| description | Complete user guide for the IoM (Implant-over-Middleware) C2 framework. Covers architecture concepts, basic operations, startup parameters, authentication configuration, troubleshooting, documentation resources, and community feedback. Trigger conditions: use this skill when the user asks about how IoM works, command usage, architecture concepts, configuration methods, how to troubleshoot issues, where to find documentation, or how to file an issue. Should also trigger for questions like "how do I connect", "what is a session", "I got an error", or "is there documentation".

Core Concepts
See reference/concepts.md for detailed explanations.
| Concept | Summary |
|---|
| Session | An active implant connection containing target system info, a task queue, and module capabilities |
| Listener | A network service that accepts implant connections and manages multiple pipelines |
| Pipeline | A transport channel under a listener, responsible for encryption, protocol parsing, and frame handling |
| Task | An execution unit sent to the implant, with status tracking and timeout control |
| Module | A capability category declared by the implant, determining which commands are available |
| Event | A real-time notification (new session, task completion, session offline, etc.) |
Quick Start
Starting the Client
iom login server.auth
Client startup parameters:
| Parameter | Description |
|---|
--mcp <addr> | Enable MCP server (e.g., 127.0.0.1:5005) |
--rpc <addr> | Enable LocalRPC gRPC server |
--daemon | Daemon mode โ run in background without interactive terminal |
--tui | TUI multiplexing mode (split-pane terminal) |
--quiet | Quiet mode โ suppress startup event output |
Authentication and Configuration
The .auth file contains mTLS certificates and the server address. It serves as the credential for connecting to the server.
Configuration directory structure (see reference/config.md for details):
~/.config/malice/
โโโ malice.yaml # Client configuration (MCP, RPC, logging, etc.)
โโโ configs/ # .auth file storage (auto-migrated after login)
โโโ log/ # Log files
โโโ resources/ # Resource files
โโโ temp/ # Temporary files
Basic Operations
Session Management
session # List active sessions
session --all # List all sessions (including offline)
use <session_id> # Enter a session context (supports ID prefix matching)
background # Exit the current session and return to the main menu
Common Commands Within a Session
sysinfo # System information
whoami # Current user
privs # Current privileges
ps # Process list
ls / cd / pwd / cat # File system operations
upload <local> <remote> # Upload a file
download <remote> # Download a file
shell <command> # Execute a shell command
Infrastructure Management
listener # List listeners
pipeline list # List pipelines
pipeline tcp --name <n> --host <h> --port <p> # Create a TCP pipeline
Task Management
tasks # List tasks
tasks --task-id <id> # View task details
tasks cancel --task-id <id> # Cancel a task
Module Management
modules list # View available modules
modules refresh # Refresh modules from the implant
modules load <addon> # Load an extension module
Command Categories
IoM commands are organized by function. See reference/commands.md for the full reference.
| Category | Description | Examples |
|---|
| Basic | Info, heartbeat, binding | sysinfo, sleep, suicide |
| Execution | Run programs and code | shell, execute_exe, execute_assembly, bof |
| File System | Browse and manipulate files | ls, cd, cat, rm, mkdir, cp, mv |
| File Transfer | Upload and download | upload, download |
| System | System operations | ps, kill, env, netstat, whoami |
| Privileges | Privilege management | privs, getsystem, runas, rev2self |
| Network | Proxying and forwarding | proxy, forward, reverse |
| Enumeration | Environment discovery | enum av, enum software, enum dc |
MAL Plugins
IoM extends its command capabilities through MAL (a Lua plugin system). The built-in community plugin package provides 90+ commands covering enumeration, privilege escalation, credential harvesting, lateral movement, persistence, and more.
mal list # List installed plugins
mal install <name> # Install from the community repository
mal remove <name> # Uninstall
search_commands("keyword") # Search for plugin-provided commands
See reference/mal-usage.md for MAL usage details.
See reference/builtin-plugins.md for the full built-in command list.
MCP Tool Interface
The IoM client provides an MCP server that exposes the following tools:
| Tool | Purpose |
|---|
search_commands | Fuzzy-search commands by name/description, returns lightweight summaries |
execute_command | Execute any client command, automatically waits for the task result |
execute_lua | Execute a Lua script (with access to all IoM internal APIs) |
get_history | Retrieve output from historical tasks |
Recommended workflow (progressive discovery):
search_commands("keyword") โ search for related commandsexecute_command("<cmd> --help") โ view specific usageexecute_command("<cmd> <args>") โ execute the command
Lua Script Execution
Use execute_lua to run Lua scripts directly for automation and batch operations:
execute_lua('return string.format("2+2=%d", 2+2)')
execute_lua('local s = active(); return s.Os.Hostname', session_id="abc123")
See reference/lua-scripting.md for details.
Troubleshooting
See reference/troubleshooting.md for common issues, covering:
- Connection failures (auth files, certificates, network)
- Session anomalies (offline, heartbeat timeout, unavailable modules)
- Task issues (stuck, timed out, no output)
- Debugging methods (log directory, audit log level)
