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-2026-4547/ (Markdown: https://insights.sbomify.com/MAL-2026-4547/index.md)","id":"MAL-2026-4547","markdown":"https://insights.sbomify.com/MAL-2026-4547/index.md","name":"MAL-2026-4547","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package's `main` is an ARM ELF binary that, when loaded, mkdtemp's a working directory under `/dev/shm/.cxpher.XXXXXX` or `/tmp/.cxpher.XXXXXX`, writes an unpacked JavaScript file (`a.js` and `/tmp/.cxpher-wrap.%d.js`), locates `node` at `/usr/local/bin/node` or `/usr/bin/node`, and execvp's node against the unpacked file. The bytes that ultimately run are decoded from an opaque high-entropy blob inside the ELF and are not human-auditable from the published tarball — equivalent to `eval(decode(blob))` but in native form. The same binary reads `/proc/self/status` and parses the `TracerPid:` field, the canonical Linux anti-ptrace anti-debug check; legitimate native addons do not need this. Package metadata is placeholder (no author, homepage, repository, or README; description is the generic string \"Native binary for cxpher on linux-arm32\"), and the binary references an alternate environment-variable prefix (`AGPK_AUDIO_FD` alongside `CXPHER_AUDIO_FD`) suggesting it was renamed/repurposed from a different project.
