It also replaces package-root agent-related asset paths with links to the downloaded content. - **Trigger:** npm postinstall during package installation - **Impact:** A network attacker or remote host can supply executable and agent-related content that is installed without user action. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-15T02:13:34.442Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** TLS-bypassed remote native payload download, extraction, and agent-asset linking - **Attack narrative:** The npm postinstall hook calls the bootstrapper. On a missing platform binary, it downloads a versioned archive from a fixed IP address with certificate validation disabled, extracts it with tar, moves it into node\_modules, and marks the binary executable. It then removes and recreates .opencode and .oneskills links at the launcher root, causing remotely supplied content to be available to the installed agent. - **Rationale:** This is an automatic install-time remote native payload chain with TLS verification explicitly disabled. The same hook replaces agent-related filesystem paths with content from that unverified archive. - **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 block:** A postinstall hook automatically invokes the bootstrapper., The bootstrapper downloads a platform archive from a fixed IP address while disabling TLS certificate validation., The install hook extracts the unverified archive and makes its contained binary executable., Installation deletes and replaces launcher-root .opencode and .oneskills paths with links to remotely supplied content. - **Evidence against:** The visible JavaScript does not harvest credentials or send local data., The launcher runs the installed binary only when the user invokes the onecode command. ## Affected versions and remediation This report applies to @onescience/onecode@1.14.50-202609151008. - Avoid installing @onescience/onecode@1.14.50-202609151008. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
