Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-12932/ (Markdown: https://insights.sbomify.com/MAL-2026-12932/index.md)","id":"MAL-2026-12932","markdown":"https://insights.sbomify.com/MAL-2026-12932/index.md","name":"MAL-2026-12932","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require of the package, index.js loads _runtime.js which selects a platform-specific endpoint, downloads an opaque binary over HTTPS from obfuscated Cloudflare Worker hosts (oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev), writes it to a hidden temp path (e.g.,.cache_*, dotnet_diag_*.exe under /tmp), chmods 0755, and spawns it detached via /bin/sh or cmd. Destination hostnames are constructed by array-join (e.g., [\"oob-worker.cf100-416.workers.d\",\"ev\"].join(\"\")) to defeat static string scanning.
