Beat The Clock: The CSIT InfoSecurity Challenge
Introduction: Red Alert!
Last month, the Centre for Strategic Infocomm Technologies (CSIT) invited local cybersecurity enthusiasts to tackle the InfoSecurity Challenge (TISC). The Challenge was organized in a capture-the-flag format, with 6 cybersecurity and programming challenges of increasing difficulty unlocked one after another.
On New Year’s Eve, hackers from the PALINDROME group launched a ransomware attack on a major finance company and encrypted some of its critical data servers. Your mission is to complete a series of tasks to recover as much data as possible to prevent the company from having to give in to PALINDROME's demand. The tasks will increase in difficulty as you go along so be prepared to put up the fight of your life.
With this exciting introduction, I tackled a series of difficult problems that encompassed reverse engineering, binary exploitation, and cryptography. This took me far out of my comfort zone of application security, but since I wanted to build my skills in those areas, it was a welcome challenge.
