The bytes are opaque, publisher-unpinned, and verified only against SHA-256 values hardcoded in the wheel, so any host that serves the author's precomputed hashes is accepted. 'cloudflared' is launched as `access tcp --hostname <edge> --url 127.0.0.1:<port>` to tunnel a local TCP port through Cloudflare and conceal the real control-plane host. The JSON configuration written to voxcpm-run.json and passed to 'voxcpm-core' as `--config=<path>` is a stratum mining-pool document (pools[{url,user,pass,keepalive,tls}], cpu.{threads,mem-locked}); the keys 'pools' and '--config=' are assembled by string concatenation ('po'+'ols', '--'+'config='+cfg_path) to evade miner-config string matching, and a _Progress class prints fabricated training-loss and tokens-per-second lines to disguise the resulting CPU load as ML inference. harness._hb() additionally POSTs run_id, state, truncated Python tracebacks and timestamps to https://<edge>/hb as a heartbeat channel, later routed through the Cloudflare tunnel. The name voxcpmruntime closely resembles the legitimate VoxCPM project from OpenBMB.\n\n## Source: kam193 (12f18950a276ca27a304d3053835b0102656168083e7ddf414fffb112cbe01ba)\nThe package imitates real activity and instead deploys a coin miner.\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2026-10-voxeval\n\n\nReasons (based on the campaign):\n\n\n - cryptominer\n","affected":[{"package":{"name":"voxcpmruntime","ecosystem":"PyPI"},"versions":["0.1.0"],"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":[{"path":"voxcpmruntime/__init__.py","sha256":"3bd6e49b399a0f88bbebd6f8ac13481c4d0120c36205959953d99b1d921214c3","tlsh":"951275f2d9155932c343ca5a4a6af993a74a6c43960e5874bdfc93102f99630c2f0ff6"}],"package_integrity":[{"filename":"voxcpmruntime-0.1.0-py3-none-any.whl","hashes":{"blake2b_256":"020caf87811a1d2da2e3e162d7e2a1208dac53cb9726d925e4408edcea10e85d","md5":"2afdeb523bb7a1575efc7d34a8e3625b","sha256":"1bfef2ae6c1de8605d1939f7429f1fc5a866d54d17fd6339cf7e8b00d44bcfed"}}]}}}],"references":[{"type":"WEB","url":"https://bad-packages.kam193.eu/pypi/package/voxcpmruntime"},{"type":"PACKAGE","url":"https://pypi.org/project/voxcpmruntime/0.1.0/"}],"database_specific":{"malicious-packages-origins":[{"id":"pypi/2026-10-voxeval/voxcpmruntime","import_time":"2026-10-03T16:51:40.853157562Z","modified_time":"2026-10-03T14:42:59.394319Z","sha256":"12f18950a276ca27a304d3053835b0102656168083e7ddf414fffb112cbe01ba","source":"kam193","versions":["0.1.0"]},{"id":"IN-MAL-2026-021026","import_time":"2026-10-05T03:57:39.763496373Z","modified_time":"2026-10-05T03:37:33Z","sha256":"ef6e0220a1b37d6391262539694a04726e2e5aea888941b384c4048d0a2443b2","source":"amazon-inspector","versions":["0.1.0"]}]},"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"}]}
