## Security analysis

### Published attack-surface review

- **Summary:** The package performs unauthenticated install-time native binary delivery from a raw IP endpoint. The downloaded binary is extracted and wired into the package CLI without an integrity check.

- **Trigger:** npm install postinstall lifecycle, then onecode CLI execution

- **Impact:** Remote endpoint or MITM can supply the executable later invoked by users as onecode.

- **Evidence paths:** package.json, postinstall.mjs, bin/onecode

- **Review source:** ai\_review

- **Reviewed:** 2026-07-04T23:21:57.671Z

### AI review details

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

- **Mechanism:** install-time remote binary download and execution wrapper

- **Attack narrative:** On install, postinstall.mjs downloads a platform tgz from a hardcoded IP over HTTPS while disabling certificate validation, extracts it with tar, places it under package-local node\_modules, and links/copies the binary to bin/.onecode. The public bin/onecode wrapper then spawns that installed binary for user commands.

- **Rationale:** This is concrete install-time remote executable staging from an unauthenticated endpoint with no observed integrity verification. Although the behavior is package-aligned for a native CLI and not an AI-agent control hijack, the delivery path is unsafe enough to block.

- **Files touched:** postinstall.mjs, .postinstall-work, node\_modules/onecode-\<platform\>-\<arch\>, bin/.onecode, bin/onecode

- **Network endpoints:** https://218.90.133.98:4443/onecode\_tgz

### Review decision

- **Verdict:** Malicious

- **Confidence:** 94.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs install-time hook: node ./postinstall.mjs, postinstall.mjs downloads a platform tgz from https://218.90.133.98:4443/onecode\_tgz, postinstall.mjs disables TLS certificate verification with rejectUnauthorized:false, postinstall.mjs extracts the downloaded tgz and installs/chmods a binary during postinstall, bin/onecode executes the installed/cached binary and allows override via ONECODE\_BIN\_PATH or OPENCODE\_BIN\_PATH

- **Evidence against:** No credential harvesting, home-agent config writes, persistence hooks, or destructive file operations found, Writes appear limited to package-local .postinstall-work, node\_modules, and bin/.onecode
