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. Importing either primary package entry point in a browser-like environment fetches and executes remote JavaScript. The loader is concealed inside obfuscated distribution bundles. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-07T13:12:10.875Z - **Finished:** 2026-09-07T13:13:40.299Z - **Download time:** 507 ms - **Static scan time:** 6649 ms - **AI review time:** 82267 ms - **Total time:** 89424 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:** Importing either primary package entry point in a browser-like environment fetches and executes remote JavaScript. The loader is concealed inside obfuscated distribution bundles. - **Trigger:** Import or require the package where document is available. - **Impact:** A CDN-controlled payload can execute with the importing application's browser privileges. - **Evidence paths:** dist/core.cjs.js, dist/core.esm.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T13:13:40.299Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic remote script injection and execution. - **Attack narrative:** The package's public import and require entry points resolve to obfuscated bundles. In browser-like environments, each bundle automatically injects a script URL from a Tencent Music CDN. Because this is executable JavaScript loaded at import time rather than a pinned package dependency, control of the remote resource can change code executed by consumers without a package update. - **Rationale:** The package contains an automatic, obfuscated remote-code loader in both primary entry points. Although no install hook exists and the URL suggests a formatter dependency, the import-time execution of mutable remote code is a concrete supply-chain attack surface. - **Files touched:** dist/core.cjs.js, dist/core.esm.js - **Network endpoints:** https://cdn-y.tencentmusic.com/sloth/d2c/sdk/prettier@3.5.3/standalone.js ### Review decision - **Verdict:** Malicious - **Confidence:** 90.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Both published module entry points automatically load executable JavaScript from a remote CDN when a document exists., The remote loader is embedded in heavily obfuscated bundles, obscuring the code path and payload handling., The manifest exposes those bundles as the package import and require entry points. - **Evidence against:** No npm preinstall, install, or postinstall lifecycle hook is declared., The remote resource is named as a Prettier standalone library, consistent with formatting functionality. ## Affected versions and remediation This report applies to sloth-d2c-figma-plugin@2.0.4-beta.21. - Avoid installing sloth-d2c-figma-plugin@2.0.4-beta.21. 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.
