## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

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. No documentation describes what code is unpacked and run on the installer's machine.
