Rari Hacker Steals $80M
The DeFi house has been hit by one other main exploit. This time, Rari Capital and Fei Protocol are affected.
On-chain knowledge exhibits {that a} hacker stole about $80 million from Rari’s Fuse lending swimming pools early Saturday.
Persevering with a development seen in lots of different DeFi assaults over the previous 12 months, the hacker exploited what’s referred to as a reentrancy bug, a type of sensible contract exploit that primarily permits an attacker to trick a protocol into letting them withdraw an extra provide of tokens they don’t really personal.
Rari’s Fuse swimming pools run on Ethereum’s sprawling DeFi ecosystem. They provide a technique to create remoted lending markets for every kind of tokenized belongings, one thing that isn’t provided by many different bigger, extra liquid lending protocols. Considered one of Fuse’s key customers is Fei, one other DeFi protocol that’s greatest identified for creating the FEI stablecoin.
