GuavaGuard 🛡️ — Part of the guard-scanner Ecosystem

Runtime security scanner and monitor for your OpenClaw agent.

🔗 Looking for full static scanning? → clawhub install guard-scanner (150+ patterns, 23 categories, 4,000+ downloads)

GuavaGuard watches tool calls in real-time and warns when it detects dangerous patterns — reverse shells, credential exfiltration, sandbox escapes, and more.

Quick Start

# 1. Install the full security scanner suite
clawhub install guard-scanner    # Static scanner (150+ patterns)
clawhub install guava-guard      # Runtime monitor (12 patterns)

# 2. Pre-install safety gate
npx guard-scanner ./skills --self-exclude --verbose

# 3. Enable the runtime hook
openclaw hooks install skills/guava-guard/hooks/guava-guard
openclaw hooks enable guava-guard

# 4. Restart gateway, then verify:
openclaw hooks list   # Should show 🍈 guava-guard as ✓ ready

What It Detects (12 runtime patterns)

Pattern	Severity	Example
Reverse shell	🔴 CRITICAL	/dev/tcp/, nc -e, socat TCP
Credential exfiltration	🔴 CRITICAL	Secrets → webhook.site, ngrok, requestbin
Guardrail disabling	🔴 CRITICAL	exec.approval = off (CVE-2026-25253)
macOS Gatekeeper bypass	🔴 CRITICAL	xattr -d quarantine
ClawHavoc AMOS	🔴 CRITICAL	socifiapp, Atomic Stealer indicators
Base64 → shell	🔴 CRITICAL	base64 -d | bash
Download → shell	🔴 CRITICAL	curl | bash, wget | sh
Cloud metadata SSRF	🔴 CRITICAL	169.254.169.254
Known malicious IP	🔴 CRITICAL	91.92.242.30
DNS exfiltration	🟠 HIGH	nslookup $secret, dig @attacker
SSH key access	🟠 HIGH	.ssh/id_*, .ssh/authorized_keys
Crypto wallet access	🟠 HIGH	wallet seed, mnemonic, seed phrase

The guard-scanner Ecosystem

GuavaGuard is the runtime half of a two-layer defense:

Layer	Tool	Patterns	When
Static	guard-scanner	150+ patterns / 23 categories	Before install
Runtime	guava-guard	12 patterns	During execution

Install both for maximum protection:

clawhub install guard-scanner
clawhub install guava-guard

Current Limitation

Warning: OpenClaw's hook API does not yet support blocking tool execution. GuavaGuard currently warns only — it cannot prevent dangerous calls. When a cancel API is added, blocking will be enabled automatically. See: Issue #18677
