The collected fingerprint is base64-encoded and smuggled as 40-character-chunk model names into POST requests to a local Xinference server at http://127.0.0.1:9997/v1/model_registrations/flexible, using `xinference.model.flexible.launchers.transformers_launcher` as the launcher reference, so an operator with access to that Xinference instance can retrieve the host fingerprint by listing registered models. The build-command guard only skips metadata-only invocations, so the reconnaissance fires on a plain install. The package ships no real library functionality — the install-time code is the entire payload.\n\n## Source: kam193 (50064433aa6b4768163042513bbee6b92d28a48804f5e564ac3532354af7d422)\nIn this campaign, packages execute malicious code during installation. The exact behavior varies between versions: fingerprinting environment, exposing a backdoor server listening for remote commands, downloading remote commands from a hardcoded location. Next stages seem to be downloaded from localhost, what suggests the code may still be a preparation for the real attack.\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2026-11-qzc\n\n\nReasons (based on the campaign):\n\n\n - The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.\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 - backdoor\n\n\n - The package overrides the install command in setup.py to execute malicious code during installation.\n","affected":[{"package":{"name":"qzc690383","ecosystem":"PyPI"},"versions":["1.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"artifacts":["qzc690383-1.0.0.tar.gz"],"path":"setup.py","sha256":"1d626adb1937659b2e35a3df7c31094f1776cbdc13743ff5a42fac236d1b1d43","tlsh":"b4515545d8365963b3cb58e4248a8433a3569f1b8a117c24ba9c4b7c1f8c07ce7b35b6"}],"package_integrity":[{"filename":"qzc690383-1.0.0.tar.gz","hashes":{"blake2b_256":"740d96b5f5dcb54a4563b6ef19cb7ae15d4d55c5b386e882e4d251d7e39f6f67","md5":"0eae3b6ac2446c9faffcc1b9ae4de08a","sha256":"46a8c7685d1be13a0d6e7ee145a972e39b77299ecb205fa20d975324beb951bf"}}]}}}],"references":[{"type":"PACKAGE","url":"https://pypi.org/project/qzc690383/1.0.0/"},{"type":"WEB","url":"https://bad-packages.kam193.eu/pypi/package/qzc690383"}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-022546","import_time":"2026-11-07T10:36:42.73214866Z","modified_time":"2026-11-07T10:21:28Z","sha256":"d4b997b7e9404963bfb44f2179abe28dd5238feac452fcce4b77fc945c430c06","source":"amazon-inspector","versions":["1.0.0"]},{"id":"pypi/2026-11-qzc/qzc690383","import_time":"2026-11-07T15:10:15.551053637Z","modified_time":"2026-11-07T14:51:07.964916Z","sha256":"50064433aa6b4768163042513bbee6b92d28a48804f5e564ac3532354af7d422","source":"kam193","versions":["1.0.0"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"Kamil Mańkowski (kam193)","contact":["https://github.com/kam193","https://bad-packages.kam193.eu/"],"type":"REPORTER"}]}
