The downloaded payload is extracted and installed as the package CLI binary. - **Trigger:** npm install postinstall lifecycle when platform package is missing - **Impact:** A remote server can supply executable code that becomes the onecode CLI without registry-published source or integrity protection. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs, bin/onecode - **Review source:** ai\_review - **Reviewed:** 2026-07-04T23:25:50.150Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time unverified remote binary download and staging - **Attack narrative:** During npm install, the postinstall script imports platform-bootstrap.mjs and ensures a platform binary exists. If not found locally, it constructs a tgz URL under a hardcoded IP host, downloads it with certificate verification disabled, extracts it with tar, chmods the binary, and links/copies it to bin/.onecode. That stages opaque executable code outside npm registry integrity guarantees. - **Rationale:** The source establishes a concrete install-time remote payload path with disabled TLS verification and no integrity check. Even without credential theft or immediate binary execution, this is a blockable staged executable payload carrier. - **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:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall: node ./postinstall.mjs, postinstall.mjs calls ensurePlatformBinary() during npm lifecycle, platform-bootstrap.mjs downloads a platform tgz from https://218.90.133.98:4443/onecode\_tgz when local binary is absent, downloadFile() uses https.get with rejectUnauthorized:false and no integrity/signature verification, downloaded tgz is extracted with execSync tar and linked/copied to bin/.onecode for later execution - **Evidence against:** No credential/env/file harvesting logic found in inspected JS files, No install-time execution of the downloaded onecode binary observed; execution occurs via the onecode bin wrapper, Filesystem writes are mostly under the package root/node\_modules, not user home or shell startup files ## Public findings ### 1.
