Around $620 million were stolen by the hackers in one of the biggest crypto theft in the world from Ronin, a blockchain network connected to the popular Axie Infinity online game.
The Ronin hack comes after more than $300 million worth of cryptos were lost in the February attack on the Wormhole bridge.
Like any system, cryptocurrency platforms and exchange mechanisms are vulnerable to cyberattacks. As per a report, a 51% or majority attack is where an attacker gains control of more than 50% of the hashing power of a blockchain. Once a hacker has that level of control over the blockchain, they can perform double-spends and reverse transactions.

1. Ronin | $625 million: The makers of one of the most popular blockchain-based online games, Axie Infinity, said Tuesday that hackers were able to steal assets worth about $625 million from the gaming company and its players.
