Learn crypto through hacking
CCTF is the largest hacker competition for crypto/blockchain hackers. The authors focus on creating realistic challenges that cryptographers, auditors, pentesters and security engineers face on a daily base.

Story and past CCTF events
The vision of CCTF was created at the beginning of 2019 by Six and the first round was played during the BsidesBUD information security conference. Since then, each event started with an increased number of participants and sponsorship awards. The main organizers are Six and Silur. They work together since CCTF Volume 3. and work hard on pushing the limits of the event forward. CC7F will have even more challenges and the winners will be awarded from a $15000 prize pool.
Topics of the game from the past: cryptography, blockchain, Proof of Authority, Smart Contract security, frontrunning and cryptocurrency infrastructure vulnerabilities, weak crypto, misconfigurations, leaked wallets, BIP seeds, incorrect RSA implementation, polkadot, ethereum, bitcoin.
