Be careful anyone who tries to solve this challenge, Ethereum is known for having honeypot contracts/addresses - something that looks vulnerable to hacking, but actually steals the money whenever you try to hack it. This challenge requires you to send your money to an address that immediately drains it, so don't send more ethers than you can afford to lose.

I'm not saying here that the OP is a scammer, maybe they just shared what they saw somewhere else, but anyway be careful.
