The archive is extracted into node\_modules, exposes an executable, and supplies hidden agent-related asset directories. - **Trigger:** npm postinstall during package installation; the fetched executable runs when the onecode command is invoked. - **Impact:** A network attacker or the remote host can provide a native payload that is later executed by the installed command and can supply agent-related assets. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-01T01:14:54.139Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unverified remote native payload download, extraction, and hidden asset symlinking. - **Attack narrative:** npm runs postinstall, which calls the bootstrap. The bootstrap constructs a URL at a fixed IP, disables certificate verification, downloads and extracts a platform archive, then installs an executable and symlinks hidden .opencode and .oneskills directories from that archive into the launcher. The visible command executes the installed native binary when invoked. This makes the remote archive an unverified code and asset source in the installation path. - **Rationale:** The package automatically installs an opaque native payload from a fixed IP with TLS verification disabled and makes it executable. Its postinstall also wires hidden agent-related assets from that payload into the package root. - **Files touched:** postinstall.mjs, platform-bootstrap.mjs, bin/.onecode, .platform-version, .platform-bootstrap-work, node\_modules/onecode-linux-x64, .opencode, .oneskills - **Network endpoints:** https://218.90.133.98:4443/onecode\_tgz ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** A postinstall hook automatically invokes the platform bootstrap., The bootstrap downloads a versioned native archive from a hard-coded IP address while disabling TLS certificate verification., It extracts the downloaded archive and marks its included binary executable., The installer replaces hidden .opencode and .oneskills entries in the package with symlinks to payload-supplied assets. - **Evidence against:** The visible launcher only forwards user arguments to the resolved platform binary., No credential collection or explicit exfiltration appears in the inspected JavaScript sources. ## Public findings ### 1.
