Loving the ProxyJump feature in #OpenSSH. Super easy to replicate ZFS datasets offsite without additional layers that a VPN would introduce for no real benefit.

Just read a great write-up by @[email protected] on the 2002 OpenSSH trojan incident.

It's a fantastic look at early incident response, code auditing, and how OpenBSD handled one of the first major software supply-chain attacks.

Definitely worth a read:

I created a presentation and a Docker-based hands-on lab in which you can learn how SSH works, how it can be attacked and how to protect it: https://sshlabs.compass-security.training/ #security #infosec #network #ssh #openssh #pentest

That moment when #OpenSSH takes minutes to connect and even a "clear" takes almost 10 seconds to execute.

What the f crashed/locked-up and wtf?!?

Let's see how long it takes for htop to start and tell me...
