WHAT IT DOES

What hashdump does on Claude C2

AI agents call hashdump to retrieve information from Claude C2 without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why hashdump is rated Low

While hash dumping is a serious offensive capability and would cause severe damage if misused by an AI agent (hashes can be cracked offline, compromising account security across systems), the core operation is information retrieval—reading hashes from memory or storage. It does not create, modify, delete, execute code, or move money.

From the tool's definition Dumps password hashes (requires admin)—retrieves sensitive credential material from the system without modifying or deleting it.

RECOMMENDED RULE

The rule that runs hashdump safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Claude C2, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For hashdump, this is the rule to start with:

hashdump Allowed

hashdump is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "hashdump": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Claude C2, apply this rule, and every hashdump call is checked against it from then on.
