@wethenorth12/solana-wallet-adapternpm

Advisory published Updated

@wethenorth12/solana-wallet-adapter is a confirmed malicious npm package (MAL-2026-12101) that steals credentials and exfiltrates sensitive data (malicious version 0.18.0). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in @wethenorth12/solana-wallet-adapter (npm)

MAL-2026-12101
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @wethenorth12/solana-wallet-adapter

What this malware does

On require(), index.js JSON-encodes the full process.env plus hostname, username, homedir, platform, cwd, and package metadata, base64-encodes the payload, and sends it as a Telegram Bot API sendMessage GET request to a hardcoded bot token and chat_id (8969499041). A marker file in the OS tmpdir gates the beacon to fire once per host. The package impersonates @solana/wallet-adapter-base: the author field is spoofed as 'anza-xyz', the README advertises a 'drop-in replacement', and the module attempts to require the real @solana/wallet-adapter-base and re-export it so consumers see a working facade while the exfiltration runs silently. Developer and CI environments routinely carry AWS_*, GITHUB_TOKEN, NPM_TOKEN, and other credential-shaped variables, so a full env dump to an attacker endpoint is credential theft against the installer.

Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for @wethenorth12/solana-wallet-adapter (version 0.18.0).

  2. If you installed it — respond

    @wethenorth12/solana-wallet-adapter 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.

  3. Did it already run?

    If @wethenorth12/solana-wallet-adapter 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.

Frequently asked questions

No. @wethenorth12/solana-wallet-adapter on npm has been identified as a malicious package (version 0.18.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
