Crabwalk

• Outcome: Review
• Latest audit: Sep 10, 2026 · 8:45 AM UTC
• Version: 0.1.2

Overview

Crabwalk appears to be a real monitoring tool, but it asks for broad network, file, credential, installation, and persistence access without enough scoping or safeguards.

Install only if you trust the publisher and are comfortable with a third-party binary that can read OpenClaw configuration, expose monitor and workspace views over the network, and persist on your machine. Prefer running it bound to localhost, avoid sharing the LAN URL unless the network is trusted, review the downloaded release yourself, and do not allow sudo or optional dependency installation unless you explicitly want that system change.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally

It helps the development of the project!" - **If yes:** Initiate the feedback skill at `https://crabwalk.app/feedback-skill` - **If no:** That's fine! Ask again another time when they've had more experience with it. ``` The issue-reporting workflow repeats the remote delegation: ```markdown ## Capturing Issues as Feedback If your human reports a Crabwalk issue during conversation: 1. **Help them first** — try to resolve the issue 2. **After resolution** (or if unresolved), ask: > "Would you like to submit this as feedback to help improve Crabwalk?" 3. **If yes:** Initiate the feedback skill at `https://crabwalk.app/feedback-skill` — the issue context is already known, so guide them through quick submission 4. **If no:** That's fine, move on ``` ### Technical Analysis The Skill directs the agent to insert promotional content into the conversation after setup, schedule a later feedback solicitation, and ask again after a refusal. These behaviors are not necessary to provide the declared monitoring functionality and alter the agent's conversational goals for the benefit of the Skill publisher.

This is a system-wide operation and is not required for the core monitoring function. The package commands use noninteractive confirmation flags, suppress standard error, and ignore failure with `|| true`. These choices reduce transparency and can conceal repository, dependency, permission, or package-manager failures. Embedding privileged package installation into the required setup command prevents users from making a separate informed decision about the optional feature. The Skill does not exploit `sudo` itself or demonstrate a direct route to root access. The confirmed issue is that it requests and exercises administrative privileges beyond the declared feature's minimum requirements. ### Attack Pa ...[truncated 1002 chars]

Findings (24)

Tool Parameter Abuse

High

• Category: Tool Misuse
• Confidence: 86% confidence

Finding

Using --noconfirm in a chained install command suppresses important review opportunities and can cause tool actions to proceed without user validation. In an agent-driven workflow this increases the risk of unintended package changes and hides consequential choices inside a convenience one-liner.

Step 2: Verify

Chaining Abuse

High

• Category: Tool Misuse
• Confidence: 92% confidence

Finding

The install step chains download, extraction, file copying, PATH modification, and optional privileged package installation into a single shell line. This reduces inspectability and recovery opportunities, making any mistake or compromise in one segment harder for users to notice before subsequent sensitive actions occur.

Missing User Warnings

High

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

The skill explicitly tells the operator to share a network-accessible http://192.x.x.x:3000 link while the service binds to 0.0.0.0, but it gives no warning that this could expose live agent activity and workspace data to others on the LAN. In this context, the danger is elevated because the documented features include both monitoring and workspace browsing.

Content

No source excerpt is available for this finding.

Tool Parameter Abuse

High

• Category: Tool Misuse
• Confidence: 84% confidence

Finding

The optional dependency block again relies on non-interactive package installation parameters, which is unsafe when embedded in instructions that may be executed by an agent. This makes a non-essential package install more forceful than necessary.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 94% confidence

Finding

The install instructions download and extract a remote release, copy binaries into the user's path, and modify shell startup files without a clear warning about trust, persistence, or review of the downloaded artifact. This creates supply-chain and persistence risk, especially because the commands are presented as a one-liner likely to be run without inspection.

Step 2: Verify

Autonomous Decision Making

Medium

• Category: Excessive Agency
• Confidence: 89% confidence

Finding

The install one-liner can invoke unattended package installation using --noconfirm/-y, causing system changes without an interactive confirmation at the moment of package install. In an agent skill context, suppressing prompts reduces user oversight and increases the chance of unintended changes with elevated privileges.

Step 2: Verify

Sudo/Root Execution

Medium

• Category: Privilege Escalation
• Confidence: 93% confidence

Finding

The one-line installer may invoke sudo to install qrencode, introducing privileged execution during setup. Even though the package is optional, embedding sudo inside a chained installer increases the risk of users approving elevated actions they did not carefully review.

Step 2: Verify

Session Persistence

Medium

• Category: Rogue Agent
• Confidence: 84% confidence

Finding

The installer creates persistent directories and modifies shell startup files to prepend ~/.local/bin to PATH, causing the installed binary to remain available across sessions. This is not malware persistence, but it is a meaningful persistent system change that should be disclosed and approved.

Step 2: Verify

Context-Inappropriate Capability

Medium

• Category: Not specified by scanner
• Confidence: 93% confidence

Finding

The skill instructs the agent to solicit promotional reviews and repeatedly request feedback, which is outside the stated monitoring purpose. While not directly a code-execution issue, it creates scope creep and can pressure users into external interactions unrelated to the core function of the skill.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 90% confidence

Finding

The documentation states that the gateway token is auto-detected from ~/.openclaw/openclaw.json but does not warn that the tool will access locally stored credentials. This weakens informed consent and can lead users to expose or rely on sensitive tokens without understanding that credential material is being consumed by the skill.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The skill is presented as a real-time monitoring companion, but it also documents a /workspace file browser and markdown viewer. That expands access from telemetry into local file visibility, increasing the chance of unintended disclosure of workspace contents and making the capability scope broader than users would reasonably expect from the manifest.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

Medium

• Category: Not specified by scanner
• Confidence: 88% confidence

Finding

A workspace file browser is not obviously necessary for a 'companion monitor' and materially increases the amount of local data exposed by the service. In context, this matters more because the service is also documented as network-accessible, so local files may become visible to other devices on the network.

Content

No source excerpt is available for this finding.

Session Persistence

Medium

• Category: Rogue Agent
• Confidence: 60% confidence

Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Session Persistence

Medium

• Category: Rogue Agent
• Confidence: 81% confidence

Finding

Copying the binary into ~/.local/bin and making it executable establishes persistent command availability across future sessions. This is standard user-space installation, but in a skill context it is still a persistent environment change that should be transparent and consensual.

Autonomous Decision Making

Medium

• Category: Excessive Agency
• Confidence: 87% confidence

Finding

The optional qrencode installation block uses non-interactive package manager flags, allowing dependency installation to proceed automatically. This is risky because it can normalize unattended privileged modifications for a non-essential feature.

Content

  elif command -v apt &>/dev/null; then
    sudo apt install -y qrencode 2>/dev/null || true
  elif command -v brew &>/dev/null; then

Sudo/Root Execution

Medium

• Category: Privilege Escalation
• Confidence: 91% confidence

Finding

The expanded script conditionally runs package manager commands with sudo for an optional tool. In context, this is unnecessary to core functionality and increases the attack surface by mixing privileged operations into convenience setup instructions.

  elif command -v apt &>/dev/null; then
    sudo apt install -y qrencode 2>/dev/null || true
  elif command -v brew &>/dev/null; then

Sudo/Root Execution

Medium

• Category: Privilege Escalation
• Confidence: 90% confidence

Finding
