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. Rendering the Crop component performs an obfuscated remote licence-revocation check. The remote result can suppress the cropper and invoke document manipulation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-07T14:45:13.057Z - **Finished:** 2026-09-07T14:46:40.119Z - **Download time:** 251 ms - **Static scan time:** 116 ms - **AI review time:** 86694 ms - **Total time:** 87062 ms The recorded confidence comes from the underlying analysis.

The remote result can suppress the cropper and invoke document manipulation. - **Trigger:** A consumer renders the exported Crop component in a browser. - **Impact:** The endpoint operator can remotely disable the component in deployed consumer applications. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T14:46:40.119Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote revocation kill switch. - **Attack narrative:** The package loads its obfuscated entrypoint when imported. When its React component is rendered, it verifies a baked-in or supplied licence and fetches a revocation list from a third-party endpoint. If that list marks the licence revoked, the component changes to an invalid state, performs an obfuscated document operation, and returns no cropper. This concealed remote kill switch is unrelated to ordinary image-cropping behavior and lets the endpoint operator alter deployed application behavior. - **Rationale:** This is a concealed, remotely controlled kill switch in a browser component, protected by deliberate obfuscation. It has no install-time hook or secret harvesting, but the concrete remote disablement behavior warrants blocking. - **Files touched:** index.js - **Network endpoints:** https://api.npoint.io/f63d2269d3d045f8cdc3 ### Review decision - **Verdict:** Malicious - **Confidence:** 91.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package entrypoint is index.js., The entrypoint is deliberately string-table obfuscated, concealing its browser behavior., It contains a hard-coded remote revocation endpoint and fetches it when the component is used., A remote revocation result changes the component to invalid and enters a document-manipulation branch instead of rendering the cropper. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The inspected package contains no Node child-process, credential, or filesystem-harvesting code., The remote response is parsed as a revocation list, not executed as code. ## Affected versions and remediation This report applies to rc-image-crop@1.0.5. - Avoid installing rc-image-crop@1.0.5. 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.
