DeFi platforms are still subject to hacks and attacks, even after passing security audits. Some teams seek to secure user funds or recover losses, but there is no complete guarantee of security. As DeFi projects increase, there will also be more hacks despite advances in technology and security, so either take the risk or don't invest.
Seems like it. But even having security audits can still be at risk for some defi product. Well lets say that black hat hacker are way smarter than them and able to manuever their defense.
Its not that easy to find an exploit with those smart contract its just that these guys are way trying hard to make this possible to a point they need every loopholes just to secure a perfect exploit.
