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.

Versions 0.1.0 and 2.0.0 do this directly during import; version 2.0.1 starts a daemon thread during import to perform the same action. The package's CLI and GUI entry points import this module. The remote file's Git history contains a Windows remote file management client that registers persistence through an HKCU Run entry, polls `https://googleforum.pythonanywhere.com` for commands, and supports file upload, download, deletion, and command execution. An earlier remote-file revision is byte-identical to the `readme.txt` payload reported in MAL-2026-17752 (`agentaix`); the 39,931-byte `agentaix/gui.py` is also byte-identical across that package and all py-worm releases. The remote file is mutable; its contents at the time of any particular victim import and actual execution on victim systems have not been established.\n\nThe package name 'py-worm' is suggestive of self-propagation behavior, but no a static rule fired and no traced code behavior was captured for this version. Without concrete evidence of credential harvest, outbound exfiltration, install-time code execution, or publish-token enumeration in the shipped files, the package cannot be classified as a confirmed supply-chain attack from the available signals alone.\n\nThe package installs a persistent job that allows the attacker for exfiltrating files and executing remote code on the victim's machine.\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\nCampaign: 2026-10-agentaix\n\nReasons (based on the campaign):\n\n - files-exfiltration\n\n - peristence-autorun\n\n - The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.\n\n - rat\n\n - persistence\n\n - Downloads and executes a remote malicious script.","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 py-worm (PyPI)","id":"MAL-2026-17883","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":"py-worm","purl":"pkg:pypi/py-worm","source":"MAL-2026-17883"}],"products":null,"published":"2026-10-15","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-2026-17883/"}
