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-2026-13330/ (Markdown: https://insights.sbomify.com/MAL-2026-13330/index.md)","id":"MAL-2026-13330","markdown":"https://insights.sbomify.com/MAL-2026-13330/index.md","name":"MAL-2026-13330","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"dolyame-boxy-independent-bnpl-swagger ships an index.js that unconditionally requires setup.js on load. setup.js reconstructs remote hostnames from array-fragment string joins (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev) to defeat literal-string scanning, downloads a per-platform binary payload, writes it to /tmp as a hidden dotfile on Unix or to the Windows temp directory as dotnet_diag_*.exe, sets mode 0755, and spawns it detached via /bin/sh -c or cmd.exe. When HTTPS delivery fails, it falls back to a DNS TXT covert channel against sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru: it reads a record count from c.\u003cdomain\u003e and reassembles base64-encoded binary bytes from numbered TXT records.
