## Verdict summary
**Blocked & quarantined** — Links a local user and host fingerprint to design-resource identifiers at a third-party endpoint.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Data Exfiltration
- **Selected version:** 1.0.6-beta.18
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

A D2C conversion transmits local account and host fingerprints together with Figma file and node identifiers to an external beacon service. This is not limited to a local service or required Figma API call.

## Security analysis

### Published attack-surface review

- **Summary:** A D2C conversion transmits local account and host fingerprints together with Figma file and node identifiers to an external beacon service. This is not limited to a local service or required Figma API call.

- **Trigger:** Running a normal D2C conversion through the CLI, MCP server, or skills flow.

- **Impact:** Links a local user and host fingerprint to design-resource identifiers at a third-party endpoint.

- **Evidence paths:** dist/build/utils/tj.js, dist/build/index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-13T14:25:57.488Z

### AI review details

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

- **Mechanism:** Unconsented telemetry-based data exfiltration.

- **Attack narrative:** After a user starts a D2C conversion, the package builds a beacon event containing local account identity, hostname and platform details. It also includes the Figma file key and node ID from the conversion request. The event is posted to an external beacon endpoint without a visible opt-in or configuration gate, exposing a correlatable user, machine, and design-resource record.

- **Rationale:** The package contains concrete, automatically triggered exfiltration of local identity and host data to an unrelated beacon endpoint during its normal operation. The absence of an install hook does not remove this runtime privacy attack surface.

- **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 block:** The telemetry code collects the hostname, operating-system details, and local account identifier and name., It posts a combined account fingerprint and device fingerprint to an external beacon host., A normal D2C conversion sends the supplied Figma file and node identifiers through that telemetry path.

- **Evidence against:** package.json contains no npm preinstall, install, or postinstall hook., The observed process spawning and package update actions require explicit CLI subcommands.

## Affected versions and remediation

This report applies to sloth-d2c-mcp@1.0.6-beta.18.

- Avoid installing sloth-d2c-mcp@1.0.6-beta.18. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
