{"schema_version":"1.7.4","id":"MAL-2026-17883","published":"2026-10-15T08:29:24Z","modified":"2026-10-29T14:16:01.358508011Z","summary":"Malicious code in py-worm (PyPI)","details":"Importing py-worm's `agentaix` module downloads a mutable Python file from `https://raw.githubusercontent.com/anonrider404/pypl/refs/heads/main/readme.txt` to a temporary `.py` file and launches it without a visible console on Windows. 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\n---\n_-= Per source details.

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\n## Source: kam193 (d4c5838f30da7c1f684305ec0704ef37e963793449390f5b13a4e06212ccbd9d)\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---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2026-10-agentaix\n\n\nReasons (based on the campaign):\n\n\n - files-exfiltration\n\n\n - peristence-autorun\n\n\n - The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.\n\n\n - rat\n\n\n - persistence\n\n\n - Downloads and executes a remote malicious script.\n","affected":[{"package":{"name":"py-worm","ecosystem":"PyPI"},"versions":["0.1.0","2.0.0","2.0.1"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"package_integrity":[{"filename":"py_worm-2.0.0-py3-none-any.whl","hashes":{"blake2b_256":"176f0efd0b9c049435a2f610272b7630d451621ba6676ae66afe3e719a158476","md5":"452882a3c6d531240df37d6c5ec8aea5","sha256":"426d98c8403c066a955575c414f0941042c31dd11791fe73a0db68a09f644029"}},{"filename":"py_worm-2.0.0.tar.gz","hashes":{"blake2b_256":"3206949afef96592fbf7d9bd45cae614803adf907b31dbb2c36c043a2404fe8a","md5":"3f94d0bb739a9be48ffdb7e436921f4b","sha256":"cace83399e5a2523a88be4e07a1fd211def3f2f9e5040693539ff1356806aa02"}}]}}}],"references":[{"type":"WEB","url":"https://bad-packages.kam193.eu/pypi/package/py-worm"},{"type":"EVIDENCE","url":"https://files.pythonhosted.org/packages/59/de/799235425a54e0fd7ca9ac5306dd21675b390b1c0241caa1115f1371eb95/py_worm-2.0.1-py3-none-any.whl"},{"type":"WEB","url":"https://github.com/anonrider404/pypl/blob/9395c5802b11bc088925d7adf6e2f66b8b0709fd/readme.txt"},{"type":"ADVISORY","url":"https://osv.dev/vulnerability/MAL-2026-17752"},{"type":"PACKAGE","url":"https://pypi.org/project/py-worm/2.0.0/"}],"database_specific":{"iocs":{"domains":["googleforum.pythonanywhere.com"],"urls":["https://raw.githubusercontent.com/anonrider404/pypl/9395c5802b11bc088925d7adf6e2f66b8b0709fd/readme.txt","https://raw.githubusercontent.com/anonrider404/pypl/refs/heads/main/readme.txt","https://github.com/anonrider404/pypl"]},"malicious-packages-origins":[{"id":"pypi/2026-10-agentaix/py-worm","import_time":"2026-10-15T09:20:03.534680188Z","modified_time":"2026-10-15T08:29:24.603564Z","sha256":"d4c5838f30da7c1f684305ec0704ef37e963793449390f5b13a4e06212ccbd9d","source":"kam193","versions":["0.1.0","2.0.0","2.0.1"]},{"id":"IN-MAL-2026-022052","import_time":"2026-10-29T14:14:21.283339964Z","modified_time":"2026-10-29T13:42:33Z","sha256":"8fd8563e18894311d651012477647efc1a169f465a9cf89db5e7245b0b6ffcc9","source":"amazon-inspector","versions":["2.0.0"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"ESTsecurity","contact":["https://www.estsecurity.com/"],"type":"FINDER"},{"name":"Kamil Mańkowski (kam193)","contact":["https://github.com/kam193","https://bad-packages.kam193.eu/"],"type":"REPORTER"}]}
