When a consumer calls Coordinator.create_runner(config), the package writes rvs.sh alongside entry.sh/runner.sh/setup_pty/gdrive_setup into a kernel folder; Coordinator.run_local() then executes `python main.py`, which invokes `bash -x entry.sh`, which in turn backgrounds rvs.sh — opening an interactive shell from the runner's host back to the author-controlled duckdns.org subdomain. The same bundle wgets a gdrive binary from github.com/gdrive-org/gdrive/releases/download/2.1.0/gdrive-linux-x64 and installs it to /bin/gdrive. None of this behavior is documented in the README (which advertises AMQP logging for Kaggle kernels). The reverse shell does not fire at import/install time — setup.py and __init__.py are clean — but it fires as part of the package's advertised Coordinator API flow, so any consumer who actually uses the library exposes the executing host (their machine or a Kaggle kernel they push) to the author. A separate file (kaggle_runner/utils/utils.py) also hardcodes CloudAMQP credentials (termite.rmq.cloudamqp.com / drdsfaew) with a comment 'oh~ just give my password out~' — this is author self-harm and on its own would be allow, but combined with the reverse-shell pipe to a duckdns C2 host, the installer-side impact is clear.\n","affected":[{"package":{"ecosystem":"PyPI","name":"kaggle-runner"},"versions":["0.0.2"],"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":[{"path":"kaggle_runner/coordinator.py","sha256":"c1f7a17586b660e76fef8aad913582151c1543b9a16295827c1d6959010b239b","tlsh":"99820703846a1b30a7d35898944793a82b95ec6717626c1272fcb3606f25378d1fb3fa"},{"path":"kaggle_runner/utils/utils.py","sha256":"1e839d5791497cdec65ec2bb39c9e020455f4ec2b00da39097a51d9d0831c1eb","tlsh":"ba216a516317d84c20aa62525c26762178b8d50b8908f87836bd93042f1fcaec5f5da5"}],"package_integrity":[{"filename":"kaggle_runner-0.0.2-py3-none-any.whl","hashes":{"blake2b_256":"dee805394b0645cb915b45b17db2962095e52d7e1b19acada5e309a1c3df73b0","md5":"1f7a609aae6cbe3e9fb95f9f97f1cad4","sha256":"1933f25867446dbf3841aa0f5ae17d3c2531c2ccb0756bd7837a2e03c1101282"}},{"filename":"kaggle_runner-0.0.2.tar.gz","hashes":{"blake2b_256":"92631de2a6f61f5337c9f69a5bd970c830fc956a735ac83e254581b67605ed18","md5":"1128e0a6ade04d902944d6430b145995","sha256":"a16105cc549bd500e214298b237b6ac1c1c123ff2f7de59f364249c753a70a67"}}]}}}],"references":[{"type":"PACKAGE","url":"https://pypi.org/project/kaggle-runner/0.0.2/"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["actran@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-002524","import_time":"2026-05-13T20:10:59.625163518Z","modified_time":"2026-05-12T19:03:07Z","sha256":"8dcd49ca70b987b236ba4341d839addfec9afb344e1471195f2f825281092f71","source":"amazon-inspector","versions":["0.0.2"]}]}}
