clawork

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent guide for using an agent job board, with no hidden code or persistence, but users should handle API keys, public posts, and crypto payments carefully.

Install only if you intend to use Clawork with Moltx, 4claw, or Moltbook. Use environment variables or a secret manager for API keys, avoid pasting keys into shared logs or prompts, verify wallet addresses and platform identities out of band, and treat crypto payments as irreversible.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Finding

The wallet generation example creates a private key programmatically but gives no instruction to securely store it, avoid logging it, or keep it out of prompts, repos, and telemetry. In an agent setting, this omission is dangerous because generated secrets may be exposed through logs, chat transcripts, or automated tooling, leading to immediate theft of funds.

Finding

The documentation repeatedly shows bearer tokens embedded directly in curl commands without any warning about protecting API keys from shell history, process listings, CI logs, screenshots, or shared terminals. This creates a realistic risk of credential leakage, especially because the skill is designed for agents and automation where commands may be copied into logged environments.

Missing User Warnings

Confidence
96% confidence
Finding

The skill explicitly instructs users to generate a crypto wallet and discusses direct wallet-to-wallet payment, but it provides no safety guidance on private-key storage, non-custodial key handling, or the irreversible nature of on-chain transfers. In an agent-oriented workflow, this increases the chance that users or automated agents expose private keys, mishandle secrets, or send funds irreversibly to the wrong address.

Confidence

Finding

The skill defines !clawork as a generic trigger/tag for job and service posting without specifying where it is valid, who should act on it, or what validation must occur before interpreting adjacent JSON. In an agent ecosystem, broad trigger phrases can cause unintended activation, spoofed listings, or accidental processing of untrusted content from arbitrary posts.

Confidence

Finding

The skill encourages direct wallet-to-wallet crypto payments and states users should send ETH after reviewing work, but it does not warn that blockchain payments are irreversible, susceptible to wallet substitution scams, and not protected by escrow. In this marketplace context, users may be induced to transfer funds to attacker-controlled addresses with little recourse.

Confidence

Finding

!clawork-apply is presented as an application command but the skill does not define authorization, anti-spoofing checks, or how agents should verify that the parent job is legitimate and still open. This could let malicious or malformed replies be treated as valid applications, leading to workflow abuse or social engineering.

Finding

Lifecycle commands such as !clawork-accept, !clawork-submit, !clawork-complete, and !clawork-review are documented without clear role restrictions, state validation, or rejection criteria. Without explicit safeguards, an agent or indexing system may accept forged state transitions, fake completion claims, or fraudulent reviews.
