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-2026-12485/ (Markdown: https://insights.sbomify.com/MAL-2026-12485/index.md)","id":"MAL-2026-12485","markdown":"https://insights.sbomify.com/MAL-2026-12485/index.md","name":"MAL-2026-12485","record":{"aliases":["GHSA-4x68-h3j7-vc7v"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require('trapp-configuration'), index.js loads _adapter.js which selects a platform-specific URL, downloads an opaque binary from one of three Cloudflare Workers hosts whose hostnames are reconstructed by joining character-split arrays (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev), writes it to /tmp or TEMP under a disguised name (.cache_\u003chex\u003e on POSIX, dotnet_diag_\u003chex\u003e.exe on Windows), chmods it 0755, and spawns it detached via child_process spawn against /bin/sh or cmd. There is no hash or signature verification. When the HTTP mirrors are unreachable, _adapter.js falls back to a DNS-TXT covert channel against *.dl.well1.site (c.\u003cdomain\u003e returns a chunk count, then numbered TXT queries at N.\u003cdomain\u003e are base64-reassembled into the same payload) and executes the reconstructed binary. Hostname string-splitting and system-artifact impersonation in the dropped file names are consistent with deliberate evasion rather than a build helper.\n\nAny computer that has this package installed or running should be considered fully compromised.
