I was working on setting up my development environment for Ethereum smart contracts using VS Code. After running into some installation issues, I decided to get help from an AI assistant. The assistant kept suggesting I reinstall the framework, so I copied and pasted the commands without paying close attention.
On my third attempt, I executed this command:
npm install -g ethereum-dev-tools32
But I realized later it should have been:
npm install -g truffle
The package name looked strange with those extra characters and numbers. When I checked with another AI tool, it warned me this could potentially be a malicious package.
I normally double-check commands before running them, but it was late at night and I was tired. Fortunately, I was working inside a VM environment running Windows 11, so hopefully any damage would be contained. Has anyone else encountered similar fake packages? What should I do next to check if my system is compromised?
The Problem: You accidentally installed a malicious npm package (ethereum-dev-tools32) instead of the intended package (truffle) while setting up your Ethereum smart contract development environment. You are concerned about potential system compromise.
TL;DR: The Quick Fix:
Uninstall the malicious package: Open your terminal and run: bash npm uninstall -g ethereum-dev-tools32
Scan for malware (optional but recommended): Run a full system scan with your preferred antivirus software.
Understanding the “Why” (The Root Cause):
This happened because of typosquatting, a common attack where malicious actors create npm packages with names very similar to legitimate ones. The attacker hopes developers will make a typo and accidentally install their malicious package. The extra “32” in ethereum-dev-tools32 is a classic example of this technique. These packages can contain malware that steals credentials, private keys, or performs other harmful actions. Your use of a Windows 11 VM significantly reduces the risk, as the damage would likely be contained to that virtual machine. However, it’s still crucial to take steps to mitigate any potential threat.
Step-by-Step Guide:
Uninstall the malicious package: Open your terminal or command prompt and execute the following command: bash npm uninstall -g ethereum-dev-tools32 . This removes the potentially harmful package from your global npm installation.
Verify the removal: After uninstalling, check if the package is still present by running: bash npm list -g | grep ethereum-dev-tools32 . If it’s listed, repeat step 1.
Install the correct package: Now, install the legitimate truffle package using the correct command: bash npm install -g truffle .
Run a malware scan: While the VM provides isolation, it’s crucial to perform a full system scan within the VM to detect and remove any files or processes that the malicious package may have installed. Use your preferred antivirus software.
Check for unusual processes: Examine your running processes (Task Manager in Windows) and look for any unfamiliar or suspicious processes. If you identify anything out of the ordinary, research it to determine if it’s related to the malicious package.
Review system logs (advanced): If you’re comfortable with system logs, examine them for any unusual activity that may have occurred around the time you installed the malicious package. This is an advanced step but can provide valuable insights.
Common Pitfalls & What to Check Next:
Transitive Dependencies: Even if ethereum-dev-tools32 is removed, check if it installed any other suspicious packages as dependencies. Use npm ls to list all installed packages, including transitive dependencies, and check if any look out of place.
Global vs. Local Packages: Ensure that you’re installing packages correctly in your project environment, rather than globally, where possible. Installing packages locally using npm install truffle (without the -g) will confine the packages to the current project and limit potential damage if a malicious package is encountered.
Regular Security Updates: Keep your operating system and npm updated to benefit from the latest security patches.
Future Prevention: Implement a rigorous process for verifying the legitimacy of npm packages before installation. This should involve checking the package details on the official npm registry, confirming its download count, and examining the maintainer’s reputation. Consider using tools that help identify and flag malicious packages.

yikes, that package name looks sketchy with those random numbers. you’re in a VM tho, so you should be mostly safe. I’d check what files got created - malicious packages often drop stuff in weird places. also run npm audit in case it pulled in other sketchy dependencies. worst case, just nuke the VM and start fresh.
This exact thing happened to me six months ago with a different package. The fatigue factor is real - I was debugging deployment issues until 3am and fell for a similar trap with a fake hardhat variant. Since you’re in a VM, you can be thorough. Take a snapshot of your current VM state first before doing anything destructive. Then check what the package actually did - look at the installation directory and any post-install scripts it ran. One thing others haven’t mentioned - check your browser saved passwords and any crypto wallets you accessed in that VM. Even if the package seemed harmless, some malicious npm packages specifically target developer environments to steal credentials or private keys. The VM isolation was smart, but also make sure it didn’t establish persistent connections or modify system configs. I learned this the hard way when a sketchy package modified my hosts file to redirect certain domains. For future reference, legitimate Ethereum development packages are usually published by verified organizations on npm. The official Truffle suite packages have clear ownership and extensive documentation. When in doubt, always cross-reference with the project’s official GitHub repository.
Been dealing with blockchain dev for years - typosquatting happens all the time in this space. That “32” in the package name is a dead giveaway. Attackers love using numbered variants of legit packages. Since you caught it fast, you’re probably fine. But don’t just uninstall - run npm cache clean --force and check your global packages too. Malicious stuff sometimes messes with other installed tools. Good call on the VM. Also check if it created any weird configs or changed your npm settings. Look at your .npmrc file and global node_modules for anything sketchy. For next time: always verify package names on the official npm registry first, especially for dev tools. Real Truffle has millions of downloads. Fake packages usually have barely any downloads and were just published.
Good thing you used a VM. That package name with random numbers? Classic typosquatting move.
Don’t check this stuff manually - set up monitoring instead. Mine watches npm installs in real time, cross-checks package names against official registries, and flags sketchy stuff.
It also checks download counts, publication dates, and maintainer info before packages hit my system. Anything suspicious gets blocked and I get an alert with the details.
Your VM idea’s smart, but you can do better. I auto-provision clean dev environments with pre-approved package lists. No more 3am typo disasters.
For now, check your npm global config and any environment variables that changed. Malicious packages often mess with PATH or drop persistent scripts.
Just automate the whole verification process and never worry about it again.
