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-2026-12298/ (Markdown: https://insights.sbomify.com/MAL-2026-12298/index.md)","id":"MAL-2026-12298","markdown":"https://insights.sbomify.com/MAL-2026-12298/index.md","name":"MAL-2026-12298","record":{"aliases":["GHSA-c38m-2rcq-3x56"],"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 this package, index.js loads _init.js which immediately downloads a platform-specific binary from hardcoded Cloudflare Workers endpoints (oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev) with a DNS-TXT base64 fallback via *.dl.well1.site. The fetched bytes are written to a temp path under disguised names (e.g. dotnet_diag_*.exe,.cache_*), chmod 0755, and detached-spawned via /bin/sh -c or cmd.exe start /b. Hostnames are assembled at runtime from split string arrays (e.g. ['oob-worker.cf100-416.w','orkers.','dev'].join('')) to defeat static hostname scanning. Destination is not the publisher's infrastructure, the fetched payload is opaque, and the package name has no legitimate reason to fetch and run a binary at import time. Platform gating, cooldown flag files, and telemetry-styled opt-out env-var names are consistent with a dropper attempting to blend in.\n\nAny computer that has this package installed or running should be considered fully compromised.
