Decentralized finance (DeFi) platforms Rari Capital and Fei Protocol suffered a more-than-$80 million hack early Saturday.

  • The hacker exploited a reentrancy vulnerability in Rari's Fuse lending protocol, according to a tweet by smart contract analysis firm Block Sec.
  • According to a tweet from Blockchain security firm PeckShield, the same vulnerability has been used to attack other forks of the Compund DeFi protocol.
  • Rari Capital acknowledged the hack, saying borrowing has been paused globally and that no further funds were at risk.
  • Fei Protocol, which merged with Rari in December, offered to let the attacker keep $10 million of the stolen funds as a "bounty" if the remaining funds were returned.
  • Rari Capital suffered from a different attack in May of last year, which saw a hacker run away with $10.6 million in user funds.
