"Crypto Platform Poly Network Rewards Hacker with $500,000 'Bug Bounty'"

White Hacker returns millions in cryptocurrency hacked from Poly Network last week. The company has decided to offer the hacker a $500K bug bounty. The white hat hacker had stated that he/she had initiated the hack for fun—and was motivated to demonstrate a vulnerability in the company’s software. Some companies are offering bug bounties to help identify problems with the systems. The hacker seemed to have used a weakness in the digital contracts that Poly Networked needed to move assets between customer blockchains.
