboard
  • Never install AI tools from APK sites or direct downloads: Stick to the Google Play Store for Android, and verify app publisher identity

The OpenClaw team has not endorsed or published this malicious app or package. If you see references to any “OpenClaw” branded tool outside of official channels, treat it as suspicious until verified.
