Interests
Outside of coding, I love being outdoors. Mountain biking, climbing, bouldering, and hiking are some of my favorite activities.
Gaming is another passion of mine, especially Minecraft. I also enjoy playing Rust, Euro Truck Simulator 2, Scrap Mechanic, and BeamNG.drive, both solo and with friends.
I also actively participate in playing Capture The Flag (CTF) competitions. Want to read some of my Writeups? Or see my CTF Toolbox?
AbuseIPDB - IP Address Blacklist
I run Fail2Ban on all my servers, using it to monitor and block suspicious activities, particularly for SSH and web services. When Fail2Ban detects an intrusion attempt, I report the offending IP addresses to AbuseIPDB. This helps inform others in the community about potential threats, contributing to a broader effort to enhance online security.
