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 obfuscated React component performs remote license revocation checks during component use. An invalid result can erase the consumer page body outside localhost. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-07T15:05:22.757Z - **Finished:** 2026-09-07T15:06:08.866Z - **Download time:** 251 ms - **Static scan time:** 105 ms - **AI review time:** 45752 ms - **Total time:** 46109 ms The recorded confidence comes from the underlying analysis.

An invalid result can erase the consumer page body outside localhost. - **Trigger:** Rendering the ProgressiveImage component with an invalid or revoked license result. - **Impact:** Denial of service to the consumer web application and remote control over whether it renders. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T15:06:08.866Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote license enforcement followed by DOM replacement. - **Attack narrative:** A consumer that directly imports and renders the obfuscated component runs a signed-license check and requests a remote revocation list. If the license is invalid and the application is not on localhost, the component replaces the entire document body with an empty div. This hidden, remotely influenced application-disabling behavior is not part of a progressive-image component and is not disclosed by the package README. - **Rationale:** The package embeds concealed remote license enforcement that can destroy a consumer application's visible DOM at runtime. This is concrete destructive behavior, despite the absence of install hooks or observed secret theft. - **Files touched:** index.js, document.body, IndexedDB verify-cache - **Network endpoints:** https://api.npoint.io/f63d2269d3d045f8cdc3 ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js is heavily obfuscated and contains hidden license-verification code unrelated to progressive image rendering., When a license is invalid outside localhost, index.js replaces the document body with a new empty div, breaking the consumer application., Component use fetches a remotely controlled revocation list from api.npoint.io and caches the result in IndexedDB., The manifest points to a missing lib/index.js entrypoint, while the obfuscated behavior is kept in a separate index.js file., On an invalid non-localhost license, the component replaces the document body with a new div. - **Evidence against:** package.json has no install or lifecycle scripts., No shell execution, dynamic code execution, credential harvesting, or filesystem access was found in the inspected files. ## Affected versions and remediation This report applies to rc-progressive-image@2.0.6. - Avoid installing rc-progressive-image@2.0.6. 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.
