Which versions of voxcpmruntime are malicious?

The following PyPI versions of voxcpmruntime are flagged malicious: 0.1.0. Treat any of these as compromised.

How do I remediate voxcpmruntime if I installed it?

voxcpmruntime is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed voxcpmruntime — how do I know if it already compromised me?

If voxcpmruntime was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is voxcpmruntime part of a known attack campaign?

Yes — voxcpmruntime is associated with the 2026-10-voxeval, IN-MAL-2026-021026 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find voxcpmruntime across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for voxcpmruntime (version 0.1.0).

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

pip uninstall voxcpmruntime

What this malware does

The package presents itself as a VoxCPM TTS runtime but is a binary dropper and cryptominer loader. harness.run() downloads two executables ('voxcpm-core' and 'cloudflared') from a caller-supplied edge host at https://<edge>/files/<name>, writes them under /tmp/.voxcpm-runtime/, chmods them 0o755, and spawns them. 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.

The package imitates real activity and instead deploys a coin miner.

Detect & block this

O3 blocks voxcpmruntime-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
