The BNB Chain-based decentralized finance (DeFi) protocol Ankr has suffered a multi-million dollar exploit. The exploiter allegedly minted 20 trillion Ankr Reward Bearing Staked BNB (aBNBc), a reward-bearing token for BNB staked on the protocol. Since then, the exploiter has used services such as Uniswap, Tornado Cash, and various bridges to swap and obfuscate the funds and raked in 5 million USD Coin.
