Summary
The npm postinstall hook runs ensurePlatformBinary(), which downloads a.tgz archive from the hardcoded bare-IP URL https://218.90.133.98:4443/onecode_tgz/onecode-<ver>/onecode-linux-x64-<ver>.tgz, extracts it via tar -xzf , chmods the extracted file to 0o755, hardlinks it into bin/.onecode, and the shipped CLI launcher invokes it. The HTTPS request explicitly sets rejectUnauthorized: false , disabling TLS certificate verification, and no hash or signature check is performed on the downloaded artifact. The download destination is a bare IPv4 address on a non-standard port, not a publisher-owned domain or a recognized release host. The package name and launcher (@onescience/onecode) mirror the unrelated 'opencode' project — env-var fallbacks reference OPENCODE_BIN_PATH and bundled asset directories are named.opencode/session-seed and.opencode/oneskills — while the executable payload is retrieved from an unrelated hardcoded IP endpoint. Anyone controlling that host, or any on-path network attacker (TLS is disabled), can deliver arbitrary code that executes on every installer's machine.
