# The InfoSecurity Challenge (TISC) 2021

Here are my solutions for The InfoSecurity Challenge (TISC) 2021, a Singaporean CTF organized by the Centre for Strategic Infocomm Technologies (CSIT).

The challenges were definitely quite interesting. I didn't spend as much time on this competition as I would have liked, but I did well enough to receive some swag!
