Platform-specific CodeM binary for win32-x64-gnu.

AI Security Review

scanned 2h ago · by lpm-firewall-ai

No confirmed malicious install-time or import-time attack surface. Installation only adjusts permissions on the package-owned executable; network and agent features require later binary invocation.

Static reason
One or more suspicious static signals were detected.
Trigger
npm postinstall; separate explicit execution of `codem-core.exe`
Impact
No confirmed credential theft, exfiltration, persistence, destructive action, or AI-agent configuration mutation during installation.
Mechanism
package-owned executable permission normalization
Rationale
Direct inspection shows the sole lifecycle action changes mode on the bundled executable and does not execute it. Native-binary and runtime network/agent strings alone do not establish malicious behavior.
Evidence
package.jsoncodem-core.exe

Decision evidence

public snapshot
AI called this Clean at 89.0% confidence as Benign with low false-positive risk.
Evidence for block
  • `package.json` has a `postinstall` hook.
  • Package ships native `codem-core.exe`.
  • The PE imports networking and process APIs, consistent with a CLI agent binary.
Evidence against
  • `postinstall` only calls `chmodSync` on its own `codem-core.exe` and suppresses errors.
  • No lifecycle hook executes the binary, contacts a network endpoint, or writes user/agent configuration.
  • Package contains only `package.json`, `LICENSE`, and the platform-specific executable.
  • Embedded service URLs and MCP/config strings are runtime CLI capabilities, not install-time behavior.
Behavioral surface
SourceNo risky source behavior triggered.
Supply chainNo supply-chain packaging signals triggered.
