Learn about data privacy vulnerabilities in Solana smart contracts through this CTF challenge.

This challenge focuses on the privacy aspects of smart contract data storage on Solana. You'll explore how seemingly private data can potentially be exposed and learn techniques for secure data handling in blockchain environments.

Challenge Goals

• Understand how data is stored in Solana programs
• Identify common privacy vulnerabilities in smart contracts
• Learn techniques to securely handle sensitive information
• Develop exploitation skills for identifying data leakage

The challenge was originally presented at ALLES CTF 2021 and provides practical insights into the security considerations necessary when handling private data in public blockchain environments.
