Live hacking playground and courses

[ayu]

So I recently took the OSCP course and really loved their lab environment.
Apart from the excellent almost 900 pages and 18 hours of video material you also get access to a network via VPN with 50-60 hosts.
There are all sorts of setups available and it's the perfect place to either test or better your skills.

Now, OSCP is quite pricey and it was my company that paid for it for me

So I have found a few really good alternative of which one is free to use by anyone.
This first one is very similar to OSCP.

The one I picked, mostly for economical reasons, is "Hack The Box".
I login from my Kali machine a few times a week to hack one or two boxes and it's really fun and keeps the skills sharpened.
To get an invite code you need to "hack" your way in, or contact them to get the code.
I recommend taking the time to do the hacking route since even if you're really new to this it's a really good first trial.

Hey, nice resources! I figure I'll add a few more here:

They provide a bunch of VM disk images for you to run on your own machine. Each VM has a set of challenges for you to complete, with each challenge listed as a "level" on that VM. The VM's each have around 20 or 30 levels and there are three VM's you can download, each more difficult than the last (so they say).

I found this one a while back and bookmarked it, but I haven't really checked it out much yet. They have a pentesting lab (looks like a set of VM's?) It also seems to have a VPN hacking lab too.

This is a browser-based CTF/game. This is focused on reverse engineering the firmware running on some door locks. It gives you an interface to a disassembler and debugger (yep, right in your browser!) and you have to complete levels of increasing difficulty. I've had a lot of fun with it!

This site provides a bunch of different binaries to practice software reverse engineering.

Yet another hacking wargame/CTF.

Name speaks for itself I'd say. They have a bunch of crypto challenges.

https://backdoor.sdslabs.co/" onclick="window.open(this.href);return false;
They have a variety of hacking challenges.


This isn't really a pentesting thing, but...

This is an online hacking game. Not realistic, but it can be fun ^_^
