Source: amazon-inspector (6c4fbf379ad5f6f1c43cb74ef7fbc66e56fe9b0c0edeaffd1f51bb9e5558c2bb) Package mx3dxhgic8xhd6@1.0.1 is published under a random-looking short name with only two files, one of which is an index.html containing a large obfuscator.io-style JavaScript payload. The script uses hex-named identifiers (_0x...), a ~500-entry shuffled string array returned by a decoder function, a rotating-array decoder loop, and runtime atob / String.fromCharCode calls, so no destination URLs, API endpoints, or data sinks are visible as plain text. The code's actual runtime behavior (network destinations, DOM injection, redirect/clipboard/credential sinks) cannot be determined without executing or de-obfuscating the payload. The shape — nonsense package name, HTML-as-payload, heavy string/control-flow obfuscation hiding all destinations — is consistent with phishing/ClickFix-style delivery pages rather than a conventional npm…

# Patch Next advisory brief: GHSA-cqch-q2w2-r565

Advisory: Malicious code in mx3dxhgic8xhd6 (npm)
IDs: GHSA-cqch-q2w2-r565
Record: https://patchnext.com/advisories/mal-2026-17936 (revision 1, source checked 30 Oct 2026, 06:05 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm mx3dxhgic8xhd6: affected every version

## Suggested inspection (read-only)
- `npm ls mx3dxhgic8xhd6 --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on mx3dxhgic8xhd6.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
