Two separate but thematically linked malware campaigns went live this week, both targeting the same population: developers and practitioners who are actively searching for and installing AI tools. One impersonates OpenClaw. One impersonates Claude. Both are dangerous. And both are live right now.

Campaign 1: Hologram Infostealer — Fake OpenClaw Installer

Security researchers at CybersecurityNews identified an active distribution campaign deploying the “Hologram” infostealer through a counterfeit OpenClaw installer package.

The attack chain is classic drive-by malware with an AI-era twist:

  • Threat actors register typosquat domains or clone official-looking download pages for OpenClaw
  • Victims searching for OpenClaw installation packages — particularly those arriving via search engines rather than bookmarked official links — may land on the fake site
  • The downloaded “installer” executes Hologram, which immediately begins scanning for and exfiltrating:
    • 250+ cryptocurrency wallet browser extensions (MetaMask, Phantom, Coinbase Wallet, and many others)
    • Password manager vaults and stored credentials
    • Browser session cookies that can be used for account takeover without needing the original password
    • Local API key files, including .env files in developer directories

Hologram is classified as an infostealer rather than ransomware — it doesn’t encrypt your files or demand payment. Instead, it silently harvests credentials and transmits them to attacker-controlled infrastructure, often while appearing to install nothing or completing a fake installation sequence to avoid suspicion.

Campaign 2: Beagle RAT — Fake Claude Website

Independently, Sophos researchers discovered a second active campaign distributing a backdoor Remote Access Trojan dubbed “Beagle” through a fraudulent Claude website. The campaign was picked up by TechRadar and ITPro based on the Sophos research.

The Beagle campaign uses DLL sideloading — a more technically sophisticated technique where a legitimate-looking application loads a malicious DLL file from the same directory, exploiting Windows’ DLL search order to execute attacker code while appearing to run normal software.

The fake Claude “website” presents as a developer-focused download portal, targeting AI practitioners who might download a local inference client, developer tool, or API testing utility branded as Claude. Once the malicious installer runs:

  1. A legitimate-looking application starts up (providing cover)
  2. Beagle’s DLL is sideloaded into the process
  3. Beagle establishes persistent remote access, giving attackers full control over the victim’s machine
  4. As a backdoor RAT, Beagle enables lateral movement, data theft, further malware deployment, or use of the compromised machine as a pivot point

RATs are significantly more dangerous than infostealers because the attacker maintains ongoing interactive access rather than a one-time data grab. If Beagle establishes persistence on a developer workstation with access to production infrastructure, the blast radius is substantial.

Why AI Tool Impersonation Is So Effective Right Now

Both campaigns exploit the same fundamental dynamic: demand for AI tools is outpacing users’ ability to verify what they’re installing.

When OpenClaw releases a new version, or when Claude announces a new feature, there’s an immediate spike in searches from users who want to install or try the new capability. Attackers monitor these announcement cycles and spin up fake pages timed to capture that traffic.

The AI developer community is also somewhat more trusting than average users might be — there’s a cultural assumption that technical users are sophisticated enough to avoid obvious malware traps. But these campaigns are designed specifically to fool developers: they use correct branding, plausible download flows, and occasionally even functioning software alongside the malicious payload.

How to Protect Yourself: A Practical Verification Checklist

Before installing any AI tool:

  1. Start from the official source. For OpenClaw: openclaw.com. For Claude: claude.ai and anthropic.com. Never start from a search result — bookmark official pages and navigate there directly.

  2. Verify the domain exactly. Typosquat domains often look nearly identical at a glance: opencl4w.com, openclav.com, c1aude.ai. Check the address bar carefully before downloading.

  3. Check the SSL certificate. Click the padlock in your browser and verify the certificate was issued to the legitimate organization, not just that it has HTTPS (which is trivially easy to fake).

  4. On macOS, verify the code signature before installing any downloaded application: codesign -dv --verbose=4 /path/to/downloaded.app. Legitimate software from major vendors will be properly signed.

  5. On Windows, check the digital signature in the file’s Properties → Digital Signatures tab before running any installer.

  6. Use VirusTotal. Drop any downloaded installer at virustotal.com before running it. Not foolproof, but catches most known threats.

  7. Watch for unexpected network activity immediately after installing anything. Tools like Little Snitch (macOS), GlassWire (Windows), or netstat can reveal immediate exfiltration attempts.

  8. Never install AI tools on machines with direct access to production credentials or databases if you can help it. Use isolated developer machines or VMs for experimentation with new tools.

Both Campaigns Are Active Now

Neither the Hologram nor Beagle campaigns have been confirmed as taken down as of this writing. Assume both are live and actively catching victims.

If you installed something recently that you can’t fully verify, treat it as potentially compromised: rotate your API keys and passwords, revoke active sessions, and consider re-imaging the machine if you have reason to be concerned.
