I have the sever running but get the below error on the Windows client:

Start-Dnscat2EncInit : Failed to negotiate encryption. Ensure your dnscat2 server is set up correctly.
At line:1468 char:40

•     $Session = Start-Dnscat2EncInit <<<<  $Session $False
  

  • CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
  • FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,Start-Dnscat2EncInit

At the moment, encryption functions use BouncyCastle's crypto DLL, which requires a reflective load of a huge amount of data, significantly increasing the script size. This should be avoided, which will require finding alternative Salsa20, SHA3, and ECDH-P256 functions.

Hi mate, the script is amazing, and I was wondering if you have any plans of updating it to support the latest version of DNScat2 with all its new features?.

Cheers.

I just running dnscat2 server and waiting for client.
I used --security=open.

ruby ./dnscat2.rb --security=open mydomain.com

dnscat2> /root/dnscat2/server/libs/dnser.rb:179:in unpack': DNS packet was truncated (or we messed up parsing it)! (DNSer::Packet::FormatException) from /root/dnscat2/server/libs/dnser.rb:209:in block in unpack_name'

After this error dnscat2-server goes down and I should re-run it.
I did not sent a client.

Thanks.

Hi!

Is it possible to make some changes for money?
I can pay you bitcoins for some changes in your powershell script dnscat2-powershell.
I found few bugs:

1. when you send any cyrillic symbol.
2. when you send kill command.

Please send me your email or jabber for more information.

Thanks!

Add documentation and more comments.

When I send any russian text - the dnscat2-powershell does not work properly.

session got terminated after a part of time and when the computer is in idle mode the session got disconnected and error code shown=

CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,Update-Dnscat2Session
on line 2105 and char 41

$Sessions[$SessionId] = Update-Dnscat2Session $Sessions[$SessionId]

The following commands are having issues:

upload /tmp/test C:/test
download C:/test /tmp/test

For download, dnscat2 says that it is expecting more bytes and fails to write the file, or the file is written but is missing a few bytes at the end. For upload, sometimes it works, and sometimes nothing happens.

Looking into this.
