Security Challenge by Hellenic Cyber Security Team
kindly offered byHellenic Cyber Security Team, University of Piraeus and Sealed Grid
Date / Time: Friday 2 December / 15:10-16:30 EET
In this short Capture the Flag (CTF) competition you will be asked to compete against each other in solving four security related challenges in about one hour. To solve a challenge, you may have to analyse digital files, reverse engineer binaries, crack hashes, break cryptographic algorithms or exploit programs’ vulnerabilities.
Three of the challenges will be offline and one will be online. For the offline challenges, you will have to download the challenges’ files and analyse them locally on your computer to recover the embedded flags. For the online challenge, you will be given access to a vulnerable service which you will have to hack and recover the hidden flag.
During the competition the CTF organisers may change the pool of available challenges if any problem occurs (e.g. network problems) in order to keep the competition running.
Get ready, setup your Linux VMs, install your network analysers, fire up your reverse engineering tools and don’t forget to bring your exploitation cheat sheets. But remember… do not share flags, do not attack machines that are not part of the competition, do not attack the competition infrastructure, you may brute force only offline challenges, and of course have fun!
