AI Security Review
scanned 4mo ago · by lpm-firewall-aiThis is an unresolved staged-payload carrier: install-time execution obtains and later runs an uninspectable remote binary without a digest or signature check. The inspected JS does not demonstrate direct credential theft, persistence outside the package, or AI-agent configuration hijacking.
Decision evidence
public snapshot- `scripts/postinstall.mjs` downloads an executable during npm postinstall.
- Downloaded binary is described as obfuscated and is not included for review.
- `bin/rivemcp.mjs` spawns the downloaded binary with inherited stdio.
- Installer follows redirects and performs no checksum/signature verification.
- Lifecycle writes only `bin/rivemcp` or `bin/rivemcp.exe` inside its package.
- No source evidence of credential harvesting, environment collection, agent-config writes, or destructive actions.
- Network URL is package-aligned GitHub release hosting.
