On 10th August 2021 the Poly Network was attacked and had $600m of Ether based crypto taken from it. The hacker later returned those funds whilst also providing a justification for their actions. This can be read below:
The 13.37 Tip was given to a member of the crypto community for telling the hacker that the Tether (USDT) he had stolen was blacklisted and could not be used
Nice of the hacker to return the funds! PolyNetwork lives to fight another day.
Until Next Time
