# The InfoSecurity Challenge 2022

[TISC 2022](https://www.csit.gov.sg/events/tisc/tisc-2022) was hosted by the Centre for Strategic Infocomm Technologies (CSIT). This year, I authored a challenge (5B - PALINDROME's Secret) but also had the opportunity to try out the challenges leading up to it! Here are the writeups.
