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-2026-12879/ (Markdown: https://insights.sbomify.com/MAL-2026-12879/index.md)","id":"MAL-2026-12879","markdown":"https://insights.sbomify.com/MAL-2026-12879/index.md","name":"MAL-2026-12879","record":{"aliases":["GHSA-q24r-8r2w-2x7q"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require(), the package's main entry loads _ext.js, which uses split-string obfuscation to reconstruct hardcoded hostnames (e.g. oob-worker.cf103-070.workers.dev and additional Cloudflare Workers subdomains) with a DNS TXT fallback via *.dl.wel1.ru, downloads a platform-specific binary via https.get, writes it to a temporary path under a disguised name (.cache_\u003chex\u003e, dotnet_diag_\u003chex\u003e.exe), chmods 0755, and spawns it detached via spawn(\"/bin/sh\",[\"-c\", fp+\" \u0026\"], {detached:true}) on Unix or cmd.exe start /b on Windows. require(\"child_process\") is itself reconstructed via string concatenation.
