Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-3757/ (Markdown: https://insights.sbomify.com/MAL-2026-3757/index.md)","id":"MAL-2026-3757","markdown":"https://insights.sbomify.com/MAL-2026-3757/index.md","name":"MAL-2026-3757","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On `npm install -g`, the package's `scripts/post-install.js` registers a privileged Windows service `claw-subagent-service` pointing at `service/daemon.js`, configured with `sc.exe failure... actions= restart/0/restart/0/restart/0` and `start= auto`, then immediately starts it — running as LocalSystem on Windows with no opt-in prompt. Once running, three behaviors stack into a remote-control surface against the installer:\n\n1. Self-replacing update channel (`service/updater.js`): a 6-hour interval calls `npm view claw-subagent-service version --json` and, when a newer version is published, runs `npm install -g claw-subagent-service@\u003clatest\u003e` and restarts the worker. Any future tarball published under this name is fetched and executed under LocalSystem (Windows) / user (macOS) without consent and without honoring the operator's pinning. Linux is gated, Windows + macOS are not.\n\n2. Vendor-controlled IM command channel (`service/worker.js`, `service/modules/rongyun-message-handler.js`, `service/modules/script-executor.js`, `service/rongcloud/openclaw-client.js`): the worker fetches a token from `https://newsradar.dreamdt.cn/im/api/claw/token/\u003cnodeId\u003e` and joins a RongCloud IM session (appKey `bmdehs6pbyyks`). `RongyunMessageHandler` dispatches inbound `COMMAND` / `DEVICE_CONTROL` / `CHAT_MESSAGE` messages to handlers that `spawn` `start.sh`/`stop.sh`/`restart.sh`/`status.sh`, run `openclaw doctor --fix`, and feed attacker-supplied prompts into the local AI agent (which can in turn invoke arbitrary tools). Whoever controls the vendor IM backend (or its appKey) has persistent privileged shell-class access to every installer machine.\n\n3. Continuous data exfiltration (`service/modules/heartbeat-dashboard.js`, `service/modules/dashboard-collector.js`): every 30 seconds the worker reads `~/.openclaw/agents/*/sessions/*.jsonl`, `~/.openclaw/projects/projects.json`, `~/.openclaw/tasks/tasks.json`, and the host MAC address, and ships them as 6 RongCloud IM messages to the vendor backend. Includes session contents, model-provider metadata, token-usage events, and a stable host identifier.\n\nThe README documents the product's purpose, but the combination — postinstall privileged-service persistence + 6-hour silent self-replacement + always-on remote-command IM channel + continuous session/host-id upload — is a vendor-operated remote-administration agent installed on the operator's machine via `npm install`. A compromise of the publisher account or the vendor IM backend yields immediate, unattended code execution on every installer host.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in claw-subagent-service (npm)","id":"MAL-2026-3757","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"claw-subagent-service","purl":"pkg:npm/claw-subagent-service","source":"MAL-2026-3757"}],"products":null,"published":"2026-05-14","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-3757/"}
