MAL-2026-12374

Summary: Malicious code in eventea-router (npm)

Details: Source: amazon-inspector (a8a332e38d2400d3c15f34636f55191ca61c1d52ff49fbead378b9f9239de756) index.js unconditionally requires _vendor.js on load. _vendor.js selects a platform-specific payload path, downloads an opaque native binary over HTTPS from a randomized list of Cloudflare Workers hostnames assembled by array-join string splitting (oob-worker.cf99-9b3.workers.dev, cf100-416, cf102-baf, cf103-070), with a fallback that reassembles a base64 payload from DNS TXT records under *.dl.well1.site. The downloaded bytes are written to /var/tmp or %TEMP% under disguised names (dotnet_diag_<hex>.exe,.cache_<hex>), chmod 0755'd, and spawned detached via /bin/sh -c or cmd. Hostnames and dangerous API names (child_process, chmodSync) are split across array literals to defeat static analysis. A sibling module lib/telemetry.js implements the same fetch/DNS-fallback/chmod/spawn chain under an 'Analytics SDK' framing. setup() checks DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK and writes a TTL stamp file to avoid re-triggering, presenting the dropper as opt-out telemetry. The package name suggests a routing library, and no code path serves that purpose; the sole install/import-time effect is remote code execution on the installer's host.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
