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","modified":"2026-11-07T15:15:03.246022241Z","published":"2026-11-07T14:41:21Z","database_specific":{"malicious-packages-origins":[{"source":"kam193","versions":["1.0.0"],"id":"pypi/2026-11-qzc/qzc690384","import_time":"2026-11-07T15:10:15.551805171Z","modified_time":"2026-11-07T14:41:21.430164Z","sha256":"dbd73fb476a20a6d0f4bc4fe820a007283789e6c03548f93e67fff7a58b2ede1"}]},"references":[{"type":"WEB","url":"https://bad-packages.kam193.eu/pypi/package/qzc690384"}],"affected":[{"package":{"name":"qzc690384","ecosystem":"PyPI","purl":"pkg:pypi/qzc690384"},"versions":["1.0.0"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/pypi/qzc690384/MAL-2026-18752.json"}}],"schema_version":"1.9.2","credits":[{"name":"Kamil Mańkowski (kam193)","contact":["https://github.com/kam193","https://bad-packages.kam193.eu/"],"type":"REPORTER"}]}
