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 automatically collects and transmits host information. Its registry manifest exposes this executable payload as several registry assets. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-02T00:17:57.051Z - **Finished:** 2026-10-02T00:18:51.667Z - **Download time:** 765 ms - **Static scan time:** 9 ms - **AI review time:** 53841 ms - **Total time:** 54616 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 automatically collects and transmits host information. Its registry manifest exposes this executable payload as several registry assets. - **Trigger:** Importing or otherwise evaluating thunderboltRegistry.js in an environment with the relevant APIs available. - **Impact:** Unconsented disclosure of hostname, process, user identity and kernel information; local system commands execute during payload loading. - **Evidence paths:** thunderboltRegistry.js, registry-manifest.min.json, package.json - **Review source:** ai\_review - **Reviewed:** 2026-10-02T00:18:51.667Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** An immediate function reads process metadata and the hostname, executes system identification commands, and sends results through fetch to external collection endpoints. - **Attack narrative:** The package ships an executable registry asset that immediately fingerprints its execution environment and sends collected information to external endpoints. It also invokes local system identification commands. The default package import is inert, but directly loading the shipped registry asset activates the collection without a user command or opt-in. - **Rationale:** Inspected source demonstrates automatic external transmission of host and user information unrelated to CSS utilities. The inert default entrypoint limits activation but does not neutralize the active payload exposed through the registry manifest. - **Network endpoints:** davdpb8lhot13kgmnhp0863x9g83mpswq.oast.live, https://webhook.site/0492a36c-4d7b-408a-865c-226db25987ba ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** thunderboltRegistry.js immediately collects the hostname and process metadata and sends them to an external host., thunderboltRegistry.js executes id and uname -r and transmits system information., The same executable code sends collected host and user information to webhook.site without consent., registry-manifest.min.json maps registry assets to the executable thunderboltRegistry.js payload., package.json ships the registry payload, although its default index.js entrypoint exports an empty object. - **Evidence against:** No install lifecycle hook or runtime dependency is declared., The default index.js entrypoint does not activate the payload; loading thunderboltRegistry.js does. ## Affected versions and remediation This report applies to rgx33-css-grid-utils@1.0.0. - Avoid installing rgx33-css-grid-utils@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.
