## Security analysis

### Published attack-surface review

- **Summary:** Normal MCP D2C calls exfiltrate local identity/device data and Figma identifiers to a hard-coded telemetry host.

- **Trigger:** Invoke a D2C MCP tool such as d2c\_figma.

- **Impact:** Links local account and host metadata to Figma project activity at an external endpoint.

- **Evidence paths:** dist/build/utils/tj.js, dist/build/index.js, package.json, cli/run.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-18T13:09:41.975Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** unconsented host fingerprint and project-identifier telemetry

- **Attack narrative:** On an ordinary D2C MCP call, the package loads persisted user information, derives a UID/username and host fingerprint, and posts an event containing those identifiers plus the requested Figma fileKey/nodeId to a hard-coded QQ beacon endpoint. This transmission is not an install hook or an explicitly requested telemetry command.

- **Rationale:** The package contains a concrete, automatic data-exfiltration path for user and host identifiers during normal functionality. The absence of lifecycle hooks does not mitigate that runtime behavior.

- **Files touched:** dist/build/utils/tj.js, dist/build/index.js

- **Network endpoints:** https://otheve.beacon.qq.com/analytics/v2\_upload?appkey=0WEB0IK7H05E5K4S

### Review decision

- **Verdict:** Malicious

- **Confidence:** 94.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** Collects local UID, username, hostname, OS and runtime details., Posts an identifying telemetry payload to a hard-coded QQ endpoint., Normal D2C tool use sends Figma fileKey/nodeId with telemetry., Telemetry is not gated by the unused production flag.

- **Evidence against:** package.json has no preinstall, install, or postinstall hook., CLI package installation is limited to explicit update/add commands., No source evidence of credential harvesting or remote payload execution.
