Here you can find writeups from various CTFs that I've participated in. |
In case you don't know what CTFs are, here's a nice definition:
A capture the flag (CTF) contest is a special kind of cybersecurity competition designed to challenge its participants to solve computer security problems and/or capture and defend computer systems.
I play CTFs with Social Engineering Experts and Water Paddler.
Social Engineering Experts is a Singapore-based team founded by a group of friends. We're always looking for active players to join us — check out the recruitment form in our CTFtime profile.
