About JCTF
JCTF is one of the leading Israeli CTF teams, consisting of cybersecurity researchers,
software engineers, computer science students, and security enthusiasts.
The team was originally founded by Dr. Arie Haenel and graduates of
his software security course at the Jerusalem College of Technology (JCT),
and today is composed primarily of JCT graduates and students, with a small number of members
from outside the institution.
We believe that solving challenges is a great way to learn and stay up to date, especially in
areas that we don’t usually work on in our day-to-day routine.
This website contains writeups for CTFs we’ve participated in, documenting our approaches and solutions,
and shared for learning and reference purposes.
