## Security analysis

### Published attack-surface review

- **Summary:** Importing the package's advertised ./package.json export executes setup.js. It attempts to plant a Hono/Deno handler that harvests local flags and environment data and returns it to HTTP callers.

- **Trigger:** Consumer imports z-deno-truth-bwhlsz/package.json.

- **Impact:** Can alter an application pages directory and expose host secrets through a planted route.

- **Evidence paths:** package.json, setup.js, index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-25T20:13:29.666Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Deceptive export-time web-handler dropper for local secret harvesting.

- **Attack narrative:** The manifest makes the normal-looking package.json subpath execute setup.js. That module writes a TSX handler into /app/pages/h.tsx when permitted; the handler reads flag locations, root/app directory listings, process environment data, and /readflag content, then returns the results in an HTTP response. It also drops the same handler in /tmp.

- **Rationale:** This is concrete secret-harvesting and application-file mutation hidden behind a deceptive export, despite lacking an install hook or direct network call.

- **Files touched:** package.json, setup.js, /tmp/h.tsx, /app/pages/h.tsx, /proc/self/environ, /readflag

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json deceptively maps ./package.json to setup.js., setup.js runs synchronously when that export is imported., setup.js writes a Deno handler to /tmp/h.tsx and /app/pages/h.tsx., Embedded handler reads common flag paths, /proc/self/environ, and Deno.env., Handler exposes collected file and environment contents in its HTTP response.

- **Evidence against:** No npm lifecycle scripts are declared., No network endpoint or direct exfiltration code is present in inspected files.
