# IEC104 Client for Metasploit
## Definition
IEC 60870 part 5 is one of the IEC 60870 set of standards which define systems used for telecontrol (supervisory control and data acquisition) in electrical engineering and power system automation applications. Part 5 provides a communication profile for sending basic telecontrol messages between two systems, which uses permanent directly connected data circuits between the systems. The IEC Technical Committee 57 (Working Group 03) have developed a protocol standard for telecontrol, teleprotection, and associated telecommunications for electric power systems. The result of this work is IEC 60870-5. Five documents specify the base IEC 60870-5:
IEC 60870-5-104 (IEC 104) protocol is an extension of IEC 101 protocol with the changes in transport, network, link & physical layer services to suit the complete network access. The standard uses an open TCP/IP interface to network to have connectivity to the LAN (Local Area Network) and routers with different facility (ISDN, X.25, Frame relay etc.) can be used to connect to the WAN (Wide Area Network). Application layer of IEC 104 is preserved same as that of IEC 101 with some of the data types and facilities not used. There are two separate link layers defined in the standard, which is suitable for data transfer over Ethernet & serial line (PPP - Point-to-Point Protocol). The control field data of IEC104 contains various types of mechanisms for effective handling of network data synchronization.

## Install
Create a new folder for the IEC104 module, place script in new folder
```
mkdir -p $HOME/.msf4/modules/auxiliary/client/iec104
cp iec104.rb $HOME/.msf4/modules/auxiliary/client/iec104/
```
## Usage
### Selection of module in msfconsole
```
msf > use auxiliary/client/iec104/iec104
```
### Show module options
```
msf auxiliary(client/iec104/iec104) > show options
Module options (auxiliary/client/iec104/iec104):
Name Current Setting Required Description
---- --------------- -------- -----------
ASDU_ADDRESS 1 yes Common Address of ASDU
COMMAND_ADDRESS 0 yes Command Address / IOA Address
COMMAND_TYPE 100 yes Command Type

---- -----------
SEND_COMMAND Send command to device
```
### Usage Examples
Example of sending IEC104 general interrogation command
This is using thde default setting for command type, address and value, this is connecting to an local IEC104 server simulator for demo purposes
```

Example sending switching command
IOA address to be switched is "5", the command type is a double command "46", command is for switching off without time value "5"
