## Verdict summary
**Blocked & quarantined** — A network attacker or the remote host can supply code that will be installed and later executed as the user.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Install Hook Abuse
- **Selected version:** 1.14.50-202609111612

## Security analysis

### Published attack-surface review

- **Summary:** Installing the package automatically retrieves an opaque native archive from a fixed IP address without certificate validation. It extracts and enables an executable payload and links downloaded assets into the package root.

- **Trigger:** npm installation runs postinstall.

- **Impact:** A network attacker or the remote host can supply code that will be installed and later executed as the user.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-09-11T08:19:45.816Z

### AI review details

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

- **Mechanism:** Unverified remote native payload download, extraction, and executable installation.

- **Attack narrative:** The package declares a postinstall hook that invokes its bootstrapper. On non-Windows systems, the bootstrapper fetches a versioned archive from a hard-coded IP endpoint with TLS verification disabled, extracts it using tar, moves its contents into node\_modules, and marks the resulting binary executable. The launcher subsequently starts that binary. The archive is not integrity checked, so remote control of the endpoint or its connection controls code installed on the consumer machine.

- **Rationale:** This is an automatic install-time remote code delivery chain with disabled TLS validation and no integrity verification. The downloaded native payload is opaque to the package review and is later executed by the package launcher.

- **Files touched:** postinstall.mjs, platform-bootstrap.mjs, node\_modules/onecode-linux-x64, bin/.onecode, .opencode, .oneskills

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

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The postinstall hook automatically runs the bootstrapper during installation., The bootstrapper downloads a platform archive from a fixed IP address and disables TLS certificate verification., It extracts the unverified archive, places it in node\_modules, and makes its contained executable runnable., Installation also replaces package-root asset paths with symlinks to downloaded content., The install hook invokes the platform bootstrapper using the package root directory.

- **Evidence against:** The inspected JavaScript contains no direct credential collection or outbound data upload., The launcher only resolves and starts the downloaded platform executable.

## Affected versions and remediation

This report applies to @onescience/onecode@1.14.50-202609111612.
