Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Loading thunderboltRegistry.js activates host reconnaissance and exports results to fixed external recipients. The bundled registry manifest exposes this executable module to registry loaders. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-03T22:48:03.949Z - **Finished:** 2026-10-03T22:48:55.064Z - **Download time:** 773 ms - **Static scan time:** 11 ms - **AI review time:** 50330 ms - **Total time:** 51115 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:** Loading thunderboltRegistry.js activates host reconnaissance and exports results to fixed external recipients. The bundled registry manifest exposes this executable module to registry loaders. - **Trigger:** Loading thunderboltRegistry.js directly or through a loader using registry-manifest.min.json. - **Impact:** Exposes the hostname, user identity, operating-system information, hosts-file content, and network configuration. - **Evidence paths:** thunderboltRegistry.js, registry-manifest.min.json - **Review source:** ai\_review - **Reviewed:** 2026-10-03T22:48:55.064Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** An immediately invoked function executes reconnaissance commands and sends output through HTTP requests and encoded DNS queries. - **Attack narrative:** The package bundles a registry module whose loading immediately gathers host information, runs shell reconnaissance commands, and exports results to fixed HTTP and DNS recipients. Its manifest maps several registry names to that module. Although the default entrypoint is inert, the shipped registry module contains active data-exfiltration behavior unrelated to CSS color utilities. - **Rationale:** Inspected source establishes automatic reconnaissance and data export when the registry module loads. The inert default entrypoint limits activation but does not neutralize the executable payload. - **Files touched:** /etc/hosts - **Network endpoints:** https://dxpoc.gt.tc/callback.php/bb8968d0f67000433bf7005dd5ad2d1f, davdpb8lhot13kgmnhp0863x9g83mpswq.oast.live ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** thunderboltRegistry.js executes shell commands to read host and network information and passes their output to an export function., The export function sends collected data and the hostname through HTTP requests to a fixed unrelated recipient., The module defines fixed HTTP and DNS collection endpoints., registry-manifest.min.json directs registry loaders to thunderboltRegistry.js., The registry module executes immediately and deletes matching entries from the module cache. - **Evidence against:** index.js only exports an empty object, and package.json has no lifecycle hooks; ordinary main-entrypoint imports do not activate the payload. ## Affected versions and remediation This report applies to css-relative-color-util@1.0.0. - Avoid installing css-relative-color-util@1.0.0. 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.
