I finished the writeup for “Horizontall” and did user flag for the active machine “Driver” (rated easy). It is a Windows machine where the SMB server can be exploited via file upload. It was rather complicated (for me) and I needed a lot of walkthrough-support, so I didn’t do thep rivilege escalation.
Instead, I started the “Phishing” series on Try Hack Me, which was quite easy but interesting. All in all, I spent around 4 hours.
