It extracts the archive into node\_modules and configures its binary to run when the CLI is invoked. - **Trigger:** Installing @onescience/onecode; invoking onecode executes the staged binary. - **Impact:** The endpoint can supply an arbitrary executable that will run as the installing user on later CLI use. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs, bin/onecode - **Review source:** ai\_review - **Reviewed:** 2026-07-28T08:19:11.505Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall remote binary download, extraction, and launcher linkage - **Attack narrative:** The postinstall hook downloads a platform tgz from a hard-coded IP address while explicitly disabling TLS certificate verification. It neither pins nor verifies the archive, extracts it into node\_modules, and links its executable into bin/.onecode. The CLI launcher then spawns that executable, allowing the remote server to stage arbitrary native code for execution. - **Rationale:** This is a concrete unverified remote payload chain activated by npm postinstall, not merely a normal packaged optional dependency. The fixed IP endpoint and disabled TLS validation make the staged executable attacker-controlled if the endpoint or connection is compromised. - **Files touched:** package.json, postinstall.mjs, platform-bootstrap.mjs, node\_modules/onecode-linux-x64/, bin/.onecode, .platform-version, .platform-bootstrap-work, bin/onecode - **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:** package.json runs postinstall.mjs during npm install., postinstall.mjs invokes ensurePlatformBinary()., platform-bootstrap.mjs downloads a versioned tgz from a fixed IP endpoint., Download disables TLS certificate validation and has no integrity verification., Downloaded archive is extracted into node\_modules and its binary is linked for execution., bin/onecode executes the linked/downloaded binary. - **Evidence against:** No credential harvesting or unrelated file collection was found in the inspected files., No explicit exfiltration endpoint beyond the binary-download host was found. ## Public findings ### 1.
