A second bundled binary, voxcpmtts3/bin/cloudflared (~40MB), is launched with 'access tcp --hostname <edge> --url 127.0.0.1:<port>' to open a raw TCP tunnel through Cloudflare Access, hiding the real mining pool address behind a Cloudflare Access hostname and defeating destination-based blocking; a code comment acknowledges the design is to keep the traffic readable at the Cloudflare front door. In parallel, self._hb() POSTs run_id, state, Python tracebacks (up to 4000 chars) and timestamps to https://<edge>/hb through the same attacker-controlled Cloudflare Access hostname, giving the operator a per-victim telemetry channel that also leaks local filesystem paths from error traces. The 'TTS inference', 'coordinator', and 'step/loss/tok/s' terminology in code and README is cover for stratum mining pool concepts.\n\n## Source: kam193 (382411a9cc0ee358dbd8efcf17c5a943fc496fc4f2c86ffdc8f87d7efc43ec2d)\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\n\n## Affected packages\n\n- `voxcpmtts3`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"abyssal","depthScore":70,"depthScoreParts":{"impact":52.3,"likelihood":0,"exploitation":18,"ransomware":0},"changes":[]}
