This market has since the DeFi boom, making it the target of more hackers than any other sector in cyberspace. I think that perhaps many projects have lacked the care when they still let the contract errors repeat many times. I have heard about a number of different tricks like price manipulation and project exits, but more realistically the recent attacks are targeting a lot of large projects and the amount of money lost is huge. Perhaps a change in product developments is required before users can use it, unfortunately for us, trusting the use of the product does not guarantee the safety of the property.
