Okay, I passed. I took a sleeping break and ate and starting working on that shit and it worked out. All machines hacked. It was super duper fun and exciting!
My notes were not helping. Practice helps. Whatever you might need, e.g. forgotten a msfvenom command – you have time to google it during the exam. BUT you need to know what you are looking for. Therefore practice is important.
In general I would say it is a hard exam and probably one of the hardest I did. Not so much because of the topics, but because of the restrains you get and time pressure.
Stupid hint, OpenVPN connection wont work on modern systems, you need to allow older protocols by adding:
auth-user-pass pass.txt data-ciphers BF-CBC data-ciphers-fallback BF-CBC tls-version-min 1.0
auth-user-pass pass.txt will read the username and password from the file pass.txt (first line goes username, second line password).
