Enumerate local groups
AI agents call inject_net_localGroup to retrieve information from Cobalt Strike MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Enumeration is a read operation that gathers information about system configuration. However, in the context of Cobalt Strike (a red team/penetration testing framework), enumeration by an injected process is assigned 'medium' severity because it aids in lateral movement and privilege escalation reconnaissance, even though the tool itself performs no destructive or write operations.
From the tool's definition Tool name 'inject_net_localGroup' and description 'Enumerate local groups' indicate a reconnaissance/query operation that retrieves information about local groups on a target system without modifying data.
Attacks that exploit this kind of access
Enumerate local groups. It is categorised as a Read tool in the Cobalt Strike MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Cobalt Strike MCP Server MCP server in PolicyLayer and add a rule for inject_net_localGroup: allow, deny, rate-limit, or require approval. 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.
inject_net_localGroup is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the inject_net_localGroup 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.
Set action: deny in the PolicyLayer policy for inject_net_localGroup. 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.
inject_net_localGroup 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.
