# MAL-2026-12094: Malicious code in @wethenorth12/ethers-wallet (npm)


- **Type:** Malicious package
- **Package:** `@wethenorth12/ethers-wallet` (npm)
- **Published:** 5 Aug 2026

## What is MAL-2026-12094?

MAL-2026-12094 is a malicious package in @wethenorth12/ethers-wallet, published on 5 Aug 2026. 

### Official description

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.

## What should I do about MAL-2026-12094?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
