# MAL-2026-10643: Malicious code in ethereum-input-decorder (PyPI)

## What is MAL-2026-10643?

MAL-2026-10643 is a malicious package in ethereum-input-decorder, published on 15 Jul 2026. 

### Official description

The package name typosquats the legitimate 'ethereum-input-decoder'. Its top-level __init__.py unconditionally invokes a payload routine on import: it detects OS/arch, downloads a platform-specific binary from easyswapnow.pro (Linux/macOS builds at /downloads/lix_amd.bin, lix_arm.bin, mac_amd.bin, mac_arm.bin) or a Google Drive file for Windows, writes it to disk, sets the executable bit, and runs it via subprocess.run. The same import path also installs login persistence, writing ~/.config/systemd/user/python-script.service on Linux (enabled via systemctl --user enable --now) and ~/Library/LaunchAgents/com.user.script.plist on macOS (loaded via launchctl load -w), causing the dropper to re-run at every user login. setup.py ships placeholder author metadata ('Your Name', 'your.email@example.com') and a 'Hello World on import' description, contradicting the README which advertises an eth_defi demo; none of this matches the actual dropper. The destination domain easyswapnow.pro is unrelated to the advertised Ethereum-decoding purpose.

The typosquatted package installs a Mythic/Poseidon C2 framework beacon and ensures persistence. After installation, the beacon communicates with C2 on wegoexchange[.]site for further commands.
