Which versions of caoxiltts are malicious?

The following PyPI versions of caoxiltts are flagged malicious: 0.1.0, 0.1.1. Treat any of these as compromised.

How do I remediate caoxiltts if I installed it?

caoxiltts 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 caoxiltts — how do I know if it already compromised me?

If caoxiltts 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 caoxiltts part of a known attack campaign?

Yes — caoxiltts is associated with the 2026-10-voxeval, IN-MAL-2026-020901, IN-MAL-2026-020898 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 caoxiltts across my projects, lockfiles, and CI pipelines?

Immediate action

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

pip uninstall caoxiltts

What this malware does

The package advertises itself as a TTS inference helper but harness.run() downloads two gzipped ELF binaries from a configurable host, verifies them against author-pinned SHA256 hashes, writes them to /tmp/.caoxiltts, chmods 0755, and executes them. The 'inference-core' binary is launched with a JSON configuration whose schema (pools[].url/user/pass/keepalive/tls, cpu.threads, mem-locked, cache-budget, autosave) is the XMRig cryptominer configuration shape, not a text-to-speech inference worker. The second binary 'edge-connector' is invoked as access tcp --hostname <edge> --url 127.0.0.1:<port>, matching the Cloudflare Access/cloudflared tunnel CLI shape, exposing a local port outbound through an author-controlled edge. The author-pinned hashes mean the exact bytes executed on the installer's host are chosen by the publisher, and the config/invocation pattern contradicts the package's declared TTS purpose. A supporting _report() helper additionally POSTs run_id, run state, and up to 4000 characters of exception tracebacks (which can carry local path and environment details) to https://<store>/hb on the same host serving the dropped binaries.

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

Detect & block this

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