The Infected Chaos Monkey is a security tool which tests your Data Center's ability to withstand perimeter breaches and internal server infection. It uses various methods to propagate through a data center, and reports its success to a centralized C&C server.
Features include:
* Multiple propagation techniques:
* Predefined passwords
* Common exploits
* Multiple propagation protocols:
* SSH
* SMB
* RDP
* A C&C server with a dedicated UI to visualize the Monkey's progress inside the data center
Getting Started
---------------
The Infected Chaos Monkey is comprised of two parts: the Monkey and the C&C server.
The monkey is the tool which infects other machines and propagates to them, while the C&C server collects all Monkey reports and displays them to the user.
1. By default, the monkey uses a local configuration file (usually, config.bin). This configuration file must include the address of the Monkey's C&C server.
2. After successfully connecting to the C&C server, the monkey downloads a new configuration from the server and discards the local configuration. It is possible to change the default configuration from the C&C server's UI.
Both configuration options use a JSON format for specifying options; see "Options" below for details.
Running the C&C Server is as simple as installing our infected monkey debian package on a specific server. The initial infected machine doesn not require a direct link to this server.
Download the latest Monkey binary from <> (alternatively, build it by yourself by following the instructions below).
The download includes executables for various operating systems, and a default configuration file (config.bin).
You can edit the configuration file according the the options detailed below; the default configuration assumes <WHAT?>.
Once downloaded, run the monkey using ```./monkey-linux-64 m0nk3y -c config.bin```
Command line options include:
*`-c`, `--config`: set configuration file. JSON file with configuration values, will override compiled configuration.
*`-p`, `--parent`: set monkey’s parent uuid, allows better recognition of exploited monkeys in c&c
*`-t`, `--tunnel`: ip:port, set default tunnel for monkey when connecting to c&c.
Monkey Modus Operandi
---------------------
1. Wakeup connection to c&c, sends basic info of the current machine and the configuration the monkey uses to the c&c.
1. First try direct connection to c&c.
2. If direct connection fails, try connection through a tunnel, a tunnel is found according to specified parameter (the default tunnel) or by sending a multicast query and waiting for another monkey to answer.
3. If no connection can be made to c&c, continue without it.
2. If a firewall app is running on the machine (supports Windows Firewall for Win XP and Windows Advanced Firewall for Win 7+), try to add a rule to allow all our traffic.
3. Startup of tunnel for other monkeys (if connection to c&c works).
1. firewall is checked to allow listening sockets (if we failed to add a rule to windows firewall for example, the tunnel will not be created)
2. will answer multicast requests from other monkeys in search of a tunnel.
4. Running exploitation sessions, will run x sessions according to configuration:
1. Connect to c&c and get the latest configuration
2. Scan ip ranges according to configuration.
3. Try fingerprinting each host that answer, using the classes defined in the configuration (SMBFinger, SSHFinger, etc)
4. Try exploitation on each host found, for each exploit class in configuration:
1. check exploit class supports target host (can be disabled by configuration)
2. each exploitation class will use the data acquired in fingerprinting, or during the exploit, to find the suitable monkey executable for the host from the c&c.
1. If c&c connection fails, and the source monkey’s executable is suitable, we use it.
2. If a suitable executable isn’t found, exploitation will fail.
3. Executables are cached in memory.
5. will skip hosts that are already exploited in next run
6. will skip hosts that failed during exploitation in next run (can be disabled by configuration)
5. Close tunnel before exiting
Wait for monkeys using the tunnel to unregister for it
Cleanup
Remove firewall rules if added
