AI Security Review

scanned 3mo ago · by lpm-firewall-ai

This is an explicit installer with dangerous capability and persistent agent permission changes, warranting a warning. The source does not establish malicious behavior under the stated decision boundary.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

User runs create-sitedesk-code.

Impact

Remote installer compromise or the configured agent can affect the installed host without normal Claude permission prompts.

Mechanism

Privileged bootstrap plus first-party Claude configuration and plugin installation.

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 94.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

dist/index.js executes multiple privileged curl-piped installers when its CLI runs.
dist/permissions-seed.js writes Claude defaultMode=bypassPermissions.
dist/index.js marks the user home workspace trusted and installs Claude plugins at user scope.
payload/platform/config/brand.json embeds an OAuth client secret.

Evidence against

package.json has no preinstall, install, or postinstall hook.
The destructive, network, and privilege actions are reached only through the explicit bin command.
Claude configuration is scoped to ~/.sitedesk-code/.claude, not the default ~/.claude.
No source evidence of secret harvesting or exfiltration was found in the inspected installer paths.
