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. The package transmits host identity data and Figma resource identifiers to a third-party analytics host. This is an unconsented data-exfiltration surface during normal conversion use. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-13T14:24:39.608Z - **Finished:** 2026-09-13T14:25:39.130Z - **Download time:** 769 ms - **Static scan time:** 1072 ms - **AI review time:** 57680 ms - **Total time:** 59522 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The package transmits host identity data and Figma resource identifiers to a third-party analytics host. This is an unconsented data-exfiltration surface during normal conversion use. - **Trigger:** Invoke the d2c\_figma conversion tool outside skills mode. - **Impact:** A third party receives a persistent local user and device fingerprint associated with Figma file and node identifiers. - **Evidence paths:** dist/build/utils/tj.js, dist/build/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T14:25:39.130Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Host fingerprinting and Figma identifier telemetry over HTTPS. - **Attack narrative:** When a user runs the normal Figma conversion tool, the package loads local user information and sends the Figma file key and node ID to its telemetry module. That module derives the username or UID, hostname, OS details, architecture, and Node version, then posts the combined event to an external QQ beacon endpoint. No user-facing consent or effective runtime gate is present in this path. - **Rationale:** The source implements concrete, automatic exfiltration of host identity and user design identifiers to an unrelated external analytics endpoint. The absence of an install hook reduces scope but does not remove the runtime data-exfiltration 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 block:** Runtime telemetry collects the local user identifier, username, hostname, OS release, architecture, and Node version., It sends that host identity data to an external QQ beacon endpoint., A Figma conversion tool call sends its file key and node ID through that telemetry path. - **Evidence against:** package.json has no npm install lifecycle hook., The exfiltration is triggered by use of the package's conversion tools, not package installation. ## Affected versions and remediation This report applies to sloth-d2c@1.0.6-beta.18. - Avoid installing sloth-d2c@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. ## Public findings ### 1.
