WHAT IT DOES

What inject_hashdump does on Cobalt Strike MCP Server

AI agents invoke inject_hashdump to trigger actions in Cobalt Strike MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why inject_hashdump needs a policy

This tool performs process injection to dump NTLM/password hashes from a system. It is part of a red team C2 framework (Cobalt Strike), and misuse could expose all local/domain credentials. Process injection is an Execute-category action; however, it also has credential-theft implications. Since it runs injected code to extract sensitive data rather than simply reading files, Execute is the most accurate category.

From the tool's definition 'Dump password hashes (inject mode)' — injecting into a process to extract credential hashes is a code execution/process injection operation targeting credential material

Verdict

inject_hashdump Rate-limited

inject_hashdump stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Questions about inject_hashdump

What does the inject_hashdump tool do? +

Dump password hashes (inject mode). It is categorised as a Execute tool in the Cobalt Strike MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on inject_hashdump? +

Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Cobalt Strike MCP Server. Nothing to install.

What risk level is inject_hashdump? +

inject_hashdump is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit inject_hashdump? +

Yes. Add a rate_limit block to the inject_hashdump rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block inject_hashdump completely? +

Set action: deny in the PolicyLayer policy for inject_hashdump. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides inject_hashdump? +

inject_hashdump is provided by the Cobalt Strike MCP Server MCP server (mickeydb/cobalt-strike-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
