Grok了一下Balancer V2被黑的原因,原来是金库合约存在权限漏洞被重入攻击了。
除了重入攻击,黑客常用的DeFi协议攻击方法还有预言机攻击、治理攻击、精度溢出攻击等。
DeFi Summer以来,rekt网站统计的黑客洗劫DeFi和跨链桥的资产规模有200多亿美元了。
有时候,真怀疑不安全是EVM的技术特性😂
Balancer exploited for over $110M along with forks on multiple chains, TLDR:
-> Balancer v2 pools are impacted, v3 is safe
-> other BL forks are also affected, Total loss on different chains:
Eth: balancer, 70m
Base: balancer, 3.9m
Polygon: balancer, 117k
Sonic: beets, 3.4m
Arb: balancer, 5.9m
OP: beethoven, 283k
-> there are around 27 forks of BL acc to defillama
-> exploiter address keeps being active, creating new contracts and sending custom ERC20 tokens
-> root cause is still not clear
