## Security analysis

### Published attack-surface review

- **Summary:** The install hook fetches and installs an executable payload from a hardcoded IP endpoint with TLS verification disabled. The packaged CLI later runs that installed binary.

- **Trigger:** npm install runs postinstall; invoking onecode runs the installed binary

- **Impact:** Remote endpoint can supply arbitrary executable code outside npm package integrity controls

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

- **Review source:** ai\_review

- **Reviewed:** 2026-07-04T23:21:51.289Z

### AI review details

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

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

- **Attack narrative:** On install, postinstall.mjs builds a URL under a hardcoded IP host, downloads a tarball with certificate verification disabled, extracts it, moves the extracted package into node\_modules, chmods its native binary, and links or copies it to bin/.onecode. The public bin/onecode wrapper resolves that cached binary and spawns it with user arguments.

- **Rationale:** This package delegates its installed executable to unauthenticated install-time network content, creating a concrete remote code execution supply-chain risk even though the wrapper is CLI-aligned. No source evidence shows credential theft or AI-agent control-surface hijacking.

- **Files touched:** postinstall.mjs, bin/onecode, node\_modules/onecode-\<platform\>-\<arch\>, bin/.onecode, /tmp/onecode-\<platform\>-\<arch\>-\<version\>.tgz, /tmp/onecode-\<platform\>-\<arch\>-\<version\>-extract

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

### Review decision

- **Verdict:** Malicious

- **Confidence:** 88.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs postinstall: node ./postinstall.mjs, postinstall.mjs downloads a tgz from https://218.90.133.98:4443/onecode\_tgz during install, postinstall.mjs uses https.get with rejectUnauthorized:false, disabling TLS certificate validation, postinstall.mjs extracts downloaded archive with tar and installs/chmods bin/.onecode, bin/onecode executes the installed/downloaded binary via child\_process.spawn

- **Evidence against:** No credential harvesting, home-directory agent config writes, persistence hooks, or destructive filesystem behavior found in package source, CLI wrapper behavior is package-aligned for a native binary tool
