AI Security Review

scanned 2h ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. An explicit login/global-install configures SolonGate hooks for every Claude Code session and can add a shell wrapper. The guard subsequently retrieves policy, audit logs, and newer hook bundles from SolonGate Cloud.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

User runs the package's `login` flow or global installer, then starts Claude Code.

Impact

Remote service-controlled hook updates can alter behavior across Claude Code sessions after opt-in.

Mechanism

Global AI-agent hook installation with remote hook self-update and audit telemetry.

Rationale

Source inspection confirms an explicit first-party global Claude Code extension with remote self-updating hooks and telemetry, creating meaningful lifecycle risk. No install-time activation, unrelated endpoint, or concrete covert malicious chain was found.

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

`dist/global-install.js` overwrites `~/.claude/settings.json` with global PreToolUse/PostToolUse/Stop hooks.
`hooks/guard.mjs` downloads newer hook code from the cloud and atomically replaces installed hook files.
Installed audit/guard hooks send tool arguments and decisions to the configured SolonGate API.
Optional OS-lock commands can make hook/config/settings files immutable.

Evidence against

`package.json` has no preinstall/install/postinstall lifecycle hook.
Global hook setup occurs through explicit `login`/global-install CLI flow and accepts a user API key.
Observed network hosts are package-aligned SolonGate endpoints; no unrelated credential-exfiltration endpoint found.
Child-process use launches the explicit shield target or refreshes the package's own hook.
