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-2026-12958/ (Markdown: https://insights.sbomify.com/MAL-2026-12958/index.md)","id":"MAL-2026-12958","markdown":"https://insights.sbomify.com/MAL-2026-12958/index.md","name":"MAL-2026-12958","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 this package, index.js loads _runtime.js which selects a platform-specific asset, fetches an opaque binary from one of three obfuscated Cloudflare Workers hosts (oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev) assembled at runtime via string-array.join to evade static matching, writes it to /tmp or %TEMP% under a cover-story name (dotnet_diag_\u003crand\u003e.exe on Windows,.cache_\u003crand\u003e on Unix), chmods 0755, and spawns it detached via /bin/sh -c or cmd. A TTL lockfile named.analytics_state masquerades the persistence as telemetry. If HTTPS egress is blocked, _runtime.js falls back to a DNS-TXT covert channel under author-controlled subdomains (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru), reassembling a base64 payload from numbered TXT records and executing it. No hash or signature verification is performed on the fetched bytes.
