AI Security Review

scanned 4mo ago · by lpm-firewall-ai

Source inspection confirms unconsented npm postinstall mutation of a broad Claude/AI-agent control surface, which meets the firewall block policy even without observed exfiltration. The behavior is package-aligned safety tooling, but it is activated by lifecycle install rather than an explicit user setup command. Product guard normalized a concrete AI-agent control hijack publish_block to the blockable dangerous-capability shape.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm install of yana-ai@0.43.1 with lifecycle scripts enabled

Impact

Claude Code or related agent sessions in the project may execute package-supplied hooks and instructions after install, changing agent behavior without an explicit setup command.

Mechanism

postinstall copies package-supplied AI-agent hook/control files into target project

Policy narrative

On install, npm runs the package postinstall script with --auto. The installer resolves the target from INIT_CWD or cwd, then recursively copies package-owned hooks, commands, agents, rules, scripts, and gates into the consuming project's .claude directories plus .claude-plugin metadata. The shipped hook manifest wires Claude hook events to those package-supplied shell commands, creating an automatic AI-agent control-surface mutation at install time.

Decision evidence

public snapshot

AI identified this as a dangerous AI-agent capability at 93.0% confidence with low false-positive risk.

Evidence for policy risk

package.json defines postinstall: node scripts/npm-install.js --auto
scripts/npm-install.js uses INIT_CWD/process.cwd as TARGET project root
postinstall copies core/hooks, commands, agents, rules, scripts, gates into TARGET .claude/*
postinstall also writes .claude-plugin/plugin.json and marketplace.json
copied .claude-plugin/hooks/hooks.json wires Claude hooks to package shell commands

Evidence against

No credential harvesting or external exfiltration found in inspected install script
core/hooks/telemetry-sender.sh writes local .claude/state/telemetry.jsonl only
scripts/yana-rt-wrapper.js only execFileSyncs explicit/system/package runtime candidates
No large hidden binary payloads found by size scan
