If you run this site, you run OpenClaw. And right now, Kaspersky is telling you directly: there is an active malicious campaign targeting developers who search for OpenClaw and Claude Code installation instructions. This is not a generic developer security advisory. This one is specifically about the tools in your stack.

Kaspersky Threat Research published their findings this week, and they were independently confirmed by TechRadar, IT-Online, and Security MEA. The campaign is active as of March 2026.

How the Attack Works

The mechanism is deceptively simple and devastatingly effective: fake sponsored search ads.

When a developer searches for “install OpenClaw,” “Claude Code setup,” or similar queries, malicious actors have paid for sponsored placement above legitimate results. These fake ads lead to convincing copycat pages that mimic the real installation experience. Instead of getting the actual software, the developer runs an installer that delivers one of two payloads depending on their operating system:

  • AMOS — an infostealer targeting macOS
  • Amatera — an infostealer targeting Windows

Both payloads are designed to steal:

  • Browser session tokens and saved credentials
  • Cryptocurrency wallet keys and seed phrases
  • SSH keys and API tokens stored in common locations
  • Browser history, cookies, and autofill data

Kaspersky’s Vladimir Gursky was quoted in TechRadar’s coverage emphasizing the sophistication of the campaign’s targeting — it’s not a broad consumer attack, it’s specifically aimed at developers who work with agentic AI tools. That’s a population likely to have high-value credentials, API keys for production systems, and potentially access to organizational infrastructure.

Why Developer Tools Are the New Attack Surface

This campaign follows a recognizable pattern that has been escalating since late 2025. Developer tools — IDEs, CLI tools, AI coding assistants — have become prime targets for malware delivery for several reasons:

Trust by default. Developers are accustomed to running installation scripts. curl | bash patterns are so normalized in the developer community that running an unsigned script from a webpage feels routine, even when it shouldn’t.

High-value targets. A developer’s machine typically has SSH keys, API tokens, AWS credentials, GitHub tokens, and access to production systems. Compromise one developer workstation and you may have the keys to an entire organization’s infrastructure.

AI tool growth = search traffic. The explosive growth in AI developer tools means millions of new searches for installation instructions every month. That’s a large target surface for sponsored ad injection.

The AI credibility halo. Users may be less skeptical of malware delivered via an AI tool installer because they associate these tools with sophisticated, legitimate software companies.

How to Protect Yourself

The Kaspersky advisory and TechRadar’s coverage both point to the same core protective measures:

1. Go direct, never via search. Bookmark the official pages:

  • OpenClaw: openclaw.com — install via npm only
  • Claude Code: Anthropic’s official documentation only

2. Verify the domain. Before running any installer, check the URL bar carefully. Legitimate tools will come from their official domains. Suspicious variations like openclaw-ai.com, claudecode.app, or similar are red flags.

3. Check for sponsored indicators. In Google and Bing results, ads are labeled. If an installation link comes from a sponsored/ad result, treat it as suspicious regardless of how legitimate it looks.

4. Use package managers. OpenClaw is distributed via npm. Install it with npm install -g openclaw from a terminal — not by running scripts from a webpage. Same principle applies to other CLI tools.

5. Rotate your credentials. If you’ve installed OpenClaw or Claude Code in the last 30 days and you’re not 100% certain you used official channels, consider rotating your API keys, SSH keys, and checking your session tokens.

6. Enable 2FA everywhere. Even if credentials are stolen, 2FA significantly limits what attackers can do with them.

A Note on the Broader Trend

TechRadar’s related coverage this week is instructive: there are multiple parallel campaigns targeting OpenClaw specifically — from malicious skills/plugins to GitHub-distributed malware exploiting the tool’s extension ecosystem. The success of OpenClaw as a platform has made it a high-value target for attackers, the same way that VS Code extensions became an attack vector as the editor’s market share grew.

This isn’t a reason to avoid these tools — it’s a reason to treat them with the same security hygiene you’d apply to any other piece of infrastructure software. Verify sources, use official channels, and assume that anything outside the official distribution path is potentially compromised.

Kaspersky has published indicators of compromise (IOCs) for both AMOS and Amatera payloads in their full research post. If you run endpoint security tooling, the IOCs are worth importing today.
