Wow, dnscat2-powershell actually works!? It was written a few versions ago,
didn't realize it was still working. :)

It sounds like after the connection ended, something kept on sending MSG
packets, which are standard data packets. That could be recursive DNS
servers that haven't realized it's over yet, or it could be that the client
doesn't realize it shut down.

I suspect it's not a big deal, unless this broke something - it just sounds
like the client sent a terminator packet then kept sending MSG.

If this is actually a problem, more details or a repro would be helpful
(what exactly you did on the client and server, what you expected to
happen, and what actually happened).

Thanks!
