## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

The package declares native/solver.c as the source of a small C minimax solver and advertises vendor/solver-\<platform\>-\<arch\> as its compiled output. The darwin-arm64 slot contains a ~34KB Mach-O consistent with that C source, but vendor/solver-darwin-x64 and vendor/solver-linux-x64 are identical 33,648,788-byte Linux ELF Go binaries (same sha256 05b69666...4420) that link net/http, os/exec, crypto/chacha8, and reference /proc/self/. The postinstall script invokes spawnSync(BINARY, \['selftest'\]) on install, so on Linux x64 hosts the shipped opaque Go binary runs automatically at install time. The binary's linked packages (network client, process execution, symmetric crypto) and ~1000x size inflation over any plausible build of the declared C algorithm are inconsistent with the documented purpose, and the darwin-x64 slot being populated with a Linux ELF further indicates the vendor tree was not built from the shipped C source. The install-time execution path against unverified, purpose-mismatched bytes on Linux x64 is a fetch-and-execute equivalent embedded in the tarball rather than downloaded, and the destination of any network activity performed by the Go binary cannot be determined from strings alone.
