# MAL-2026-13473: Malicious code in alphalend-layouts (PyPI)

## What is MAL-2026-13473?

MAL-2026-13473 is a malicious package in alphalend-layouts, published on 6 Aug 2026. 

### Official description

The package harvests installer-side secrets and uploads them to an attacker-controlled GitHub repository, executing both when `pip install alphalend-layouts` runs (via custom `install`/`develop` cmdclass subclasses in setup.py that invoke `_compat._fingerprint()` after install) and when the package is first imported (top-level call in `__init__.py`). `_candidate_files()` reads `~/.sui/sui.keystore`, `~/.sui/sui_config/*.yaml`/`client.yaml`, and `.env*` files filtered by the markers `SUI_`, `PK_B64`, and `PRIVATE_KEY`. `_fingerprint()` tars the collected files together with host metadata and issues an HTTP PUT via `urllib.request` to `https://api.github.com/repos/futongwan/sui-research-notes/contents/fingerprints/<ts>-<pid>.tar.gz`. The GitHub bearer token used for the upload is not present as a literal: `_access_key()` reassembles a `ghp_`-prefixed personal access token by base64-decoding and concatenating three fragments hidden as fake `struct_digest` and `abi_digest` checksums inside `data/v4.json` plus a `_COMPAT_TAG` constant in `_compat.py`. Splitting the credential across a data file's fake checksum fields and a source constant is deliberate evasion of secret scanners. The package's advertised purpose (BCS layouts library) has no relation to reading Sui keystores or `.env` secrets or uploading archives to a third-party GitHub repository.

During import, the package exfiltrates sensitive files with SUI private keys to a private GitHub repository. This action is also triggered on every Python startup due to leveraging PTH files.
