# MAL-2026-10197: Malicious code in metemask-sdk (PyPI)


- **Type:** Malicious package

## What is MAL-2026-10197?

MAL-2026-10197 is a malicious package in metemask-sdk, published on 12 Jul 2026. 

### Official description

metemask-sdk is a typosquat of the legitimate metamask-sdk package. On import, the top-level __init__.py performs an outbound HTTP fetch to https://gateway.pinata.cloud/ipfs/QmWMbuhKt24ssRKXCeiU94NoZGYcEunGnm6uvSKRwkejYP, passes the response body to exec(), and then invokes a main() function from the executed namespace. No integrity check (hash/signature) is performed on the fetched content, the fetch is wrapped in a bare try/except to suppress errors, and the IPFS CID resolves to attacker-controlled content that can change arbitrarily. The package's advertised public API (connect, sign_message, get_balance) is a non-functional stub that returns constants and random bytes, serving as a facade for the import-time dropper.

During import, the code downloads and executes a remote script. The script collects sensitive files, including cryptocurrency wallet private keys and seeds, SSH keys, dotenv files and uploads them to IPFS. After that, it communicates with C2 and awaits further commands to execute.
