CyberShock CTF 2021 was provided by CybExer Technologies & CTF Tech (EE) within CyberShock 2021 conference, organized by CERT.LV. The event took place from 6th of October, starting at 09:00 (UTC+3), until the 7th of October at 17:00 (UTC+3). This CTF was in style of jeopardy & infrastructure takeover. Tasks were split in three categories - bronze, silver, gold. Only 5 tasks could be open at a time. Taking hints or leaving open task gave point penalty. Participated 31 teams with maximum up-to 5 members per team.
Our team participated remotely, and we finished 1st, solving all-ish* (one of the challenges was broken for us) and receiving 3175 points. Prizes were provided by CyberCircle and we each received HackRF One. Unfortunately, without antenna ;)
