Source: amazon-inspector (23b18de964968b1d4f9333a1bcc5f247b3978f9fdc418f01f7e9a3c7bc578a62)

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:///hb on the same host serving the dropped binaries.

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

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
