## Public findings

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

streak-metric-test@1.0.0 ships a fully wired dropper that fires on \`import\`/\`require\` of the package root. The top-level async IIFE in dist/index.mjs assembles a Buffer from a base64 string array, writes it to \`~/.cache/streak-metric/h\`, chmods it 0o755, and detach-spawns it via \`child\_process.spawn(..., { detached: true, stdio: 'ignore' }).unref()\`. The supporting primitives (\`ensureDir\`, \`writeBinary\`, \`runDetached\`) live in dist/internal/daymath.mjs alongside unrelated day-math helpers, with docstrings (\`"Start a background task"\`, \`"Save data to cache"\`) that mislabel the chmod-executable + detached-spawn behavior as benign caching. The payload array is currently \`\[""\]\` (inert), but the decode→write→chmod+x→detached-spawn chain is complete and only requires populating one string to arm; the package name suffix \`-test\`, the cover-story comments, and the hidden cache path are consistent with a staging artifact rather than legitimate functionality. No native addon, no declared purpose that would justify writing and executing an opaque binary from an in-source blob at import.
