Today I read the news of the most shocking events at https://www.reuters.com/technology/defi-platform-poly-network-reports-hacking-loses-estimated-600-million-2021-08-11/ namely news about The biggest hack in the history of the crypto industry. A cryptocurrency platform has lost about $600 million in digital tokens after one of the biggest hacking attacks in the sector, according to details of the theft that emerged on Wednesday. Why this event can happen so as to create space for hackers, it's really unfortunate
This is a sad thing for the crypto world. But I it happened because of PolyNetwork's weak security. So I think the security system of the polynetwork should be further improved so that such incidents do not happen again in the future.
