RDP Traps ? (lemmy.sdf.org)
submitted 1 year ago* (last edited 1 year ago) by [email protected] to c/[email protected]
 

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 ?

You're looking for a honeypot Be careful with installing something like that with docker(or anything), docker is very unsafe

[–] kylian0087 3 points 1 year ago (1 children)

Docker is not very unsafe at all. Although something like podman would be better.

[–] [email protected] 1 points 1 year ago

It's not as safe as people expect it to be either. Container breakouts are very much a thing and not necessarily relegated to those that did something stupid in configurations

Yeah that was my question. I never mentioned docker though ?

Is there a linuxserver.io but for infosec?

[–] rookbrood 1 points 1 year ago

No idea, I like to build/make my own.

[–] [email protected] 1 points 1 year ago

That's more of a framework for RDP right ?

[–] [email protected] 2 points 1 year ago (1 children)

you can use iptables tarpit target. it works on the transport layer so it should work with any application layer protocol.

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 !
