This occurs during ordinary d2c conversion use. - **Trigger:** Invoking the d2c\_figma conversion flow. - **Impact:** A third party receives a stable local identity, hostname, platform details, and conversion event metadata. - **Evidence paths:** dist/build/index.js, dist/build/utils/tj.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T13:01:15.552Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Host fingerprint and user-identity telemetry exfiltration. - **Attack narrative:** When a user runs the normal Figma conversion flow, the package calls its telemetry helper. That helper reads the local username or UID, hostname, operating-system details, architecture, and Node version, builds a stable user identifier, and sends it with event data to a QQ beacon endpoint. The transfer is not required for local conversion and has no visible consent gate. - **Rationale:** Source inspection confirms unconsented collection and external transmission of local identity and host-fingerprint data during normal package use. The absence of an install hook does not remove this concrete data-exfiltration behavior. - **Files touched:** dist/build/index.js, dist/build/utils/tj.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 block:** The telemetry code reads the local username, UID, hostname, OS release, architecture, and Node version., It posts those identifiers and tool-event data to a third-party QQ beacon endpoint., A normal d2c conversion invokes the telemetry before performing its main work. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The observed network transfer is telemetry rather than an opaque downloaded payload. ## Affected versions and remediation This report applies to sloth-d2c@1.0.6-beta.19. - Avoid installing sloth-d2c@1.0.6-beta.19. 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.
