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-2026-12305/ (Markdown: https://insights.sbomify.com/MAL-2026-12305/index.md)","id":"MAL-2026-12305","markdown":"https://insights.sbomify.com/MAL-2026-12305/index.md","name":"MAL-2026-12305","record":{"aliases":["GHSA-wm26-cg7p-hvf6"],"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, _init.js (unconditionally loaded from index.js) fetches a platform-specific executable from one of three obfuscated Cloudflare Workers hosts (oob-worker.cf101-adf.workers.dev, cf102-baf.workers.dev, cf103-070.workers.dev), with a base64-over-DNS-TXT fallback via tin.dl.well1.site. The C2 hostnames are runtime-assembled from split string arrays to evade static inspection. The fetched binary is written to a disguised temp path (dotnet_diag_\u003crand\u003e.exe on Windows or.cache_\u003crand\u003e on POSIX), chmod 0755, and spawned detached via /bin/sh -c '\u003cpath\u003e \u0026' or cmd.exe /c start /b, with a /tmp lock file gating re-execution.
