PermaLeak Protocol

Challenge Description

In this challenge, you'll need to find and exploit vulnerabilities in a decentralized storage protocol to gain access to protected data.

Scenario

You've discovered a new decentralized storage service built on Arweave that claims to be "unhackable." The service stores sensitive data and uses a custom access control mechanism. Your goal is to bypass this mechanism and retrieve a secret file.

Objectives

• Analyze the storage protocol's architecture
• Identify vulnerabilities in the access control mechanism
• Exploit these vulnerabilities to access the protected data
• Retrieve the secret flag

Hints

• Look closely at how the protocol handles transaction verification
• The access control mechanism might not properly validate all request parameters
• Consider how permanent storage differs from traditional storage in terms of data access patterns
