A later onecode invocation executes that staged binary. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 94.0% - **Started:** 2026-08-11T05:29:40.982Z - **Finished:** 2026-08-11T05:30:22.117Z - **Download time:** 516 ms - **Static scan time:** 41 ms - **AI review time:** 40577 ms - **Total time:** 41135 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall fetches an unverified remote native payload, extracts it, and stages it as the CLI binary. A later onecode invocation executes that staged binary. - **Trigger:** npm install, followed by invoking onecode - **Impact:** A compromised or substituted download can yield arbitrary code execution when the CLI is run. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs, bin/onecode - **Review source:** ai\_review - **Reviewed:** 2026-08-11T05:30:22.117Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** TLS-bypassed remote native payload download and launcher execution - **Rationale:** This is a concrete unsafe staged-payload delivery chain, but inspected JavaScript does not itself show exfiltration, destructive activity, or foreign AI-agent control-surface mutation. It warrants a warning rather than a publish block under the stated policy. - **Files touched:** package.json, postinstall.mjs, platform-bootstrap.mjs, bin/.onecode, node\_modules/onecode-\-\, node\_modules/onecode-\-\/bin/onecode, .platform-bootstrap-work, .platform-version, .opencode, .oneskills - **Network endpoints:** https://218.90.133.98:4443/onecode\_tgz ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall.mjs on npm install., platform-bootstrap.mjs downloads a native tgz from a raw-IP HTTPS endpoint., Download disables TLS certificate validation and has no hash/signature verification., postinstall extracts the downloaded archive into node\_modules and makes its binary executable., The launcher later executes the installed binary and mirrors .opencode/.oneskills assets. - **Evidence against:** No source reads credentials or harvests user files., No source sends local data to the endpoint., Writes and symlinks are confined to this package and its node\_modules subtree. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node ./postinstall.mjs ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review.

High: Unverified Remote Native Payload Install - **Category:** Source - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() Install-time source downloads a native archive from a fixed external host without transport verification, extracts it, and installs an executable payload. Public source snippet (untrusted): ```json scripts.postinstall = node ./postinstall.mjs Install-time code downloads an unverified remote native archive, stages it locally, activates an executable path, and exposes it to process execution.
