The package launcher executes that payload. - **Trigger:** Installing the package runs postinstall; invoking onecode runs the installed binary. - **Impact:** A network attacker or the remote host can supply native code that is installed into the consumer dependency tree and later executed. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs, bin/onecode - **Review source:** ai\_review - **Reviewed:** 2026-09-04T03:13:02.366Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** TLS-bypassed remote native archive download, extraction, and binary launch. - **Attack narrative:** On npm installation, postinstall calls the bootstrap. The bootstrap constructs a URL under a fixed IP address, disables TLS certificate validation, downloads a tar archive, extracts it with tar, moves it into node\_modules, and marks its binary executable. The package then links that binary into bin/.onecode, and the CLI launcher executes the resolved binary. This creates an automatic remote native-code delivery path without integrity verification. - **Rationale:** This package has an automatic install-time chain that retrieves and installs an opaque native executable from a fixed endpoint while disabling TLS verification. The launcher executes the delivered binary, so the behavior is a concrete install-hook payload delivery risk. - **Files touched:** postinstall.mjs, platform-bootstrap.mjs, bin/onecode, node\_modules/onecode-linux-x64, bin/.onecode, .platform-version, .platform-bootstrap-work - **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 postinstall hook automatically runs the bootstrap during npm installation., The bootstrap downloads a native archive from a fixed IP address with TLS certificate verification disabled., The archive is extracted and its executable is installed into node\_modules and linked as bin/.onecode., The launcher later executes the installed native binary. - **Evidence against:** The JavaScript source does not directly harvest credentials or send local data., File mutations shown in source are scoped to the package installation directory. ## Public findings ### 1.
