The InfoSecurity Challenge (TISC) is proudly organised by CSIT.

What is TISC? 

TISC is a two-week online sequential style Capture-the-Flag (CTF) competition organised by CSIT since 2020. It provides opportunities for interested Singaporeans to put their cybersecurity and programming skills to the test by solving challenging puzzles against the clock.
There will be a series of challenges for participants to complete, sequentially, in increasing level of difficulty. The levels will cover various topics including, but not limited to, Web Penetration, Forensics, Reverse Engineering, Binary Exploitation, Cryptography, Mobile, Cloud and OSINT.
