Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-13473/ (Markdown: https://insights.sbomify.com/MAL-2026-13473/index.md)","id":"MAL-2026-13473","markdown":"https://insights.sbomify.com/MAL-2026-13473/index.md","name":"MAL-2026-13473","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"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/\u003cts\u003e-\u003cpid\u003e.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.\n\nDuring 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.\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\nCampaign: 2026-08-alphalend-layouts\n\nReasons (based on the campaign):\n\n - files-exfiltration\n\n - obfuscation\n\n - crypto-related\n\n - exfiltration-crypto\n\n - abuses-pth","ecosystems":["PyPI"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in alphalend-layouts (PyPI)","id":"MAL-2026-13473","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"PyPI","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":[],"last_affected":[],"package":"alphalend-layouts","purl":"pkg:pypi/alphalend-layouts","source":"MAL-2026-13473"}],"products":null,"published":"2026-08-06","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-13473/"}
