I need bug-fix and new feature for dnscat2-powershell script.
Bugs I've found:
1) When you send russian(cyrillic) text in command then script send tons of request and don't work properly (client).
2) When you send kill command then script does not go down(powershelgl-client still sending requests).
3) When you stop the server and restart dnscat2-server then Client does not work properly but still sending requests (you can see tcpdump or error log).
One of the way to solve the problem #3 is to restart the self-session on Client-side each 15 minutes and create new session.
New feature I need:
Also I need a function which will check DNS TXT record for STOP command.
Sometimes client/server not work properly.
I need some stuff which will check every 1 minute value of DNS TXT record of domain I've selected.
The new parameter name should be "-StopDomain".
When I send command with text "!show_info" in server-window then client should send information with information about StopDomain.
This value should contains random subdomain of "-StopDomain".
For example:
I've run dnscat2 in powershell:
dnscat2 -Domain [login to view URL] -e [login to view URL] -StopDomain [login to view URL]
Then I receive new session on the Server side (at the [login to view URL]).
I send a command "!show_info" to my session.
And receive something like this: "StopDomain is: [login to view URL]".
Then something goes wrong and I lost control of the session. (for example server rebooted).
Then I go to DNS settings of [login to view URL] and change value of the TXT-record "xha73" and set it's value to "stop".
Then our powershell-script checking the value of TXT-record [login to view URL] and exit from function and stop sending requests.
Here is this powershell script:
[login to view URL]
Here is dnscat2 server:
[login to view URL]
The best OS to setup dnscat2-server is Ubuntu.
I can give you VPS with dnscat2-server installed.
I can show each problem on my dnscat2-server using TeamViewer before you will start the project.
