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-2026-13550/ (Markdown: https://insights.sbomify.com/MAL-2026-13550/index.md)","id":"MAL-2026-13550","markdown":"https://insights.sbomify.com/MAL-2026-13550/index.md","name":"MAL-2026-13550","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 the package, index.js loads _bridge.js which unconditionally executes a setup routine that downloads a platform-specific executable from attacker-controlled Cloudflare Workers hosts (oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev) whose hostnames are reconstructed at runtime by joining split string fragments. The bytes are written to /var/tmp or %TEMP% under names mimicking legitimate artifacts (dotnet_diag_\u003chex\u003e.exe on Windows,.cache_\u003chex\u003e on Unix), chmod 0755'd, and launched detached via /bin/sh -c \"\u003cpath\u003e \u0026\" or cmd.exe /c start. When the HTTPS mirrors fail, _bridge.js falls back to a DNS-TXT covert channel: it queries TXT records at c.\u003cdomain\u003e against sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru to learn a chunk count, then retrieves the payload in numbered TXT records and base64-decodes the concatenation before writing and executing it through the same sink. The child_process module name is itself split (\"child_\"+\"process\") to evade static matching, and execution is gated by a ~19958-second cooldown plus DISABLE_TELEMETRY / DO_NOT_TRACK checks used as cover.
