I’ve recently dug into my firewall logs and the most traffic I seem to receive from internet is targeting port 3389.
While I could just blacklist the source IPs and call it a day, I would like to actually listen on this port and “trap” them in a fake RDP connection.
There are tools like endlessh, and I’ve found that you can do the same for http by sending an endless stream of headers. I would like to do the same for RDP, and before I start digging into the whole spec, I was wondering if there is already something similar for RDP.
Is anyone aware of that ? Is that even a thing ?
I didn’t know there was a tarpit target for iptables, that’s neat. Unfortunately I run OpenBSD and pf so I can’t use it, but I’ll look into how it works to see if I can replicate it in my setup. Thanks !
