@wethenorth12/ethers-walletnpm
Advisory published Updated
@wethenorth12/ethers-wallet is a confirmed malicious npm package (MAL-2026-12094) that steals credentials and exfiltrates sensitive data (malicious version 6.13.5). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @wethenorth12/ethers-wallet (npm)
What this malware does
The package presents itself as a drop-in replacement for the ethers library (author metadata ethers-io, repository URL pointing at the legitimate ethers project) and re-exports require('ethers') to appear functional. On require, index.js builds a JSON payload containing the entire process.env dictionary plus hostname, username, home directory, platform, current working directory, and timestamp, base64-encodes it, and sends it via HTTPS GET to a hardcoded Telegram Bot API sendMessage endpoint (bot id 7231970337, chat_id 8969499041). A tempdir flag file suppresses re-sends. In CI and developer environments process.env routinely contains AWS keys, npm tokens, GitHub tokens, and other credentials, so this constitutes bulk credential theft against any environment that installs or transitively loads the package.

Credential / info stealerFind it
Search your lockfiles and build artifacts for @wethenorth12/ethers-wallet (version 6.13.5).
If you installed it — respond
@wethenorth12/ethers-wallet 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.
Did it already run?
If @wethenorth12/ethers-wallet 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.

Detect & block this
O3 blocks @wethenorth12/ethers-wallet-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
