AI Security Review

scanned 1mo ago · by lpm-firewall-ai

Automatic destructive install-time mutation is confirmed, but its global-install guard and the absence of confirmed exfiltration do not establish malicious intent. Incomplete inspection coverage of bundled artifacts leaves a real unresolved risk.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm postinstall during a global installation; separately, an explicit `login <code>` command.

Impact

The installer can remove runtime dependencies from its global installation. The opaque bundled code prevents a clean classification, but no concrete exfiltration path was confirmed.

Mechanism

Global-install dependency pruning and user-invoked credential persistence.

AI rationale

Evidence

package.jsonscripts/prune-codex-runtime-binary.mjsdist/cli/index.mjs

Decision evidence

public snapshot

AI called this Suspicious at 72.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package automatically runs three postinstall scripts.
A postinstall script recursively deletes resolved OpenAI Codex platform package directories during global installation.
The CLI accepts a connect code, exchanges it with a server, and persists the returned credentials.
The main bundle and bundled Kimi SDK are very large, and the main bundle contains a NUL byte, limiting reliable static coverage.

Evidence against

The deletion path is guarded to global installs and is skipped for ordinary local installs.
Credential storage occurs in the explicit `login <code>` command, not during installation.
No runtime dependency on first-tree-staging itself is declared.
No confirmed credential exfiltration or unconsented AI-agent configuration write was found in the inspected paths.
