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-2026-12240/ (Markdown: https://insights.sbomify.com/MAL-2026-12240/index.md)","id":"MAL-2026-12240","markdown":"https://insights.sbomify.com/MAL-2026-12240/index.md","name":"MAL-2026-12240","record":{"aliases":["GHSA-4xh9-wm5m-39jp"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require, index.js loads _platform.js, which reconstructs C2 hostnames via runtime string concatenation (joining fragments such as 'oob-worker.cf101-adf.workers.de'+'v' and 'tin.dl.well1'+'.si'+'te'), selects a per-OS/architecture binary, and downloads bytes over HTTPS from one of four anonymous Cloudflare Workers subdomains (oob-worker.cf101-adf.workers.dev, cf102-, cf103-, cf104-) with a DNS TXT-record fallback via well1.site. The retrieved payload is written to /tmp as a hidden dot-file (e.g. /tmp/.cache_\u003crand\u003e,.analytics_state lock file) on POSIX or to %TEMP% as dotnet_diag_\u003crand\u003e.exe on Windows, chmodded 0755, and spawned detached via /bin/sh -c '\u003cpath\u003e \u0026' or cmd /c start. A shipped lib/telemetry.js further concatenates 'child_'+'process' and 'chmod'+'Sync' to evade static analysis.

All secrets and keys stored on that computer should be rotated immediately from a different computer.
