TISC 2022 Summary

The Challenge for TISC 2022

PALINDROME was back again with a vengeance. Singapore had another large-scale cyber attack that compromised and disrupted several of Singapore's critical infrastructure and cyberspace.
This year, there was a series of challenges that covered topics from Web Pen-testing, Forensics, Reverse Engineering, Binary Exploitation, Cryptography, Mobile Security and Cloud.

One unique feature that was implemented this year, allowed participants to choose between Track A or B to progress further up the levels. Upon unlocking level 4, participants chose between tackling the Reverse Engineering challenges on Track A or to face the Cloud and Web challenges on Track B. The two tracks eventually converged back on level 6 where participants continued on a linear track again.
TISC 2022 was held over 16 days, from 26 Aug 2022 (2100H) - 11 Sep 2022 (2100H).


PALINDROME operations mostly foiled but 1 got through!

Valiant work and effort by all you worthy cybersecurity experts whom tackled all that PALINDROME had thrown at us! Your ingenuity and perseverance helped in shutting down majority of PALINDROME's operations, but the last major attack got through and PALINDROME got away with $10k cash, that would have much benefited our cyber community.
PALINDROME had since retreated back into the shadows.. and Singapore's infrastructure and cyberspace is safe once again... for now!


730 cybersecurity experts answered the call in TISC 2022 to stop PALINDROME, with 210 solving at least one challenge. Web/Cloud challenge (i.e., Route B) proved to be the more popular route for those who completed Level 4 (43 versus 18). Here are some statistics:
