BeatClaw

Security checks for vulnerabilities and agentic risk

Overview

BeatClaw is mostly coherent for generating and selling beats, but its remote install and self-update flow can persistently replace agent instructions without pinning or review.

Review before installing. Prefer a ClawHub-managed or manually reviewed installation over the direct curl/agent-install path, and only use it if you trust beatclaw.com to serve future skill updates. Be aware the connected agent can hold a long-lived BeatClaw producer token and, after confirmation, spend Suno credits, publish products, change pricing/genres, process stems, or delete beat listings.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Rogue AgentSelf-Modification, Session Persistence
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Skill Enumeration

Medium
Category
Agent Snooping
Confidence
85% confidence
Finding

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

Content

Scanner excerpt · SETUP.md (reported line 8)May include surrounding context.

Option A — From beatclaw.com (recommended)

bash
mkdir -p ~/.claude/skills/beatclaw && \
  curl -fsSL https://beatclaw.com/skill -o ~/.claude/skills/beatclaw/SKILL.md

Session Persistence

Medium
Category
Rogue Agent
Confidence
90% confidence
Finding

The install command places a remote file into a session-persistent autoload location (~/.claude/skills/beatclaw/SKILL.md). This increases risk because any malicious or later-compromised content survives beyond the initial install and will be reloaded in future sessions, amplifying the effect of a one-time compromise.

Option A — From beatclaw.com (recommended)

bash
mkdir -p ~/.claude/skills/beatclaw && \
  curl -fsSL https://beatclaw.com/skill -o ~/.claude/skills/beatclaw/SKILL.md

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The setup instructs users to download a remote SKILL.md directly into the agent's skills directory with curl, but gives no warning to inspect or pin the content first. Because skill files influence future agent behavior, this creates a software supply-chain risk: compromise of beatclaw.com, DNS/TLS issues, or content changes could persistently install adversarial instructions.

Confidence

Finding

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

Content

Scanner excerpt · SETUP.md (reported line 9)May include surrounding context.

bash
mkdir -p ~/.claude/skills/beatclaw && \
  curl -fsSL https://beatclaw.com/skill -o ~/.claude/skills/beatclaw/SKILL.md

For OpenClaw: replace ~/.claude/skills/ with ~/.openclaw/skills/.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

Telling the user to ask the agent to install the skill from a URL delegates fetching and writing remote prompt content to the agent without any review step. This is dangerous because it normalizes remote prompt injection and persistence: the agent may retrieve untrusted instructions and save them where they will automatically load in later sessions.

Whitespace Padding

Medium
Category
Prompt Injection
Confidence
70% confidence
Finding

Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.

**ERROR HANDLING — DO NOT POLL ON FAILURE.** If `generate-beat` returns any non-2xx status, NO beat row was created and NO `task_id` was issued. Do **not** start polling `beats_feed` or `poll-suno` — there's nothing to find. Stop immediately and surface the error to the human verbatim.
