The BNB Chain-based decentralized finance (DeFi) protocol Ankr has confirmed it has been hit by a multi-million dollar exploit on Dec. 1.
The attacker was purportedly able to mint 20 trillion Ankr Reward Bearing Staked BNB (aBNBc), a reward-bearing token for BNB (BNB) staked on the protocol. The exploiter has since used services such as Uniswap, Tornado Cash, and various bridges to swap and obfuscate the funds and has successfully gained around 5 million USD Coin (USDC)
