Summary

The Money Flowz Challenge on Hack The Box is an easy-level OSINT challenge that involves tracking cryptocurrency transactions to extract hidden information. Participants investigate the online presence of “Frank Vitalik,” uncovering relevant blockchain addresses and transaction histories on platforms like Etherscan and WebArchive. By analyzing archived Ethereum transactions from the deprecated Ropsten testnet, they locate the flag embedded in the transaction’s input data, which can be decoded using UTF-8 format. The challenge highlights the importance of blockchain forensics and demonstrates how public ledger transparency can be leveraged for investigative purposes.
