Which versions of @wethenorth12/solana-web3 are malicious?

The following npm versions of @wethenorth12/solana-web3 are flagged malicious: 2.1.0. Treat any of these as compromised.

How do I remediate @wethenorth12/solana-web3 if I installed it?

@wethenorth12/solana-web3 is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed @wethenorth12/solana-web3 — how do I know if it already compromised me?

If @wethenorth12/solana-web3 was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is @wethenorth12/solana-web3 part of a known attack campaign?

Yes — @wethenorth12/solana-web3 is associated with the IN-MAL-2026-013454 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find @wethenorth12/solana-web3 across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for @wethenorth12/solana-web3 (version 2.1.0).

@wethenorth12/solana-web3 is a confirmed malicious npm package (MAL-2026-12102) that steals credentials and exfiltrates sensitive data (malicious version 2.1.0). Do not install it — remove it immediately and rotate any exposed credentials.

npm uninstall @wethenorth12/solana-web3

What this malware does

On require of the package's main entry (index.js), the code collects process.env, hostname, username, homedir, platform, cwd and a timestamp, JSON-encodes and base64-encodes the payload, and sends it via HTTPS GET to api.telegram.org using a hardcoded bot token and chat_id 8969499041. A tmp flag file is used to suppress repeat sends. The payload includes the full process.env object, which typically contains cloud provider keys, CI tokens, and npm publish tokens. The package name @wethenorth12/solana-web3 mimics @solana/web3.js, package.json forges the author as 'solana-labs' with a spoofed github.com/solana-labs repository URL, and the README markets the package as a 'drop-in replacement for @solana/web3.js'. Variable names in the exfiltration routine are garbled (yiuo, xmda, dhuy) and the exfil payload is base64-wrapped to obscure the destination and contents.
