Symptai Cyber Challenge: CipherClaus

What is CyberRecon: CipherClaus

CyberRecon - CipherClaus is a Jeopardy-style CTF hosted by Symptai Consulting Limited. Participants will have 120 hours to solve ten reverse engineering and cryptography challenges themed around the holiday season. The challenges will vary in difficulty, requiring a beginner to an intermediate level understanding of reverse engineering and cryptography. Dominate each challenge by being the first to submit flags, as flags submitted will be worth 15% less in points.

What is CTF

Capture The Flag (CTF) competitions are competitive hacking events where participants use cybersecurity tools and techniques to find “flags” and obtain the highest score. In cybersecurity-themed CTF competitions, flags are usually random strings embedded in the challenges. Participating in CTFs is can be worthwhile as they help develop the essential skills required to follow a career path in cybersecurity.
