The archive is extracted into the consumer's node\_modules and its binary is made executable. - **Trigger:** npm installation runs postinstall. - **Impact:** A network attacker or operator of the fixed endpoint can supply executable code during installation without certificate or integrity verification. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-05T09:35:53.618Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Lifecycle download, extraction, and installation of an unverified native binary. - **Attack narrative:** During npm installation, postinstall calls the bootstrapper. When no local platform binary is present, it fetches a versioned archive from a fixed IP address while disabling TLS certificate validation, extracts it with tar into node\_modules, and marks the resulting binary executable. The package provides no hash, signature, or other integrity validation for that install-time executable payload. - **Rationale:** This is an automatic install-time remote native-code delivery path with certificate validation disabled and no payload integrity check. It creates a concrete supply-chain execution risk independent of the normal user-invoked launcher. - **Files touched:** .platform-bootstrap-work, node\_modules/onecode-linux-x64, bin/.onecode, .platform-version, .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:** The package automatically runs a postinstall script., Postinstall invokes the platform bootstrapper., The bootstrapper downloads an archive from a fixed IP address and disables TLS certificate validation., It extracts the downloaded archive into node\_modules and makes its binary executable. - **Evidence against:** No credential harvesting or data exfiltration was found in the inspected JavaScript source., The launcher only starts the installed platform binary when the user runs the CLI. ## Public findings ### 1.
