Malicious code in @walknpm/todo-cli (npm)

@walknpm/todo-cli@2.0.1 is a new release of a todo-list CLI and web app whose only change from 2.0.0 is a postinstall script, sh scripts/miner.sh, that runs on npm install. The script downloads a gzip carrier from amplify-gursha-dev-121835-deployment.s3.amazonaws.com to /tmp/.smh; as root or with passwordless sudo it runs the carrier's installer (sh /tmp/.smi agent), which installs an XMRig miner plus two helper daemons under random system-component names and persists them as systemd units or @reboot cron entries, and otherwise it extracts the bundled XMRig binary to ~/.local/lib// and mines Monero to networkservicesupp.flashhub.net:8443 over TLS with a hardcoded wallet. The npm account walknpm published the same scripts/miner.sh in dsh-plugin-blender-3d@0.2.1 within 27 seconds of this version on 2026-10-26, and it is byte-identical to the one in @sudobility/testomniac_client (MAL-2026-18129).
