Update post: We first covered the Hologram infostealer and fake OpenClaw installer campaign on May 8. New reporting from GBHackers and cross-validation across Netskope, SOCPrime, Malwarebytes, Cisco, and the 1Password blog has surfaced additional technical details that expand the picture. This post covers what’s new.

The Hologram infostealer campaign targeting OpenClaw users has more teeth than the initial reports indicated. Multiple independent security researchers have now documented the campaign in detail, and the scope — both in terms of target breadth and infrastructure — is more extensive than the first wave of coverage captured.

Updated Scope: 201 Crypto Wallets, 49 Password Managers

The number that stands out most in the updated research: Hologram is targeting 201 distinct cryptocurrency wallet browser extensions and 49 password managers, including Bitwarden, 1Password, and LastPass.

These aren’t generic targets of opportunity. The wallet extension list represents a carefully curated set of high-value targets — MetaMask, Phantom, Coinbase Wallet, and 198 others that collectively represent where crypto users are most likely to hold accessible balances. The password manager targeting is similarly precise: the focus is on the browser extension variants (rather than desktop apps), which store credentials in ways that are more accessible to browser-based credential harvesting.

The 1Password team has published their own analysis of the campaign, which is worth reading if you use their product — their blog confirms Hologram targets the 1Password browser extension specifically and provides guidance on what the malware accesses versus what it cannot reach in their architecture.

Infrastructure: Azure DevOps C2, Bing-Surfaced Domains

Two infrastructure details from the updated reporting are worth flagging:

C2 servers hosted on Azure DevOps — The command-and-control infrastructure for Hologram is running on Azure DevOps services. This is a meaningful red flag for enterprise security teams: Azure DevOps traffic is frequently whitelisted or given reduced scrutiny in corporate network monitoring configurations because it’s associated with legitimate development tooling. Hologram’s use of Azure DevOps as C2 infrastructure means traditional C2 detection based on suspicious domain patterns or TLD profiling may not catch it.

Fake domains surfacing in Bing search results — Multiple security researchers have confirmed that typosquat and fake download domains for OpenClaw have appeared in Bing organic search results. Users searching for OpenClaw installers through Bing — rather than navigating directly to the official GitHub repository — have encountered fraudulent download pages in search results.

This is an active threat that Bing’s trust and safety team will presumably address, but the window between domain registration, Bing indexing, and takedown represents real exposure. If you found OpenClaw through a search engine recently and installed from a page other than the official GitHub or npm repositories, verify your installation.

How to Verify Your Installation is Legitimate

[See our how-to guide: “How to Verify Your OpenClaw Installation” — coming soon]

The short version:

  • Official source: OpenClaw should be installed via npm install -g openclaw (npm registry) or from the official GitHub repository
  • Do not install from ZIP or 7z archives found on third-party sites, including any file named OpenClaw_x64.7z or similar — this is the known Hologram delivery vector
  • If in doubt: Run your installed binary through VirusTotal and cross-check the hash against the official release hashes published on GitHub

What Hologram Does Once Installed

For readers who missed our original coverage, here’s the attack chain: a fake OpenClaw installer (or archive) appears legitimate, often completing some portion of a fake installation sequence to avoid raising suspicion. Behind the scenes, Hologram — a Rust-based infostealer — executes immediately, harvesting:

  • Cryptocurrency wallet browser extension data from 201 targeted extensions
  • Stored credentials from 49 password manager browser extensions
  • Browser session cookies (enabling account takeover without needing the original password)
  • Local API key files, including .env files that developers commonly store in project directories

Hologram is classified as an infostealer rather than ransomware — it doesn’t encrypt files or demand payment. The credential exfiltration happens silently, and the attacker may not use the harvested credentials immediately, making detection difficult until the damage has already been done.

Enterprise Security Team Considerations

For security teams monitoring corporate developer environments:

  1. Review Azure DevOps egress — Consider whether your network monitoring is appropriately profiling outbound Azure DevOps traffic. Legitimate DevOps pipeline traffic and Hologram C2 traffic both use Azure DevOps infrastructure; the distinction is in the behavioral patterns, not the destination.

  2. Developer workstation scanning — If you have developers in your organization who use OpenClaw, it’s worth verifying their installations are from legitimate sources, particularly if they installed or updated the tool recently.

  3. Browser extension credential exposure — Hologram targets browser extensions specifically. Standard endpoint protection that focuses on the file system or network behavior may miss browser-extension-resident credential stores. Ensure your endpoint tooling covers browser extension data access.

The campaign remains active as of the latest reporting. For the definitive technical indicator list (hashes, domains, IPs), the Netskope and SOCPrime reports linked below are the most comprehensive public sources.
