The payload is not present in the inspected package, so its behavior cannot be verified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 96.0% - **Started:** 2026-08-14T08:20:52.266Z - **Finished:** 2026-08-14T08:21:48.029Z - **Download time:** 503 ms - **Static scan time:** 58 ms - **AI review time:** 55202 ms - **Total time:** 55763 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall fetches an unverified native archive from a fixed IP address, extracts it, and installs a runnable CLI binary. The payload is not present in the inspected package, so its behavior cannot be verified. - **Trigger:** npm install; subsequently running the onecode CLI - **Impact:** A network attacker or payload host can supply code that becomes the package CLI. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs, bin/onecode - **Review source:** ai\_review - **Reviewed:** 2026-08-14T08:21:48.029Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** insecure remote native payload bootstrap - **Rationale:** This is a real unverified remote-payload install chain, but the inspected source does not itself show exfiltration, destructive behavior, or foreign AI-agent control-surface mutation. It warrants a warning rather than a block under the stated boundary. - **Files touched:** .platform-bootstrap-work, bin/.onecode, .platform-version, .opencode, .oneskills - **Network endpoints:** https://218.90.133.98:4443/onecode\_tgz ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Low - **Evidence for:** postinstall invokes platform setup during npm installation., Bootstrap downloads a versioned archive from a fixed IP endpoint with TLS verification disabled., Downloaded archive is extracted and its native binary is hard-linked into the CLI launcher., CLI executes that installed binary when the user runs onecode. - **Evidence against:** Inspected JavaScript contains no credential harvesting or data-exfiltration logic., Writes and asset symlinks are scoped to this package directory; no foreign agent configuration is directly modified. ## Public findings ### 1.
