DNSteal : DNS Exfiltration Tool For Stealthily Sending Files Over DNS Requests

DNSteal is a fake DNS server that allows you to stealthily extract files from a victim machine through DNS requests. Below are a couple of different images showing examples of multiple file transfer and single verbose file transfer:

  • Support for multiple files
  • Gzip compression supported
  • Now supports the customisation of subdomains and bytes per subdomain and the length of filename

See help below:

If you do not understand the help, then just use the program with default options!

python dnsteal.py 127.0.0.1 -z -v

This one would send 45 bytes per subdomain, of which there are 4 in the query. 15 bytes reserved for filename at the end.

python dnsteal.py 127.0.0.1 -z -v -b 45 -s 4 -f 15

This one would leave no space for filename.

python dnsteal.py 127.0.0.1 -z -v -b 63 -s 4 -f 0
