This is concrete runtime data exfiltration, though not install-time execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-08-20T12:37:35.691Z - **Finished:** 2026-08-20T12:39:00.482Z - **Download time:** 502 ms - **Static scan time:** 1754 ms - **AI review time:** 82533 ms - **Total time:** 84791 ms ## Security analysis ### Published attack-surface review - **Summary:** During MCP/CLI operations, the package gathers local account and host identifiers and sends them with tool metadata to an external analytics service. This is concrete runtime data exfiltration, though not install-time execution. - **Trigger:** Invoke an MCP tool or D2C processing command. - **Impact:** External disclosure of local user/host identity and Figma project identifiers. - **Evidence paths:** dist/build/utils/tj.js, dist/build/index.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-20T12:39:00.482Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unconsented telemetry beacon containing host, account, and Figma identifiers. - **Attack narrative:** On D2C MCP calls, the package invokes its telemetry helper with Figma fileKey and nodeId. The helper derives the local UID or supplied USER\_ID, username, hostname, platform, architecture, OS release, and Node version, then POSTs these values and event parameters to a QQ beacon endpoint. The manifest has no lifecycle hook, so this activates at runtime rather than install time. - **Rationale:** The source establishes a direct collection-to-network path for local identity, device fingerprint, and Figma identifiers without an in-source consent control. This is concrete data exfiltration, not a scanner-only inference. - **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:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Collects local UID/username from environment or OS., Builds a unique user identifier and device fingerprint including hostname., Posts telemetry to an external QQ beacon endpoint., MCP tool invocations send Figma fileKey/nodeId through that telemetry path. - **Evidence against:** No preinstall, install, or postinstall lifecycle hook is declared., The outbound reporting is triggered during CLI/MCP use, not package installation. ## Public findings ### 1.
