## Security analysis

### Published attack-surface review

- **Summary:** The npm postinstall hook can fetch and install an unauthenticated platform executable from a hardcoded IP endpoint. The binary payload is not included in the inspected source and is not integrity-checked before being installed as the CLI target.

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

- **Impact:** Remote endpoint or network attacker can supply the executable that becomes the package CLI binary.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-07-04T23:23:49.034Z

### AI review details

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

- **Mechanism:** install-time remote binary download without TLS validation or integrity check

- **Attack narrative:** On install, package.json runs postinstall.mjs, which calls platform-bootstrap.mjs. If the platform package is absent, it downloads a versioned tgz from a hardcoded IP over HTTPS with certificate verification disabled, extracts it with tar, installs the binary under node\_modules, chmods it executable, and links/copies it to bin/.onecode. The wrapper later spawns that binary for user CLI invocations.

- **Rationale:** This package uses an npm lifecycle hook to install an opaque executable from a hardcoded remote IP with certificate validation disabled and no source-visible integrity check. That creates a concrete staged payload delivery path rather than a merely user-invoked package-aligned CLI bootstrap.

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

- **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 defines postinstall: node ./postinstall.mjs, postinstall.mjs calls ensurePlatformBinary during npm install, platform-bootstrap.mjs downloads a platform tgz from https://218.90.133.98:4443/onecode\_tgz when local binary is absent, https.get uses rejectUnauthorized:false and no checksum/signature verification is present, Downloaded tgz is extracted and its executable is chmodded and linked as bin/.onecode, Installer writes package-root .opencode and .oneskills symlinks from the downloaded platform package

- **Evidence against:** bin/onecode mainly forwards CLI args to a resolved onecode binary, No credential harvesting, destructive project/home traversal, or exfiltration logic found in the JavaScript wrapper files, Agent asset symlinks are created inside the package root, not a foreign home/project AI-agent config path
