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.

The shipped `bin/python` file is not a Python script — it begins with ZIP magic `PK\\x03\\x04` and contains a bundled Windows Python 3.10 distribution (`python310.dll`, `pythonw.exe`, `_ssl.pyd`, `libssl-1_1.dll`, `python310.zip`). After install, invoking `python` from the affected directory resolves to this non-executable archive rather than a real interpreter, breaking the `python` command for anything that resolves it from that directory first. The archive contents are a stock Windows Python runtime and do not contain outbound network code, credential access, or persistence mechanisms; the harm is local breakage of the installer's interpreter command, not exfiltration or remote code execution.\n\nThe package claims to provide a Notepad++ distribution, but in fact delivers ADExplorer, an Active Directory analysis tool.\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\nCampaign: 2026-10-npp-ml\n\nReasons (based on the campaign):\n\n - other\n\n - impersonation","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 npp-ml (PyPI)","id":"MAL-2026-17847","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":"npp-ml","purl":"pkg:pypi/npp-ml","source":"MAL-2026-17847"}],"products":null,"published":"2026-10-12","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-2026-17847/"}
