N4TH0WL — an animated pixel-art rooftop at midnight, with a full moon, drifting clouds, shooting stars, passing buses and cars, and an owl beside a teal vending machine under a bus-stop roof.

Ivander Nathanael K. / N4th0wl

CTF player and security researcher. Cloud and cybersecurity enthusiast. I like figuring out why something works, and where it stops working.
